Thanks David... I forgot about that one! As I recall V1572 was sent out by Reolink Support (when requested) and was to
fix RTSP streams. As long as we're digging up firmware versions I figured Id try to net them all out here. If anyone knows of any versions or corrections I missed please let me know. FYI: There were two earlier versions that I know of (V1354 POE and WiFi) ... but neither were available for download they just came preinstalled.
Not 100% sure but it seems (if arranged numerically by version number... the versions to date have been as follows. V1354, V1459, V1572, V1859, and V2017
V1354 (earliest known firmware factory pre-installed version
WiFI v3.0.0.1354_22092302"
