Security Camera Question?




John


Hey all. I'm looking for a wireless security camera, but not one just to monitor. Most cameras Im finding are for monitoring only. Where can I find a wireless camera that reads into your computer that records the video it takes. I looked up that x10 camera but Ive read very bad and some good reviews on it.

What do you guys think...
Thanks,
John



Answer
I have not done much with surveillance cameras lately, but not so long ago I was very much involved with a team that developed artificial intelligence computer software to assist with monitoring them. None of the cameras I worked with were wireless -- they were all fiber optic or coax.

In my development lab, we used a variety of cameras with a variety of different lenses. The fixed cameras were cheapest while the pan-tilt-zoom cameras were significantly more. That being said, some of the lenses we used with fixed cameras could exceed the price of some PTZ units.

The solutions available depend on what your budget is.

I will assume that you are interested in hobby solution, but will check back later to see if you have provided additional details.

For a hobby solution, you can buy a wireless webcam. The webcam will communicate with your home router/access point. Once it hits the router, you can route the video data wherever you want. The software that monitors your camera is the key to recording or monitoring. Once you find a software you like that is compatible with your camera protocol, you just set it up to record as desired. Of course this means your computer needs to be on whenever it should be recording and you don't want the power to go out for any component involved (your camera, computer, or router) without a backup supply.

Hope this helps.

Answer
Nathan that is the worst advice I have heard if you don't know about CCTV products please do not post and mislead people tigger direct sell complete junk.

Not all CCTV equipment is created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of CCTV you can find the equivalent of a $2,000 golf cart and a $350,000 Ferrari and everything in between. Both have 4 wheels but that's where the similarities end, itâs under the hood that counts.

Just like any other consumer electronic in the end you get what you pay for. Most retailers and sellers make about a 40-80% profit margin, this is after costs like shipping and overhead. That means when you buy a product that costs $100.00 the manufacturer usually has only spent $30 to build it which simply means itâs not a good product and will probably have a working life of about 2 months. There is a reason these products are 1/10 of the price of good and reliable DVR brand names. The type of seller these products attract are online sellers (ebay) and will make profits margins as low as 2% which means they canât afford to offer good service or allow for RMAs (returns). Cheap products are like disposable razors they are NOT designed to last for a long time and you will end up replacing them every 2 months.

Now some products can be made cheaply like ipod cases, screen protectors, and other simple products with no moving parts or electronics. DVRs need to be good quality as they run 24/7 (20X more than the average electronic device) and process anywhere from 30-480 frames per second which in a year is over 15 billion images, and a good DVR should last 3-5 years.

A true DVR and camera require 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 and are one of the few products that canât be made both well and cheaply. Cheap and inexpensive products like Q-see, X10, Swan, Lorex, and other low grade DVRâs and cameras sold by Tiger Direct, Newegg, radio shack Sams Club, are not used by any security professional and should only be used by hobbyists.

To be honest Swan sells complete Garbage and is not used by anyone who has worked with CCTV or security products. I know other manufactures who used the same product as them and they felt they wee such poor quality they offered money back and replaced them at there cost. They are poor quality especially for IR cameras, due to low quality material, low S/N ratio, and c grade CCD image chips.

If you are only going to spend 70$ on cameras then you should buy 15 dummy cameras they will be just as effective and cheaper hen swan cameras.


Also as far as night vision or IR cameras go most do not give good images in the dark. Many companies claim good night vision but there are only a handful of brands who give night vision over 30 feet out doors. normally if a cameras is rated 150 feet of IR it will give you ok images at 30 feet at night and good images at about 20 if rated for 60 feet you might get 15 indoors and will be useless outdoors.

Some good CCTV brands that I recommend are Bosch, Pelco, Honeywell and Ascendent.

Economical DVR's
Two good economical DVRs I would recommend are Ascendent's AVP-4120 DVR or Pelco's DX-400. They will allow you to view all your cameras instantly from anywhere in the world using either IE, or a client software. The AVP-4120 uses the latest H.264 codec to improve streaming and recording time, and will allow PCs and Apple computers to remotely view cameras. These are the DVRs I would recommend that are good quality and affordable from companies who stand behind there products.

Again if you are going to buy Swan products save money and get dummy cameras they are just as affective and you will be less disappointed.

I happen to know Ascendent is offering a special on a 4CH DVR and 4 cameras 2 of them are IR. http://dealer.ascendentgroup.com//cctvpaâ¦
