1. Product description
The fall detection radar makes algorithm judgment based on the
characteristics of personnel attitude parameters. It detects the falling
state of the target person through changes in speed, distance, attitude
and other motions, continuously records whether the target is in danger
of falling, and responds to the stationary residence alarm for long-term
abnormal stay. This product is installed on the top of the kitchen and
bathroom. The fall/still dwell function detection is not affected by
factors such as temperature, humidity, noise airflow, dust, light, and
complete stillness of the human body.

7. Radar Installation Instructions
7.1. Working range of radar module
beam coverage of the R60AFD2 radar module is shown in the figure below.
The radar coverage is a three-dimensional sector of 100 ° horizontally
and 100 ° vertically.
R60AFD2 radar coverage area
7.2. Radar installation direction and detection range
7.2.1 Wall-mounted tilting installation
*To ensure the accuracy of radar detection, please install it at an
angle of 45° !
radar is installed obliquely, and the inclination angle is 45 ° to
ensure that the main beam of the radar covers the detection area; the
recommended installation height of the radar is 2 meters ≤ H ≤ 2.4
meters , and it is recommended to install 2.2 meters by default. There
are no obvious obstructions and coverings in front of the radar.
Affected by the installation height of the radar and the range of the
radar beam, in this installation mode, the maximum radius of moving
human detection is R 3 ≈ 2.5 meters; the maximum radius of human
stationary detection is L2 ≈ 2.5 meters ; the maximum radius of fall
detection is L1 ≈ 2 meters.
Detection range
wall-mounted tilt radar when detecting human activity is about 6 meters
* 10 meters, the detection range when the human body is stationary is 4
meters * 5 meters , and the detection range of human falling is 4 meters
* 4 meters .

8. Guide to the actual installation steps of the radar
Step 1 : Confirm the main activity area of the person ( fall detection
area) , the middle of this position is the installation position of the
radar
Step 2: Confirm the actual installation height of the radar, and set the
height of the radar according to the specific height
Step 3: Determine the entrance and exit of the space, and point the long
side of the radar to the entrance and exit to ensure the trigger effect
of people entering
Step 4 : Confirm whether there is any interference source within the radar
detection range
Step 5 : Confirm whether the real use scene of the radar is a
bathroom/kitchen/bedroom and other scenarios that need to consider fall
detection and stationary parking detection, and use the fall alarm and
stationary parking alarm functions accordingly
Step 6: Follow the steps to confirm the final settings for normal use

501, West Block, Phase II, Tian 'an Innovation Technology Plaza, Futian District, Shenzhen
Space size: 3.5 ㎡ - 6 ㎡
Possible sources of interference: exhaust fans /metal shutters/ blackout
coated curtains
Installation orientation: the long side faces the door
9. Layout Requirements for Antenna and Housing
PCBA: Need to keep the height of the radar patch ≥ 1mm than other devices
Shell structure: It is necessary to maintain a distance of 3mm between the
radar antenna surface and the shell surface
Shell detection surface: non-metallic shell, need to be straight, avoid
curved surface, affect the performance of the entire scanning area.
10.Common problem
Interference factors: Radar is an electromagnetic wave detection sensor,
and active non-living will cause false alarms. The movement of metals,
liquids, can lead to false positives. Usually, electric fans, pets close

to the radar, and the shaking of metal curtains can cause false positives.
Radar needs to be planned in terms of installation angle.
Non-interfering factors: radar electromagnetic waves will penetrate human
clothing, curtains, thin wood, and glass. The installation angle and
performance of the radar need to be determined according to the application.
Semi-interference factor: Radar judges the existence of human body and is
not suitable for directly facing the air conditioner. The motor inside the
air conditioner can cause the radar to misjudge. It is required that the
radar product does not directly face the air conditioner. Or in the same
direction as the air conditioner.
