Understand. Which do you personally recommend?

Some things to think about:

It can’t be totally wireless, unless as you say you’re considering solar + battery. You have to have a power source.
Do you need an outdoor-capable camera, or is indoor-only OK?
Most Wi-Fi isn’t good beyond about 100 ft. Will that work, or do you need special antennas or wired ethernet?
