Best PTZ Cameras for extreme low light conditions

[low_light]

Hi all,
I am looking for a PTZ camera with at least 60x zoom and at least 2MP resolution. What I want is to use it in moonlight and detect very small objects (2-3 cm) @500m distance. Do you have any suggestions?

You may want to contact the military …

Not gonna happen. These things aren't that good

What exactly are those objects?

PTZ with 60x zoom:

second have IR to 500m.

Here PTZ with 45x zoom but very good 8Mpx 1/1.2" sensor:

EmpireTech PTZ4K45X-AI 1/1.2'' CMOS 8MP 45x 8mm–360mm Vari-Focal PTZ C

1/1.2" 8Megapixel STARVIS CMOS | 45x optical zoom | Ultra light sensitivity | Max. 25/30 fps@4K | Auto-tracking | Perimeter protection | Face detection | Face recognition | Metadata | SMD Plus | IP67 | Dual light fusion | Electronic defog | Wiper

There are also high end thermal PTZ cameras.. they can detect living people/animals up to even 1km (or more) - depending of chosen model and configuration..

Ultra Series - Dahua International

All those are very costly solutions.. You should contact You country Dahua reps to get help with choosing proper solution...

Except we all know rated IR distance is very optimistic. I usually cut rated IR in 1/2 for usable IR

And then there's this
"very small objects (2-3 cm "

 

[Heavyopp]

What exactly are these very small objects?
Do they move?
Are they warm blooded?
Do they have eyes that would reflect?

Yeah and I usually cut that half by another half or more once you speed up the shutter LOL.

And then 2-3cm size objects at 500meters - forget about it.

Thanks for answer. These are all good but the rated IR distances are 250m which is not good enough I think.

I found these two models what do you think?

These are mostly some pieces of metallic/plastic/paper things and does not moving.

the second one from my post had IR to 500m and 60x optical zoom.

the position system is ok - but please remember they can't rotate fully down.. maximum 45 degree down and 90 degree up.. they are mostly to observe objects which are higher...

Last one from hik are exactly the same spec as the third one from empire shop.

I still don't think it will work well at 500 meters for 3cm pieces of metal.

Hmm let me get a 3cm sliver of metal and try it during the day lol. I bet it would be difficult even under ideal conditions.

What is the use case for this and no ability to get a camera closer?

Laser IR is the ONLY way thats going to get close. So you're on the right track.
Of those two, the HiK looks much better as it has the correct sensor size for 8MP. The Dahua is using a 4MP sensor on an 8MP lens

Still dont think you're gonna see 2-3cm things very well
