Ceiling Mounted Occupancy Sensor Buying Guide
Ceiling mounted occupancy sensors can be a little more pricey compared to wall switch occupancy sensors. There is good reason behind this and when installed for the right application they are very cost effective. A typical wall switch occupancy sensor only detects 150 to 180 degress of motion from the source. To justify, it is mounted on a wall and can only see to the left, right and straight ahead to detect motion. A ceiling mounted occupancy sensors detects motion in 360 degrees from a birds eye view. This is beneficial for many reasons. First, it is placed above any still objects such as open doors or partitions; and second, it is capable of detecting motion at several entrances in a room where wall switch occupancy sensors can only see one or two. When deciding which occupancy sensor to buy you must consider your specific application of the sensor, and not shy away from one just because it is more expensive. To put this in perspective, one ceiling mounted occupancy sensor can cover a room or space that may take up to 3 occupancy sensors to effectively cover.
