Does he want/need to ability to invoice and grant access to individual cameras?
My dad has a giant bullet camera with integrated IR ring pointed at a nest of sparrows outside his window. The IR ring attracts bugs for them to eat at night. My dad is proud of this setup, because I get snapshots frequently emailed to me of birds doing bird stuff in the nest.
I think he uses a cheap IP camera, DDNS, and his home wifi router for this. No special equipment needed.
How about an MX S15D?
Dual camera capacity, lots of lens options, nice video/audio capture and free operational software.
Plus it's a nice POE power load should they be doing remote nesting captures.
VIVOTEK FD8152V should do the job. It's very small, supreme low-lux visibility, vandal-proof, wide angle(102°@F2 or 69°@F4 model) and built-in IR.
