Expensive is relative, what about a Mobotix S15 with two 180 sensors.
Check out the Axis F44 unit which you can connect up to 4 cameras and use 2 SD cards for storage.

Thanks for the input guys. What I really need is more info on low light abilities for a given sensor unit. And I am aware that manufacturer specs can be misleading at best.
Looking at the Mobotix S15, it seems like I am forced into B/W mode all the time if I want acceptable night time ability. That seems like a bad trade off. I don't mind B/W for low light scenes, but in daylight, I should be able to get color, no?
As for the Axis unit, it seems very nice. The ability to support four sensors is nice. Of course the zipstream is nice too. My only worry here is the low light rating is only 0.3lx (ƒ/2.0, 113° HAOV) for color mode. Axis doesn't seem to offer a low light or integrated IR model. If someone has working knowledge of the AXIS F1005-E Sensor Unit and can verify that its low light abilities would be more capable than their specs imply, please let me know.
I am also, of course, looking into the Hikvision DS-2CD6412FWD-C2 unit with the DS-2CD6412FWD-L30 2.8mm sensor, which is rated down to 0.04lx (ƒ/2.0, 92.5° HAOV). The trade off here is it is only 720p/1.3MP. The main advantage being that it is less expensive than the Axis and Mobotix offerings, has a 4 year warranty, and has software that I am familiar with.
Faris, if you could give me some model number to look into with Geovision, I would appreciate it. I have looked, but could only find their mobile NVR, which has got to be very expensive, since it is an i5 8GB RAM 1TB SSD etc. I just need a simpler device, like the Mobotix, Axis, or Hikvision offerings. I really only need to support up to two >90° cameras/sensors. 180° would be great, as long as low light abilities aren't greatly diminished.
So I have been looking into this for the place I work at. we have a tone of fleet vehicles that Management wanted at least a dash cam in the vehicle but not one the driver could tamper with.
While low light is important in doing some of the testing I found out that while having IR or super low light capability was nice when a car pulled up or drove by it threw the camera into a focus fit or would blur out completely when a car with a full LED fog lights and ultra bright headlights would come by.
we tested four models and the only one that worth anything picture quality wise is all situations was the Panasonic WV-SB131M . the others were Samsungs/Hanwha SNB-6011, and two amazon specials that are not worth mentioning(Management googled them and saw the super low price of $60)
Samsung did great during the day and at night if there was a decent amount of light. the Panasonic one performed great during all conditions including headlight blur. But it cost about $750 for 1080p and $550 720p. it not cheap like the rest of Panasonic's stuff.
If you find something better and cheaper let me know this is one of those back burner projects I have .
Take a look at Drivers ProTec - this was started by a friend of mine who was a long-haul trucker and also got big into CCTV for his off-the-grid home, and later for some of his trucking customers. He looked all over for a suitable all-around camera system for his truck, and ended up putting some systems together himself to suit his exact needs.
I know this is not something you can make money on but if you take video with this and watch it back on VR, it is the ultimate solution for this guy.
I follow your posts John D and I know you're a techyy. If you have not tried it, give it a try
Not to turn this thread away from Jon's needs, but this article provides answers to some questions I asked last August in my post, "Using IP Cameras And An NVR On a Semi Tractor And Trailer."
Thank you for getting the answers for me, Jon. :-) I will have to learn from you how to ask questions!
The reply mentioning Drivers Pro-Tec shows I was headed in the correct direction. Thank you for that, Matt. Rather than mount cameras looking backwards on the rear-view mirrors, I am planning on mounting them on the front end of the trailer -- that way I can see where the back end of the trailer is when I am backing without a spotter.
I still need to look at the replies with videos in detail. Thank you all for them.

Having done this on a semi in the past, vibration will be a big concern, but not in the way that you think. Back then there were not many off the shelf options for mobile solutions so we built our own. We went through several iterations to find a solution that had any longevity. Cameras would fail due to vibration, water gets in places you wouldn't imagine, etc. We ended up settings on an analog solution using a repurposed RV camera with video encoders and and remote recording solution over cellular and a wired weather proof milspec connection to the trailer for those cameras. We built several prototypes and the project died after about a year. I imagine newer cameras designed for mobile applications will be less sensetive, but still, keep that in mind and do one, then run it for several weeks before committing to the whole fleet.
