Keep in mind your only looking at this via the image at one specific time of day. You need to look at this issue and how the lighting will change 24/7/365. Morning and end of the day tend to be the harsest in these parking decks. True WDR camera are very important for these applications.
^^ What M.M. said.
And, do the cameras lie on a North-South or East-West Axis? If the end of the shot is open to the horizon the glare may be quite intense on a E-W orientation.
Btw, what is this device:
Camera, Illuminator, Car counter, LPR? Is it running 3-phase? ;)
So I am going to say that even if there are far worse parking garage lighting scenarios than this one, anytime you have half the scene lit from within and the other half lit from the outside, it just begs for true-Wdr.
And prices have come down quite a bit as well. For instance check out this HD-CVI FLIR (Dahua) for under $100 bucks, reviewed by IPVM here.
1080P IR True WDR.
If you are prefer domes or IP cameras there are some cheaper, if not as cheap as this one, true WDR models available from the usual suspects.
"Price for True WDR is the customers main concern."
1, as 2 mentioned, there are a number of true WDR low-cost cameras. Here is a list of 30+ True WDR cameras under $300. Take a look at that and see if any models make sense for you.
I do think true WDR will help and if you can get it at close to the same price with one of these low cost options it is worth considering.
Note: True WDR has gotten less expensive as multi-exposure has more broadly been built into imagers.
