Manual for DVR - GoldenVulture - 04-18-2015
I've just installed a security camera setup for the Pub/Hotel in the next town. I was reading through the manual.
Quote:2.4.2 Video output connections and options
The video output is divided into PAL/NTSC BNC(1.0VP-P,75Ω) and VGA output(selective
configuration).
When replace the monitor by the computer display, there are some issues to notice.
1、Do not stay in the turn-on state for a long time.
2、Keep the computer display normal working by demagnetizing regularly.
3、Stay away from the electro magnetic Interference.
TV is not a credible replacement as a video output. It demands reducing the use time and control the
power supply and the interference introduced by the nearby equipments strictly. The creepage of low
quality TV can lead to the damage of other equipments.
2.4.3 Audio signal input
Audio port is BNC connection.
The input impedance is high so the tone arm must be active.
The audio signal line should be firm and away from the electro magnetic Interference and connected
credible which avoid false and joint welding and oxidation. The high voltage current should be avoided
especially.
2.4.4 Audio signal output
Commonly the output parameter of DVR audio signal is greater than 200mv 1KΩ(BNC) which can
connect the low impedance earphone and active sound box or other audio output equipments through
power amplifier. If the sound box and the tone arm can not be isolated, howling phenomena is often
existed. There are some methods to deal with the above phenomena.

Did you put one in the ladies room and what is the IP and port.

No and I've still to finish off setting it up so no outside connection yet. there is only four cameras so far, it is capable of running eight.
It's the second one I've setup for the guy who runs the Hotel. He also runs one in my town which I've already setup with six cameras. They're going to be setup so both systems can be viewed/controlled remotely or from either pub.
Thinking back, cameras in band rooms [ at venues ] would be primo viewing.
