I created a new thread a week or so back not realising this one was here, and thought I'd throw my 2p into this mix here.
I installed a hikvision system 7 years back, and it worked fine. The software was clunky, but it seemed to be doing its thing. Where it all went wrong was two years back I went to get some footage and found I'd lost all the passwords for the NVR. So I reset it.
Big mistake, that reset of the NVR worked fine, but then it didnt reset the cameras and they stopped liking each other. So for 2 years, I've had a NVR not recording, and access to the live cameras only.
Our local area has had a rise in problems since one particular neighbour moved in - blatant drug deals in the street, noise and arguments that escalate, police called on a regular basis [and then they come knocking for footage, "yeah, sorry, none of it works!"], vehicle breakins and suspicious activity - so I've looked to tackle the camera problem again.
The reset process for hikvision and hilook cameras isnt easy, but it can work.
Two of the cameras when dismantled had a reset button in them - press and hold the button for 30 seconds with a power-off, power-on. these can then be detected easily and reactivated.
If you don't have a button [two didnt], then you need to use the SADP tool from hikvision, and have them on your local network - If you've got an NVR, and your cameras are hooked upto that and not your home network - get a PoE switch and hang them off that instead. Dont reboot your machine running SADP, or think "maybe I'll use the SADP tool on my phone instead of that laptop that was doing it..." as it seems each load of SADP creates a unique ref or something that doesnt work with another load.
Once you have them on your local network and can see them as devices in SADP, don't close the SADP tool, don't power cycle cameras, and complete the password reset process with your UK distributor [or in my case with Hikvision UK support] within business hours.
You send them an XML or a QR code and some kind of proof of ownership, they send you back a XML. Sometimes it works first time, sometimes.. you need to redo it over.
There were a few times over the last week where I was looking at just buying Ring cameras and binning off the Hikvision due to the complexity of the processes and the software, but I got to this and am happy now;
My next job is to reinstate the NVR, but I will be leaving the cameras on the local network this time.
And then next weekend I'd like to do something about the nightime view of the driveway cam which often looks as bad as this;
So I'm going to get an IR floodlight and try that out.
