Top critical review
Poor software quality
Reviewed in Australia on 21 January 2021
Out of the box, the NVR (model RLN8-410) won't work with a modern web browser as it required Flash (which was killed off last year). A firmware update added flash support, however with the 20102144 firmware (v1.0.263 in the web UI) the NVR repeatedly crashes when connected to the Internet. The software overall is pretty poor and replete with spelling errors. Playback via the web UI is very limited, you can't scrub back and forth nor can you even fast forward or rewind - Play (in real-time) and Stop is all you have.
The Android app has better controls, but won't work when connecting via IP (as required when the NVR is disconnected from the Internet, as above). Sigh.
I've previously used Ubiquiti video, and though they're far from perfect, they do get most of the basics right.
