Notes:
1. DHCP should only be enabled if using dynamic IP address notification, or if your DHCP
server can update a DNS server, which then allows you to access the VK2-540VRD by
name (host name). If DHCP is enabled and you cannot access the unit, you may have
to reset it to the factory default settings and then perform the installation again.
2. The ARP/Ping service is automatically disabled two minutes after the unit is started, or
as soon as an IP address is set.
3. Pinging the unit is still possible when this service is disabled.
3.6.1.3 Video & Image
• Video Setting
-. Codec
The codec settings are separated into MPEG4 and H.264.
H.264 is a
lso known as MPEG-4 Part 10. This is the new generation compression standard for
digital video. This function offers higher video resolution than Motion JPEG or MPEG-4 at the same
bit rate and bandwidth, or the same quality video at a lower bit rate.
-. Profile
There are 4 pre-programmed stream profiles available for quick set-up.
Choose the form of video encoding you wish to use from the drop-down list:
* H.264 MP(Main Profile):
Primarily for low-cost applications that requires additional error robustness, this profile
is used rarely in videoconferencing and mobile applications, it does add additional error
resilience tools to the Constrained Baseline Profile. The importance of this profile is
fading after the Constrained Baseline Profile has been defined.
