I don't know. Does it unpack ok?

Excellent! That's good to hear, thanks for the update.

Int It's a bit of a mystery why it's behaving differently as opposed to just doing a fairly quick restart as it did to begin with. Does the web GUI work and look normal? How close to actually working does it seem to be?

What does windows task manager show for the offending high CPU processes?

That is correct, the NVR has administrative control of the cameras via the Hikvision command&control protocol and the admin userID/password. When the camera is 'activated', such as when a new Inactive camera is first connected, the camera IP address is assigned by the NVR to match the IP address...

It is quite complicated as it involves disassembling the code of the control program, working out what it's doing (many thousands of lines of code) and finding the part that sets the way of working. Working up a patch to change that. But a hard part is being able to unpack and decrypt the...

Haha! Yes, I've done that, just for fun, on some of the value series cameras. It's the same firmware, that just behaves with different capabilities depending on the model data from the bootpara data that's written in to the camera at manufacture. Same hardware as the more expensive models...

It looks to me like these are 'dumbed down' cameras with no smart event capability. That significantly reduces the ability to fine tune the event generation to avoid getting those that you do not want. Motion detection is the most basic of event types and is quite limited.

Do you mean reading the flash gives consistently the same results? And this didn't fix it? Which is why I said 'not being written correctly' as opposed to faulty flash.

Example :

The newest (and last) firmware is V3.4.106 Build191009 here : https://www.hikvisioneurope.com/eu/portal/?dir=portal/Technical%20Materials/02%20%20NVR/00%20%20Product%20Firmware/07%20E-series/%5B7600NI-E1%28E2%29%207700NI-E4%5D That's the Linux default start date for when the system time has...

It looks like the flash memory is not being written correctly.

What wiring standard did you use when crimping the connectors on? (eg T568B) Do you mean that the link detect light on the switch is absent on the problem cameras? What is the result of pinging the assigned IP addresses of the cameras?
