Camera security system

[Michael K.]

Hi all - wondering if anyone has any recommendations on camera systems/brand/manufacturer for a small 6-unit Multifamily property. I can't use Nest cams because I would need a modem and wifi connection in the building. Wondering if any other solutions out there that will allow me to see what's going on at the building from my smartphone and record for security purposes! Any suggestions are greatly appreciated! Thank you!
