Here we have the lastest in internet protocol CCTV. It has been around readily available to the public for the last 6 year it was first released at 1.0MP & 2.0MP, only now have we invested into the product due to the problems it first had when it arrived to the market. " H.264 Blocking, Lagging In Live View & Recording, Latency" These were just a few problems it used to have but I can asure you now all them problems have been solved with the new 4.0MP IP.
So going on with 4.0MP IP CCTV the image resoultion is 2560 x 1440 pixels giving you a nice crisp 16:9 ratio so it will fit all normal widescreen monitors. The 4.0MP is twice the resolution of its older counter parts 2.0MP IP (1080p) which only will produce 1920 x 1080 pixels also four time the resoultion of the 1.0MP IP (720p) which only would produce 1280 x 720 pixels.
IP Cameras need to be wired in network cable by either using CAT5 or CAT6 cable with RJ45 crimps on the end of the cable, we rate running shorter runs of up to 70m on CAT5 cable and anything over 70m in CAT6. The maximum you can run IP camera cables is 100m with out putting a repeater inline. Regarding sending the cameras power and video signal it is sent down the same cable by something called PoE which is power over ethernet the maximum length it can be run is 100m like I said before but the way to get around this is, by using a repeater they are not any special device's it could just be a PoE Switch then it is able to run another 100m to the cameras.
There are a multiple ways that IP CCTV system can be wired in domestic and commercial premises. We have gone down the route of the None PoE NVR due to the versatility of the wiring. With using None PoE NVR'S you are not limited to running the cables from the NVR’S directly to the cameras like you are with PoE NVR’S you can run a single cable out to a area and then place PoE Switch there are then wire out to the cameras so making less work by not having run all the cables back to the NVR.
1) Very high resolution images.
2) True real time 25fps with very little latency. (AHD & TVI only 12.5fps)
3) Can be easily set up to be viewed over the internet or on a mobile device.
4) Fairly robust tried and tested technology which when purchased from a reputable supplier/manufacturer should give many years of reliable service.
5) I believe this technology will be around for a long time so service/repair will not be an issue.
6) Not prone to electrical interference like analogue CCTV formats.
