You gotta see this Mini 4MP Auto-Tracking PTZ

Thanks, I did track it down to the Hik but was unable to find any night video. Wondering about the IR reflection with the dome.

Hik also has a 4x zoom darkfighter version that I imagine does a lot better at night, but 4x isn't a lot of zoom.

The 25x small PTZ caught my eye.
I have the dahua mini PTZ and the zoom is pretty weak, I don't use the IR on it because there is plenty of light where it's at,I did install one in a dark location and the IR reflection was very bad.
I would like to see dahua release a new small PTZ with IR, their ceiling mount ones don't work for me.

This camera has some really nice low light specs

The reflection minimized because of the IR is separated from the lens.

Could I make a suggestion to feed back to Hikvision?

You demonstrated how the video is smoother at 60fps than 30fps (to be expected) but you lose the resolution. Assuming the sensor / chipset isn't capable of 4K @ 60fps in a firmware update to come later, could I suggest that Hikvision consider using a software setting that gives the option for the software to vary the resolution on an event trigger? eg. The camera would be @1080P 30fps when just moving between presets and scanning the area. However, on detecting the crossing of a line or an intrusion into a zone (if it has zones) then the camera software changes the resolution to 4K @ 30fps upon commencing the object tracking. This would give the best of both worlds for the penalty of a momentary loss of recording as the resolution switched. Software wise, it could be an option so you could choose to use it or not.

Lol 60 and even 30 fps is overkill waste of resources. What's the point of higher fps when there is no motion!

I'm guessing if you're deploying it as he has done to monitor a large yard or driveway, then there will be motion as the person / vehicle comes across the yard / along driveway. I take your point though about other circumstances.

This is possible using Hikvision NVRs. You can set some of the Main Stream (Event) settings separately from the Main Stream (Normal) settings. Although the camera doesn't do 4K and the resolution cannot be changed after an event trigger, the frame rate and bit rate can.

Maybe a feedback request for Blu Iris then if it doesn't already support this. The ability to change resolution as well would be even better.
