Five Things to Consider for When Selecting a Camera System Component, Package, and Company

When shopping for a security camera system, its very easy to fall into any of the traps set by good marketing and advertising. You have to navigate through oodles of jargon and flat out lies in order to even start your decision. Here’s a few ways to tell whether or not you’re getting a good system from a reputable company (and no. Just because a company is “big” doesn’t make it either a good system, or the makers/marketers any more reputable).

1) Tech Support. Quite possibly the biggest factor. It doesn’t matter how amazing the picture is, or the quality, or anything else. If the manufacturing company doesn’t offer accessible support, you’re eventually going to be very unhappy. All things technical eventually, if not immediately have an issue. You want to make certain that you can actually reach someone in the event of an issue. Make sure there is more than one method as well. You want options like email, forums, phone lines, and online resources. Perhaps even go as far as give it a test run. Pretend you’ve had an issue before you’ve even bought something. What are you going to do? Can you find email contacts? Are there frequently asked questions sections in their resources? Can you get through to tech support? Does anyone answer the phone numbers provided? If you have a problem at any point, you want to be able to get it resolved. Support contact is imperative.

2) Warranty. Actually, not just if it has one either. Warranties are only as good as their usefulness. Some warranties don’t actually cover anything. Also, some are flat unclaimable due to the fact that there is no one to contact if or when the system has an issue. If a company has two different warranties for two different products, there is most likely a reason for that. There are obviously differences between tiers of products. You really want a two to three year warranty if you can find one. Some companies offer five, six, seven, and rarely more years of coverage. Again, this could be because they stand behind their product, or it could be because they have no intention on being around when it comes to pay the piper. Be leary of excessive warranties. One or two years is the standard. Low voltage electronics are not designed to last this long due to the fact that they are typically out of date technically in under three years. Essentially; you’re most likely going to want to replace them in two to three years anyway.

3) Value. Bang for the buck. No one likes the feeling they get when they buy a system and find out next week it went on sale, got discontinued or closed out, or is comparable (if not exactly the same) as another system for less money. Contact the company selling the system and find out these things. Also find out what is actually inside the machine. There aren’t a lot of chip and processor companies out there. The likelihood that you can find the exact same components on the market in another housing is very very good. Don’t base your entire decision on this, but use it as a “tiebreaker”. Companies do not usually support products their competition have sold, even if they are exactly the same. Just because you got a great deal doesn’t guarantee your long term happiness. What I find to work (often) is simply ask the company you like more to meet/match the price. They most likely are already familiar with the competitor. They may not match it all the way, or be happy about doing it. But they will most likely give you a price that will at least satisfy your pocket.

4) Future-proof. This actually goes more for the infrastructure involved with your system components. Often people are concerned about how long their components will last, and not at all about the cables and connectors that are involved. You really must consider this element as critical. As technology gets phased out, it becomes scarce. IDE hard drives are an excellent example of this. This was the standard for years, and within a single year they pretty much disappeared to the successor (PCI). Now its nearly impossible to find them. This too is somewhat true of the cables involved. You may think “big deal, cables are cheap”. However, your time isn’t. Even worse if you need to pay someone else to do the work. Being able to use your cables for future systems is probably going to save you a bundle later. Try to choose a cable type that can be used for something other than cameras (like Cat 5 or Cat 6). This will increase the likelihood of you getting future usage from them.

5) Knowledge. This is another common sense factor that often gets overlooked. The market is full of importers and warehouses. Yes, you can most likely get a deal from them. However don’t forget to consider the amount you know about security camera systems. A discount computer is fine, due to the fact that you’ve most likely owned several dozen and are also most likely well-trained on the operating systems they work in. But have you spent the same amount of time working on camera systems? Choosing a company that knows its products can save you massive amounts of headache in the long run. Checking their website may give you some insight as to whether or not they know what they are selling. However, too often material on websites gets stolen, reworked and reworded, and then re-posted again. You really need to contact the company. Use several methods. Call them. Email them. Fax them. Use the methods you prefer. Do a little discovery to see what other contact and information forms they may have. A running forum perhaps? An active and updated online database? A video database? A YouTube Channel? All of these things can and will help you acquire knowledge quickly and efficiently when you need it.

Clearly the quality, capability, and performance of the equipment you choose is important. But also is being able to learn how to use it, getting it repaired or replaced, and upgraded. In today’s market, there are so many good (and bad) alternatives that you really need to consider the place you purchase from as much (if not more) than the equipment itself. After all, you may save 50% on your purchase. But what good does it do you if you can’t use it at all?

How to Capture License Plates with Security Cameras

Capturing License Plates With CCTV Surveillance Cameras

Using a surveillance camera to capture video footage of the license plates of vehicles that are entering and leaving an area has proven to be an effective way to have a record of the traffic at the location. Law enforcement agencies across this country are making use of this technique more and more commonly. It has already helped them to gather information that has helped them follow vehicles thought to be driven by individuals that were suspected of crimes, even when the officer is nowhere near the vehicle. The data that these cameras provide can be invaluable if a crime takes place, allowing someone to review footage and know who was in the area with certainty. The data collected about these license plates can be more helpful to law enforcement officials when trying to identify a suspect then the highest quality images of a suspect’s face. The installation of security cameras for this function may seem deceptively simple but if it isn’t done correctly you will not get the video that you need. This article will provide with the information that will you to accurately record video footage of license plates every time.

The first consideration that you should look at for licenses plate capture is the location. Finding the right place to record useful video of these small fast moving targets is a key element in the process. The place where you set up for this should be a place where traffic is already controlled in such a way to be beneficial for this process. Someplace where traffic is already forced to stop, such as a stop sign or the gate of a community, is an ideal spot. The entry way of a gated community is probably the best location because it will also be a place where there are fewer lanes of traffic and you will need a dedicated license plate capture camera for every lane of traffic that you’re monitoring, so fewer lanes will require fewer cameras to get the video footage that you want.

The next thing that you should consider for this process is making sure that you have the proper equipment to record the best possible video of the license plates. There are many different security cameras on the market today that offer high quality video, but few are actually designed to record high quality video of a license plate. The cameras that perform this function correctly have to be able to deal with the glare of light bouncing off the reflective surface of the plate, angles that are often challenging, widely varying illumination levels, being able to record video of a moving target that isn’t blurry and they usually have to cope with moderate to long distances. All of these factors, in addition to other location specific issues that haven’t been mentioned, that the camera must deal with are the reasons that you really need to have a surveillance camera that is specifically designed to capture video of license plate despite the difficulties.

Another part of this process that you must account for, in order to do it correctly, is properly monitoring the area where you will be identifying the license plates as well as providing an exterior view of the vehicle. A camera that can capture video of the car or truck and its activity will provide you with some very useful information particularly when you can identify the vehicle’s license plate at the same time. Making sure that you at least have a reasonable high resolution camera for this overview purpose is a very good idea, but it doesn’t need to provide the same type of high quality of video that the license plate camera should. A moderately high quality camera for the overview role will allow you to have a high level of detail in the video shot to help you get an accurate understanding of what type of vehicle the license plate is attached to and how many passengers are in it. This over view camera can also provide other details about the vehicle such as the relative speed that it’s traveling and whether it’s being driven recklessly or not. It’s also a good idea to get a camera for this purpose that has a varifocal lens so that you can adjust it to the camera view that’s needed from the position that’s available for mounting the camera. This type of lens will let you compensate for a reasonable amount of distance from the targeted area and make sure that it’s focused on the exact point that you want.

So now we have established that an overview camera needs to be mounted in such a way that it can view the traffic choke point where you are going to be capturing video of license plates. The next step is to make sure that you have the surveillance camera that will actually be doing the license plate capturing in the right place. The traffic point that you choose for this installation should allow you to know where the target vehicle will stop. The license plate capture will need to be positioned in such a way that it’s field of vision will be focused and the lens will need to be zoomed in to the point that the license plate will take up about sixty percent of the camera’s view. Make sure that you take into account the varying heights of the different types of vehicles that will be traveling through the area. You will need to have one dedicated license plate capturing camera set up this way for each lane of traffic that you wish to monitor.

Once you have these cameras set up in the manner that’s described in this article, you should be ready for monitoring the traffic in the area in great detail. It’s a good idea to test how the camera views will catch the license plates where the vehicles will be stopped and the make the fine tuning adjustments in order to guarantee that you will be getting the video that you desire.

Basic Port Forwarding for the DVR & NVR

Written By:
Wednesday, June 12th, 2013

security system support groupsToday we will be exploring a simple world of port forwarding. For those of you who like to be hands on and grasp the “What, Why, and How to do” or you simply want to complete this segment of your job or project and Tech Support is unavailable I welcome you to proceed reading. I will begin with, “Make sure you have a PC, DVR/NVR, router and/or modem all [plugged in and ready to go. Also please obtain all passwords to each device (if necessary) to ensure flawless setup as we go from procedure to procedure. Once you have done so please access your START MENU on your PC.

basic port forwarding for nvrs

{Depending on what operating system you have, the above picture may vary.)

Choose the RUN option and then type in the command CMD. Then hit the enter key and you should have a window like the following:

setting up your security system

In this window, type in the command IPCONFIG and hit the enter key, this will pull up your LAN (Local Area Network) IP scheme. The one you will see my network in is a 192.168.1.xxx scheme. If yours is different, PLEASE DO NOT DESPAIR**, following along with the same process while subsitutuing my scheme with yours, will provide you with the SAME results. You should have now the following window:

As you see in the picture above my gateway 192.168.1.1 (which is my network scheme). The IP address of the PC I am using is 192.168.1.104. This is the unique IP belonging only to my device (my computer). This is the name, if you will, that the LAN knows my PC as. Every device that is attached to my network is issued its own unique IP address. Now our DVR/NVR and IP Mega Pixel cameras all have a default IP address of 192.168.1.108. On my network 192.168.1.108 is already taken so I will establish the IP of the DVR to 192.168.1.120. I suggest anyhow, to always change the IP address of any our devices to a known open IP on your network. You can see if an IP is open or not by pinging your network. You can check this in Command Prompt by typing in PING (hit the space bar once) and then the desired IP based on your established scheme. It will look like so:

how to manage your security system

(Above you can see this IP address is assigned to another device due to the com packet replies)

(Above you can see the IP address is not in use)

Now that we have established an open IP to assign to the device lets change it. If you right click on the mouse of the DVR, chose the following:

Main Menu -> Settings -> Network. Configure your network to the chosen IP in the IP address field. Make sure to change the Default Gateway in the respected field as well if your network requires. While we are still in this menu, let’s go ahead and assign our desired ports for the HTTP and TCP. I for instance will change the HTTP to 88 and keep the TCP port as it defaults of 37777. I now will save my configuration. (If the DVR prompts you that it wants to reboot, this is fine and a necessary function. Just hit okay.) Now let’s move onto creating PORT FOWARDING rules on our network. Normally you can just open up any browser and type in the DEFAULT GATEWAY of your IP scheme. Please refer to the picture below:

how to set up port forwarding for NVRs

(Before)

(After)

I will now access my router by putting in the password. Once Inside I can now create port forwarding rules for my device. Based on your router and/or modem the following pictures will not look the same. The current router I am using is a Linksys 1750AC.

(Main Menu once you log into the Linksys 1750AC)
single port forwarding for security cameras

I will now go to the Security tab at the bottom left hand corner, then choose the APPS & GAMING tab, and then SINGLE PORT FORWARDING.

As you can see in the above I have created (3) different port forwarding rules for the IP address 192.168.1.120 which is my DVR. You WILL have to only create two, the HTTP PORT & TCP PORT. Once completed be sure to save the configuration and now let’s check to see if our external is now connected to our internal with this two ports. We are going to proceed use a website known as: CanYouSeeMe.org

I hope you got the same results as I did! If all was successful you ports should have shown a SUCCESS: I can see your service on (your external IP here) on port (your desired port you choose). If not, again do not despair***, please try following the same process over or contact us for your free technical support on OUR products. Please see the below for the DVR view on a browser:

How To Find The Best Wireless Security Camera For Your Home

Written By:
Thursday, August 16th, 2012

Wireless security cameras are designed for both indoor and outdoor use. A wireless camera requires no wires between the camera and the receiver. They are easy to install and can be moved from one location to another. Wireless cameras are available in many sizes and forms. The cameras capture black and white, color and infrared images. The security system connects to any computer, television or digital video recorder for easy viewing. To find the best wireless security camera for your home, decide how many cameras you need.

If you want to monitor the entire perimeter of your home, then you will need several cameras. Consider the image quality when choosing a camera. An HDTV camera has a higher resolution and will cover a larger area than a CCTV or an IP camera. The benefit of an IP camera is the fact that you can connect multiple cameras to your digital video recorder. IP cameras can connect to the Internet providing remote viewing from any computer. An Ethernet switch provides the power and the Internet connection. HDTV cameras are useful when you need to capture clear and precise images such as license plates or faces. Today’s technology allows home security systems to be enabled or disabled by using a computer or smartphone.

To monitor the inside of your home, you can install burglar alarms on your windows and doors. Carbon monoxide, fire and flood alarms can easily be added to your home security system. Carbon monoxide is known as the silent killer because it has no smell or taste. Heat detectors are useful in areas of the home such as laundry rooms, garages and other places. Fire alarms can be monitored by a security company to contact you or the fire department. Flood alarms are used to detect the presence of water or moisture in the event you have pipes that burst or leak. They also monitor moisture levels to warn you of the presence of mold and mildew. Inspect these sensors on a regular basis to prevent the buildup of dirt and debris.

Home burglar alarms are helpful because they alert you to the presence of an intruder whether you are home or not. If you choose to have your burglar system monitored by a professional security company, they can install glass break sensors on your windows. They use single or double break technology to detect glass breakage. Single break technology will trigger the alarm from the sound of glass breaking. Double break technology must hear a thumping sound followed by the sound frequency of glass breaking before the alarm is triggered. Monitored home burglar systems may have to be adjusted to prevent false alarms. Many cities have penalties for frequent false alarms. False alarms cause local law enforcement to use resources that are needed elsewhere in the city.

Emergency health response systems are a good choice for people who have health problems, the elderly or just for the peace of mind. These emergency response systems can alert local authorities to the presence of a medical emergency inside your home. Panic buttons are located on the home security system’s keypad and also by small remotes. You can choose to have the system contact you or the local emergency personnel. There are hidden indoor security cameras that can monitor your babysitter or any situation. These cameras are small and discreet and provide helpful information. They connect to a small digital video recorder and can be wired or wireless. Consult a professional home security company to determine which security system will work best in your home.

Combining a home security system with home safety tips will improve the security of you and your family. Don’t hide a key under the door mat or anywhere else near the home. This will be the first place a burglar will look. You can buy locks for your doors that require opening with your fingerprints. This is a good idea if you are constantly losing your house keys. If one of your locks on your door breaks, be sure to replace it right away. Two cylinder locks are available but they require a key to open the door from the inside and out. This can cause a hazard if there is an emergency in the home and you need to leave quickly. Install deadbolt locks on sturdy doors that lead into your home. The deadbolt should be attached to the door’s wood frame. Have a professional install your deadbolt locks if you’re not sure how to install them. Access doors into your home should be made of steel, wood or fiberglass. This will help prevent a quick entry into your home by simply kicking it. Install modern kick plates on doors leading inside your home. Hollow doors without good locks are easily kicked in by burglars.

Outdoor lighting can improve the look of your home. It also helps to deter crime. Most burglars don’t want to be seen and they like the cover of darkness. Install solar lights and motion detection sensors to lower your energy bills. If you have a privacy fence, you can add a beware of dog sign even if you don’t have a dog. Place home security signs and decals on your windows and doors to alert a possible intruder that you have security. You can also purchase fake security cameras that look like a real working home security camera. Driveway and garage sensors can be installed to detect movement. Keep the garage secured and locked at all times. Don’t leave the garage door open even when you are at home. This gives people who pass by the opportunity to stake out your garage. Lock the inside latch of your garage door with a padlock. Check your garage door remote to be sure it has rolling code technology. This technology changes your garage door code each time you enter the garage. If you must replace your garage door, choose one without windows to prevent a burglar from seeing if there is a car parked in the garage.

When you have a home security system installed, be sure to keep it activated even when you are at home. Many people either don’t turn it on when they are home, or they forget to activate it when they leave. The key to protecting your family and home is to use the alarm system. It only takes an intruder a few minutes to enter your home and steal your possessions. Most burglars are looking for items that can be sold at the local pawn shop. Be sure to have your driver’s license number engraved on your expensive electronics. The burglar won’t be able to sell your items very easy. Keep curtains and drapes closed so they don’t reveal your home’s contents. Install sensors on all of the windows of your home. If an intruder tries to enter through the windows, an audible alarm will sound. This could be enough to send the burglar to another home.

Store your valuable jewelry, cash and weapons in a locked safe or a safe deposit box. If you purchase a safe for your home, you don’t want a burglar to be able to carry it out. Have it bolted to the floor, or be sure it is too heavy to be carried easily. The outdoor storage shed should be kept locked at all times. Installing electronic gates will help to keep a burglar out of your backyard. If you have a privacy fence, a burglar can get into the backyard and remain invisible to the neighbors. Get to know all of your neighbors in your neighborhood. Join your local crime watch program or start a new one. Most law enforcement agencies have crime prevention programs that you can join. Learn about the crime risk in your area. When you go on vacation, notify a neighbor to watch your property. Install timers for the inside lights of your home. This will make your home look like someone is home even when they’re not. If everyone in the neighborhood becomes familiar with who should or shouldn’t be there, then the community is safer. Most burglars will park down the street before walking up to your home. Neighborhood watch programs teach people to report suspicious vehicles.

Apartment and condo residents have the same security needs as anyone living in a single-family home. When you move into an apartment or condo, have the maintenance staff change the locks. You don’t know whether the old tenants still have a key or not. Getting to know your neighbors is important. Report any suspicious people or activities to the neighborhood’s security team or local law enforcement. Reinforce sliding glass doors with a wooden bar, and never leave your doors unlocked. Purchase renters insurance to cover your possessions in case they are stolen. Don’t go to the laundromat at night, and be sure the apartment’s parking areas are well-lit. Ask the staff if you are allowed to install a security system in your apartment. Call a professional burglar alarm service to install the security system.

When you purchase new electronics don’t put the boxes out with the regular trash. This will alert a possible thief to the fact that you have this item. Break the boxes down and place them in plastic garbage bags. Online social media sites are a great way to show family and friends your vacation photos. They can also be a tool for an intruder to know that you’re out of town or when you will be leaving. It’s hard to imagine but the risk is still there. Take care about who you tell about your vacation plans. Leave a spare key with a trusted neighbor or family member. Have them check on your property while you are away. They can pick up your mail, newspapers and any flyers attached to your door. It would be ideal for them to open the drapes in the morning and close them at night. You can also ask your neighbor to park their vehicle in your driveway. You want to convey the message that someone is at home.

If you are selling your home without the use of a real estate agent, there are a few security precautions you should keep in mind. Show your home by appointment only. Don’t set an appointment to show your home when you are alone. When you decide to have an open house, clear the rooms of valuables and electronics. It’s best to sell a home with a minimum amount of personal possessions. If you use a real estate agent and they want to place a virtual tour of your home on their website, then be sure there are no expensive items or electronics in view. Some criminals check these out to choose a property to burglarize later when no one is home. If you are buying a new home, have the locks changed as soon as possible.

A safe room is a room that is reinforced with a lot of concrete and steel. They are used for emergencies such as bad weather or a home intrusion. Adding a safe room to your home will improve your home’s security plan. Keep bottled water, snacks and a cellphone in your safe room. A phone that is connected to a land line is also helpful to phone the authorities from inside the safe room. A land line phone will give your home address to local law enforcement agencies just by dialing 911. If an intruder enters your home, you can run to the safe room. Teach family members about home security safety tips and the use of the safe room. Search the Internet to learn more about installing a safe room in your home. There are many ways you can improve the security of your home. When you combine many security techniques they become a powerful deterrent for an intruder. If you make your home difficult to enter, and you have outdoor surveillance equipment, an intruder may decide to go to another home.

Network Security Camera

Written By:
Thursday, August 2nd, 2012

Although property crime statistics in the United States are steadily declining, according to Federal Bureau of Investigation, there is still a great need to safeguard your property. Whether you’re interested in adding security to your home or business, network security cameras continually monitor your property. While homeowners may feel security cameras are specifically made for businesses, by visually monitoring your home you not only ward off potential crimes by the sheer presence of the camera, but in the unfortunate event of theft or burglary the videos may help law enforcement identify and capture the thieves. Although there are a wide array of security cameras on the market, few offer the security and flexibility as network security cameras. If you’re in the market for security cameras, you should consider installing these items not only for their reliability, but also for the peace of mind their presence provides.

What is a Network Security Camera?

  • Network security cameras, also referred to as IP cameras, have the foundational purpose of traditional CCTV, or analogue, cameras; however, their method of sending and receiving data is much different. In a foundational sense, network cameras are quite similar to webcam as network cameras utilize the Internet to transmit and store recorded images. However, the similarities between webcams and network cameras end there. Network cameras are separated by two primary categories: centralized and decentralized cameras. The following are the two primary differences between these two camera setups:
  • Centralized Network Camera – A centralized network camera is one that requires a central NVR, or Network Video Recorder, to manage incoming recordings, video storage and alarm sounding if the cameras are attached to an audio alarm system. Commonly mistaken for a DVR, an NVR is a software program designed to record and store video from a network camera in a digital format. These digital videos are then saved to some form of digital mass storage such as a USB flash drive or an SD memory card. Although an NVR is solely software, the actual software is typically stored on a dedicated device that connects to various network cameras. The primary difference between an NVR and a DVR is an NVR receives its incoming video signals from an Internet network while a DVR receives its video signals from a direct connection to the camera. Another distinct difference between these software programs is how videos are processed and encoded. DVRs process and encode videos after they are streamed to the unit while NVRs process and encode video signals before being sent to the recording device.
  • Decentralized Network Cameras – A decentralized network camera is one that does not use an NVR. Rather, these cameras feature built-in video storage capabilities such as hard disk drives or flash drives. This form of storage is more streamlined, but features limitations such as not being able to store large quantities of data.
  • Types of Network CamerasNetwork security cameras are available in a wide array of formats and designs. However, while there are many designs there are seven primary camera types. Manufacturers may alter the features within these camera types; however, every network security camera is based in one of the following.
  • Outdoor Cameras – Designed specifically to be used outdoors, these network cameras feature weatherproof casings, significant temperature operation range, day and night recording as well as a tampering alarm. Typically used to monitor parking lots, campuses and traffic conditions, an outdoor network camera is ideal for areas that require 24/7 monitoring in all weather conditions.
  • Thermal Network Cameras – During moments of complete darkness, thermal network cameras are able to clearly capture images based on heat radiating from objects. All objects radiate a certain amount of heat, and this camera type is designed to capture the details from a heat source. The primary benefit of this camera design is its able to monitor property in complete darkness. Therefore, there’s no infrared LED lights illuminating the area. In complete darkness, onlookers are unaware they are being monitored. The downside of this camera design is its lack of detailing. While figures are clearly seen, small details typically captured by infrared security cameras are lost.
  • Megapixel Network Cameras – These cameras are designed to capture highly detailed images. Designed with the latest in high resolution surveillance technologies, megapixel network cameras, also referred to as HDTV cameras, can clearly record facial features or items a customer purchases.
  • Covert Cameras – As its name suggests, covert cameras are designed to seamlessly blend into its environment. Thus, onlookers are unaware of its presence while it continually captures their facial details and their actions. These cameras are ideal for monitoring customers in areas of a store that are unseen by wall or ceiling security cameras.
  • PTZ Dome Network Cameras – PTZ dome network cameras are designed to discreetly monitor a wide angle area. These cameras are housed in a dome, thus onlookers are unaware if the camera is pointing at them or not. The camera operator may manually tilt, zoom and pan while capturing high-quality video. Features typically found in these cameras include EIS, or electronic image stabilization, auto tracking and auto camera flip.
  • Fixed Dome Network Cameras – Like its name suggests, a fixed dome network camera does not offer lens movement. Rather, it is a fixed camera housed in a dome. The primary benefit of this camera design is its discreet design; however, the main drawback is its inability to interchange its lens. However, many fixed dome cameras offer a varifocal lens, which allows the field of view to be manually changed by an operator.
  • Fixed Network Camera – This camera design is perhaps the most common. Implemented to be visible to onlookers, a fixed camera cannot pan or rotate as its field of view is static. However, many fixed network cameras allow operators to change its lens. For example, a single fixed camera may be adjusted to house a wide-angle, telephoto or normal lens. Some camera designs are outfitted with a varifocal lens to adjust its field of view.

 

As stated earlier, these are simply the most common foundational designs. Each of the aforementioned is available in a wide array of configurations. To determine the best network security camera for your property, research available options and features. Remember, every property features unique monitoring challenges and the goal of a security camera system is to overcome these challenges for adequate monitoring.

Analog Resolution vs. Network Camera Resolution

Many property owners who are interested in security camera systems desire to have cameras with high video resolutions. The reason behind this is the higher the resolution the better the image quality. Cameras with low screen resolutions may capture the happenings of an area, yet if the images are blurry or fuzzy, these cameras do little to actually assist law enforcement in the apprehension of a criminal. Within the realm of security cameras, a major question is, “What is the resolution difference between traditional analog cameras and network cameras?” The recordable resolution of security cameras is dependent on the restrictions of the actual recording device such as a DVR for analog cameras or NVR for network cameras. With analog cameras, the DVR is restricted to a maximum resolution of 720 x 480 pixels. However, network cameras offer a wide array of resolutions. For example, many NVR programs support 5 megapixel, or higher, screen resolutions. This results in a video resolution of 2,592 x 1,944 pixels. Therefore, if image quality is paramount in your decision making process, network security cameras are your only option. Review various NVR programs, as some software programs may feature resolution limitations.

Benefits and Drawbacks of Network Security Cameras

As with any other form of security cameras, network security cameras feature benefits and drawbacks. Before making a purchasing decision, it is imperative you review the benefits and drawbacks to determine if the financial commitment of network cameras is worth the benefits you’ll receive.

Benefits

  • Installation Flexibility – Perhaps the most notable benefit of network cameras is its installation flexibility. Unlike analog security cameras, network cameras are able to be installed anywhere on a property where there is an IP network. This is not limited to Ethernet cable only networks. Many network cameras are able to operate and transmit signals through a wireless Internet signal.
  • Encryption – Securing the images of a camera is just as important as having a security system in your business or home. Network security cameras offer two layers of data safeguarding. Firstly, video images are encrypted before ever being transmitted to the NVR. Secondly, videos are automatically encrypted and authenticated through encryption languages such as WEP, AES, WPA and TKIP.
  • Video Resolution – As discussed earlier, network cameras offer significantly higher video resolution when compared to analog cameras. This increase in resolution provides clearer videos capable of identifying facial features and car license plates.
  • PoE Connectivity – Network security cameras do not need to be plugged directly into a power source. Rather, these cameras may operate by connecting the camera to a PoE, or Power over Ethernet, protocol. This system powers the cameras trough the Ethernet cable instead of through a traditional power source.

Disadvantages

  • Cost – If cost is an issue, then network security cameras may not be the ideal surveillance solution for you. Typically, network cameras require a higher upfront cost than analog security cameras. However, this disadvantage may quickly disappear as the use of network cameras increases. The increase in demand will likely lower the cost of these camera systems.
  • Video Interception – Although not very common, video signals may be intercepted if network cameras are connected through an unsecured wireless network. This raises the security threat as criminals could potentially access video streams and monitor the security environment of a business or home. This undermines the effectiveness of the cameras and actually facilitates a crime. Avoid this scenario by never connecting network cameras through a public, or unsecured, wireless signal.

While it may seem that the benefits of network security cameras far outweigh its drawbacks, it is important potential buyers seriously weight both the pros and cons before making a decision.
