Improving security across an expanding site

How Treviglas College in Cornwall, UK, used Axis IP-Surveillance and Power over Ethernet to ensure cost-effective, high quality security

Specifying new surveillance system requirements

It was clear as far back as 2003 that the traditional analog-based CCTV system the college used had not been meeting the needs of the college for some time.

Gary Durbin, Assistant Headteacher, explained: "The old system had often left staff compromised because we could not be sure who had been involved in a recorded incident."

Any new system, it was ruled, had to generate and efficiently store images of sufficient quality to positively identify individuals for use as evidence when needing to take action against anyone perpetrating an action against the site or against another person.

The IP Way

The college’s IT team favoured an IP-based surveillance solution having already trialed a network camera several years previously and recognised the benefits of using the up-to-date and well-maintained network and the CAT 5e cabling infrastructure already in place across all the buildings of the college.

Deploying Power over Ethernet-enabled network cameras eliminated costs that would otherwise be associated with running electrical wiring to new cameras.

The new IP-Surveillance System - in depth

Two AXIS 241Q Video Servers with four analog cameras on each are deployed to take images from existing analog cameras and relay them into the network. A total of 18 AXIS 211 Power-over-Ethernet Network Cameras, and one AXIS 2130 PTZ Network Camera were deployed across the entire campus. A total of 27 cameras feed into the Milestone XProtect Enterprise Version 5.0 system for handling, storage and management of camera output.

The AXIS 2130 Pan Tilt Zoom Network Camera is situated on an eight metre tilt over column in a glass dome housing and provides coverage over the adjoining primary school’s playground as well as the college buildings and playing fields. Since the establishment of this PTZ, problems of vandalism across both sites have been very noticeably reduced. A Dell Server with 700 Gigabit SATA Drives has been deployed to hold all images. Image recording is triggered on motion and records at maximum of 25 frames per second using medium compression ratios and 640x480 resolutions for viewing. Images are kept for nine days and are archived for a total of 30 days, these are archived on both hard drives and Sony Ait 3 drive with 100 GB tape storage.

The caretakers of the college are specifically tasked with checking the units for any evidence of damage and reporting any maintenance requirements to the IT department to avoid deterioration in quality of output over time. They work until 10PM and then a private security company begins work to patrol the grounds through the night.
