Install a lockbox outside, install IP cameras inside.

Have you had a plumber come out and do video inspection of the piping or useinfrared camera to determine if there is a leak?

Just uses your camera to map out the walls and create a floorplan automagically.

That’s everything from checking into potential code violations and unpermitted construction, to conducting a camera inspection of the drain or sewer lines if the pipes are old and you suspect they may be deteriorating.Lastly, I understand you may not be familiar with all of these things.

We are pretty sure that the first floor deals drugs and so we want to invest in security cameras to deter them doing business at the house.

I liked the "hand held" camera style of the video.

I tried using a camera mounted to a telescoping pole today to get an idea of what the view would look like.

I would also consider security measures such as cameras and Ring doorbells. 

Should I put up a security camera to show that I'm serious?

If you are using a property management company make sure to tell what kind of tenant you want (FICO, income to rent ratio, section 8[I don't recommend],prior evictions, criminal history[sex offenders], marijuana on property)If your unit is a studio or 1 bedroom you can a lot more money wit Airbnb, most markets now have Airbnb property management that handles all turn-over things such as cleaning, dealing with guest, we use and August Smart lock that sincs with Airbnb so you can see on when they come and leave plus a security camera outside the unit to make sure there is no extra people or a party going at my unit so far we are making more than double from what we use to make on it with a regular tenant.
