Cameras Unresponsive In Extremely Complex Scenes

I have a temporary wireless camera setup which I will deploy for a recurring event every year. It is the largest county fair in Indiana and the scene is very complex at night. There can be over 30,000 visitors, several rides, flashing lights, flags blowing in the wind, and a dark skyline, although more than 90 percent of each scene is occupied with constant motion. The cameras consist of one (1) Axis P3707 Multi-sensor and four (4) Axis Q6055 PTZs. They use Ubiquity Access Points which connect to a Dell (an older loaner model) computer and then run to monitors in a Mobile Command Center approximately 300 feet away via Cat6. There is a PoE Extender at about the 200ft mark. The integrator did not use a VMS for the maiden voyage- due to the last minute request on our part - and instead opted to use browsers for viewing with on board SD cards for recording. The Access Points are all close to line of sight without significant obstructions and showed full signal strength. Each camera had its own AP and there was a single AP at the server. We later added a second AP at the server to split the bandwidth, with no improvement in performance. The cameras display very little latency during the daytime (when motion is limited) with just a little more at night when motion is nonstop. However, controlling the PTZs at night is nearly impossible as they can take up to 20 seconds to respond - especially on the camera furthest away from the main access point (400 ft). Due to the scenes being completely occupied with motion and the scene complexity, I doubt that any Smart Codec adjustments will have any impact, but I've tried adjusting everything from frame rate, to compression, to I frame interval to no avail. Sharpness adjustments also failed to correct the issue. The system actually seemed more responsive in MJPEG, but that may have been a fluke as it seemed to be fine one minute and then perform terribly as soon as my boss showed up to view the system or we were looking for a missing child. These cameras need to be responsive when children (frequently) get lost in such a large crowd or we are tracking criminal activity from camera to camera. THe intention is to eventually rely on analytics to speed up these searches, but we are no where near that at this point. Have we exceeded the ability of wireless in this case or could it be an under-powered server that can't compute fast enough to keep up? I have time to cable the project this year, but it was set up on two-weeks notice last year so wireless was the only option. I would, however, like to continue to test the wireless concept as we are considering building mobile units for critical incidents in the future. I will be adding several 2-5mp cameras to the system via cat6 and running it on an Avigilon VMS once we work the bugs out this year. Any suggestions or advice is much appreciated.
