Mounting a doorbell camera without drilling

Every one of these approaches trades something. Knowing which trade you are making is the difference between a camera that survives a winter and one that ends up face down on the step.

Clean with alcohol, not household cleaner

Surface cleaners leave a residue designed to repel water, which is the opposite of what you want. Isopropyl alcohol leaves nothing behind. Let it dry fully.

Apply in the warm part of the day

Check the tape's stated minimum temperature and respect it. If it is cold, warm the surface first and give the bond longer before hanging any weight.

Press hard, then leave it alone

Firm pressure for a full minute across the whole plate, then leave it for the dwell time on the packaging, commonly a day, before mounting the camera. This is the step people skip and it is the one that decides whether it holds.

Add a tether if the camera is worth stealing

An adhesive plate resists a steady pull far better than a sharp twist. A short security tether turns a walk-away theft into a job needing tools.
