Yeah, you're on T2 (same as me), which doesn't get any more updates. 5.5.800 is the last official firmware (not sure why you're on 5.5.801). Try it from here - DS-2DF8C842IXS-AELW(T2)

Are you sure it's T5 and not T2? What's your current firmware version? As for hue changes, your SVC might be on or you have heavy packet loss on your network.

1/1.2″ oh my god. this is the largest sensor on a cctv ever.

Can i buy one (or 2) from you please?

Good question. If somebody can find me a 4K PTZ camera with a good sensor and a 50mbps feed, I'll grab it right away. I have a Hikvision 1080p PTZ beach cam - even at 15mbps (maximum possible bitrate and "high" quality) I can see heavy artifacts on waves or crowds during direct sunlight.

it’s not only the bitrate, it’s the compression quality too. Good compression require alot of cpu power which ptz cameras simply do not have. It can be compensated with higher bitrate, but having 16mbps for a proper 4k is simply not enough.

14mbps for 4k? Well that’s a shame. i wonder how bad the compression is on complicated sceneries (like big moving crowds)

Updates?

Can you advise on the price please? And alibaba has them on sale for about $1400 - is it a scam?

According to the sound, you clearly have a ground loop problem. Anyways, this thread is 3 years old. I also had a microphone humming issue (solved): SOLVED: Hikvision microphone static noise/humming which starts right after the boot sequence is done

SOLVED. So the problem was that I was using the same power supply to power the camera AND the microphone. Initially I had only POE and I was hoping that I could use it to power both the camera and microphone (with a POE splitter and a 12v-to-9v adapter). But turns out that is not a good idea...

It's impossible to downgrade from 5.6.0 via tftp/web or serial. There are also no known tools which would allow to modify the firmware headers to let it be downgraded. Trust me, I tried everything. In the end, my problem was solved by Hikvision (they replaced my camera for free) I contacted...

Little update - I hooked up a 9V battery to power the microphone and all the noise is gone. I'll try to get a dedicated 220V-9V adapter for the microphone and see if it works.

I use a unpowered external microphone (Dotworkz KT-MIC) which became powered with the help of this manual that was sent by the microphone manufacturer: So what I'm doing is I'm using a 12V external adapter. The plus (positive) wire is feeding the camera and the microphone (with the help of...

Wow, that's really weird. Why would the amps matter? The mic isn't using that much anyways. Perhaps the first adapter was bad? Do you power the camera from the same adapter?
