As the resolution of network cameras
increases, processing and displaying
video streams is placing heavier
demands on hardware. Handling
multiple channels of streaming video
is especially challenging.
Scalable Video Coding (SVC) is a
video standard based on H.264 that
allows video data to be divided into
multiple layers with different
resolutions, picture sizes, and frame
rates. SVC provides the flexibility to
optimize such video to account for
limited network bandwidth, available
processing capacity, and varied
display devices.
Conventional network cameras require a power cable for power supply and an Ethernet cable for data transmission. PoE
(Power-over-Ethernet), developed by the IEEE802.3af task force, enables power to be supplied over a single Ethernet cable, and
thus eliminates the need for a separate power cable. By connecting a PoE-supported camera to a PoE switch, you need not deploy
additional power cables. PoE Plus is the advanced version of traditional PoE. Following the new IEEE 803.3at standard, PoE Plus
provides up to 30 watts of power, enough for outdoor speed dome cameras and allowing for more flexible, hassle-free installation.
The IPv6 standard consists of 128 bits which are divided into eight parts, each group containing four 16-bit digits separated by a
colon. IPv6 IP addresses are presented in a different format from IPv4, for example 3ffe:0305:0000:0000:0000:0000:0000:0001.

Tamper detection can detect and respond when a camera is redirected, defocused, blocked, or spray-printed. It allows cameras to
be installed in tampering-prone places such as transportation stations or prisons.
Tamper Detection
Intelligent motion detection can distinguish object motion
from environmental movement and trigger alarm solely on
object motion. This feature, used mainly in outdoor
applications, can eliminate false alarm due to wind, rain, or
other environmental noise.
Intelligent Motion Detection
Loitering detection detects an object or person which has
remained in a predefined area over a given time period. This
function is effective at preventing crimes since suspicious
objects or activities are often detected before damage has
occurred.
