The interwebs will only give you part of the story in a world where Photoshop use and wide-angle real estate camera lenses are widespread.

The physical work part involves cleaning out units after people leave (and leave trash), mowing the grass, maintaining the fence and security cameras if you have them, over-locking unpaid units, conducting auctions to enforce your lien. 

The only method obvious to me is setting up a camera. 

, truck to load it (later I bought a trailer), good camera (iphone can work too), Drone (nothing shoots land better than aerial pics and vids), marketing budget, rubber boots ( good for swamps and cold weather snow), rain gear, bug proof clothing, Sawyers brand repellent, a good hat, marketing material, letter head, computer, printer, filing cabinet, RE license, certifications. 

If your camera has a wide-angle lens, you can typically capture an entire room with 2-3 pictures and then some detailed shots for specific items like window glass.

For BPOs you will want a good digital camera with a decent zoom.

I'm taking my camera to take photos/videos of the property so I can market it.

Of course she says it just happened and water was on the floor.I hope its something easy and does not require cutting pipes etc..I am going back this afternoon with a camera.

I have security camera systems on the buildings and we thoroughly screen all tenants.

Digital cameras typically save in the JPEG format, so usually there is no need for conversion of camera files.Once you have a file that is saved in JPEG format, you can try the upload to BP part of the process.
