Motion detector with brightness sensor – outdoor

Movement outside? It's detected!

Do you sometimes feel uneasy at home when it gets dark? Do you want to be able to open the door safely and quickly when you get home late? If so then it's worth getting the weatherproof Homematic IP motion detector. It reliably monitors the outside of your home. If it detects movement - including your own - it switches on the light and also triggers an alarm if you want it to.

Glühbirne

Powerful, whether it’s light or dark

Besides switching on your light when it's dark, the integrated brightness sensor will do the same at dusk or on cloudy days if you want it to.

The powerful lens detects movement at a distance of up to 12 metres. The sensor can also be rotated through 360 ° to cover the desired area.

You can also install the motion detector outdoors or in the garage.
This is thanks to the wide temperature range of -20 to +40 °C and weatherproof housing (IP44).
