We plan on going back when it warms up and will bring the 35mm camera then too.Go to visitoakpark.com and order the free guide.

We have smart phones with cameras and video, use them.

Bring a camera and at least one witness.

Try sprucing it a little bit, try painting the door with another contrasting color and take some of that color to the A-shaped roof border facing the camera in picture on on Zillow.

Does anyone have any experience with installing security cameras at homes?

Don't use your phone camera if you can help it.

If you absolutely cannot get access and you feel the child is alone, at some point you're option may be to see if law enforcement can escort you into the home or bring a witness who can use a camera or smartphone to video record the entry from start to finish.

We’ve got access to top of the line technology to help sell homes including virtual walkthrough cameras, 3D home modeling software and birds eye view video and photography via drone.
