Nivian

Nivian brings alarm, camera and doorbell together in one clear Tuya app. The Smart Alarm kits come with a Wi-Fi hub, motion detector, door contact and remote control, expandable with up to 60 wireless accessories including smoke detectors and outdoor sirens. The panel even has GSM backup, so you still receive alerts during internet outages.

For video, choose battery-powered Wi-Fi cameras with a solar panel or a complete NVR kit. The cameras recognise people, send push notifications and store clips locally or in the cloud.

The video doorbell lets you see and hear who's ringing; from the app you can open the garden gate right away or send a spoken reply.

All Nivian products work with Google Assistant and Alexa, so routines – such as "alarm on, lights off" – start with one voice command. Thanks to easy QR setup and keenly priced add-on modules, you build a flexible smart home system step by step that grows with your needs.
