<strong>TruVision</strong> <strong>NVR</strong> <strong>20</strong> <strong>Firmware</strong> <strong>2.0</strong> <strong>Release</strong> <strong>Notes</strong> known limitations are:<br />
• In order not to avoid overloading the <strong>TruVision</strong> Encoder, TVN <strong>20</strong> limits the<br />
main stream of TVE up to 1.5Mbps (real-time @ 4CIF) and defaults its<br />
substream to 128kbps @ CIF, 6fps. Only a constant bit rate is configurable for<br />
both main stream and substream.<br />
• <strong>TruVision</strong> Encoder (multi-channel) will not be listed again at Quick Add page<br />
when at least one of its analog channels have been added. The reason is that<br />
TVR <strong>20</strong> detects devices by recognizing new IP address only. Other channels<br />
of the TVE can be added manually by specifying the IP Address and channel<br />
number on the IP Camera Config page.<br />
• The substream frame rate of a TVE channel is up to 6fps when the resolution<br />
is set as CIF. This is a performance limitation of TVE, which has been<br />
documented.<br />
• HD IP PTZ cameras listed below shall reboot when the resolution is changed<br />
by the <strong>NVR</strong>, which takes about <strong>20</strong> s. This is a known limitation of the PTZ<br />
itself.<br />

only the first six of which can be supported by the TVN<strong>20</strong>. This is a limitation.<br />
