Today someone requested me to search something in my IP Cam several days ago, and there's this strange popup that says that No Record File. I check playback for other IP Cam and it's exist, I try to ping the IP Cam and it can, I try to restart the IP Cam and the NVR but still not recording, I try to check the configuration that I believe I didn't change them and it's true the configuration still the same. Any ideas of what happen guys?
