Your Blink camera comes with a mounting bracket and a screw in the box.

To begin mounting your Blink camera, please remove the back cover of the unit.

Flip over the camera back plate, there is a circular piece of plastic that needs to be removed. All you need to do is press on this piece of plastic from the inside of the back cover.

Once the circular insert has been removed, your back plate should look like this:

At this point, you can reattach the back cover to the camera and then attach the mounting bracket by firmly pressing it until you hear it snap in place.

Use Live View (more information about Live View found here) for this camera. You should hold your camera in the location you plan to install it. Verify that this location will give you a good view of the area you are trying to cover.

The best motion detection occurs when a subject walks across the field of view from one side to another rather than directly toward or away from the camera. Please keep this in mind for optimal motion detection before mounting your camera.

Once you find the optimal location for your camera, screw the mount into place.  Please note, use of the included screw for mounting will create a hole in the wall surface.

Once mounted to the wall, you can rotate the mounting bracket and open and close the hinge to pick the perfect angle for your camera.  If you find that the bracket is loose and causes the camera to not stay in the correct position, you may need to tighten the bracket. There are thumb screws on either side of the hinge. You can hand tighten these or use a small flathead screwdriver to ensure that they are fully tightened.

Use Live View to verify positioning.

When positioning your camera, you want to keep in mind that the best motion detection occurs when a subject walks across the field of view from one side to another rather than directly toward or away from the camera.
