Among the components included are window and door locks, security cameras, recorders, monitors, motion detectors, security lighting, alarm systems, entry and access systems, related junction boxes, associated wiring and conduit).You need to test whether the costs you incurred bettered, restored or adapted the particular system, not the impact on the building as a whole.When you purchase a building, the building structure and all of the various building systems are depreciated as a unified whole based upon the cost of a building.

Same for necessary repairs....every phone has a camera these days and the better ones link right to Youtube.  

Get a publishers clearing house banner and attach it to your car , show up with a camera and knock on the door ,  When everyone comes out have them on tape ask them their names and then hand them the court papers .

Since it is part of doing business , as soon as I can get one taken that does not break the camera or your monitor, LOL I will get one posted. 

Yep isn’t that nice.Well, we were prepared for that, had attorney write up a Non-trespass order, asked deputy’s to serve him, wish I had a camera to take a pic of his face.Not only had the eviction, now he can’t trespass or I’ll have him arrested.Will post eviction story and lessons on current eviction, wow some of these people have no shame.

Perhaps could install cameras (dummy cameras?)

When hiring an inspector ask if they run a camera down the main line to check for cracks and blockage?

I found them after several bigger companies refused to get dirty when I had a clogged basement drain with no exterior clean-out.I've used them to clear drains, camera the main line, water jet the main line, and then excavate/replace the main line.

I keep a camera in my car and snap a picture of all signs that say "I Buy Homes" or Stop Foreclosure or whatever.

Set up a hidden camera?
