Hello, Does anyone know any 5MP PTZ camera with 36x optical zoom and 12x digital zoom?
5MP PTZ With 36x Optical Zoom Camera
NO.
Presumably you mean a speeddome, not a fixed camera on a pan / tilt positioner, correct?
I am going to bet a dollar that undisclosed is responding to a bid/RFP that requires this specification.
Unfortunately, I think this is a Frankenstein spec where the writer combined the individual attributes of many different cameras.
Yes you are right, this is part of RFP specifications which also specify a 5MP fixed camera with 40X optical zoom. I can't find any vendor providing such cameras. Any advise?
This made me asking what is the technical limitation of MP cameras in terms of the optical zoom? Also, why there is no PTZ camera with 5MP?
You can put a 5MP fixed camera on a pan tilt positioner. There are a few 5MP cameras with integrated zooms, like the old Axis Q1755 (10x) and the new Avigilon bullets (3x).
But 36x optical on a 5MP. That means a lens that varies from say 3 to 108mm focal length, which I do not believe anyone has at that resolution for a C/CS mount camera.
can anyone share the RFP?
I did some basic translation since the orginal document is not in English language

So it's a 5MP 36 optical zoom PTZ and they want built in integrated IR that goes 40 meters? Then throw in a P iris lens?
This is a type of spec where I would love to speak to the person who wrote this. It's as they read a couple of websites and just threw a bunch of things together that they heard were good.
May we have an article explaining the technical limitation of the MP cameras in terms of FPS and optical zoom. Thanks
I am not sure we can write something full length for an article. It comes down to things:
- It is costly / complex to build very high resolution, very long range varifocal lenses. The 'biggest' I know of the new market is Tamron's recent HD motorized zoom lens which supports 1080p at 30x optical zoom. Impressive specs but not 5MP / 36x optical.
- For fps, it's an issue of encoder chips supporting (processing power, etc.). It takes a lot to encode high resolution, high frame rates. 1080p/30fps is now commonplace but, as others mentioned, 5MP maxes at 12fps/15fps H.264 for current cameras. This will change. For instance, the recent Ambarella chips, which are empowering 4K cameras will support 8MP/30fps. That said, chips like that will take a few years to be widely available in surveillance cameras.
I found the following camera which supports full HD and 30x optical zoom
Yes and Pelco has a recent full HD / 30x optical zoom. You could take 2 of them and tape them together to meet this magic specification.
Anyone knew of something better than the full HD 30x optical zoom and light? The SW598 has an indoor version SC588. We recently briefly tested the SW598. Still on a look out for someting better.
