While surfing online I came across an article http://protectionplus.ca/blog/what-are-the-legal-requirements-for-installing-cctv-cameras/ and it points out the things that should be taken care off while buying a security cam.

We have installed 16 wireless security cameras on all of our properties.

I am not that much interested in the camera.

Do you use an off the shelf camera?

Some fencing, good security system with cameras and link to local law enforcement, and gravel to mark your spaces.

You could have one at each site, attach a camera/mic/speaker to it and fly around to check on work.

I have the back up camera with zone control, leather seats with all pressure controls for the back and legs, heated seats with dual zone from warm to hot, center console radio with steering wheel control.

In my experience, plumbers and drain services that have cameras can help you locate the problem, but equipment to cut up the roots inside the pipe (run by people you hire or rented by you) seldom does the job.

Just install dummy security cameras and a good lock.

Cell phone, cameras, boots, ladders, tool kit, mold collection kits, computer to type and email reports, and grit.
