Home Security Camera's recommendation

I have an old Arlo system (3 cameras @ $600?) and while its nice to be notified that someone is on the premises, a hoodie and the usual looking modern mask would obscure any identity. I can speak through the camera through my phone and can hit an 'oh ****' button that sounds an alarm. I see that 'Ring' unit a lot on new builds. Sometimes a few signs (smile, your on camera!) strategically placed will add to the 'you are being watched' factor, but the brazen and man with a mission really doesnt care. A 'protected by Smith and Wesson' sign on the house, coupled with a 'keep honking Im re-loading' sticker on the car, might have the same results.

EDIT...if you do get a camera system, you could ask her to have it linked to your phone as well so there are two sets of eyes on the house. You might be more vigilant than her.
