Best security cameras for interior of house with roommates

[Bruce P.]

Hi BP, so over in this post, there were some great suggestions on cameras for outdoor security. But for an interior of the house where you as the owner reside while renting out to roommates ("house hacking") - is there a camera or system anyone can recommend for:

1) Monitoring guests brought over by roommates in the common areas (my friend has a guest policy and cameras would obviously help ensure the policy is adhered to)

2) Potentially helping police identify someone should they break into the house?

Hopefully the system is easy to install and makes it easy to monitor the feeds via your computer or phone. And hopefully it doesn't require too many battery replacements/recharges.

Thank you BP community.
