Intercom & Door Entry for Commercial Properties in Surrey


Audio and video entry systems for offices, shops and commercial buildings — specified for secure access and smooth visitor flow.


If you manage a commercial property, the front door is a security point and a customer experience touchpoint.


OC Services designs, installs and maintains intercom and door entry systems across Surreyfor offices, retail units, business parks and multi-tenant buildings — helping you control who comes in, reduce unauthorised access, and make it easy for staff to admit visitors and deliveries safely.


We focus on systems that work day-to-day: clear audio/video, reliable door release, sensible user permissions, and a setup that fits how your building actually operates.

Our Commercial Door Entry Solutions

Survey, Design & Installation

We start with a site survey to confirm:

  • how visitors arrive (reception, shared entrance, rear delivery 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 Systems

Ideal when you want visual verification before granting access — useful for:

  • offices with visitor traffic
  • trade counters
  • shared entrances
  • out-of-hours deliveries (where appropriate)

Audio Door Entry Systems

A practical option for many commercial sites where video isn’t required, especially for:

  • staff entrances
  • internal doors
  • service entrances

Multi-tenanted Door Entry systems

For managed buildings and multi-occupancy commercial sites, we can specify systems that support:

    • multiple units/tenants
    • clear call routing
    • controlled admin access
    • straightforward onboarding/offboarding of users

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 have an older or unreliable system, we can often upgrade without reworking everything. Common improvements include:

  • clearer audio/video
  • better reliability on door release
  • improved user management
  • replacing damaged entry panels/handsets
  • integrating door entry with access control

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

Typical Scenarios

  • Secure visitor entry without disrupting staff
  • Reception-based answering or routed to key staff
  • Controlled staff access
  • Controlled rear/service entry
  • Clear communication for deliveries
  • Clear responsibility for admin/user management
  • Reliable door release and robust entry panels
  • Call routing to the right tenant
  • Scalable system for additions /changes
