Chapter 1 Getting Started
Hardware Installation
•
The DO+ pin provides 5V output voltage, and the max. load is 50mA.
•
The max. voltage for DO- pins is 80VDC (External power). In order to control AC devices, the above
diagram can be taken in consideration. The diagram uses a relay to control the ON/OFF condition
of the AC device.
•
An external relay can be triggered by using DO+ or by an external power source, depending on the
type of relay you use.
•
In case of using an individual relay (instead of using a relay module), for protection against voltage
or current spikes, a transient voltage suppression diode must be connected in parallel with the
inductive load.
Step 8
Attach the included alignment sticker to a preferred location. Drill holes for mounting screws and if
preferred, drill one or two routing holes.
Step 9
When fastening the screws, do not completely tighten the screws. Pass cables through the routing holes,
and then mount the camera by passing the screw heads through the keyhole slots. Turn the camera
counter-clock wise, and then fasten the screws.
