SECTION 4 – IP and Mesh Products

NetLink Store and Forward Solutions

The NetLink product, which has domo

technology at its core, allows Cobham

Surveillance equipment to be connected to

IP networks. In its basic form the NetLink can

be connected to the output of any standard

Cobham receiver, and translates the receiver

signal into a streaming video service.

NetLink can be set to stream at rates suitable

for either private or public networks. In private

network mode it will stream full frame rate, full

resolution video for maximum quality. When

connected to public networks where the data

rates are limited, it will produce a reduced

frame rate and resolution stream at a data

rate appropriate for the network

. NetLink uses

AES128 or AES256 encryption to ensure the

security of the transmission. These transmissions

can then be decoded in software using the

NETEPLAY application or in hardware using the

NETIPH IP Hardware (Private Network mode

only) decoder. The NetLink also has an RS232

output suitable for control of any PTZ camera

that might be connected to it. NetLink is fitted

with a USB interface for WiFi connectivity.

Net-link’s video streams can also be delivered

to BlackBerry smartphones for use in the field.

Users can choose a video stream from multiple

cameras and Net-links. BlackBerrys can be CESG-

accredited to Restricted.

NetLink is supplied in a sealed rugged aluminium

box suitable for long term security deployments.

The NetLink product can be upgraded with some

powerful options:

• NetLink DVRI – Upgrading the NetLink

with an internal or remote DVR option, which

creates a sophisticated ‘store and forward’

product, allows the viewing of video across

real world low bitrate public networks,

such as 3G or the internet. The DVR option

records the incoming high quality video to

a local hard disk, whilst streaming out a live

low bitrate thumbnail service to the user at

a capacity which matches that available on

the public network. If the user is interested

in something seen on the thumbnail stream,

then the high quality video can be retrieved

in non-real time by download from the hard

disk. To assist the user to retrieve the video

of interest, NetLink offers a sophisticated

range of time logging and trigger functions,

and also fast forward and rewind viewing

options. It can be connected to external

sensors to trigger recording or build a time-

stamped graph of events. By clicking on a

speciﬁc event, the software will automatically

download the corresponding video fragment.

NetLink is a multi-cast product when used

on a private LAN or a uni-cast product when

used over the internet.

• NetLink AV – Upgrading the NetLink with

the video input option enables the NetLink to

connect direct to a camera,

in addition to being able to connect to the

output of a Cobham microwave receiver.

This function enables IP video and audio

transmission across public and private

networks.
