I've struggled to get my DS-7608NI-SE/P to work properly over the last couple of years. It now exhibits "freezing" of the signal regularly and needs to be rebooted. Of course this freezing is random and occurs at the most inopportune time. To allow me to resolve this and to add additional...

I've just opened up that Youtube video again and it appears that he has definitely a deeper 20mm fan. Mine for some reason is not a 20mm but 15mm. I have a 7608 NI SE/P but I wouldn't expect the fan size to change within the 7608 model range. Perhaps I'm wrong.

I've just done this. The Noctua fan in my case does NOT fit exactly. I watched that Youtube video on changing out the fan and it looked so simple. When I got my fan it is much thicker than the one I took out. The Jamicon fan I took out was only 15mm deep and there is not enough room to fit the...

I’ve had a similar issue with a new cam that wouldn’t come online with an older model NVR. I had to log into the camera directly and change the authentication to “basic” rather than “digest” and that cured it. The security on the camera was newer than what was available on the old model NVR...

Well that’s my problem. I can’t log on to the camera. It’s visible in SADP and the NVR but when I click onto it in any screen it says it doesn’t exist. When I try to connect via a web browser on either a PC or Mac it can’t find it. When I use the VMS4200 software it sees it but I cannot...

OK I have updated the old camera's firmware to the latest versions as per the procedure previously mentioned and they work OK. The new camera shows up in the SADP tool when directly plugged into the PC. When you try and access it via the web browser, it cannot find the camera. Yes the PC is in...

Given the amount of problems I’ve had and chasing solutions I’ve been to worried to update the cameras I gave that are working in case I lose even more. I might have to do as you suggest. How do you factory default the cameras?

I updated the NVR firmware via the Upgrade process only to Brick my NVR. I was just a blank screen and not doing anything. I downloaded the TFTP program and managed to recover the NVR but at the same time I ran the V3.022 firmware which is the last update for this model. For those who may be...

Thank you. Comprehensive but succinct answer. I will certainly try that.

I have seen somewhere that people say that you have to update firmwares incrementally i.e. each update in chronological release order. Or can you just jump to the latest version?

Thanks for the reply. Tried changing to the stronger password but did not work. When checking the NVR Firmware, it said it was only a V2.2.5 build 150421. The link you gave me to the 2017 update is still newer than mine I think. I believe it is for 7600NI-SE. Mine is a 7608NI-SE/P. I assume the...

Ok. I reset the passwords back to the default. I ran the SADP software attached to my computer and it recognised all the cameras. Connected the cameras to the NVR and all the cameras worked. Yippee! However I have a new problem. I tried to connect a DS-2CD2143GO-I camera to the NVR but no...

Ok. Thanks, I’ll try that and report later. I appreciate the help you have already given me. Thank you!

I haven’t got the NVR with me at present but I think it was a base model like DS-7600 NI? Yes I purchased the NVR at the same time. Maybe they had old stock they were happy to get rid of. Only thing I did however was when I ran the first setup wizard I changed the admin password from 12345...

I purchased the cameras from the security company that installed this identical system at my work premises. Except they used about 16 cameras and a bigger PVR.

Hello. Newbie here. So I have some newbie questions. I am trying to set up a CCTV system which will be used to record events after the event. That is, it is not going to be connected to the internet. I have a peculiar problem at my holiday home (which does not have internet connected), where...
