EZVIZ T1C PIR Motion Sensor
The EZVIZ T1C (CS-T1C-A0-BG) is a small indoor PIR motion sensor that detects human movement up to 7 m away and sends an alert to your phone through the EZVIZ app. It connects over Zigbee 3.0 to an EZVIZ Home Gateway and runs on a CR2450 coin battery for up to 2 years in energy-saving mode.



PIR motion detection: The sensor uses passive infrared to detect the body heat of a moving person, with a range of up to 7 m (23 ft) and a 90° detection angle. For wall mounting, a height of 1.8 to 2.5 m is recommended.
Adjustable 360° mounting: The round sensor can be rotated a full 360° to find the best detection angle. It installs with peel-and-stick adhesive, so no drilling is needed.
Pet shield: A pet shield can partly cover the sensor so it reacts to people rather than every time a pet runs through the room, which helps reduce unwanted alerts.
Anti-tamper alarm: You get an alert immediately if someone forcibly removes the sensor cover.
Long battery life: The included CR2450 battery lasts up to 2 years when energy-saving mode is enabled.
Works with
An EZVIZ Home Gateway (Zigbee 3.0) and the EZVIZ app.
Good to know
The T1C does not work on its own: it requires an EZVIZ Home Gateway, which is not included. It is for indoor use and does not connect to Wi-Fi directly.
