The alarm can be wall-mounted using the provided bracket, screws, and wall plugs. Consider the detection range and sensitivity when choosing an installation location.
- Fixed Installation: Use the screws and wall plugs to securely attach the mounting bracket to a wall or fence post.
- Device Attachment: Slide the alarm unit onto the mounting bracket until it clicks into place.
- Optimal Placement: For best motion detection, install the device where movement will cross its detection path (110-degree angle, up to 20 feet). Avoid direct sunlight on the sensor if possible to prevent false triggers.
