ISO Integration improves hospital security awareness
The project is allowing IP cameras from Avigilon to operate alongside existing analogue cameras at the hospital
ISO Integration, the installation arm of Rainbow CCTV, has recently completed a camera surveillance project for the Chapman Medical Centre in Orange County, California.

The project is allowing newly-installed IP cameras from Avigilon to operate alongside existing analogue cameras at the hospital that are still fit for purpose. ISO Integration has been able to protect its client's investment in the legacy units and provide an ongoing migration path using the Control Centre video management system (VMS) from Avigilon whose open-architecture platform accepts input from multiple manufacturers and ensures ultimate scalability along various paths.

The cameras being used are dome units with varifocal lenses. Engineers from ISO Integration were able to plug these into an Avigilon encoder and then make a simple Ethernet connection to the hospital's network switches so that the network and video matching software could view and record both types of camera feed as well as applying motion detection and video analytics.

David Darling is IP Video Sales Manager at ISO Integration. He said: "With healthcare facilities wanting to maximise patient, staff and visitor safety but needing to focus their principal investment on clinical excellence, our value proposition was that by using encoders we were able to produce an IP stream from the analogue cameras while also integrating pure IP cameras into a unified control and monitoring platform. This is also a ‘green' solution since viable units have remained in situ."

Intelligent scene analysis is optimising the camera system's use of RAID, this being an important consideration in hospitals where increasing digitisation of medical records makes demands on storage. Intelligent, selective video transmission optimises use of bandwidth, preserves storage capacity and reins in cost.

ISO Integration has introduced 1, 2, 5 and 8-megapixel cameras in lobby and reception points at the hospital



David Darling continued: "A feature of high-end software such as Avigilon's Control Center is the ability to search footage for a significant event based on changes in even a portion of the frame over a particular timeline. Such a review can be performed from any computer on the hospital campus or indeed remotely, a facility that is being used to significant effect by senior management at the Chapman Medical Centre. ISO Integration's engineers worked seamlessly with the hospital's IT department, ensuring that IP addresses were immediately secure, and accommodating the client's style of network usage."

ISO Integration has introduced one, two, five and eight-megapixel cameras, making effective use of wide viewing angles in lobby and reception points at the hospital. The surveillance cameras cover areas including medical emergency and surgery centres, ambulance arrival bays, cafeterias and external walkways which are benefiting from IR illumination. There is extensive surveillance of car parks to promote safety and discourage loitering or other inappropriate behaviour.

Wiring at the facility is a combination of Cat5e and fibre optics, while switching units are predominantly Cisco with the existing 2.5 TB Dell server set to increase fourfold. The project features use of COTS (‘commercial off the shelf') hardware and software, this being characteristic of the transparent working methods adopted by ISO Integration.

Use of sophisticated video surveillance at the medical centre has been a catalyst for general cultural change, with employees at all levels of seniority giving more thought to security, lighting, use of gates and barriers and promotion of patient and staff wellbeing through technology. Possible future developments include enhanced perimeter intrusion, access control and automated time and attendance.

Jason Shane is the Director of Security at Chapman Medical Centre. Mr Shane has taken a close interest in the implementation of the surveillance equipment and has assessed its functionality carefully.

He said: "Judicious use of high-quality cameras has enhanced our awareness of the facility in general. The cameras have helped us become aware of questionable activity in our rear car parks, exterior lights that were failing, inappropriate use of emergency exits by staff, and exterior doors failing to be locked as expected."

Mr Shane continued: "It is well known that hospitals are facing increased security challenges. Our senior management are very pleased with their investment in this new video surveillance system to help us meet these challenges. The system has improved staff security awareness, helped us satisfy new legislation to improve patient/visitor safety and is protecting hospital assets from theft and vandalism."

Founded in 1969, Chapman Medical Centre includes a 114-bed acute care facility that provides high-technology tertiary services for central Orange County. The centre's newest signature services are its neurosurgical and spine programmes. The hospital is also respected for work in areas including gastric bypass surgery, orthopaedics and bloodless medicine.

ISO Integration has particular expertise in the healthcare and education sectors but is also targeting niche markets such as shopping centres and car dealerships. The company is equally at home working with civic and commercial clients. In addition to video surveillance, services offered include perimeter intrusion, access control and video analytics.
