Sell wifi to tenants & install security cameras,smart locks, and other wifi monitoring devices.

[Michael C.]

What's the best way to bring wifi to my building so set up security cameras and fire alarm to the network? At the same time, I'd like to offer 'free' wifi as an amenity to my tenants. Currently, the fire alarm runs on two hard phone lines. However, it's wifi capable. I would also consider getting some smart key door locks for common areas and possible get a card operating laundry machine instead of my current quarter collecting system. I have a 5 unit apartment building. Need advice on hardware, software, or a vender who specializes in this. Thanks,
