Unit connectors
Network connector - RJ-45 Ethernet connector. Using shielded cables is recommended. Use
care when inserting and removing the network cable.
I/O terminal connector - Used in applications for e.g. motion detection, event triggering,
time lapse recording, alarm notifications, etc. It provides the interface to:
Power/Audio - Power, auxiliary power, GND and audio.
•
Outputs - 4 solid state relay outputs. These can drive a maximum load of 50V DC
•
or 35VAC at 500mA or they can drive heavier loads by connecting additional
relay circuitry. If the output is used with an external relay, a diode must be con-
nected in parallel with the load for protection against voltage transients. The ter-
minals use a photocoupler and are electrically isolated from the other internal
circuitry.
Inputs - 4 alarm inputs. Used for connecting external alarm devices and trigger-
•
ing images for specific alarm-based events. The input is typically connected to a
motion detector or any other external security device, and images can be
uploaded whenever the detector is activated. The inputs are allowed 3.3 - 40VDC.
The terminals use a photocoupler and are electrically isolated from the other
internal circuitry.
