Choosing A Camera Sensor Mount Location
1. Where to Place Your Camera Sensors
Choosing the accurate location and the proper number of camera sensors in your house and rooms is important for optimal fall detection. It’s important to properly position each camera to avoid any blind spots and ensure good coverage.
It is advised to install two camera sensors opposite each other per room to cover as much ground as possible. Each camera's Field Of View (FOV) must overlap with the blind spot of the other camera sensor to eliminate the blind spots and hence the chances of missing a fall.
Below are a few things to consider when choosing your camera sensor placement.
You must not place your camera sensor above a door like the entrance to a room, or a door leading to the bathroom where you expect frequent movement directly under the camera sensor.
We don’t recommend placing your camera sensor above a window, as the power cord will be right in front of the window.
1.3 Outlet Availability
The location of the power outlets in the room will be an important determinant factor when choosing your camera sensor's locations. You should consider the length of the power chord (9 feet or 3 meters) and position your camera sensor as close as possible to a power outlet.
2. Ceiling and wall mount
If you decide to mount your camera sensor on the ceiling, we recommend mounting it in the corner of the room. If the ceiling is higher than 9 feet (3 meters) or if it’s made of concrete, then you should mount your camera sensor on a wall.
3. Dealing With Blind Spots
3.1 Bed away from the wall example
If furniture like a sofa or a bed is away from the wall, a blind spot will appear on the opposite side of this furniture. In this case, you will need to position your camera sensor above the bed for example, as seen in the image below in camera sensor 1.
You will also need to position a second camera sensor that can see the blind spot on the opposite side of the bed. The recommended spot is on the opposite wall right in line with the bed blind spot as seen in camera sensor 3 in the image below.
3.2 Bed against the wall and hallway example
Let's say that the bed is against a wall. Then there will be no blind spot behind the bed. However, camera sensor 2 below cannot see around the corner in the hallway. To avoid the blind spot around the corner in the entryway, a second camera sensor, camera sensor 4, should be placed in the opposite corner of camera sensor 2 as shown below.
Note that camera sensor 4 has a furniture blind spot behind the dresser as shown below. However, as camera sensor 2 is placed in direct view of the dresser blind spot, it eliminates that blind spot.
3.3 Bed in the middle of a wall
If the bed is in the middle of the wall, you can position your camera sensor over the bed. The blind spot under the camera sensor will be right above the bed, and your camera sensor’s FoV will be able to see each side of the bed. Position another camera sensor on the opposite wall facing the foot of the bed.
If your room has an entry hallway with a door to the bathroom, position your camera sensor on the opposite wall of the hallway facing the hallway to cover the room and the bathroom entries.
