The very wide 50mm F1.8 photography lens and aperture is exceptional in very low light conditions and walks all over any system using a CCTV lens. It is so responsive that it can frequently be used with NO illuminator at subsonic ranges and sometimes at several hundred yards.
Price is £290 for the spotter alone - or £330 with an IR illuminator and mount.
It is also listed on ebay and FB. Some of the photo's are stock one's but they have all made the same.
The spotter is custom made to take this type of 5" monitor....
...Which can be re-located to inside a vehicle with an extension cable - available separately. This one is shown with a DVR velcro'd to the pod and fed via an inline 'Y' lead :
This is how you access the battery compartment:

I assess this type of rig by how well it sees without artificial illumination.
These videos are a fair appraisal of how you can expect it to perform. The image seen on the small monitor is many times clearer than the compressed and uploaded to youtube video that you see, you will get a slightly better idea if you minimise your page to about half screen to get a smaller player:
The first is approaching the worst ambient light conditions you are likely to find where it will still see something at air rifle range without assistance. If there is even less light you will see nothing at all without an illuminator.

This compares to about the very best you will see from it in patchy cloud and good light conditions, but it was made with a slightly better and longer focal length lens:

This is an advantage it can give you in foggy conditions:
