Have you connected your Indoor Camera and Sensor Bridge
Before installing any sensors, make sure that your Indoor Camera and Sensor Bridge are properly connected and online. This is important as the sensors will not be able to be installed without first completing this step.
Where to place
Place your Contact Sensors on doors, windows, or anywhere you want to see if something opens.
Here are a few suggestions:
On doors and windows
On sliding doors or patio entrances
On garage doors
On cabinets or cupboards
Feel free to place your sensors in other locations that suit you.
