I've just tried the latest V3 (3.4.109) for the model but just get the same result - frozen at 'booting the kernel'. I've installed so many Hik NVRs in the last 10 years and never had a failure (other than PSUs) so this is the first time I've had to resort to flashing the firmware this way.

I've gone straight to the latest for that model which is 4.74.205_230712.dav. I can't be sure what firmware was on it previously as it's been sat unused for some time. At a guess it may have been an early V4 but could even have been back on the old V3. Is it worth trying an older version...

I'm struggling to recover a DS-7608NI-K2/8P. After some initial issues being unable to get the firmware on via TFTP (I'm using a Mac with parallels), I finally managed to get the transfer to complete and got the prompt to reboot. However the recorder still does not boot. It's not pingable and...

Thanks @steve1225 - I'll take a look through those links. Yeah I found that surprising. The Hikvision ColorVu 4MP/8MP have 1/1.8" and 1/1.2" sensors respectively. Their G2H ColorVu hybrid share the same 1/1.8" sensor for both 4 and 8MP models. I was surprised to see that the 8MP Dahua...

Yeah I've been through that already and it looks as though some models discussed on this forum re not available in the UK. I'm waiting on a couple of official suppliers to approve trade accounts. I could probably do with a model number decoder document if such a thing exists. For Hik I can...

I've been an installer of Hikvision cameras for around 10 years now. Hikvision is far more popular than Dahua in the UK and therefore there are more approved suppliers for installers. I'm thinking of trying out Dahua models that would be considered the nearest equivalent to what I use...

You're locked out of the cameras because they were using plug and play on the previous NVR and when you've replaced the NVR you've possibly used a different NVR admin or channel default password. When switching cameras or NVR I prefer to manually assign addresses to the cameras. In your case...

My guess is that it's a current technical limitation. The Hybrid light models use a new lens design with 'super confocal' technology. The focus point for visible light and infra red light are different and the lens has been designed to counter this focus shift by reducing optical light...

For the 4MP Hybrid light vs 4MP Colorvu, I'd choose the Hybrid light version as both 4MP versions share the 1/1.8" sensor (except if strobe light/speaker were needed as the Hybrid light model doesn't have a Live Guard variant (at least not yet in the UK) A more difficult choice for the 8MP...

I've had one installed for a couple of months (DS-2CD2387G2H-LIU). I only became aware of the smaller sensor size (1/1.8" as opposed to 1/1.2" on the 8MP ColorVu) after I installed it. I find the image much sharper in IR mode than the camera it replaced (an old Ultra series DS-2CD5A46G0-IZHS)...

Try updating to the latest version of iVMS-4200 (3.10.0.6) as the release notes mention the following in the bugs fixed: "When dragging the timeline bar for playback, the playback image disappears, and the prompt pops up: Incorrect calling order"

Yeah that's my comment. That slide comes from Hikvisions HCSA course and was out of date already when the course was presented 1 line: DS-2CD1xxxx are value series 2 line: DS2CD2xxxx are pro series 3 line: DS2CD3xxxx are ultra series (Hikvision were previously calling these 'core solutions'...

Yeah I already had node-red set up to link my alarm system zones to my Hubitat hub using MQTT. Last night after a long time messing I found the 'Hikvision Ultimate' palette and added that to node-red. That has an xml node and once you've configured the authentication you can just paste the xml...

Yes I've got the scene switching back and forth using postman and now have to figure out how to implement that in node-red. When I'm sending using postman, I can see (using Proxyman) that initially the camera sends a 401 connection refused, then postman is resubmitting using this setting: "By...
