WARNING
• Do perform all network functions of data communication within an enclosed network.
A.13.2.1 System capacity and resistance to wireless interference
Meets the following requirements:
■ All the monitors do not encounter communication loss.
■ The total delay of data transmission from the monitor to the CMS: ≤ 2 seconds.
■ The delay for monitor-related settings configured at the CMS to be effective: ≤ 2 seconds.
■ The total delay of data transmission from one monitor to the other: ≤ 2 seconds.
■ The delay for the monitor to reset alarms of another to be effective: ≤ 2 seconds.
■ The total delay of data transmission from the TM80 to the monitor: ≤ 2 seconds.
Testing conditions are as follows:
■ Number of the monitors supported by a single AP: ≤ 12 (for N22/N19) or ≤ 16 (for N17/N15/N12/N12C).
■ Each monitor can communicate with the CMS.
■ Two monitors are used to view other monitors.
■ Five monitors are connected to TM80s.
■ Only one monitor can transmit history data.
■ The weakest strength of the AP signal where the monitor is located is not less than -65 dBm.
■ The distance between the interfering devices and the monitor is greater than 20 cm. A Wi-Fi interference
(no greater than -85 dBm) in the same channel and a Wi-Fi interference (no greater than -50 dBm) in an
adjacent-channel are presented synchronously. The interfering devices include, but are not limited to, 2.4 G
wireless devices, cellular mobile networks, microwave ovens, interphones, cordless phones, and ESU
equipment. The interfering devices do not include Wi-Fi devices.
A.13.2.2 Wi-Fi network stability
The ratio of the communication data loss on the CMS from any monitor does not exceed 0.1% over a 24-hour
period (for N17/N15/N12/N12C, 12 of the 16 monitors connected to the network roam for 30 times).
Testing conditions are as follows:
■ Number of the monitors supported by a single AP: ≤ 12 (for N22/N19) or ≤ 16 (for N17/N15/N12/N12C).
■ Each monitor can communicate with the CMS.
■ Two monitors are used to view other monitors.
■ Five monitors are connected to TM80s.
■ Only one monitor can transmit history data.
■ The weakest strength of the AP signal where the monitor is located cannot be less than -65 dBm.
A.13.2.3 Distinct vision distance
The distinct vision distance between the monitor and the AP is no less than to 50 meters.
