Specs of FIT0819 endoscopic camera

Hi,

I am writing in behalf of a university project that is looking for a suitable endoscopic camera and we found the FIT0819 “3-in-1 Waterproof USB Endoscope Inspection Camera”. Unfortunately, the provided specs do not provide the following:

 - Focal length

 - Working distance (working focal length)

 - Frame rate (and is frame rate dependant on resolution?)

 - Any required software?

 - Operating temperature (nice to know, not necessary)

Can you please provide these specs?

Thanks,

Siim
