INSTALLATION
BEA, Inc. recommends that you prepare for your installation to avoid unexpected hurdles while on the job.
1. Identify all of the entryways that will require sensors for counting coverage.
2. Review the environment of each entryway (using the following BEA mounting recommendations) to strategize sensor
placement.
a. Identify any obstructions to the detection zone (i.e. laser field).
b. Identify any objects in/near the detection zone that could affect the flow of traffic. Objects such as garbage
bins, sanitizer stations, magazine racks, or end caps can cause traffic to stop within, stall within, and straddle the
detection zone, leading to a higher rate of miscounts. If possible, such objects should be moved away from the
entrance to improve counting accuracy.
c. Understand your minimum and maximum installation height.
• MAXIMUM HEIGHT: BEA, Inc. recommends that the sensor be installed at the maximum available height (no
higher than 18 ft) for the best accuracy. If the detection zone is too wide at the maximum available height, it
can be narrowed using the LZR-SIGMA mobile app.
• MINIMUM HEIGHT: To understand your minimum installation height (no lower than 8 ft) , you must first know
the width of your desired detection area. Once the desired coverage is identified, check the chart below to
reveal your minimum installation height. You can also visit
www.meetsigma.io/sizer to use the LZR-SIGMA
sizer tool to calculate minimum installation height.
• CONNECTED SENSORS: If you have reached your maximum available mounting height, but the detection
zone is not wide enough, your application will require the installation of multiple sensors to achieve a
wider detection zone (see Application Note 78.6034 for more information on installing multiple sensors).
To determine the recommended number of sensors to use for your desired detection zone, visit
www.
meetsigma.io/sizer to use the LZR-SIGMA sizer tool.
d. Identify your power supply (location of outlets, DC supply, PoE network drops, etc).
e. Verify connectivity
–
network drop (ethernet) or cellular availability. To verify, power up the sensor and check that
the blue LED is illuminated.
