What to do if the MT Vision Digital Camera has no alarm or alarm failed?
- KKathleen HollandAug 12, 2025
If your MT Vision Digital Camera's alarm is not working or failing, it could be due to several reasons. The alarm PIP setting might be incorrect (refer to the manual for details). The issue might arise if the camera is blocked by moving objects or barriers, or if there's interference from light, thunder, infrared, or microwaves. The stored recording image may remain unchanged if the pyroelectric sensor's angle is wider than the camera's, triggering it beyond the camera's view. Objects passing through the recording area too quickly (less than 2 seconds) can also cause this. Lastly, a dirty Fresnel shell can be the culprit.
