Q: How the alarm input works.
A: I need a short information on how the input / input of the camera must be connected. In the manual the input / input is described with + and - (see attachment). How is this information to be interpreted? Does this mean that a pot. Free contact of an external relay must be connected to the marked connection points?
Information about the alarm I / O can be found in our online documentation:
A terminal, potential-free, must be connected to the alarm input, which opens or closes a relay in the event of an alarm (N.C. or N.O.). You can also test the functionality very easily by bridging the two contacts with a wire. When you enter the input on N.C. You should receive a permanent alarm as soon as you remove the wire.
