Speaking from experience, by far the best audio I've obtained is by using one of Hikvision's powered external microphones. That camera you linked has a microphone input, so you could add one. The model is Hikvision DS-2FP2020 Hi-Fi Microphone- DS-2FP2020#NA it requires 12VDC power to operate. If...

Note the "up to 60m"- in my experience (with various Hik cameras) the reality is it won't reach anywhere close to the rated "up to" distance.

I posted that suggestion as I had exactly your problem happen when configuring my 7616NI-M2

It's likely you need to configure the Liveview page by adding what cameras you want displayed to each "box".

I tested the temperature difference with and without that fan running tonight. The first temp is with the fan running, and then the second with it removed and checked 1hr 20min later for the no fan temp. I removed the entire 3D printed fan assembly from the bottom of the case to make sure it...

Check out the specs for "Incoming Bandwidth" on the NVR models and divide that by the number of camera inputs to get the bandwidth per camera. I too had the 7608NI-I2/8P and it only has 10Mbps bandwidth per channel - which is too low IMHO for 8MP cameras. The 8MP Colorvus I've got seemed to be...

Thanks. I didn't pick up it wasn't an IP camera model- I just went straight to the light sensitivity specs. I'd be hoping those HDTVi models are substantially cheaper? Hikvision seriously need to stop using the "Colorvu" and "powered by Darkfighter" labels on cameras that don't perform well in...

There's also a fan type vent hole on side of the NVR where the power supply is (IIRC) - so another fan exhausting the hot air fitted there would help drag cool air in through the holes in the base under the hard drives. I'd also suggest fitting higher feet under the NVR if you have it sitting...

The minimum illumination specs for those cameras should tell you the problem: Camera Image Sensor4K CMOS Max. Resolution3840 (H) × 2160 (V) Min. Illumination0.01 Lux @ (F1.6, AGC ON), 0 Lux with IR (compare the above specs to Colorvu or proper Darkfighter cameras) Put bluntly that's woeful...

I changed both fans in my old 7608NI-I2/8P (or a part number very similar to that..) When I updated to the 7616NI-M2/16P it was immediately evident that the OEM fans weren't as loud as what came on my old 7608NI-I2 NVR. So I haven't bothered swapping the Noctua's into the 7616 M2 yet. One thing...

An update- someone in a black tracksuit kindly walked up the street late at night yesterday. They were in the poorest lit area and walking on the black road. There was a definite improvement regarding the ghostly smudged imaging. There was virtually none until the light got so dim the person had...

There's AliExpress and Ebay too. But you need to do your research, and take the risk of zero support and no warranty.

It's strange they don't have a UK presence? From being on IPcamtalk, they seem to be ahead of Hikvision for features rather than behind. They're certainly the favoured brand on there.

This is from a conversation on IPTalk, with a retailer who used to sell both brands. It was back in 2022, discussing a large jump when adjusting the HLC setting with the 4K G2 Colorvu I'd just purchased. (They still do it on the latest firmware.) He's since stopped selling Hikvision and only...

I can't remember for certain, but I think I checked inside the M when I fitted the HDD. It was completely missing the IR side of things - with no IR receiver inside behind the front panel. It's rack mounted (and a pain to get out) or I'd check again to be sure.

Ahh, yes the ghostly people on the screen- I have that too. I'll try your codec suggestion- thanks for the tip. I've got basically zero street lighting and what there is (two houses either side of me on the opposite side of the street have one) is very low intensity and mostly blocked by trees...

On another forum someone with one was saying they could only get theirs to work with a limited number of 4K cameras? Not all the channels. I asked what the problem was but didn't get a response. I have noticed mine can have issues with the channel data rate set to the maximum 16Mbps for each...

The remote doesn't work - I have the 7608NI remote signals programmed into a Logitech remote. I tried it just after getting the M and there's no response. I'll have to take another look at the alarm settings on mine. I normally have the loss of video signal (etc.) set to the audible alarm.

Make sure you read through the various threads that discuss the firmware issues with some of Hikvision's latest NVR's and cameras. I "upgraded" from a 7608NI-I2/8P to the 16 channel M series a couple of months ago, and they've removed some features. The old one came with an IR remote control...

It has got me pondering (again) why I keep buying Hikvision equipment. The slow exposure time doesn't explain why the writing on that sign was completely missed by the G2. Edit: Actually, looking at the G2 picture again the highlights are over exposed compared to the G3. That would explain the...
