For example, consider the following setup:
You should update the devices in the following order:
1. S4200 1—You then lose contact with S4200 1.
2. S4200 2—You then lose contact with S4200 2.
3. S4300 1—You can then reach all devices.
4. S4300 2—You then lose contact will all devices except master S4300 3.
5. S4300 3—You can then reach all devices.
For the complete firmware update procedure, refer to the documentation of the Verint
software you are using.
Video Bit Rate and Data Throughput
You can theoretically connect up to 24 S4200 devices to a master access point in a wireless
cell. In practice however, video quality, frame rate, and system layout can limit the number
of devices that a single master access point can support.
Available video data throughput can be evaluated using the Wireless System Margin
Calculator that you can find on the Verint extranet. Available video data throughput
depends on the transmission (tx) bit rate used by each slave on the wireless network.
Video quality and frame rate influence the required data throughput. Therefore, you need
to carefully plan the number of cameras that will work on a link.
The following figures were measured in typical setup situations. They may vary depending
on your configuration. The total data throughput in a unidirectional UDP link setup varies
depending on the frequency channel width: 20 MHz in all available bands, or 5 MHz and
10 MHz in the 4.9 GHz frequency band.
The throughput for a 20 MHz channel is:
