In this particular instance I'd get the customer to provide the kit or expense the equivalent kit to do the job (hardware, software etc.) and have them pick it up. They'd pay a top whack rate for the work too, mainly because it'd be what it costs to work their way rather than mine and I'd need to factor in costs for dealing with the requests I'd expect them to make.

If at the end of the day the customer can deal with that, then I'd accept it. I can isolate all my resources specific to that customer, provide them with dedicated kit (presumably with enough storage for them to keep the video footage) and they're (hopefully) happy with what I've done.
