Quick Answer
Why is my door opening randomly?
This is often 'ghosting' caused by radar interference or sensor drift. In Nunhead, we see this frequently with older analog sensors. We upgrade these to digital units that filter out environmental noise.
Component Analysis
Brushless DC Motor: We test internal resistance to detect winding faults common in high-cycle Nunhead venues.
Activation Logic: False triggers are common. We adjust the radar sensitivity to filter out cross-traffic and rain.
