Hikvision security cameras are good, but NVRs can really drive you mad before you get them working.
Few notes on setting up DS-7608NI-E2 with Hikvision IP cameras.
What: As soon as you switch the unit on, it starts beeping. Beeps come in series and constantly keep repeating. There is nothing about it in the manual.
Why: The unit has detected that it either does not have a HDD installed, or that HDD is not formatted (initialised).
How: Ignore the beeps, go to system menu, find the section about the disk management ant initialise the disk. As soon as you start formatting, the annoying beeps will stop.
What: You easily set up continuous recording, but you can’t set up motion detection. Obviously the Hikvision NVR fails to detect motion. You check and re-check the settings, everything seems to be correct, but motion detection just does not work.
Why: The unit needs administrator password for the cameras. It is not obvious in the Web interface, though is clear enough in the console GUI (direct connection to display/screen).
How: Provide the administrator credentials. I suggest changing the admin passwords for cameras to numbers only, as I suspect that letters in the password confuse the NVR .
You can see that after you change motion detection settings in the NVR, they change accordingly in the IP camera itself too. The NVR is giving orders to cameras and that’s why it needs the admin password.
What: It is quite likely that, while you struggle with IP camera login credentials, you will experience a situation where not only the NVR fails to connect to the cameras, but you also loose ability to login into the cameras via web interface and keep getting cryptic message “Network abnormal”.
Why: Not really clear, but it seems that the NVR confuses cameras by constantly trying to log in with incorrect credentials.
How: Just power off the respective camera by pulling the plug and then switch it on back again. It should be working now. You may still need to reconfigure or shut down the NVR before you are doing that, so that it does not mess it all up again before you even get back to your browser.
