Antenna Requirements
Verint offers many antennas to meet various distance requirements. You need to consider
many factors when choosing an antenna, including the distance to cover, the RF bit rate,
the radiated power (EIRP), and the frequency band. For systems located in North America
on the 5 GHz band, you can use the Wireless System Margin Calculator located on the
Verint Video Intelligence Solutions extranet (under Tools).
You must use only antennas certified by Verint. They meet the local regulations regarding
the maximum antenna gain allowed. The certified antennas are listed in the “Compliance”
appendix on page 136.
To ensure that the device meets the maximum EIRP in the region of operation, enter the
antenna gain in the device (in the SConfigurator Wireless pane or the Wireless
Communication page of the web interface); the device will automatically take it into
account and adjust its own transmission power accordingly at startup.
For fixed point-to-point applications in the 5.725 GHz–5.850 GHz in USA and Canada,
19 dBi and 23 dBi antennas can be used without transmission power reduction. It is the
responsibility of the installer to ensure that the system is used exclusively for fixed
point-to-point operation.
RF Exposure Considerations
In order to comply with the RF exposure requirements of CFR 47 part 15 in North America,
the devices must be installed in such a way as to allow a minimum separation distance of
12 inches (30 cm) between antennas and persons nearby.
Other countries may have different regulations. Please consult with local regulations prior
to installation.
Note: Connecting an antenna with a gain higher than the value for which the device is
certified for the frequency band and region of operation is prohibited. It is your
responsibility to ensure that you respect the regulations in place.
Antenna installation must be performed by certified professionals.
