The camera's 6-terminal strip provides: (1) Positive power input, (2) Negative power input, (3) Egress input (N.O., –) for an optional request-to-exit device, (4) N.O. relay output for fail-secure lock operation, (5) N.C. relay output for fail-safe lock operation, and (6) Common output wired to the lock device's power supply. For 16VAC doorbell installations, wire directly from the doorbell's transformer.
Resetting/re-pairing the original camera and monitor: remove the camera from the bracket, disconnect and reconnect power if the tamper alarm sounds, then hold the reset button 3–4 seconds until it beeps once (pairing mode, ~15 sec window). On the monitor, select "Match code" under Setup → Pairing.
Pairing an additional monitor: on the first monitor select "Give code" (Setup → Pairing); on the new monitor select "Receive code." Up to 3 monitors total are supported.
Pairing an additional camera: hold the new camera's reset button 7–8 seconds (beeps confirm timing), then select "Give Code" on any paired monitor.
Triggers whenever the camera is removed from its bracket. To disable: return the camera to the bracket, or repeatedly press "OK" on all paired monitors; if it persists, cycle power/battery on the camera and monitors. The alarm can be permanently disabled via Setup → Alarm Setting.
| Blank monitor screen | Press ON/OFF or OK to wake it; check battery charge; plug the charger directly into the monitor. |
| Monitor not charging | Clean battery and monitor contacts; ensure kickstand is extended in the charger stand; check the power adapter connection; try connecting the adapter directly to the monitor. |
| Monitor doesn't ring | Check volume, standby mode, and that the monitor is seated in its mounting bracket. |
| Monitor can't connect to camera | Confirm pairing and that the monitor is within wireless range. |
| Poor image quality | Adjust brightness, clean the lens, reposition the camera, and move the monitor away from interference sources (microwaves, TVs, lamps). |
| Can't activate the relay | Confirm two-way communication is active (microphone icon lit, no "X") and check wiring between the camera and lock device. |
