1 Terminal Block
Terminal block connections:
Connect wires to the terminal block by: strip the insulation back ½” from the end of the wire; press in on
the upper tab above the lower wire opening; while holding the tab in, insert the wire; release the tab,
pull back gently on the wire to lock it in, and the wire should be retained. Nominal 22-24AWG wire
recommended; maximum 18AWG wire may be used.
-GND: Ground pin
-D/N Out: Day/Night control output
If the camera will be used to send out a D/N signal as an external D/N control for any other unit, then
the D/N mode of that unit can follow the D/N mode of the camera.
When the camera is at Day mode, it will send out a Low level (0V) signal to any external device.
When the camera is at Night mode, it will send out a High level (3.3V) signal any external device.
-D/N In: Day/Night control input
To use this terminal to control D/N operation, set the D/N selection in the OSD menu to EXT (see
Section 5.6), so that the camera will follow an external Day/Night signal instead of the internal AGC
level to control any color to B/W switching (examples of possible EXT control devices are: an
‘external’ light level sensor such as the one mounted in the front face of the camera, an auxiliary
light sensor mounted external to the camera, or a control voltage applied to the D/N In terminal). If
the “D/N In” terminal is used, it will override the signals from the built-in or auxiliary light level
sensors and will command the camera into B/W operation when it is switched to a low voltage level
(grounded), or into COLOR operation when it is switched to a 3.3V ‘high’ level; however, if the D/N
In terminal is open/‘floating’, the AUTO operation switchover from color to B/W will be controlled by
the light sensor at the front of the camera body. See Section 5.6 for more information.
-Motion: Alarm output for motion detected.
If the alarm output is connected and a motion is detected, not only will the message “MOTION
DETECTED” appear on the screen, but the camera also sends out a high level (3.3V) signal at the
motion alarm output. If no motion has been detected, a low level (0V) signal is sent out to the
motion alarm output.
-RS485-/RS485+: Connect to RS485 for remote control by keyboard or DVR. RS-485 parameters are
set in the OSD menu.
