Hello,
I am completely new to using PTZ cameras. I have always used fixed setups previously, and I am in a situation where I may need to install multiple PTZ cameras.
Do PTZ cameras require an external controler, or are the DVR's that state they work with PTZ able to control them on their own?
For cabling standards, is RS485 absolutely required or can you go with an 18/2 wire and get by?
Any advice or great writeups on this would be very helpful. Thanks!
