TLC-510A variant IPC_MS1NA45MP and no RTSP ports open

user_829841447919777

Good morning, I purchased recently a Reolink 510A, which I hoped would work well with AgentDVR (iSpy) software.

The older / different variant IPC_523128M5MP_V2 seems to work just fine and the connections are listed without any problems. The variant I received i.e., IPC_MS1NA45MP, does not seem to have any ports open at all. I did an nmap on both devices - they are definitely different.

IPC_523128M5MP_V2 has plenty of ports open, including 554

IPC_MS1NA45MP seems to be locked down

Is this by design? Is there any newer / different firmware for IPC_MS1NA45MP variant that opens port 554 to enable operation as a network camera? I am running the latest firmware available for IPC_MS1NA45MP variant.
thank you!
