Securing a School in Northern Ireland: CCTV and Access Control

A worked example rather than a named customer: how Advanced Overwatch would replace an ageing school CCTV system and add managed access control at the main entrance, from one local Northern Ireland team.

Worked Example, Education

Sector: Education | Location: Northern Ireland | System Type: CCTV + Access Control

Schools across Northern Ireland face a unique set of security pressures. They must protect pupils, staff and visitors during the school day while also deterring vandalism and break-ins outside school hours, all without creating an environment that feels like a surveillance facility.

Take a school with an ageing CCTV setup that has reached the end of its serviceable life. The cameras are analogue, low-resolution and offer no remote viewing, and there is a gap in access control at the main entrance: visitors can walk in unchallenged, creating a safeguarding risk the governors want to close. The rest of this page is a worked example of how we would answer that, not an account of a particular school.

What this school would need

A school in that position needs a solution that would:

Replace failing analogue cameras with high-definition IP cameras covering all entrances, corridors and the car park
Allow the headteacher and designated safeguarding lead to view live and recorded footage remotely
Control access at the main entrance so all visitors were signed in and verified before entering the building
Meet the duty-of-care requirements expected of a modern educational facility
Be unobtrusive and appropriate for a school environment

A proposed approach.
Two systems to consider.

Advanced Overwatch would start with a full site survey, mapping existing cable runs, identifying coverage blind spots and assessing the most practical entry points for an access control system.

CCTV system

CCTV system: we would install a set of Hikvision 4MP AcuSense turret cameras across the site, covering the main entrance and car park (with overlapping coverage), the front and rear pedestrian gates, the main reception and the corridor leading to classrooms, and the external building perimeters facing the rear playground. AcuSense technology filters out false motion alerts triggered by animals or wind, so the system only flags human or vehicle movement, particularly valuable for out-of-hours monitoring. The cameras feed to a network video recorder (NVR) with 30 days of local storage, and remote viewing is configured via Hik-Connect, giving the headteacher secure mobile access without a separate subscription service.

Managed entrance

Access control: we would install a Paxton Net2 entry system on the main entrance. Visitors present at an audio/video intercom panel before being remotely admitted by reception staff, and a detailed entry/exit log is maintained automatically, giving the school a complete audit trail for safeguarding purposes. Staff access credentials are managed centrally, so permissions can be updated instantly when staffing changes occur, a significant improvement on a building that relies on physical keys.

Expected changes in
this worked example

With the new systems in place, a school of this kind gains:

Full HD, evidence-quality footage in place of unusable low-resolution recordings
Remote monitoring, letting the headteacher verify site security outside school hours without attending in person
A complete visitor log managed automatically by the Paxton system, supporting the school’s safeguarding obligations
Less time spent by reception staff managing the entrance manually

Planning around the school day

We understand that schools have different needs from commercial premises. Our engineers work around term timetables, communicate clearly with non-technical staff, and leave sites clean and tidy.

All works are carried out in accordance with our SSAIB Certified Company status (NIRE127) and our ISO 9001, ISO 14001, ISO 27001 and ISO 45001 certified management systems.

Advanced Overwatch is one of very few security companies in Northern Ireland to hold SSAIB Certification across all three major disciplines: intruder alarms, CCTV and access control. We are also ISO 9001, ISO 14001, ISO 27001 and ISO 45001 certified, meaning every installation is backed by independently audited quality, environmental and information-security management systems.

School CCTV and access control questions

Do you install CCTV and access control in schools across Northern Ireland?

Yes. Advanced Overwatch designs, installs and maintains CCTV and access control for schools and other education settings right across Northern Ireland. Advanced Overwatch is SSAIB certificated (NIRE127) specifically for Intruder Alarm Systems, Visual Surveillance Systems (VSS) and Access Control Systems. We work as one local team.

Can you work around the school day and term timetable?

Yes. We plan school installations around teaching, break times and term dates so the work causes as little disruption as possible, and we leave every site clean and tidy. Our engineers are used to communicating clearly with non-technical staff and governors.

Does the access control system support our safeguarding obligations?

A managed entry system, such as the Paxton Net2 setup described above, holds visitors at the entrance until reception admits them and keeps an automatic entry/exit log, giving the school a complete audit trail. Staff credentials are managed centrally so permissions can be updated instantly when staffing changes.

Are your installations properly certified?

Yes. Advanced Overwatch is SSAIB certificated (NIRE127) specifically for Intruder Alarm Systems, Visual Surveillance Systems (VSS) and Access Control Systems. Every installation follows our ISO 9001, ISO 14001, ISO 27001 and ISO 45001 certified management systems, independently audited quality, environmental and information-security standards.
