Key Entry Format

The wireless passkey can have two formats: String (default) or Hexadecimal.

Tx Power Scale

The transmission power scale indicates the level of emitting power of the device radio. The

available values are:

 Maximum—The maximum allowed.

 50%—The power is reduced by 3 dB.

 25%—The power is reduced by 6 dB.

 12.5%—The power is reduced by 9 dB.

 Minimum—The power is set at 3 dBm.

By default, the transmission power scale of a device subject to the TPC regulations is set to

50%.

Sensitivity Threshold

The sensitivity threshold is the minimum signal level perceived by the radio of the device.

Reducing the sensitivity of the radio enables unwanted “noise” to be filtered out. A safe

value is 10 dB below the current received signal level (displayed in the Advanced >

Communication Status and Statistics > Wireless Status menu).

The default value, Normal, represents the most sensitive context. You must be careful not

to reduce the sensitivity to a level where the device would not “hear” its legitimate

correspondent.

Minimum Margin

The minimum margin is used when the transmission bit rate is set to Auto (see page 38). It

represents the difference in dB between the actual signal received by the device and the

minimum signal required by a given bit rate to correctly receive data on the RF link. The

default minimum margin is 15 dB.

Indoor/Outdoor RF Regulation

Depending on the country of operation and the chosen frequency band, the device is

allowed to operate indoors only, outdoors only, or either indoors or outdoors. The frequency

channels available in the indoor-only regulation are different from those assigned to

indoors/outdoors; the same goes for the outdoor-only channels.

Note: Under the RF regulation, a device programmed to be used only indoors must not be

installed outdoors, and vice versa.

To know which frequency channels are available in your country of operation in each of the

three operation modes, refer to the Wireless Frequency Plan document located on the

Verint Video Solutions extranet (Technical Support, then Downloads, then Tools).

The default factory value for most countries is indoor/outdoor.
