Megapixel VS HD-SDI

What is the difference between Megapixel and HD-SDI Security Camera Systems? We get many calls on a daily basis with customers asking whether or not they should choose one over the other. There are good and bad things about both. You should be aware that even though both systems can record at megapixel resolution, there are vast differences about both systems that you may want to consider before making your choice.

You will find many different debates between both surveillance systems. The easiest way to choose which system is best for your application is to take a look at these differences below:

  1. Megapixel cameras are capable of recording on their own. They generally have all of the same features that you would find in the rest of our Digital Video Recorders (DVR’s) and Network Video Recorders (NVR’s). You will be able to set up one IP camera on its own, or set up a few of them without ever needing an NVR to record its footage. A lot of megapixel IP cameras these days have the ability to record onto a micro SD card. It will save you some money if you’re looking to set up a surveillance system on a budget. However, you’ll ask yourself, so why would anyone ever need an NVR? That’s because in some application, you’ll need more storage space. If you set up the cameras on their own, you’re going to be limited to the amount you can record on a micro SD card. In turn, you’ll only have the capabilities to go back and view a couple of days of recorded footage as opposed to a couple of months. Also, NVR’s are generally going to act as a central hub for all of the cameras where recording each one on their own will make it harder for you if you’re looking to view all of the cameras at once. With an HD-SDI system, you’ll only be able to record the cameras if you’re using some sort of digital recording software or hardware.
  2. With an HD-SDI surveillance system, you’re going to need to have all HD-SDI technology. Unfortunately, you will not be able to use your current DVR with HD-SDI cameras. They transmit a different signal through the wires.
  3. Even though you may not be able to use your current DVR you will be able to keep your analog system wiring. This is a huge benefit for anyone who cannot re-wire their home or business. There are some situations where wires have been installed during the construction of a building and running new lines are near impossible without doing damage to the structure. In this case, it would be best to leave the wiring alone and upgrade your analog security system to an HD-SDI DVR and set of cameras. You’ll then be able to get the benefit of recording at megapixel resolution instead of being limited to D1.
  4. Even though it’s usually not really noticeable, megapixel systems have a bit of latency. Latency is also known as lag. If you’re viewing your video in real time, you may have a situation where you need to view the video exactly as its happening. Depending on how the network is set up, you may have a bit of latency (sometimes one second or more) and having an HD-SDI system will usually solve this issue when directly connected. You are then bypassing any network issues and recording the signal directly to and from the system without the inconsistencies of data packets being delayed.
  5. Many people purchasing a new system have a limited budget to purchase their security system with. HD-SDI generally ends up costing more money than a megapixel IP system. The chip needed to process the video in an HD-SDI system is generally more expensive than the ones manufactured for megapixel. Price has dropped considerably in the past few years and megapixel systems have become way more affordable these days in comparison to the costs of HD-SDI hardware.
  6. Even though an HD-SDI system is a bit more costly for the hardware, at the end of the day you may end up spending less because of ease of use. With a megapixel system, you may be stuck hiring someone with more of a technical background to set up your network and make sure that all of the cameras are connected correctly. Megapixel cameras each have an IP address and they all need to be set up correctly onto your NVR in order to begin recording each camera. You will end up having to choose between directly powering your cameras with a power supply or whether you want to use Power over Ethernet (POE) to power each IP camera. If you choose POE, you’ll have the benefit of just running one Ethernet cable for each camera all back to a POE switch, and then from there back to the NVR. This is where things can get confusing for most people who don’t deal with this type of network setup on a regular basis. Once you factor the cost of hiring a network technician, you may end up spending more money. However, with an HD-SDI system, every component is basically plug and play. You won’t need to worry about setting up each camera individually and at that point, running the wires will be your most difficult task.
  7.  One last thing you’ll need to consider is the reliability of your new surveillance system. If you ever have your DVR or Hard Drives fail on your HD-SDI DVR, your whole system will go down. You will no longer be able to record anything that’s happening on your property. However, if you’re using an NVR for your megapixel system and it crashes, at least you’ll have the peace of mind that you’re cameras are still capable of recording everything that’s happening for the next couple to few days depending on what type of memory card you have installed in each camera.

It seems that there are quite a few things to consider when trying to decide on HD-SDI VS Megapixel. If you think about it, it’s really not that hard of a decision to make. Personally, I would choose a megapixel IP system over an HD-SDI. It looks like the future is pointing to megapixel over HD-SDI because of all the added benefits between costs to reliability. Please keep in mind that HD-SDI still has its uses though. There are definitely some instances where it will be a benefit over a Megapixel IP system.

home cctv security camera

Installing home security has been seen as an important field of action that uses technology to provide protection around a person’s home, while being controlled from tech support. These surveillance systems allow you to monitor your home and provide a safe environment for you and your family by using web browser on a computer or even a smart phone. The following is a brief listing of new ways that you are able to keep your home well guarded from different types of intruders.

There are many essential parts in a surveillance system. Some of theses include surveillance cameras, a DVR (digital video recorder), power supply, cables, and a monitor. The cameras are used to film areas that are under surveillance; however, the DVR is used to record footage and display live scenes through the monitor. The power supply, which is used to power the entire system, is connected to the digital video recorder. It is also possible to run the DVR through a power box and then connect the power supply to the box. There are many things that should be put in consideration when installing a surveillance system. However, one of the most important things someone should consider is the type of cameras that should be used.
If you are considering installing a video surveillance around your home, you should learn about the different types of cameras that would best fit any reason or situation you may have for possessing a surveillance system. There are a couple of features to consider when it comes to choosing from the variety of cameras for a surveillance system. The three main cameras choices that are most commonly selected include: dome cameras, bullet cameras, and box cameras. Dome cameras have low visibility, meaning they blend in well with their surroundings, and are always attached to ceilings. Bullet cameras are prominent and are obvious in their appearance as surveillance cameras.

After selecting which the appropriate type of camera, the next step is to choose where the cameras will be installed. Out door cameras would be in necessity of weather protection, but it is also possible to purchase waterproof surveillance cameras or protective camera housing. In indoor installation, cameras must be placed where they cannot be seen by other but still allow coverage of the area that needs watch. Bullet cameras are usually placed in corners of walls while dome cameras are less likely to be seen. After determining the areas where the cameras will be placed, the following step in installation.

Installation can be a complex process. It is a difficult process from setting up the wiring to placing the surveillance cameras in their position and the connection of all the equipment from the installation. Where you place the camera is important. The distance of the camera to the area you are focusing on should be given careful consideration and make sure it is clearly visible. You must make sure the camera is properly mounted so it will not shake or distort the picture or image.

For those worried about security, out door camera are suitable because they are used to prevent criminals from attempted robbery and break-ins. If you would want to know what happens while you are away, these surveillances may ease your mind. Video surveillance allowed you to monitor or record in personal areas. For example, parents may want to watch over their children while they are sleeping and lower risks of danger or even to catch a crime in your own front yard.

But before you install a security system in your home, you should be aware of the legal restrictions on video surveillance. If you are not aware of these legal aspects, you may potentially face charges. Knowing the laws of having a security system will lead us to finally installing the surveillance system.

It is important that the installation of the surveillance cameras is done properly. Poor installation will not get provide proper results you’ve hoped for. Some surveillance has motion detectors that activate once the gadget picks up any movement within the area.

Home security systems may be very complex and installation involves mounting. The alarm system is called a close circuit system. When doors or windows open, they trigger sound circuits because when closed wires are in wiring loops, opening breaks that loop causing those unsatisfying noises. Installing this means installing the sounder first. This alarm is used to scare away any intruder or to call attention for help. You must be sure that the mount is correctly mounted. We must know how to wire the system after mounting the alarm and installing the switches, fire sensors, and window foils. A knife or wire stripper is used to cut off ¾ of an inch of the wire ends. Then loop each wire under a different terminal screw on the switch. Run the wire to every entry detection switches and sensors. Then add the copper wires to the screws and twist together two silver wires. They should go in the sensors without breaks or interruptions.
To connect the sounder, use solder less connectors to join black wire from the battery to the sounder to make it operate correctly. Then connect the wire ends from the switch to smaller wires on the sounder. Test sounder after by opening the door or window. If it is correctly installed, the alarms should go off. Besides alarms, there are many more gadgets for security for your front door. For example, push-button locks allow you to lock and unlock using the Internet or a smart phone.

When installing the indoor cameras, you must follow the manufacturers. Bullet cameras generally need screws to be able to be hung on the wall, it is that simple. One the other hand, dome cameras require a perfectly cut circle from the ceiling where the camera is going to be placed. These systems involve whole home wiring. Video surveillance and 24/7 monitoring that carry many features.

Installing home security system helps raise awareness about your home’s security and often leads to people being able to lower the risk of a home break-in. It also teaches families about security and how to take control of the home environment.

Man Watching Security SystemSo you got yourself a Security Camera System and you have your DVR setup either in your bedroom or in the garage and every time you have company or hear a noise outside your home you have to pull out that mobile device and run an application or go where your DVR is located to view those cameras, Here is the solution to that problem so you can view these cameras in all your TV’s just by going to a specific channel on any TV in your home, now you aren’t going to have the ability to change any settings but having the image in all your TV’s gives you peace of mind and it’s a simple shortcut that saves time since you aren’t going to have access to your mobile phone at all times or have the ability to go to the DVR’s monitor. You can also view it in your kitchen while you are cooking as long as the TV is connected to the same system either on a satellite system or a cable system.

What you will need

Satellite TV System

  • Perfect Vision PVDP2 Diplexer Dual Satellite Dish TV Antenna Combiner (PVDP2) Note* Any Satellite Diplexer should work, Perfect Vision Diplexer is prefered
  • Any RF Modulator
  • BNC to Video connector

Cable TV System

  • Any RF Modulator
  • BNC to Video connector

Adapter (Optional)

  • “Y” RCA Splitter / Adapter RCA Splitter

Quick links:
Systems:

Setting up your Satellite TV System

Note* this is for Dish Network System. Some Satellite systems have a switch that has an Antenna input if you are able to provide power and install the RF modulator in a weatherproof box you can do so without the need to add 2x Diplexers for each TV. Consult with your system manual. Illustration 6 shows this type of connection.

Sample system is a Dish Network System (Dual Tuner receiver with agile modulated output) Notice this system serves 2 TV’s.

Back of Dish Network Receiver

Connections:

Find the lines that come from the LNB to the satellite receiver. NOTE* many of these have a switch connected from the Dish LNB that goes to all the splitters or diplexers .

Tap into the line that goes from the Satellite Switch in this case a Dp Plus 44 Switch see Illustration 1, without the Dp Switch see Illustration 2, it is the purple line marked SAT. Connect the sat cable “purple line in illustration” into line in, then the other side of this cable connect the line into the sat in/out. Make sure these connections are like the ones in illustration 3, there is a current going through this line and it could backfeed into the RF Modulator causing it to malfunction or in worst case scenario rendering the RF Modulator useless as it would burn up the internal components.

Illustration 1: With a DP Switch

Illustration 3: Rf Modulator to Diplexer

RF Modulator to Diplexer

Illustration 3 shows the connection required from the RF Modulator to the diplexer which is injecting an RF Signal to the existing line.

Setting up your Adapter

Adapter is optional and it will only work in single channel mode, meaning one channel has to be in full screen for that one channel Adapter to work unless the Adapter is tapped from the microphone to the DVR using a ”Y” splitter Adapter cable. No Adapter connection is needed at the receiver end since it will be added to the RF Signal . See Illustration 4 for the cable needed.

Illustration 4

audio adapter

Illustration 5

connections to dish receiver

Connecting the Satellite Receiver is very simple, on Illustration 5 connect SAT Cable from the first diplexer we already installed to the top in/out ‘A” on the diplexer after that connection is made connect the antenna to the TV in/out on the diplexer “C” and finally connect “B” Sat in/out to the Sat in on the Satellite receiver.

Once you have done this you are done when it comes to making all connections the rest is done via the on screen settings in your receiver.

Searching for your local channels after the connections are made

Power up your Satellite Receiver and go to the Menu by pressing the menu button in your remote then select option 6 which is “System Setup” , go to option 8 “local Channels” on the new window select local channels , select “Scan Locals” your receiver will now scan your local channels , the local channels that the receiver found will not be displayed on the left of the screen. You can highlight each channels to see the channel strength after that you can hit “DONE”, then you can press “CANCEL” twice to exit the menu, finally go into your guide and search the channel that the RF Modulator is on, Channel 65 or a channel that is not being used by any station is required since those channels will cause interference.

Once you have selected the channel in your RF Modulator and tuned into the same channel in your TV you should see all your cameras in that channel as well as Adapter only if you have installed the optional Adapter splitter or selected the Adapter out from your DVR.

*Illustration 6: Satellite Switch with Antenna in

Satellite Switch with Antenna in

Setting up your Cable TV System

Setting up your Cable TV system is much easier than setting up a satellite system with your DVR and RF Modulator.

The system we will be installing this RF Modulator will be a Comcast system with internet.

Marijuana Cultivation and Camera Systems – i-502 Compliancy

Written By:

marijuana cultivation

You are probably asking yourself, how do these go together?  The reason being is that most people hear of someone growing marijuana and they think illegal drug dealer, not profitable business.  For the last several decades you were right, but times have changed and so has the industry.  In recent years there has been some dramatic changes in the perception and regulation of marijuana, whether it be for medical marijuana or recreational use marijuana.  In recent years more and more citizens have voted to allow for the use of marijuana in different ways.  As the laws have changed so has the regulations for this industry.

 

One state in recent months that has legalized the recreational use of marijuana has been the state of Washington.  With the legalization of use, also came the legalization of cultivation.  With the cultivation lawmakers have put in place a series of requirements that growers and sellers have to follow in order to be in compliance with state laws.  The following information comes from Washington State Liquor Control Board’s i-502 compliancy.

 

(2) Alarm systems. At a minimum, each licensed premises must have a security alarm system on all perimeter entry points and perimeter windows. Motion detectors, pressure switches, duress, panic, and hold-up alarms may also be utilized.

(3) Surveillance system. At a minimum, a complete video surveillance with minimum camera resolution of 640×470 pixel and must be internet protocol (IP) compatible and recording system for controlled areas within the licensed premises and entire perimeter fencing and gates enclosing an outdoor grow operation, to ensure control of the area. The requirements include image acquisition, video recording, management and monitoring hardware and support systems. All recorded images must clearly and accurately display the time and date. Time is to be measured in accordance with the U.S. National Institute Standards and Technology standards.

(a) All controlled access areas, security rooms/areas and all points of ingress/egress to limited access areas, all points of ingress/egress to the exterior of the licensed premises, and all point-of-sale (POS) areas must have fixed camera coverage capable of identifying activity occurring within a minimum of twenty feet of all entry and exit points.

(b) Camera placement shall allow for the clear and certain identification of any individual on the licensed premises.

(c) All entrances and exits to the facility shall be recorded from both indoor and outdoor vantage points, and capable of clearly identifying any activities occurring within the facility or within the grow rooms in low light conditions. The surveillance system storage device must be secured on-site in a lock box, cabinet, closet, or secured in another manner to protect from employee tampering or criminal theft.

(d) All perimeter fencing and gates enclosing an outdoor grow operation must have full video surveillance capable of clearly identifying any activities occurring within twenty feet of the exterior of the perimeter. Any gate or other entry point that is part of the enclosure for an outdoor growing operation must have fixed camera coverage capable of identifying activity occurring within a minimum of twenty feet of the exterior, twenty-four hours a day. A motion detection lighting system may be employed to illuminate the gate area in low light conditions.

(e) Areas where marijuana is grown, cured or manufactured including destroying waste, shall have a camera placement in the room facing the primary entry door, and in adequate fixed positions, at a height which will provide a clear, unobstructed view of the regular activity without a sight blockage from lighting hoods, fixtures, or other equipment, allowing for the clear and certain identification of persons and activities at all times.

(f) All marijuana or marijuana-infused products that are intended to be removed or transported from marijuana producer to marijuana processor and/or marijuana processor to marijuana retailer shall be staged in an area known as the “quarantine” location for a minimum of twenty-four hours. Transport manifest with product information and weights must be affixed to the product. At no time during the quarantine period can the product be handled or moved under any circumstances and is subject to auditing by the liquor control board or designees.

(g) All camera recordings must be continuously recorded twenty-four hours a day. All surveillance recordings must be kept for a minimum of forty-five days on the licensee’s recording device. All videos are subject to inspection by any liquor control board employee or law enforcement officer, and must be copied and provided to the board or law enforcement officer upon request.

 

Alright, now that you see the law lets talk about the systems that will meet these requirements to keep your location in compliance.  Based on the bare minimum requirements, any of Techpro Security DVRs or NVRs will work.  To meet the absolute requirement of 640×470 pixels will put you into any DVR that can record in D1 resolution (704×480).  Since there are no required minimum frames per second stated, you can get away with a Techpro Security Mini Economy DVR .  This unit will record D1 resolution and 7fps (frames per second) on all channels.  It is also accessible for remote viewing, which makes it meet the requirement of IP internet protocol of the recorder.  Based on the 45 days that is being required to be stored and recording 16 cameras at D1 resolution and 7fps, you will need a minimum of a 3TB hard drive.  You can calculate a rough idea of the amount of hard drive space you will need with Security Camera King’s Hard Drive Calculator.  If it was my operation, I would want to have more than the “bare requirements”.   I would do a Techpro Security Ultimate Series DVR ,  the problem with only using the mini is that to record 16 cameras at D1 resolution and 30fps you will need 10TB of hard drive space, and the mini unit will only hold up to 6TBs of hard drive.  I would step up to the Ultimate Full Size, with this unit you can put in up to 8 hard drives or a total of 24TBs of space.  You will also want to upgrade the cameras from a basic OD-CM600IR50-B camera to a minimum of the OD-LX700IR50-W.  Although the basic camera meets the requirements of the law, I am not a “bare requirements” type of person.   Based on the fact that marijuana plants are very sensitive to light, I would shy away from using any camera with greater than a 50 IR distance in any area where growing occurs.  Otherwise you could turn your plants unusable from too much stress.

 

Now if this was my business and my livelihood, I would go all out to protect my investment.   I would use a Techpro Security NVR and Techpro Security IP Cameras.  The reason I would go this route is that the resolution on these cameras are at a minimum of 720p and go up to 1080p.  I don’t know about you, but I want to know exactly what is going on with my investment and know if anything ever happened I would be able to catch the perpetrators.   If I was looking for a system already put together for me I would go with Security Camera Kings pre-built Complete 16 Camera Elite Series NVR Security Camera Surveillance System.  With this configuration you will need to have at least 15TB of hard drive space to stay in compliance.  I would personally put in 18TB to slightly exceed the minimum, because the last thing that I would want to have happen is be even a couple hours short of the 45 day requirement.   Now if I was trying to be a little more conservative on my spending, the next system I would go with would be an analog system with more cameras to give me over coverage, an example would be the COMPLETE 32 CHANNEL DVR ULTIMATE SECURITY CAMERA PACKAGE.  I would at a minimum upgrade the cameras to the OD-LX700IR50-W and add at least 19TB of HDD space.  Now if a pre-built package won’t work for you, there is a really cool option of creating a Custom Built Package, which offers the same discounted products but you can customize the equipment to meet your exact needs.

 

No matter what way you go, you can’t go wrong with a system from Security Camera King, even the base records will meet the requirements of the State of Washington Liquor Control Boards requirements.  The only thing you will want to make sure of is that whatever recorder you go with can hold enough hard drive space, so make sure to use the CCTV Hard Drive Calculator.  The last thing you want to do is fall short on this one requirement and either get fined or worse lose your license.  It has been way too long of a wait to be able to grow and cultivate marijuana.

Why Security Cameras Are the Best Business Investment You’ll Ever Make

business surveillance cameras

Starting a business is extremely difficult. You have an idea of a product, service, or delivering both in a new way. You have worked out how to execute the new business to be profitable. Either you or another 3rd party company has done the research to find your niche in the marketplace. Finding the best location for a business is critical in any business open to the public. It needs to be visible on a major road with easy access to get into and out of. Then getting the location renovated and redecorated to the theme of the new business all costs money and lots of it. Don’t forget about permits and licenses to operate, since the government always gets their cut. Now you have tools and inventory to purchase before opening the doors. Finding the right employees and training them takes more time and money. Up to this point you as the owner have a very large investment in your new baby, so can you really afford to take a lock and key approach to protecting your new business? I think not.

As a society we have many methods to protect our businesses. Law enforcement and threat of imprisonment has been the standard forever. As a prevention method they do not do well. In most instances law enforcement springs into action after something has already happened. That is too late for many people. In some cases if no one is there to see the crime committed it is difficult to even get an arrest. Then in many cases a criminal will get off on a technicality. A common technicality would be the accused having a “witness” seeing them elsewhere at the time of the crime. The prosecution can only attack credibility to try to sway opinion of the judge and jury. In a jury trial that has some affect. If the trial is only by judge facts are typically only considered and will be ruled on accordingly. If there is a lack of evidence getting a conviction will be next to impossible. If a picture is worth a 1000 words, a video is worth peace of mind.

Security cameras offer a level of protection that has not been available to the small business. Cameras have come a long way from ten years ago. It used to be the only way you could really identify a person was if you actually knew and saw that person on a regular basis. Now cameras have such a crisp picture that you can run them through facial recognition software and the police can identify the person. Being able to expand on the amount of TV lines in a camera has improved the resolution of the image. Another technology wide dynamic range (WDR) allows the CCTV camera to adjust to light conditions. Thereby allowing more light to enter the iris and delivering a crisper image. Backlight compensation adjusts to light that is behind an object being recorded so the object is illuminated instead of appearing dark. All recording devices are susceptible to interference or noise on the signal. Digital noise reduction (DNR) technology reduces scattered light and electromagnetic interference on the video feed. DNR filters out the external interference from other sources thereby improving overall picture quality. Vary-focal lenses create the zoom feature on cameras. With Vary-focal a camera can be used at greater distances to monitor an area of interest.

CCTV cameras are very good in doing the same thing as an armed guard. When in plain sight people know they are on camera. These people will think twice before acting unethically forcing them to take their criminal intentions elsewhere. The best part about cameras is they don’t need breaks. They do not go home at the end of the day. 24 hours a day they record what is happening. There is no bias in what is recorded ensuring no prejudice one way or the other. Just as guard on duty lets people know we are watching, you will be caught, and you will be turned into law enforcement. Security camera systems put the fear of being caught back in the front of people’s minds. Audio microphones are now available in addition to the cameras provide you the ability to listen in on anything that is happening inside your business. Just like the cameras they can be used almost anywhere. This takes you from the digital age to the age of knowledge.

These new technologies implemented in CCTV cameras give you the owner the ability to seek damages against unscrupulous customers and employees. The better images deliver undisputed proof of malicious actions. This data can be used with local law enforcement as evidence in court to recover losses. As much you want to believe you hired the right people bad apples always slip through, and will cause damage to your company instead of making it better. Solid video images give you the ability to take action for compensation from theft or intentional damage to your property. The audio feed can help add to the proof of intent to damage the company. Whereas before all you could do is question a person as to where or what happened to an item. Now you can say I have you on camera stealing from me. I have you on camera intentionally causing problems in my company. With video evidence the wrongs can be righted, and more importantly leaving no grey area to be questioned. The investigation is simplified to watching a video recording. In a few minutes a determination can be made and you can be confident you made the right choice.

The steps you take to protect your company are as important as the services and products you provide. There are people that have made it their business to steal from others to make money. It is on you to let your customers and employees know that theft and damage to company property will not be tolerated, and has repercussions. CCTV cameras let those individuals know that you are serious in protecting your investment.
