Intercom & Door Entry Solutions for Industrial Properties in Surrey


Audio and video entry systems for warehouses, factories and industrial sites - designed for high-use entrances, deliveries and controlled access.


Industrial sites need access systems that are reliable, robust and practical. Staff entrances, trade counters, loading bays, roller shutter doors, side gates and shared yards all create opportunities for unauthorised access, and they're often the exact points that slow operations down when entry isn't managed well.


OC Services designs, installs and maintains industrial intercom and door entry systems across Surreyfor warehouses, factories, workshops, depots, distribution centres, plant rooms and multi-tenant industrial units.


Whether you need a simple audio intercom at a staff entrance or a video door entry system for a controlled access point, we'll specify a solution that suits your site layout, working hours and security 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 (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)

Ideal for entrances where you need visual verification 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 + manager office)
  • secure door release (electric strike/maglock) where appropriate

App-enabled answering (where suitable)

For some sites, app-enabled systems allow authorised managers to answer calls remotely (useful during busy service). We’ll confirm suitability at survey.

Audio intercom (simple, robust entry control)

A cost-effective option for staff doors, side gates and delivery points where video isn't essential.

Staff entrances & back-of-house access

Door entry can help control access to:

  • staff-only doors
  • offices and admin areas
  • stores, cages and stock rooms
  • plant rooms and comms rooms
  • cash-handling or high-value storage areas

Loading bays, yards & delivery management

Intercom at delivery points can reduce disruption by allowing teams to verify visitors and direct deliveries without leaving the floor.

Multi-tenant sites and shared entrances

For industrial estates and shared buildings, we can help design door entry that supports:

  • separate tenant answering points
  • clear call routing and labelling
  • controlled release for shared doors (where appropriate)

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 Industrial Sites choose Door Entry

  • Controlled entry: manage access to staff-only and restricted areas.
  • Reduced tailgating risk: support better access discipline at key doors.
  • Smoother deliveries: handle suppliers and visitors efficiently.
  • Improved site safety: reduce unauthorised access to yards and plant areas.
  • More accountability: support incident review at access points.
