Access Control Systems
Control who gets in, when they get in and what areas they can reach.
BM Security installs practical Access Control Systems for homes, shops, offices and light industrial sites in Leatherhead, Southampton, Crawley and the surrounding areas. Systems are chosen to suit the building, the number of users and the level of security required, with clear handover documentation so you can manage day-to-day access with confidence.

What access control delivers for you
An effective access control system reduces the chance of unauthorised entry, gives a record of who used which doors and when, and makes key management far simpler. For businesses that need to protect stock, restrict staff-only areas or meet insurance conditions, a correctly specified system pays for itself in fewer security headaches.
Typical benefits include:
-
Precise control over who can open specific doors
-
Time restrictions so access can be limited to working hours
-
Audit trails and event logs that support investigations and insurance claims
-
Removal of mechanical key duplication risks by using coded cards, fobs or credentials
-
Integration with alarms and CCTV so a single incident triggers appropriate responses

Types of Access Control Systems available
Keypad systems
Simple and cost effective for small sites or single-door control. Codes can be changed quickly if compromised.
Mobile credential systems
Use secure apps so authorised users open doors with a phone. Useful where issuing physical cards is impractical.
Intercom and door entry
Audio or audio-visual entry systems for reception areas and communal buildings. These can link to access control for visitor release.
Networked controllers
Centralised management for multi-door or multi-site installations, including remote user administration and reporting.
Card and fob systems
Scalable for multiple users and doors. Access permissions can be changed centrally without changing locks.
Biometric readers
Fingerprint or facial recognition for higher security areas where personal identification is required.
Standalone door controllers
Cost effective for individual doors with local control.
Systems can be completely wired, wireless or a hybrid depending on building fabric, budget and desired reliability.
How a typical project works
Straightforward, transparent steps from initial enquiry to project completion.
1. Initial call and briefing
A quick conversation identifies the basic need. For straightforward single-door installs an on-site visit might not be necessary. For larger systems a site survey is arranged.
3. Proposal and quote
A written proposal outlines the recommended system, costs, installation timescale and any civil works such as cabling or door modification.
5. Handover and training
You receive clear instructions on managing users and a demonstration of the system. Written start up documentation and user guides are supplied where relevant.
2. Site survey and risk review
Engineers assess doors, frames, power availability and user flows. Existing hardware and escape routes are reviewed to ensure any solution is compliant with safety and fire regulations.
4. Installation and testing
Work is planned to minimise disruption. Engineers install hardware, configure permissions, integrate with CCTV or alarms if required, and test all functionality.
6. Aftercare and maintenance
Ongoing support and maintenance packages keep the system reliable and the logs available when needed.
Integration with CCTV, alarms and locks
An access control system should not sit in isolation. Linking access control to CCTV means an entry event can pull up live or recorded footage of the door area. Connection with an alarm system can trigger a wider security response if an authorised entry does not occur as expected.
If existing locks, electric strikes or maglocks are already fitted, engineers will advise whether the current hardware can be adapted or whether upgrade is necessary to meet safety and insurance requirements.
Who benefits most
Access control is useful for many situations, including:
​
-
Offices that need to restrict internal areas such as server rooms or finance offices
-
Retail units and warehouses that require stockroom control and signed-in contractor access
-
Landlords and managed blocks that need secure communal entry and visitor management
-
Schools, nurseries and clinics with zones that require differing levels of security
-
Light industrial sites where staff and delivery areas must be separated
​
If you manage multiple properties, central management and scheduled reporting make user administration far easier.
Reliability, standards and insurance
Choosing appropriate hardware and correct installation reduces the chance of failures. Engineers select products with suitable life expectancy and manufacturer support. For insurance purposes, mention any specific lock or cylinder standards when booking the survey so the right components and paperwork can be supplied.
Safety considerations such as emergency egress, fire door compatibility and door closers are assessed at survey. Access control must secure the building without placing users at risk.
Maintenance and support
Like any electromechanical system, access control benefits from regular checks. Typical maintenance options include:
-
Scheduled health checks and firmware updates
-
Battery and power supply tests for readers and controllers
-
Log backups and event archive management
-
Rapid fault-finding and replacement of failed components
A maintenance agreement keeps the system performing and reduces reactive callouts.
Cost and budgeting
Costs vary with door numbers, level of integration and the type of readers chosen. Simple single-door keypad installations are comparatively inexpensive. Networked systems with biometric readers and integration to CCTV represent a larger investment but deliver more control and audit capability.
A site survey provides a clear written quote and scope so you can compare options and make an informed decision.
