I've written about our SimpliSafe system and our Night Owl DVR camera system.

Each of them costing ~$300, not fixing the issue and leaving me with a quote of $3k - $12k.. above all came and diagnosed (with the camera) for $150, offered to clear the problem for $50, offered an "after" video of the lines to prove what they had done and offered to come back out any time to offer a free evaluation of what needs to be done on a major scale.

In all seriousness though have you considered a smart lock only the tenants are able to use also some security cameras

She had to buy a camera recently to try to figure out which dog is peeing on the carpet in her current home.

We are considering having portable security camera's on our job sites. 

Do I need a professional camera?

I am assuming that the downstairs tenant may have a problem with the camera being there.

@James Wise Couldn't you use cameras to mitigate that risk?

I could have it checked with cameras for $1000 but I do not want to spend another 1k in, inspections.
