NetCamera NVW
A02-IPCAM4-W54 68
APPENDIX D: GPIO
Its back panel contains 3 pairs of connectors (2 input and 1 output) allowing the
camera to communicate with different elements of a building, such as electric doors
and light switches or security related devices such as alarms.
Most of its applications are security. Warnings to the one break into house/building.
Some people user it to setting fire alarms.
NetCamera NV supports 2 sensors in (DI) and 1 alarm out (DO).
External DI sensors can be attached via the GPIO port at the rear of the camera. The
external sensor can be normally open, or normally closed. A normally open sensor
(NO/COM ) is like an open switch that closes when triggered. A normally closed sensor
(NC/COM) is like a closed switch that opens when triggered. This must be set correctly
for an external sensor to function properly. You can connect up to two DI sensors to
the camera.
An external DO alarm can also be attached to the camera via the GPIO port at the rear
of the camera.
Under DI Configuration, select Normal Open or Normal Close for each DI1 and DI2.
