DEVELOPED by
Naskam Security Services, the purpose-built control room provides live surveillance
services to a diverse range of remote sites across Australia.

“Over 5 years
ago, Naskam set about looking for a quality product that would allow us to
provide live video monitoring services to clients across the country at an
affordable cost, whilst providing the highest quality of recording equipment,”
said Chad Wright, Naskam’s general manager.

“After testing
many different vendors, we chose IndigoVision’s solution as it provided us with
a number of unique features and the ability to deliver excellent video quality,
with minimum bandwidth.”

“IndigoVision’s
compression technology allows Naskam to monitor high-quality video from remote
sites using Next G/3G wireless links where traditional hardwired ADSL or fibre
connections are not available.

“This enables
Naskam to maximise the number of cameras that can be monitored over the
available bandwidth and minimise their network costs.”

Naskam currently
monitors numerous remote sites including shopping centres, city centres and
utility infrastructures and encourages each site to use dual streaming and
local recording on IndigoVision’s Network Video Recorders (NVRs).

In this
configuration each camera produces two video streams, a higher resolution
stream for local NVR archiving and a lower resolution stream, typically 2SIF @
12 to 25fps, for transmission to the remote monitoring centre. Recorded video
can also be accessed at the monitoring centre if required.

The low bandwidth
requirement also ensures low latency, which allows Naskam’s operators to
smoothly control PTZ cameras at each remote site. Live video monitoring and
camera control is achieved using workstations running Control Center,
IndigoVision’s Security Management Software.

“The first
installation of a live monitored site was a small remote shopping centre where
IndigoVision’s IP Video transmitters were installed along with analogue
surveillance cameras, PA speakers, strobes and PIR’s for video alarm
activation,” explains Wright.

“Within two weeks
of deployment, several youths had already been apprehended for various crimes.
Local security patrols had failed for years to catch these criminals, whereas
the video monitoring service worked immediately.

“Teaming this
service up with live and pre-recorded audio announcements has meant that the
system helps prevent crime by alerting people that they are entering a
monitored area.”

The ability to
transmit and receive synchronised full-duplex, high-fidelity audio alongside
the video over the network was another feature that attracted Naskam to
IndigoVision’s solution. Built-in PA facilities allow operators to broadcast
audio announcements through speakers connected to the IP Video transmitters.
Similarly microphones can be installed locally to capture audio recordings or
enable two-way conversations.

IndigoVision’s
advanced analytics and alarm management capabilities are used extensively by
Naskam to help automate the monitoring process and improve incident response.
Analytics functions such as virtual tripwire, congestion, motion detection and
counterflow are used to trigger alarms. These alarms automatically alert
operators to the potential incident and can trigger actions such as panning a
remote camera to a pre-configured position.

They also use the
Alarm Preview feature, which automatically displays the previous 10 seconds of
recorded video prior to the alarm activation, helping operators to quickly
assess the situation. Through the use of I/O built into IndigoVision
transmitter modules, discrete signals from other security systems can also be
monitored and used to trigger alarms.
