Pole and device installation distance note：
Snapshot distance：22 meters；
Camera installation height：6 meters；
The limit of side install is the 2nd lane, not 3rd lane since its side installation is too big, cannot be
detected.
Advantage and disadvantage
Advantage：
①Image effect, tails of large, small vehicles or motor are 90% clear；
②Compare to vehicle head plan, this plan largely improves recognition of motor plan, especially
at night time from 40% to 70%.
Disadvantage：Compare to vehicle head plan, this plan cannot get face details of driver, so lose
partial vehicle info.

Chapter 6 FAQ
FAQ
Solution
Device is abnormal, cannot
boot up or be operated
Device is abnormal and cannot operate or cannot boot up, press Reset
key for 5 seconds to restore default settings.
WEB control unit did not pop
up webrec.cab
Please lower Internet Explorer security level to the lowest, set
“ActiveX plug in and control unit”to “enabled”.
Focus not clear at night
At day time, manually adjust iris to max, and manually focus or use
ABF (do not touchABF during other time)
Plate effect is weak at night
1. Confirm focus clarity；
2. At night, use linear WDR；（ adjust WDR to below 50 at night,
default is OK）
3. Ensure use of IR7 on site, light cup angle is 15 degrees。
Snapshot rate is low at night
1. Recommend vehicle tail snapshot plan；
2. Ensure snapshot effect is ok；
3. Use version after Jan.12th .
