Make your home safer with the Ezviz T9 wireless siren. Link this loud siren to your Ezviz A1 base station and an 85dB alarm will sound if an unexpected visitor is detected in your home. The alarm works with, among other things, the infrared detector, door sensor and the IP camera from Ezviz. That way, someone never enters your house unnoticed. The loud alarm not only ensures that you get a notification, but also deters intruders. You manage this siren from the Ezviz app.
