A well-thought-out solution for a safer home
You can know on the go all the activity happening at home. This kit offers a one-stop solution to free you from worrying about anything from home break-ins to family emergencies. The seniors and kids at home alone can also send a request for help just by using the smart button.
Trusted security at your fingertips
Know and be notified by using the EZVIZ App. You can receive mobile alerts on all detected activities. Feel free to set your sensors on a time schedule, or manually arm or disarm the whole system whenever you stay out of sight.

Connects Sensors via ZigBee 3.0, Supports Wired or Wi-Fi Internet Connection AND Supports 20 Alarm Sounds
Get informed whenever someone sets foot in your room
Install the PIR motion sensor in your room, and fine-tune the detection coverage using the pet shield included in the kit to partially cover the sensor. This will ensure it only alerts you about human activities, rather than every time your pet runs through the room.
Know if your doors are left open, or get openedKnow if your doors are left open, or get opened
Doors, windows, closets – forget about having to check and re-check to confirm they’re shut. If anyone forcibly breaks in, the home gateway will set off a loud alarm, and a mobile alert will reach your phone immediately.
Control with a simple click
Use the smart button in two ways – switch on and off your entire sensor system, or press it to send an emergency alarm. Use the peel-and-stick method to place it anywhere within your reach – you can even carry it in your pocket.
Easy integration with your smart home
Link your sensor kit with your EZVIZ cameras² for enhanced protection. If you use a local storage card or have subscribed to EZVIZ CloudPlay, the camera can begin auto-recording for 5 seconds whenever the sensor detects an activity⁵. You can also voice-enable the sensor system with Google Assistant or Amazon Alexa.
