QandA1

Learning about our DVR’s can help you better understand them and allow you to do the more advanced functions, but first you need to learn the basics. Not just the basics but also things that can make setting up the DVR an easier process. This article will go through basic functions like creating a new user and adding an IP camera, to more advanced functions like changing the IP of a camera and enabling tour. This article can be very useful for CCTV Dealers, Installers, and the average consumer. It helps explain simple tasks that you could only learn by digging through the User Manual or through experience of using the device.

1. Why does a DVR beep when I turn it on and how to make it stop?

The DVR has a built in speaker that emits a sound when there is an error or when it does a simple start-up. Every DVR emits a single beep when the unit does a complete start-up test and the single beep is the DVR’s way of sayings that is ready to go. There is no way of turning that sound off. Now when there is no Hard Drive or when the Hard Drive gives you an error of some sort, the DVR will start with the single beep and then also emit a short and long beep. If you want the sound to stop then you need to either press the power button 3 times or navigate trough the settings to release the alarm for the start up or turn the alarm off completely for future start-ups. To adjust it through the settings you need to go to Menu>Advanced>HDD Setting, and then hit Alarm Release; this will shut the alarm off until you restart. To shut the alarm off completely you need to go to Menu> Advanced>Abnormality, and choose to shut off alarm when there is no Hard Drive. In this menu you can also shut off other alarms.

2. How to change the IP address of a DVR/NVR and an IP Camera

Using Ethernet cables an IP Address (Internet Protocol) are how devices communicate over a network; All of our DVR/NVR’s and IP cameras work the same. Most of our IP cameras and DVR/NVR’s by default have an assigned static IP address but to use more than one device on the same network you need to adjust the IP address for each camera. To change the IP of a DVR (from the DVR) you have to go to the Main Menu>Settings, and Network. From here you can change the IP address of the Unit and specify what ports you want to use to remote in from outside the network. When choosing an IP address make sure you put the correct Subnet and Gateway. Also make sure the correct IP scheme is used for your network (192.168.1.x or 10.0.1.x). To adjust the IP of a camera you can use the Configuration tool that is provided in the CD that comes with the camera. Start the config tool and hit the refresh button to search for the camera (the default address is usually 192.168.1.108). Once found double click it and log in using the default password “admin”. You can quickly change the IP of the camera and continue to do it for every camera you add on. Just make sure you only plug one camera in at a time or you will get a IP conflict.

3. How to change the resolution of the Camera

There are many different cameras that we sell that work at different resolutions. Most of them you can adjust using your DVR but when it comes to IP, the camera does all of the work. To adjust the resolution of an analog camera you need to go to the DVR and navigate to Main Menu>Settings, and then encoding. In this menu you can not only change the resolution but also change the amount of frames, the bit rate, and change the extra stream. The reason for changing your resolution is because not all DVR’s can record at max resolution and a high frame rate. Most analog DVR’s tell you how many frames you can have per channel at max resolution. For example, out DVR-LT16480MHD can handle 16 cameras at 30 frames per second at D1 resolution and our DVR-EL16480ME can only handle 16 cameras at 7 frames per second at D1 resolution. With IP cameras the encoding is done in the camera and the NVR is just the storage. The NVR’s do have a max bandwidth they can receive so when connecting cameras to the NVR you have to do some calculations to figure out what resolution to set the camera to. You can set the resolution of the camera on though it’s own web service but for this article I will explain how to do it thought the NVR. Once you connect the camera to the NVR you can go to the Main Menu>Settings, and then Encode. From here you can adjust the resolution, frames per second, Bit Rate, and the Extra Stream for remote viewing. When calculating the resolution for all the cameras you connect to you NVR you also need to consider the Bit Rate. Doing so will help you apply more cameras to the NVR without taking to much from the picture.

This article was created to help people understand there DVR’s, NVR’s AND cameras better so you can do more with your system without having to search through the whole manual to find or call tech support and take more time out of your day. We sell our technology to help make your lives easier, not more confusing. This is the first of multiple FAQ articles that will help you understand the basics of your devices. If you have a more complex problem please call out tech support line for further explanation at 866-573-8878.

How to Connect Cameras to an NVR

Written By:

NVR

Here at Security Camera King we have a variety of surveillance products that can help protect a home or business from crime. The products range from DVRs and NVRs to all the connectors that are needed to connect the cameras to the systems. Setting up a surveillance system DVR, which includes Analog, HD-CVI, and HD-SDI, tends to be easier to put together. When it comes to NVRs, they are working through a network and can be difficult if you don’t know what your doing. The biggest tough spots for this system are when connecting the system to your network, connecting your cameras to your network, and adjusting the frames and resolution of all the cameras to manage bandwidth and NVR load. IP camera systems are very advanced systems and if done properly can give the highest resolution in the industry.

Setting up an NVR has many steps before it can function properly. First things first is running cable for where you want cameras. Next is mounting cameras on a building or anywhere needed. After you have all of that done you can now properly connect your NVR to your network. You need to power up the NVR with the provided power supply and attach any necessary cable such as mouse for controlling the NVR’s interface, Power cable for built-in POE, Monitor for viewing the NVR’s interface, and lastly an ethernet cable that leads back to your router or a switch connected to your network. Now depending on how you want to manage your camera whether you want it on its own network or connected to your existing one there are different ways of accomplishing your goal. Setting up the NVR for earthier style is the same you need to assign a static IP address to your NVR so that you access it locally and remotely. The way to do this is by going to the “Main Menu” on the NVR (When doing this you will be prompted for username and password which is “888888” for both), then you need to go to “Settings”, and; “Network”. This is where you enter the IP for the NVR. By default the IP should be “192.168.1.108” and the “DHCP” should be unchecked. Now you can enter an IP address, Subnet, and Gateway of your network so that it has it’s own individual address on your network. This is all you have to do to set your NVR to your network and the next step is to start connecting your cameras to your network.

With the cameras mounted and the cable running to the destination of your choice either by your NVR or a spot in the attic/roof where your switch will be you can now start connecting your cameras to your network. Before you just plug all the cameras in at once you need to know what you want to plug them into. If you are just plugging them all into the POE built-in to the NVR then you can just plug in the cameras one by one till they show up on the NVR’s interface. This is the easiest way to connect cameras because as you plug them in, the NVR self-assigns an IP address to each camera. (This is only possible with our NVR’s and the EL Model Camera). Also when connecting your cameras this way makes the cameras only manageable by the NVR. If you are connecting your cameras to a separate switch then it requires a little more work. You have to connect the cameras in one by one just like before but before you connect another one you have to change the address for the camera. You can do this 1 of 2 ways, you can change it thought the NVR (This is only possible with our NVR’s and the EL Model Camera) or you can change it on the web interface built into the camera. The easy way is to just change it with the NVR. The way to accomplish this is after the camera and the NVR are connected to the switch, you search for the camera in the “Remote Device” section from the “Main Menu” and click edit next to the camera on the network. (Default is 192.168.1.108). After that is complete just repeat with every camera you want to connect. You can also adjust your color settings in this menu so that you don’t have to login to each camera and set it to the way you want. This can come in handy when you have a lot of cameras to manage. This is the process to connect your cameras to an NVR.

Now that the cameras are connected you need to adjust some settings on them to achieve maximum power out of you NVR. All the NVRs we sell have a certain number of frames or max bandwidth that it can handle. It’s important you know what the amount is because not all of them are the same. Once you figured out what the limit is you can adjust your cameras. To do so you need to go to the “Main Menu” on the NVR, “Settings”, and “Encode”. Here you can select the camera you want and adjust the frames and the resolution you want it to record at. You may also want to adjust the “Bit Rate” but you need to know what your doing or you can diminish your video quality. To copy this to other cameras in your NVR just adjust one camera the way you want and then click “Copy” and choose which cameras you want to copy the settings to. Under the same “Settings” menu you can adjust the schedule of when your camera records and if you want it to record 24/7, motion, alarm, or all three.

Compared to DVR’s, NVR’s are more difficult to set up. Setting up the IP for the NVR so that the NVR can be accessed locally and remotely. Connecting all the cameras to the NVR one by one assigning IP address to each camera. Lastly adjusting the cameras and NVR to get the most performance out of your NVR’s. Knowing these steps will make it easier to add an NVR for your surveillance needs

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.

Internet Surveillance Cameras

Written By:
Thursday, September 15th, 2011

internet surveillance cameras Do you fear what is happening in your home when you are not there? For these homeowners, Internet security cameras offer much security. They are easy to install and offer great security. There are many options on the market today. New options are being developed each day. However, understanding the basics will allow you to make an informed decision on what is right for your home. Homeowners interested in installing an Internet security camera often become confused about the specifics that they need to look for. It really becomes an individual choice once the homeowner understands the basics.

Important Points to Remember When Purchasing an Internet Security Camera

Each Internet security camera system requires a network video recorder. This recorder acts as the brains of the Internet security camera system. It controls the configuration, it allows the user to playback the photos, it allows the user to expert the data for other users and it allows the Internet security cameras to connect with other Internet devices depending on the user’s direction.

Internet security cameras are a great asset in a home security system. It is, however, only as good as the monitoring that accompanies the system. Unless you are prepared to look at the feed 24 hours a day, 7 days a week, it may be wise to also hire a monitoring company. The monitoring company can alert emergency personnel when needed to your address.

Internet security cameras are either analog or PTZ. Users need to decide which is right for their individual circumstances. The main advantage of an analog camera is the cost. The main advantage of the PTZ system is that it can zoon in on user demand to get better photos. Whichever system is chosen, make sure that the camera will capture a 360 degree view and has the ability to track the main subject in a scene.

Look for an Internet security camera that will allow the user to install a large SD card. While the main recording is done in the network video recorder, the SD card can be an important back up system. The more memory the SD card has the more information that can be captured on it. If there is an interruption in the network, then the SD card will still capture the information should something occur. It is also important to also consider the amount of bandwidth the system will use and the cost of that bandwidth.

It is important to consider the power source when purchasing a camera. Internet security cameras require electricity. Think about this before you buy the camera as it may determine the type of camera that you ultimately purchase.
It is also important to consider the best color of camera to purchase. No one wants an ugly Internet security camera or cables. Both are available in a multitude of colors. Buying the right color will also help the camera and cables blend into the background.

Types of Internet Security Cameras

Internet security cameras come in several basic types. Each types has its own advantages and disadvantages.internet surveillance cameras
The first type of Internet security cameras are box cameras. These are the most popular option. They are used in many businesses and in some homes. They are usually rather large and may deter some crime by their mere presence. When purchasing a box Internet security camera it is very important to consider what type of lens is right in each circumstance. These cameras work best in circumstances where there is enough available light to take the photo. The box camera can be equipped with infrared lenses to take lights in low light circumstances. The box camera can also be installed in special housing to make it waterproof. Remember whatever type of box camera you choose that you install it so that it will cover the majority of the room. These cameras only take photos in one direction. It is important to keep this in mind when installing the camera and figuring out how to power the camera.

The second type of Internet security cameras are dome cameras. These cameras are more attractive to some homeowners because it is hard to tell exactly where the dome camera is taking the photos. These cameras are easy to install and waterproof dome cameras are available. Look for a dome camera with interchangeable lenses so that the homeowner can be assured of having the right lens should circumstances change. Like the box camera, these cameras are only capable of shooting in one direction. Expect to cover only about 25 percent of a room with a dome camera.

The third type of Internet security camera is the PTZ camera. These cameras are among the most flexible on the market today. PTZ cameras work best when mounted in open situations since PTZ cameras take 360 degree photos with a fisheye lens. These cameras take their name from the fact that they can be remotely panned, tilted and zoomed. This is a distinct advantage in monitored security systems where someone is actively watching the system all the time. These are the newest Internet security cameras and the quality continues to increase.

The fourth type of Internet security camera is the bullet camera. These cameras come in two different sizes. They are usually the least expensive option on the market. The homeowner gives up a clear photo in exchange for the cheaper price. These cameras are usually waterproof so they make a great option for outside use without modification. Most bullet cameras do not have interchangeable lenses so it is important to know where you are going to place the bullet camera before you buy it, so that you can buy a camera with the right focal length lens. It is nearly impossible to find support for these cameras. These cameras can only shoot in one direction, so make sure that you install the bullet camera in exactly the right place.

The fifth type of Internet security camera is the spy cameras. Basically, spy cameras rely on analog. It is possible to buy an Internet security camera that is hidden in a clock, pen or almost any other device. Make sure to check out the individual device as many manufacturers are trying to get too much technology into too small a package. The result is unclear photos or problems connecting to the Internet. Make sure to know the local laws where you intend to use these devices. Spy cameras can be hidden in clocks, pens and almost anything else. These cameras only take photos in one direction so strategic placement of the spy camera is mandatory. Look for a camera that will not make any noise and will work with the available light. These cameras are great for people who may need to move the camera around depending on different circumstances in the home. Most spy cameras are small enough to be carried with you on business trips or when someone else is using your car.

internet surveillance camerasBuying an Internet Security Camera by the Number

Regardless of the type of camera that one is considering purchasing, there are three factors that need to ultimately be considered.
The first of these considerations is the frame rate. It is often known as the FPS rate. This is the frames per second that the camera can be operated at. The top FPS is 30. The lower the FPS is the less fluid the pictures coming from the camera will be. A lower FPS will result in photos that are intermittent. If more than one camera is connected to the same network, the FPS for the entire system must be considered.

The second number that needs to be considered is the television line. This number is especially vital for analog cameras. The higher the number, the better the picture will be. The top television line number is 700. Look for numbers close to 700 to make sure to get crisp, clear photos.

The third number that needs to be considered is the megapixel number. Security cameras should have at least a 5 megapixel. Generally, the higher the megapixel, the lower the FPS number will be. It is a trade-off that must be carefully considered. Higher megapixels will allow the authorities to enlarge a single frame, while authorities can also learn much from watching the mannerisms in a moving film. Researchers are working at finding solutions that will allow cameras to have both higher megapixels and higher FPS.

Taking time to investigate all the options on the market is important before you buy. First, consider what you want the camera to accomplish. Consider how you will power the camera and associated equipment. Then, consider how the camera will blend into your existing décor. The next step is to consider the type of security camera that is right for your budget and your circumstances. Finally, look at the numbers. Consider the FPS, the television line and the megapixels. Understanding the basics will help you make the right decision to begin with. Each circumstance is different and there is no one right answer for everyone. Now that you are armed with the right information making an informed decision is easy. Visit Security Camera King’s inventory today to find the right Internet security camera for you.

DVR for IP Camera

Written By:
Wednesday, September 14th, 2011

When talking in security and surveillance camera system circles, you may have heard “DVR for IP Camera” mentioned.  That’s understandable because these systems are becoming very popular these days very fast.  In the following article will explain what all the abbreviations mean, how a typical system works verses a DVR for IP camera, and what an NVR is.

First, let’s talk about a non-IP or non Internet Protocol security camera system.  This system typically consists of digital video cameras (non-IP), a Digital Video Recorder or DVR, and one or more monitors.  In simple terms, the cameras are needed to capture the video image, the DVR records the images, and the monitor displays them.

A more “in-depth” view includes the following.  The camera lens gathers the light reflected off objects in its field of view and focuses that field of view on to a very small sensor chip (often 1/4 or 1/3 inch square).  There are actually two different types of sensor chips but only one is needed to do the job.  One type is called a Charged Coupled Device or CCD and the other is a Complementary Metal Oxide Semiconductor or CMOS.   Although they go about it somewhat differently, both chips yield the same end product:  They change the light energy from the lens into electronic impulses that can be used to create video images.

The camera translates the impulses into an electronic image and then digitizes it.  Ironically enough, a digital camera actually creates an analog image that must be converted to binary (digital) code before it leaves the camera.  It may also contain other specialized Integrated circuit chips that enhance the image and correct any flaws.  These special chips are called Digital Signal Processors or DSPs.

Once the signal is prepared to leave the camera it is sent along a co-axial video transmission cable such as RG-59 to the DVR.  Some systems are “wireless.”  Wireless systems include a camera with a built in transmitter and antenna.  Instead of sending the signal along a cable, the camera changes it into a radio signal that is sent to a corresponding receiver that is connected to the DVR.

Once the signal reaches the DVR, it is processed further.  A COmpression/DECompression or CODEC is employed to reduce the incredibly large size of the file without sacrificing a large amount of quality.  The DVR then stores the file on its Hard Disk Drive for later viewing or archiving purposes.  If a monitor is used, it also provides it with the finished signal.

In contrast, a DVR for IP camera system basically uses the Internet as the vehicle of transmission for the video image.  It may also send the image over cable directly to the DVR simultaneously.  The camera also has a built in web server and prepares the signal for both the Internet and the direct link to the DVR using one or more CODECs.  A popular method is to use the latest CODEC for streaming directly over the Internet, H.264, and for saving to the recorder MJPEG.

DVR for IP camera systems do not necessarily require a DVR to work.  The camera sends the signal over the Internet and the user/receiver uses a standard Internet browser to display the image.  If a recorded image is needed, the browser can save it to the personal computer on which the video image is being viewed.

The key advantage to using an IP camera over a non-IP camera is that cameras can be located thousands of miles apart and still be on a networked system.  As long as there is access to broadband Internet the IP camera can use the Internet as it would a transmission cable and pipe its data to just about anywhere.

Although the IP camera may be able to work alone, most systems will be of the DVR for IP camera type.  Before we end this article we should make it clear that when dealing with IP networking systems, the DVR is usually called a Network Video Recorder or NVR and it does operate a little differently than a DVR.

However, just the same, the NVR on a DVR for IP camera system is for storage of all the cameras’ video images and for central control of the system.

If you would like more information on a DVR for IP camera system, please contact one of our security experts as they will be glad to help.
