First of all let me tell you right off I am a newbie. I am an IT Professional by trade and have recently been thrown into the security cameras, alarm and door access control systems.
I have a client who run an apartment complex in the center of the property is the main office/clubhouse with two 16 channels DVR and two 16 port power supplies. Besides the Main Office/Clubhouse building, there is 7 apartment buildings (Building A - G)
Location/# of Cameras
- Building A/4
- Building B/5
- Building C/6
- Building D/3
- Building E/3
- Building F/3
- Building G/3
Some of these cameras are some distance away from the centrally located Main Office/Clubhouse that when you look at a live feed from the DVR, the video signal is very bad. What I want to know is there a maximum distance for a video signal and for power cable. They are using the Siamese cable that has the video/power together. I hear that power will drop or degrade over a certain distance. I am sure the same is true for video signal.
I also have one other problem, let say you are getting a bad picture on one of the channels on a DVR, let say "Channel 1". You unhook cable from DVR and hook it up to a camera viewer and the picture looks great. What could be causing this problem?
Thanks. I will try to post up a map of apartment complex and distance from Main Office to furthest camera later today.
