Re: Underwater inspection camera
HD isn't 1920. Its 1920 wide, but nobody uses that. Its 1080p high. So yes, this is a standard def, but lots of dedicated inspection type cams are still standard def.
But in either case, its PAL, avoid it.
Yes, HD is 1080 Vertical by 1920 Horizontal. (Digital)
This camera is PAL. 625 Vertical (Defined by the PAL standard) by 420 Horizontal Resolution. (Analog)
While it is a very good analog camera, it will be far from impressive once you are used to seeing HD.
It will best be compared to a quality security camera.
The field of view of any optic system underwater with a flat air/water interface is reduced by about 2/3rds.
Quality underwater cameras ($$$) use a hemispherical glass dome ($$$) over the lens to prevent this optical distortion.
That is why fish in a aquarium always look closer and larger than they actually are.
Considering the water clarity in the typical harbor, the camera will need to be within one foot of the hull to see much of anything.
A wide angle lens will image ~6-9 inch square of the hull at that range.
If the inspection is looking for anything specific it will take a long time to look at everything.
If you just need to get a general assessment of the hull, e.g. what the Barnacle density looks like, it may be OK.
