Alarm in:
Use the alarm input to connect external alarm devices such as
door contacts or sensors:
–
TTL logic, +5 V nominal, +40 VDC max, DC coupled with
50 kOhm pull-up to +3.3 V.
–
Configurable as active low or active high.
A zero potential make-contact or switch can be used as the
actuator (use a bounce-free contact system).
Note:
If IR illumination is used, the alarm interface provides a stable
switching control of the day/night function of the camera.
