The TVN 20 can also support a limited amount of 3 and 5 Megapixel cameras.
The chart below identifies these capabilities. It is important to note that the
maximum data rate per channel that the device can support is 8 Mbps.
Maximum # of 3 Megapixel cameras per unit:
 8-Channel Unit = 2
 16-Channel Unit = 4
Maximum # of 5 Megapixel cameras per unit:
 8-Channel = 2
 16-Channel = 4
Budgeting Unit Capacity
The maximum data rate supported by the unit regardless if it is an 8 or 16
channel unit is 64Mbps. When populating the TVN 20 it is important to consider:
 Data Rate in Mbps of Cameras being Recorded simultaneously
 Data Rate in Mbps of Cameras being Streamed Live (Preview) simultaneously
 Data Rate in Mbps of Cameras in Playback simultaneously
The sum total of these simultaneous actions must not exceed 64 Mbps. Possible
system behaviors in these cases are the following:
 Video may continue to record (as Recording is a priority event with the TVN 20)
 Live viewing will no longer support the number of simultaneous live (preview)
camera displays
 Playback may take longer to load than normal
 Live and playback images may experience increased packet loss resulting in a
degraded picture
