Intercom & Door Entry Solutions for Educational Properties in Surrey


Audio and video entry systems for schools, colleges and nurseries — designed to support safeguarding, visitor management and controlled access.


Schools and education sites need calm, controlled entry — without creating bottlenecks at the start and end of the day.


OC Services designs, installs and maintains intercom and door entry systems for education settings across Surrey, including primary schools, secondary schools, academies, colleges, nurseries and wraparound care.


Whether you need a simple audio intercom at a staff entrance or a video door entry systemat reception, we’ll recommend a solution that supports your safeguarding approach and day-to-day workflow.

Our Door Entry Solutions

Survey, Design & Installation

We start with a site survey to confirm:

  • how visitors arrive (gated entrance, shared entrance, rear door)
  • who needs to answer calls (trade counter, multiple tenants, mobile users)
  • what you need to control (main door, side door, gates, barriers)

Then we design a door entry system that’s secure, reliable and easy to use.

Video door entry (controlled access points)

A popular option for reception/main doors where staff need to see who is requesting access. Systems can be specified to support:

  • clear video at the entrance
  • two-way audio
  • low-light/night performance (useful in winter)
  • multiple answering points (e.g., reception + head’s office)
  • secure door release (electric strike/maglock) where appropriate

Audio intercom (simple, robust entry control)

Ideal for staff entrances, side doors and delivery points where video isn’t essential.

Multiple entrances & buildings

Many education sites have more than one building or access point. We can help design door entry that supports:

  • separate panels for different entrances
  • clear labelling and call routing
  • reliable operation across the site

Staff-only doors and restricted areas

Door entry can support controlled access to:

  • staff entrances
  • admin offices
  • IT/server rooms
  • stores and equipment rooms
  • caretaker and plant areas

Door Release, Maglocks, and Secure Hardware

We can supply and install the correct locking hardware for controlled entry, including:

  • electric releases / electric strikes
  • magnetic locks (where appropriate)
  • push-to-exit and request-to-exit devices
  • compliant egress solutions (confirmed at survey)

Upgrades and Replacments

If you already have an intercom/entry system, we can often:

  • repair faults (audio issues, door release problems, power faults)
  • upgrade older panels/handsets for better reliability
  • improve video quality and night performance
  • take over maintenance for existing systems

Maintenance and Fault Support

Door entry systems are used constantly — so reliability matters. We offer maintenance and responsive support to keep:

  • call quality clear
  • entry panels working
  • door release functioning correctly
  • permissions and user lists up to date

Why Schools and Colleges choose Door Entry

  • Supports safeguarding: controlled access at key entrances.
  • Better visitor management: verify and direct visitors before entry.
  • Reduces disruption: reception can manage access without leaving the desk.
  • Improves site security: helps prevent unauthorised access through side doors.
  • Clearer processes: consistent entry routine for staff and visitors.
