Outdoor contact sensor for home security that sends real-time alerts when gates, sheds and windows open. That extra awareness brings peace of mind for anyone storing tools, bicycles or seasonal items outside. Is the Ring Alarm Outdoor Contact Sensor the simplest way to extend alarm coverage to outbuildings?

⚡ At a Glance
  • Weather Resistance: Weather-resistant casing designed for outdoor use with reliable operation in most climates
  • Best for: Homeowners who need alerts for gates, sheds, garages and outbuildings
  • Not ideal for: Users without a Ring Alarm Base Station or those using non-Ring alarm ecosystems

Battery-powered outdoor contact sensor sends open and close alerts and can trigger the siren when the Ring Alarm is armed. Weather-resistant housing and included mounting tape or screws make installation straightforward, though a Ring Alarm Base Station is required.


Instant intrusion awareness – Thanks to real-time open/close reporting

Detects open and close events and reports them to the Ring Alarm Base Station, which can then send push notifications or activate the siren when the system is armed in Home or Away mode.

Immediate alerts let owners know when gates or outbuildings are accessed, giving time to check camera feeds or dispatch help. Automatic siren activation acts as a deterrent without manual intervention.

Built for outdoor mounting – With weather-resistant, battery-powered design

Weather-resistant enclosure and battery power allow placement on exposed gates, sheds and windows without needing mains wiring, and mounting tape plus screws are supplied for a tool-free option.

Flexible placement suits a wide range of outdoor locations where a wired sensor would be impractical. Quick installation reduces hassle for garden gates and remote outbuildings.

Plays well with an existing Ring system – With compatibility for Ring Alarm generations

Works alongside a Ring Alarm Base Station and is compatible with 1st and 2nd generation Ring Alarm devices and accessories, enabling integration into existing alarm setups.

Ideal for households already using Ring Alarm gear, as sensors add coverage without swapping the central hub. Centralised alerts and siren control keep all responses within one system.
