It only takes a few key relationships to get things in motion. 

I already have eave mount motion sensing dawn to dusk security lights at each corner but she still feel better with the light directly over the doors.She pays for her own electric so I am not paying for the usage.I read that leaving lights on forever can be a fire hazard but I don't know if that's a myth, or not.The lights are enclosed, ceiling mount lights with a 60W incandescent bulb.

If there’s a lot of motion at the door at late night, I check them.         

They claimed she was part of the scheme.By documents, testimony & documenting many false statements he made that were provably false, (interrogatories, depositions, motions, and witnesses) and by perseverance I finally won at trial.

We just installed 2 dehumidifiers with condensate pumps installed so water is being plumbed out of the house at all times through this condensate pump. 

When I rehabbed the laundry/mud room I installed a ceiling light with a motion sensor built into the fixture.

I think he was two or three months behind on rent.We found out the landlord filed a motion to evict everyone from the home.

@Aref ShehadehYes and then you could leave it there if you wanted as a secondary source of heat/air/dehumidifier

I figure, if I'm at least going through the motions of buying an investment property if one jumps up and bite me I will be ready.

If they can't serve the tenant, then you can ask for a motion to post from the court.
