Question about home security camera systems?
I want to install wireless security cameras for my home. How does it work? I assume the cameras feed information to some sort of receiver, but must the receiver be hooked up to the TV?
I would like to view all the cameras on any TV in my house. I would like to view it on my phone or work computer. I would like to be able to record and save the footage for at least a day before deleting it.
What would I need to view it on each TV in my house?
Can I view it on each TV without a wire connecting to every TV? What would I need?
With the interest of conserving hard drive space, could I set the camera to record only if an image comes into view? Are wireless cameras reliable?
I appreciate any help but keep in mind I may need things explained in beginner terms. I am not very tech savvy.
Hello
95% of all wireless cameras are compete junk and any wireless camera under $400 run on 1.2 or 2.4GHZ or 5.8ghz and don’t offer encryption. This is bad for 2 reasons one the signal can easy be jammed, with a laptop you can actually hacked video feeds so a criminal can use it to spy and know a good time to target your business or home.
Now one option for wireless is using commercial IP radios which are basically wireless routers on steroids and can offer distances up to 40km of wireless with military encryption, this is not a cheap solution but neither is digging a trench. using these radios not only give you a security infrastructure but also communications infrastructures as well for internet and other purposes (LAN network)

Not all DVRs are created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of DVRs you can find the equivalent of a $10,000 Kia and a $350,000 Ferrari and everything in between. Both have 4 wheels and windshield but that where the similarities end, it’s under the hood that counts. Just like any other consumer electronic in the end you get what you pay for.
I suggest you buy a PC based DVR has they have more processing power and normally have a much smaller file size and offer more features then Standalone DVR’s. I know many people buy a cheap standalone DVR, only to upgrade to a PC based in 6 months especially when they are using it to manage a store remotely. Also PC based allows you to record up to 64 cameras where a standalone will have a limit of 16.
Many people have the misconception that a PC-Based DVR is simply an off-the-shelf PC with video capture (encoder) cards, display (decoder) cards and some generic OEM software. A true DVR requires years of research and development to facilitate the seamless integration of both the hardware and software. DVRs are highly complex systems that must run 24/7, processing millions of images per day. This makes consumer-level hardware inadequate for DVRs which is why Ascendent uses custom-built PCs with performance-level hardware.
My personal favorite DVR is Ascendent X4 series: Ascendent’s Tri-Fusion Hybrid Platform allows for the creation of a true hybrid surveillance system by utilizing the advantages of Analog, Megapixel, and IP technologies for unparalleled customization and expandability. I am working on government projects and use Ascendent cameras and DVR because the offer superior performance and cost less then comparable brands like bosh, Honeywell and pelco.
The X4 also uses the latest H.264/SVC codec offer video substantially better quality,. While its file size sizes is 30% smaller than MPEG-4, 60% smaller than MPEG-2, and exponentially smaller than MJPEG.
File size is crucial to streaming because most DVR’s on the market record at real time performance (30FPS per channel) so on a 4CH is trying to send 120, 8CH 240, and a 16CH 480 images per second which requires way too much bandwidth even for the most extreme internet connections.
The smaller the files size the more images are able to be sent, and the faster they can be processed improving both FPS and speed. File size is the heart of any DVR and goes far beyond just its streaming capabilities, as it also determines the recording storage time, how much you can back up at once, how fast it renders and searches video. The file size of a DVR impacts the performance of the DVR in just about every aspect from speed to longevity and is often the most important spec of any DVR.
If you are buying a DVR and streaming is a high priority I suggest you ask for a demo and connect to the DVR to make sure it is able to stream fast enough for your needs. Most DVRs say they have remote viewing but it is often too slow and laggy to be of any use especially if it is a standalone. Some good DVR brands that I recommend are Bosch, Pelco, Honeywell and Ascendent. These brands are what security professionals use, Q-see, Swan and Lorex are only used in residential applications because they are sold by Tiger Direct, Spytown, Newegg, Sams Club, Costco and other retail outlets but are not used by any security professionals also their tech support rarely speaks English as their first language…
These brand manufacturers also have a complete line of CCTV cameras for any application from residential to military.

I have done projects that required cameras to stream over satellite and cellular networks and the only DVR that could provide the video streaming was Ascendent Technology Group’s X3 DVR. To give you an example of what a good DVR should stream like, below are instructions on how to connect to Ascendent’s X3 DVR using Internet Explorer.
If you are on a budget I would suggest the aVP-4120USB it will allow you to remotely view your ca
