Know if your doors are left open, or get opened

Can’t remember whether you’ve shut your windows tight when leaving home? With the T2C, you can check the open/close status anytime and anywhere on your smartphone. And if someone tries to open a door or window, you’ll receive alerts directly to your smartphone.


Install it anywhere for the protection you need

This mini-size sensor fits easily in your home environment – just peel the sticker and place it anywhere. It makes your home access safe, and guards your loved ones while you’re out.


Link it up with your camera to see who enters

Integrate your T2C with your EZVIZ cameras¹ for enhanced protection – all using the EZVIZ App. You can set the linked camera to begin auto-recording for 5 seconds whenever the door is opened

Anti-tamper alarm for added protection

For extra peace-of-mind, the sensor alerts you immediately when anyone forcibly removes its cover.


Long-lasting performance you can trust

The T2C is designed with high energy efficiency, operating for up to 2 years⁴ with the included battery cell. Enjoy the reliability and reduced energy costs with the T2C.


Expand your EZVIZ alarm system

The open/close sensor can be conveniently added to your EZVIZ sensor system for expanded protection. You can manage and arm the system using the free mobile app from EZVIZ.


1 The gateway is not included in the purchase of the sensor. The sensor only works in conjunction with the EZVIZ Sensor Kit.
2 The T2C Open/Close Sensor must first connect to the gateway to link with EZVIZ cameras. The sensor can only work with EZVIZ wired cameras that are launched with version 5.3.4 or later firmware. Please contact the EZVIZ support team to confirm camera compatibility.
3 The current version only allows the C6 Smart Camera to auto-track activities upon sensor detection. Other pan/tilt cameras will only record at its original fixed viewing angle when the sensor detects an activity. The sensor-triggered auto-tracking feature is under development and will likely to be available on most EZVIZ indoor PT cameras in 2022
4 Data from EZVIZ lab test results, based on a usage of 30 opening/closing actions per day. May vary due to activity frequency and other environmental factors.
