For my long-distance LPR application I need a long zoom lens, like 100 mm. I have a Dahua 4MP box camera with a 60mm lens and I found it isn't quite good enough. All of the CS-mount lenses of ~100mm focal length I have found seem to be intended for old-school standard-def analog cameras, not megapixel class IP cameras.
However I see the PTZ models often have long optical zoom like 20x. One such is the SUNBA601-D20X which is 1080p and features 4.7 - 94 mm lens, that should be long enough. This is a cheaper PTZ than the Dahua models so I'm sure the motor reliability suffers, but I don't actually want PTZ features at all, I would leave it parked at the same angle 100% of the time. Can anyone advise if this camera would be a reasonable choice?
