Intercom & Door Entry Solutions for Public Sector & Local Government Buildings in Surrey


Audio and video entry systems for council and public sector sites — designed for controlled entry, visitor management and day-to-day reliability.


Public sector buildings often have high footfall, multiple user groups, sensitive areas, and clear procedures for visitor access. You need door entry that’s reliable, easy for staff to use, and suited to the way the building operates.


OC Services designs, installs and maintains intercom and door entry systems for local government and public sector buildings across Surrey, including council offices, depots, libraries, community hubs, leisure facilities, civic buildings, and other public-facing sites.


Whether you need a simple audio intercom for a staff entrance or a video door entry system for a controlled access point, we’ll recommend a solution that fits your site layout and operational requirements.

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 (reception, 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)

Ideal where staff need to visually verify visitors before granting access. Systems can be specified to support:

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

Audio intercom (simple, robust entry control)

A great option for side doors, volunteer entrances and delivery points where video isn’t essential.

Reception & visitor management

Door entry can support smoother visitor handling by allowing reception teams to verify and grant access without leaving the desk.

Staff only areas and restricted access

Door entry can help control access to:

  • staff-only corridors and offices
  • records/storage rooms
  • IT/server rooms
  • plant rooms and comms rooms
  • depots and back-of-house entrances

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/door entry system, we can often:

  • diagnose faults (audio issues, door release problems, power faults)
  • upgrade older panels/handsets/monitors
  • improve video quality and reliability
  • 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 Public Sector Sites choose Door Entry

  • Controlled entry — manage public access without disrupting operations.
  • Improved visitor handling — verify visitors before granting access.
  • Better protection for staff-only areas — reduce unauthorised access.
  • Practical day-to-day reliability — robust systems for busy buildings.
  • Clearer processes — consistent entry routine for staff and visitors.
