You figure out what your needs are; 4 doors, good safety record, must have backup camera, and under $40k. 

This includes the processing of the periodic payments along with account surveillance to ensure the obligations created under the security instrument (mortgage/dot) and note are being met.  

Saying a "retail investigator" to me, is the guard at the department store watching the cameras and through one way mirrors for shoplifters.

Are they from a camera on your phone or do you have a friend that takes good photos (Like AirBnb photos)?  

I kind of like inspecting houses - I am even going to buy a infrared camera I think - so looking at 40 houses to buy 4 with loans is not that much of a bad thing.

A significant number of the pictures (starting with 2 and 3, and including ALL the bathroom pics) can be improved with better attention to camera positioning. 2 and 3 serve nearly no purpose other than to show this is a LARGE house with uniform flooring and great natural light.

This plumbers manager/owner came and used a camera to determine it was a break/collapsed line. 

Maybe some cameras - though that may set you up for more headaches.

Avoid using your phone’s camera and spring for either a nice digital camera or spend a little extra and hire a photographer to take professional photos you can then use in your marketing.

Great at night, too.AirBNB requires you to disclose that you have surveillance on the property, but I know of owners that have successfully used their video as evidence to support claims against guests.
