Start by identifying the alarm or automation system’s supported wireless protocol, operating frequency, receiver, and sensor types, such as contact, motion, shock, flood, or temperature sensors. Then match the wireless sensor to those requirements, checking the system documentation for enrollment, supervision, encryption, battery, and two-way communication support before installation.

When placing wireless sensors on doors, windows, or glass, check panel and frequency compatibility, mount contacts with the magnet aligned, allow for the door or window’s movement, and select a slim or low-profile design when space is limited. For glass-break or shock sensors, follow the device’s mounting requirements, while outdoor, flood, and temperature sensors need placement that exposes them to the condition being monitored and protects them from unintended damage.

Compare whether the sensor is battery powered, which battery type it uses, expected service life, and whether it reports low-battery or tamper conditions to help plan installation and maintenance. Confirm that the sensor’s wireless protocol, operating frequency, encryption or supervision features, and one-way or two-way communication match the security or automation panel and the intended installation environment.

For indoor access monitoring, choose wireless door and window contact sensors, including slim, mini, flat, and two-way designs, or use a wireless shock sensor for glass protection. Outdoor contact sensors support gates, doors, and windows, while wireless flood and temperature sensors monitor water conditions and ambient temperature, and wireless motion detectors monitor movement in indoor areas.
