Home Security Camera's recommendation

Mom still refuses to move out of Cleveland. Several friends i went to school with are Police Officers and they state they are just plain old overwhelmed. Guy across the street is selling drugs. She has taken pictures of the cars, buyers/seller. She's been in numerous verbal altercations with them. She talked to Counselman Kelley who is running for Mayor. Detectives. Friday she went down to see the prosecutor. No luck.

(And she yells at me for not getting the covid shot...says covid will kill me. smh)

Any recommendations on home security camera's. A friend recommended Speco.
I'm leaning toward reolink. 4k camera...speco $300ish Reolink just over a 100.

10 years ago i installed a zmodo system. with a 1tb seagate hard drive....$300. Worked good, picture quality was ok. Hard drive crashed a year ago. I thought about just putting a new hard drive in but she needs a better quality picture.
Costco has a really nice system go online and check it out
