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¦

recomend security cameras?




bill


can you reccomend a good security system that will handle 3 cameras with motion detectors that can be viewed via remote access. please explain if possible.

thanks



Answer
Hello

Now when you ask for cameras with motion detector do you want them to be able to record only when there is motion, or do want them to have an actual motion detector inside of the,.

If you want them to be both a CCTV camera and a working motion detector I suggest Ascendents ASC-380PIR37.

link to the ASC-380PIR37
http://dealer.ascendentgroup.com//specialtycameras/31_1.html

If all you want is a camera that records when there is motion then all you need is CCTV cameras and a DVR. CCTV cameras put out 30FPS per second and send those images to a DVR it is then the dVR job to manage the video (decide when ans how to store the images, and allow you to remote connect to the cameras.)

the problem with viewing your cameras over the internet is most DVR file size is too large. File size is crucial to streaming because most DVRâs 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 to much bandwidth even for the most extreme internet connections.

also uses the latest H.264 codec becasue it offers better quality,. While its file size sizes is 30% smaller than MPEG-4, 60% smaller than MPEG-2, and exponentially smaller than MJPEG.

Not all DVR are created equal In fact, there are many options that offer varying performance much like the automobile industry. In the world of DVR's 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, itâs under the hood that counts. Just like any other consumer electronic in the end you get what you pay for.


If you are buying a DVR and streaming is a high priority I suggest get them to do a demo and connect to the DVR to make sure it is able to stream fast enough for your needs. Most DVR say they have Remote Viewing but it is often to slow and laggy to be of use. Some good DVR brands that I recommend are Bosch, Pelco, Honeywell and Ascendent.

Again I recommend going with a PC based DVR but if you don't want to spend the money I suggest Ascendent's AVP-4120 DVR or Pelco's DX-4000 as they will allow you to view all your cameras instantly from anywhere in the world using either IE. The AVP-4120 will also allow MAC platforms as well as PC to remotely view cameras and it uses the new H.264 codec but no standalone will offer the video streaming or performance a good PC based DVR will.

If you want to see how a good PC based DVR stream bellow are instructions on how to connect to Ascedent's X3L PC based DVR.

Instructions on how to connect to Ascendentâs DVR with Internet Explorer:

1) http://connect.ascendentgroup.com/ (Must be Internet explorer)
2) Install active X control
3) Hit âConnect)
4) DVR type PC
5) DVR code SITE-100
6) User ID Demo (case sensitive)
7) Password demo (lower case)
8) Hit extend config
9) IP address: 24.66.224.223
10) And hit connect

I hope this helps if yo have any other questions feel free to shoot me an email.
