Remote Monitoring for Video Surveillance Systems<br />

triggered by a detector-only security system,<br />

which brings me neatly on to the subject of<br />

‘tough love’.<br />

Ensuring Best Practice<br />

Remotely-monitored security systems eliminate<br />

the risk of the police having to respond to false<br />

alarms. Instead, they place the burden on the<br />

RVRC to filter them out and the cost of doing so<br />

on to the end user. If false alarm incidents are<br />

to be minimised, it’s therefore essential that<br />

the installer and the RVRC work closely<br />

together to ensure Best Practice when the<br />

system’s being installed and commissioned.<br />

Some installers may regard the RVRC as<br />

being ‘difficult’ due to insisting on the following<br />

procedures, but by complying they will ensure<br />

that the cost of monitoring a detector-based<br />

intrusion system will be minimised:<br />

• Commissioning: This process must follow a<br />

logical progression in order to verify that<br />

detection devices and cameras are tested<br />

• Daytime Walk Test: This involves an engineer<br />

on site creating an alarm by walking around the<br />

location such that every sensor installed<br />

delivers an alarm image to the RVRC. In doing<br />

so, the engineer should ensure that each<br />

detector is correctly assigned to an appropriate<br />

camera and, where a camera with telemetry is<br />

installed, the correct pre-set is configured.<br />

Testing of all arming and disarming devices<br />

should be carried out at the same time<br />

• Night-Time Image Testing: This is intended to<br />

assess the quality of supplementary lighting<br />

and image resolution<br />

• Lighting Rating Scale: The RVRC should<br />

complete a lighting report as part of the<br />

commissioning process for all new connections,<br />

with snapshot images taken from all cameras<br />

during the day and then again at night. The<br />

report will identify if there’s adequate visibility<br />

in all lighting conditions or if poor visibility<br />

necessitates the requirement for additional<br />

lighting to be installed<br />

• Seven-Day Environmental Soak Testing:<br />

During this period, the system remains under<br />

detailed review to allow for evaluation of the<br />

effects of environmental influences<br />

Harsh environments<br />

A professionally-designed, installed and<br />

commissioned remotely-monitored video<br />

“Remotely-monitored security systems eliminate the risk of<br />

the police having to respond to false alarms. Instead, they<br />

place the burden on the RVRC to filter them out and the<br />

cost of doing so on to the end user”<br />

system can be effective and reliable even in the<br />

most harsh of environments. Battery<br />

technology has now advanced to the stage<br />

where a system can be rapidly deployed to a<br />

site where an electricity power supply may not<br />

be readily available and, in the absence of<br />

access to the network for transmission over<br />

broadband, it’s now possible to use 3G, 4G or<br />

even satellite technology to ensure<br />

communication between a site and an RVRC.<br />

Depending on the location of the site, pointto-point<br />

wireless transmission is also an option<br />

as it’s able to send high quality video over long<br />

distances with extremely low latency. It’s not<br />

unknown for a combination of satellite, pointto-point<br />

wireless and broadband to be used to<br />

meet the challenge of transmitting data and<br />

audio as well as video over large distances.<br />

The resolution of images captured by the<br />

latest generation of HD cameras means that,<br />

provided they’re correctly installed and<br />

configured, it’s virtually guaranteed RVRCs will<br />

receive video of sufficient clarity to enable<br />

operators to rapidly decide on an appropriate<br />

course of action when lighting and weather<br />

conditions are good.<br />

On that note, bear in mind that thermal<br />

imaging cameras now offer an affordable<br />

solution for those sites which may be subject to<br />

low-light or variable weather conditions.<br />

How to select RVRCs<br />

There’s no shortage of monitoring centres who<br />

will want your business, but their ability to<br />

meet your expectations as an end user will vary.<br />

Here are some tips to maximise the possibility<br />

of you choosing an RVRC which is able to<br />

deliver the service levels you require.<br />

Visit the National Security Inspectorate’s<br />

website at www.nsi.org.uk where you’ll find a<br />

directory of accredited RVRCs that operate to<br />

British Standards BS 5979 Category II and BS<br />

8418. Also, seek confirmation that the selected<br />

RVRC is independently inspected to the quality<br />

standard ISO 9001:2000.<br />

Further, check that the RVRC is approved to<br />

operate the monitoring centre platforms – such<br />

as Sureview Immix and Sentinel Plus – from<br />

leading software developers, and that it’s able<br />

to support IP, 3G and 4G transmission protocols<br />

(as well as, if appropriate to you, legacy ISDN<br />

and PSTN systems).<br />

Last, but not least, ascertain if the RVRC has<br />

field-based and in-house technical support<br />

personnel on board who will liaise with your<br />

installation company every step of the way,<br />

from system design right through to<br />

commissioning, in order to ensure optimum<br />

performance of your security systems.<br />
