Where you place your Blink camera helps you get the images and video you want.
To observe a place, mount the camera and use the Blink app to test your placement with a new thumbnail, or by entering Live View.
You control night vision features from the Camera Settings screen. To get the best results for low light conditions you adjust brightness of the infrared LED. Learn more about night vision settings here.
Another common use for Blink cameras is to alert you when activity occurs.
To detect motion, the camera is sensitive to the size of an object as it appears in the view. A small animal close to the camera could trigger similar detection as a larger animal farther away, because the appearance of their heat signature is similar. The best range of detection is within 5 to 20 feet (1.5 to 6m) of the camera.
Motion detection is also sensitive to bright flashes like those from automobile reflections, or sunlight coming through tree branches.
If you wish to be alerted to a person arriving on a walkway or path, place the camera so the direction of travel moves across the camera view, rather than towards it. When motion goes toward the camera, the image differences from moment to moment are quite small as compared with motion moving across the camera view.
To be alerted to people, rather than animals, you might place the camera so the view is above the ground high enough to not be triggered by the animal or their tail.
If you are primarily interested in arriving visitors and deliveries, it may be useful to mount the camera looking towards the doorway, so pedestrians or stray animals are not likely to enter the area, triggering a motion alert. Remember that motion across the screen (side to side) is more effective for motion detection than motion approaching the camera.
After you set motion sensitivity, it is a good idea to test it. Activate motion detection for the camera and arm the system, then walk into the camera view. Depending on your results, adjust the motion sensitivity setting, shift the camera view, or adjust infrared LED brightness. Learn more about enabling motion detection here.
In some cases, sources of sudden, or large, temperature change can trigger a motion alert. Some examples to consider are intermittent activation of a heater pilot light, heat vent on an exterior wall, or a location that is exposed to concentrated reflections during certain parts of the day.

In general, avoid placing the camera right next to a flat surface. Nearby flat surfaces reflect light and create glare, which can affect the image in many ways. Glare can also be created by momentary reflections, or a strong source of light aimed at the camera lens.
The appearance of glare can be like fog, ghosting, or a bright area of the image. In the following example, the camera is placed on the floor and the Infrared emitter is being reflected off of tile, making the image less clear in the upper center of the view. The brightness of glare can also make the background appear darker as the camera compensates for the additional 'brightness'.
Blink cameras are able to block off motion detection in certain areas that you set. Below is an image representing areas that were blocked to eliminate the tree motion, its shadow, or blowing leaves, from triggering a motion alert.
