Pvc pipe in concrete was not wrapped in the concrete.Slab, they need to saw cut and then jack hammer il the slab.Plumber will stick a camera down to check.Good luck.

None of these methods are foolproof, but if you go this route you are aiming to make it more trouble than it's worth.Eyes on the unit: hire security to patrol the house; put up monitored cameras; put up cameras with motion-detection alerting; ask the neighbors to watch; station a guard dog at the unit (not recommended). 

I contacted a few plumbers and they all said there's no camera small enough to do that.

Maybe I just operate in a non nanny state where it's assumed parents will keep their kids from eating paint chips

Lots of building activity around Houston.That's a nice looking camera you have on your shoulder.

I use a FLIR thermal camera on every inspection.  

I am going to get my girlfriend's camera to take a headshot of myself and then update my profile.

It also lets you create and upload PDF's directly from your camera - this is a feature of many paid stand-alone apps, btw. 

The nice thing about these vs. window units is you can pull the exhaust tubes out of the window each night an secure the property.Also I would suggest adding a fake or real camera system with sign.  

Hey there Eric Benzenhoefer, I can share a good contractor with you tomorrow when we meet, I will share here that how I started out with him so I didn't take too much of his time, and I still do this.... was I hit the streets with the wholesalers that are cranking out the deals in the email blasts, and I would walk the property with my video camera, or my iphone camera, then I would load to my laptop while I was driving to one of his jobs, and then took only five minutes of his time to go over every detail, then if it made sense to him, he would get over to the property again, or I would drive him to it, so his office was mobile, and this has worked out very well for us both!
