The Paranologies Paramid will detect an object and tell you whether its on the left or the right with an LCD light. This is an ultra-sonic sensor and can sense something up to 4 feet away. The Paramid has an alarm to notify you if you are not watching it. This sensor is extremely sensitive and has been created based on results from numerous paranormal investigations.
The Paramid is not recommended for small rooms as it needs 5’ of clearance to work without interference from any objects in a room. To maximize the use in a small room it will require some setup. No objects can be within 5’ of the sensor or it will give a false reading.
The Paramid is 3.5”Hx2.5”Wx5”L and requires 8 AA batteries.
