BAI Reader Location

Recommended Distance From the Gate Operator

Overhead view of Installation

As shown in this illustration, the reader should be located approximately 25 feet before the

gate. This allows about one car length (plus a small gap) for vehicles to pass the reader

before stopping at the gate. The barcode decal is placed on one of the rear side windows of

the vehicle in an unobtrusive spot. On most vehicles, this will be about 10' to15' back from the

front bumper. For the BAI reader to work, the vehicle “pulls” the decal past the reader on its

way to the gate.

This mounting location is recommended as it produces the best performance and reliability

within the reader specifications. BAI readers will reliably read decals on vehicles moving up to

25 mph at distances up to 6' away. It does not matter which side of the road the reader is

mounted on, as long as the vehicle decals are also on the same side. Based on reports from

over 1,200 different sites, the 25' recommended distance is simply the best position for

mounting the reader. If necessary, the reader can be mounted closer to the gate or farther

away from the gate. However, moving the reader may affect the performance and reliability

depending on conditions at the site.

If the reader is located too close to the gate, there may be problems reading decals. For

example, suppose a reader is mounted 10' in front of the gate. Decals are placed in the usual

position on the rear side window of the vehicle, which is 10' to 15' back from the front bumper.

As the vehicle passes the reader, it will have to stop at the gate before the decal reaches

the read zone. With the reader only 10' from the gate, all vehicle decals will have to be

placed closer (in this case, less than 10') to the front bumper. This means placing decals on

the front side windows, which may interfere with driver vision, is far more noticeable, and still

does not guarantee reliable reading on long vehicles.

If the reader is located too far from the gate, there will be problems. For example,

suppose a reader is mounted 40' in front of the gate. Decals are placed in the usual position

on the rear side window of the vehicle, which is 10' to 15' back from the front bumper. As the

vehicle passes the reader, it will read normally. The problems with this mounting location

primarily concern (1) vehicle speed and (2) having multiple vehicles between the reader and

gate.
