I have a fairly large (for me) security camera system to install and the cost of cabling is keeping this project cost prohibitive. I'll outline what I'd like to do, and welcome comments on the feasibility.
I have 13 apartment buildings that need to have cameras mounted on the outside of them. Some buildings have 4 cameras, some have 3 and some 2. The office is about 700' from the furthest camera, and quite a few are over 500'. There are 31 cameras total, with more than 18 of them over 500' from the office. Running a single analog video/power cable to each camera requires a LOT of cable.
Here is what I'm looking at doing instead:
On each building, use IP based cameras, attach them to a small PoE network switch (with power applied at each switch for it's cameras), and then run a single CAT5 cable to the next building into that building switch's uplink port. The most switches on a single chain would be 4 with a total of 55 megabits of video data. Some chains would be shorter with fewer cameras and switches. There would be LESS than 250' between each switch. The end of each chain would terminate to a video surveillance NVR.
Is this possible, chaining the switches like this?
Thanks for any input.
Ensure you get good switches with large bandwidth backplanes. Each switch should be able to carry the traffic of the cameras on it and all the cameras daisy chained to it. Each port that connects the switches will also need to handle the full bandwidth load of everything before it. Generally, this setup leads to major performance problems. Furthermore, a switch failure can take down EVERY camera instead of just a few. The cost of running cables is usually worth it in the long run. – MaQleod – 2014-08-02T04:57:29.950
With 250' (minutes) you mean 250'' (inch)? – Max Ried – 2014-08-02T11:45:18.697
Nope, I meant 250' (250 feet). – bill – 2014-08-02T19:08:27.320
The biggest problem I see with this is nightvision (separate light source for nightvision) for the cameras and heaters for the cameras. Heaters for the cameras if in bad weather location. All of which puts the poe at a disadvantage. Even POE+ is a little short on power for heaters and night vision. Some of the cameras I have seen take more than POE+ can give. – None – 2015-01-22T16:02:17.250
