You rent the home. Not the security.

On a clean, smooth and dry surface, yes. Frames, doors, tiles and smooth plaster are no problem. Where you need to take care: coarse textured wallpaper, chalk paint and powdery walls offer little grip, and in a bathroom or unheated garage temperature changes can pull at the adhesive strip. Degrease the surface first, press firmly and give it a day to cure before you rely on it.

You take everything off and bring it with you. No technician needed to remove it, no buy-out fee and no relocation charge — with a subscription system those costs do apply, because the installation is tied to the address and not to you. Warm the adhesive strip briefly with a hairdryer when removing it and it will come off without pulling; any leftover glue wipes away with a little rubbing alcohol. Either way, there are no holes to fill. In your new home you stick the sensors back on and pair them with the same control panel — you're usually fully protected again within an hour.

For the inside, usually not: you don't change anything about the home and you leave no traces when you leave. If you do want to attach something to the façade, the balcony railing or in a shared space, you'll need permission — that falls outside the part you rent. Also good to know: in the Netherlands, smoke detectors are the landlord's responsibility. If there aren't any, ask for them; if you want to add an extra one yourself, that's perfectly fine.
