Audio Input
•
The audio input interface standard RAC socket, 2Vp-p, 600Ω.
NOTE: The audio input resistance is a little high, please use an active sound collection device or active
microphone. The audio signal cable should be kept away from the interference of strong electromagnetism
and the city electric power grid.
Network Input
•
The network input interface is RJ45 10/100M self-adaptive.
NOTE: Confirm that the network band width is enough for transmitting high definite images smoothly.
Alarm Input and Output
•
The alarm input device should be the type of GND connected alarm or voltage input alarm, which can be set
as N/O, or N/C.
The requirement of signal input level for voltage alarm type is: low level 0~2V, high level 5~15V.
The green angle pins of the signal cable are designed for access of PTZ and alarming devices. Please
follow these steps to connect.
1. Pull out the angle pins that are inserted in the alarm input and output interfaces.
2. Unscrew the screws with a micro Philips screwdriver, insert the signal cable into the interface under
the spring, then tighten the screws.
3. Plug the connected pins into the green angle pin socket.
PTZ Input (Pan-Tilt-Zoom)
•
Connect the PTZ control interface to the RS485 interfaces of the rear panel. The connection method is
similar to the method above.
NOTE: Please refer to the PTZ manual for setting specific parameters, for some PTZ devices contain
multiple telecommunication protocols, baud rates and IDs.
Video Output: VGA/Monitor Input
Video output interface: TV and VGA, which can work together simultaneously.
NOTE: VGA and TV cannot be in the operation interface simultaneously, but can be switched by mouse,
panel or remote control in the menu.
