Access control and door entry in London

Manage who can enter your premises without making everyday access unnecessarily complicated. North London Alarms and Security supplies and installs access control and door entry systems, from a single controlled entrance to networked systems for business premises.

Start with the entrance and how it is used

A useful access control proposal starts with the people using the building. Staff arriving early, visitors attending appointments and deliveries arriving during the working day may all need different arrangements. Tell us where entry is currently difficult to manage, whether keys are frequently shared and which areas should remain private.

We focus primarily on North London, with enquiries also welcomed from East and Central London. Our head office is on Chatsworth Road in Hackney. Share your postcode and a brief description of the premises so we can discuss the installation and establish whether a quotation can be prepared by phone or a site survey is needed.

Single-door and networked access control

A single-door system can be suitable where one entrance needs controlled access. A networked system may be more appropriate when several doors and users need to be managed together. The choice depends on the size of the premises, the required permissions and how the system will be administered after installation.

Cards, fobs or other credentials may be available depending on the equipment selected. Discuss how new users will be added and how access will be removed when someone leaves. A clear handover matters: the person managing the system should understand routine changes, lost credentials and who to contact if an entrance stops working as expected.

Audio and video door entry

Door entry lets an occupant communicate with a visitor before deciding whether to release the entrance. Audio and video options serve different needs. Consider where calls need to be answered, whether seeing the visitor would help and how deliveries are handled when the usual contact is unavailable.

For shared entrances, the arrangement needs to reflect the people responsible for the building. We will discuss the proposed equipment, the position of internal units and any existing wiring that may be usable. Remote answering should only be assumed where it is included in the agreed specification and supported by the selected system.

Planning an installation around your premises

Door construction, frame condition, cable routes and available power affect the installation. An electronic system cannot compensate for a damaged door that does not close properly. Let us know about recurring problems with closers, locks or hinges so they can be considered before equipment is selected.

If the entrance is shared or the premises are leased, establish who can authorise changes. Where access arrangements affect escape routes or fire doors, the proposal needs appropriate coordination with those responsible for the building and its fire safety arrangements. These details should be resolved for the specific premises rather than inferred from a product description.

Working alongside alarms and CCTV

Access control manages entry permissions. An intruder alarm detects events within its specified coverage, while CCTV provides views and recordings of selected areas. Each has a separate role, and an installation should explain what each system is expected to achieve.

Our burglar alarm installation and CCTV services can be discussed alongside your door entry requirements. Integration depends on compatibility and the agreed design. We will not assume that an existing alarm, camera or door controller can be connected simply because it is already installed.

From initial enquiry to installation

Contact us with your postcode, property type, number of entrances and a description of the access problem. Photographs or details of existing equipment can help the initial conversation. We determine whether there is enough information to quote over the phone or whether a free site survey is required.

You then receive a tailored quotation explaining the proposed work. Once you are happy with it and agree to proceed, we arrange installation. Discuss working hours, visitor access and any entrances that must remain available during the work. The handover should cover everyday operation and the responsibilities of whoever will manage the system.

Your questions answered

Frequently asked questions

Can you install access control for just one door?

Yes, single-door installations can be discussed as well as networked systems. The entrance, its usage and the preferred way of managing users determine the proposal.

Can you upgrade an existing door entry system?

We can discuss an upgrade, but the existing wiring, equipment and door hardware need assessment. Compatibility and condition determine what can be retained.

Do I need a survey before receiving a quotation?

Not always. We first review your enquiry and determine whether we can quote by phone. If more information about the premises is needed, we can arrange a free site survey.
