Determine whether your consumer unit bell transformer provides sufficient Volt-Amps (VA) and operating voltage, and calculate the exact angled wedge required to eliminate masonry glare.
Diagnostics & Wedge Advice
Transformer Power Rating
INSUFFICIENT (8V)
Will cause chime hum, battery depletion, or Wi-Fi disconnection.
Recommended Wedge Angle
15° Corner Wedge
Angled towards the front path to prevent IR white-out reflection.
Recommended DIN-Rail Upgrade
Hager / BG 24V 30VA
Installed cleanly inside consumer unit alongside 6A lighting MCB.
Why IR Glare Blinds Cameras: If mounted flat on a side reveal, 40% of the camera's night-vision LEDs bounce off adjacent bricks, blinding the optical sensor. A wedge bracket re-centers the focal cone.
Transformer Volt-Amps & BS 7671 Compliance
Smart doorbells maintain continuous 2.4GHz/5GHz Wi-Fi transceivers, PIR motion sensors, and live video streaming buffers. Unlike simple momentary mechanical push-buttons, they draw continuous quiescent power:
Minimum Recommended Power = 24V AC @ 1.25A (30VA) | DIN-Rail Bell Transformer to BS EN 61558-2-8
When a visitor pushes the button, the doorbell momentarily shorts the power loop to fire the internal solenoid chime plunger while simultaneously transmitting video packets. Without a 20VA–30VA transformer, the sudden voltage dip triggers a processor restart.
