After the second snaking of the drain I had the drain guys run a camera and they diagnosed the problem to be a poorly pitched pipe which is causing waste to build up etc. 

What about a digital camera to pick pictures of the property?

maybe they can record using a webcam or any digital camera convert it to avi for online use?

Most big property management Companies use cheap disposable camera's.

We have nailed guys dumping before, but this has emphasized my need to get another security camera installed along our driveway to catch good video of all the vehicles driving on and off the property so I can get license plate numbers.The camera equipment is on order and should be installed next weekend.

Do you have your lights on a timer or maybe even a fake camera?  

They have many cameras pointed at it.

I'm hoping for someone that has good equipment such as snake camera, etc in order to see if we can't figure out a way to fix the problem without digging up the pipes.

At the time everything is in my head, but I found that after a long day of previewing and trying to gather and collect my thoughts, that everything is a mess filled with bad photos angle, even worse videos of me running from room to room with the camera pointed to the ground or the realtor's butt, and illegible notes that seem meaningless afterwards, or even no notes bc it was all in my head at the time..
