A rain hood that sits over your doorbell and keeps direct rain, low winter sun and driving weather off the lens and the button.

Getting the size right

45mm is the inside width of the cover, not the outside measurement. Measure the width of your doorbell - its width, not a diameter or a diagonal - and pick a cover at least 5-10mm wider than that. More clearance is better than less.

You are not trying to get a snug fit. That gap is what stops the doorbell's infrared lights bouncing off the inside of the cover at night and washing the picture out. Too tight and you get glare. So this 45mm cover suits doorbells up to roughly 35mm wide.

Not just doorbells

It works on anything flat on an outside wall that would rather not be rained on - access control readers, entry keypads, fingerprint scanners and digital door locks. Keypads especially: once water gets behind the buttons, the rubber and the printed digits are the first things to go, and a cover buys you years. Same rule on size, though - measure its width and leave yourself that 5-10mm.

  • Rain and glare protection for the camera and the button
  • Single-hole design - one screw and one wall plug supplied, so there is nothing else to buy
  • 3D printed in high quality recyclable bio-plastic
  • Shaped to shield from above while leaving the lens, button and motion sensor clear

Fitting it

Screw fitting is the only mounting method - there is no adhesive version. The good news is you do not need to take your doorbell down.

  1. Check the height first. Hold the cover where you think it should go and look at the live camera view in your doorbell app. Move it up or down until the picture is clear.
  2. Check it at night too - this is the one people skip. After dark the doorbell switches on its infrared lights, and if the cover sits too close to the lens that IR bounces straight back off the underside and washes the whole picture out. A cover that looks perfect at noon can blind the camera at 2am, so do the night check before you drill.
  3. Mark, drill, fit. Once you are happy with both views, mark the hole, drill it, plug it and screw the cover on.

Frequently Asked Questions

What size is this cover?
45mm is the inside width of the cover, not the outside. Measure the width of your doorbell - its width, not a diameter - and pick a cover at least 5-10mm wider than that; more clearance is better. That gap is what stops the doorbell's infrared lights bouncing back off the inside of the cover at night, so do not aim for a snug fit.
What does the cover do?
It is a rain hood that sits over your doorbell to keep direct rain, sun glare and weather off the camera and button - helping it last longer and see more clearly.
How do I fit it?
It screws to the wall - that is the only mounting method, there is no adhesive option. One screw and one wall plug come with it. You do not have to take your doorbell down: hold the cover in place, check the camera view in your app, then mark, drill and fit.
Why should I check the camera view at night before drilling?
Because after dark the doorbell turns on its infrared lights, and if the cover sits too close to the lens the IR bounces off the underside and washes the picture out. A position that looks fine in daylight can ruin the night view, so check both before you make a hole.
Will it block the camera or sensor?
No - it is shaped to shield from above while leaving the lens, button and motion sensor clear, provided you set the height using the app view as above.
Which doorbells does it fit?
It is universal and works across many brands - and it is not only for doorbells. Plenty go on access control readers, entry keypads, fingerprint scanners and digital door locks. What matters is width, not badge: this one suits anything up to roughly 35mm wide, which leaves 5-10mm of clearance inside the 45mm opening. Measure yours before you order.
