Uniview + MQTT
Uniview cameras can email when they see something, but most don't speak MQTT, and the few that do still can't publish a hosted snapshot or say what was actually in the frame. NVR Bridge sits in between and does the translation. Every event is published to a topic on your own broker — the language Home Assistant, Node-RED and openHAB already speak — so whatever you've already automated can act on it. No Uniview NVR and no extra licence — the camera does this on its own.

}How it works
Create a camera in NVR Bridge and it gets its own private inbound address, something like k7m2p9@relay.nvrbridge.com. That address is how we know which camera an event came from.
In the camera's web UI, go to Setup → Network → Email, then enable email under Alarm → the event you want. Set the recipient to the address above, and use our SMTP server and short password — or your own mail provider, if you'd rather.
Add an MQTT notification with the broker's host, port and credentials, then choose the topic, the QoS and whether to retain. If the broker only exists on your LAN, give us SSH details instead and we'll publish through a tunnel — nothing is exposed to the internet.
Walk past the camera. The event lands on your timeline within seconds and the MQTT alert follows. Every delivery is logged with its result, so a failure is something you can read rather than guess at.
What you get
Questions
No. Give us an SSH host and key and we'll open a tunnel for the moment it takes to publish, then close it. The broker keeps listening on your LAN only, exactly as it does now.
JSON by default — camera, time, event type, snapshot links and any detections. If the receiver wants a particular shape, write the body yourself with placeholders.
Any model with email or FTP alert settings, which is effectively all of them. We don't need ONVIF, RTSP or a particular firmware version. Uniview cameras will happily send to an external address, which is all we need — no extra licence, no NVR module.
No. The camera talks to us over the same outbound connection it already uses to send email. There's nothing to install on your network and no inbound port to open.
Add a camera, point its email at the address we give you, and watch the first event land. About five minutes, all of it in a browser.
