VIDEO STREAMING
Many Axis network video products oer users the
option of more than one video compression format.
The video compression standards include Motion JPEG,
MPEG-4 Part 2 and H.264 (also known as MPEG-4 Part
10/AVC). H.264 is the latest compression standard that
oers the most ecient format for compressing video,
enabling great savings in bandwidth and storage with-
out compromising image quality.
The Axis Media Control (AMC) includes both an MPEG-4
and an H.264 decoder, which makes viewing video
streams and integration into applications easy.
Furthermore, Axis’ multicasting support enables an un-
limited number of viewers without sacricing network
system performance.
POWER OVER ETHERNET (PoE)
With a network video solution, you have the option of
using the same Ethernet cable for video, audio and pow-
er. This makes it easier to install products since an elec-
trician is not required and the network video product is
able to operate even when there is a power failure if the
PoE source is connected to a UPS.
PoE technology is regulated in standards called IEEE
802.3af/802.3at and is designed in a way that does not
degrade the network performance or decrease the net-
work reach.
The standard IEEE 802.3at provides up to 25.5 W of
power, especially useful for powering units that requires
more power, such as PTZ and PTZ Dome cameras.
The power delivered over the network is automatically
activated when a compatible product is identied, and
blocked to legacy devices that are not compatible. This
feature allows users to freely and safely mix legacy and
PoE-compatible devices on their network.
