Thank you.
All power to the cameras will be at the camera, not going through the Cat 5.
The camera at the gate will most likely be wireless (currently looking at Swann Black Knight wireless..I like its night vision but day picture are washed out).
Another reason for the Cat 5 is it is already in place except to gate where I will go wireless most likely. Technology being what it is, with Cat 5 I can swicth to IP cameras in the future if for some reason that become a better option.
