IPC cannot be accessed?

A: Possible causes:

• Confirm that the power supply is connected.
• Confirm that the IPC network is good and properly connected.
• Confirm that the IPC program and storage device are compatible.
• Confirm that the IPC has been completely started.
• Confirm that the IPC blacklist has no problem.
• Confirm whether the IPC port has been changed; by default, the private protocol is 37777 and the onvif is 80
• Confirm that the IPC is not being accessed too much, resulting in no image being transmitted.
• For a third party IPC, confirm that the port number, time zone and time of the IPC are consistent with those on the NVR. Confirm that the current network environment is stable.
