I would recommend it always, even if you buy outside of Akron proper and have to pay $240 to have a camera run through it.

We collect the mail at the Post Office and then drive a mere three blocks to our Credit Union where we open the mail within the security presence of CU cameras/tellers and deposit the rents into our account.

This was in light of a discussion I had regarding a "high tech" keypad lock and cameras a tenant wanted installed in a rougher neighborhood. 

If you have to staff a motel for check in / check out / surveillance etc.

Security cameras.

My property is pretty well seasoned and I only need to visit once every few weeks and also monitor the property via security cameras from home.

Invest in a good camera and take exceptional pictures of the houses you list.

(We will camera the daylights out of these as well, so we can see what's going on from anywhere.)

The app i use on my phone the most is the camera. 

The sink and tub clogged up again on that day, so I called the city, they came out that day and ran a camera and found that it was clogged on their side, the next 4 days they dug up the side walk, my yard and the street, replaced the pipe on their side and fixed everything.
