4.4.1 Application Limitations
SW Requirements:
The application can be installed on all Smartphones that support Android 4.2
and higher or iOS 8.x and higher.
HW Requirements:
The Smartphone/tablet must be equipped with a functional microphone, speaker
and Wi-Fi or data connection.
LAN/Internet Connection Requirements:
The application requires a Wi-Fi Access Point or Wi-Fi router that supports the
802.11g standard at least. The ideal solution includes 802.11n or 802.11ac
supporting access points because of the higher bit rate of the LAN.
The LAN in which the application is running should not be overloaded with other
transmissions to avoid video transmission errors.
Tip
Should there be problems with the videos, you can lower 2N Helios IP
the video transmission quality. If this is still insufficient, lower the
network load or set QoS for your access point to earmark some of the
transmission bandwidth for the application.
Make sure that the access point supports Unicast, Multicast, TCP and UDP.
Warning
If you select Unicast, video will only be displayed on 3–5 devices due to
a heavy network load. Therefore, Multicast is recommended for
installations with a rather high count of applications.
Tip
