Smart Gates in London — How App-Controlled Driveway Gates Actually Work

NOVA Gates & Railings has been installing smart gates across South West London since smart access systems became a practical and affordable option for residential properties. We hold CAME approval and install CAME Connect smart gate systems on residential and commercial properties across SW and KT postcodes as a standard part of our electric gate service.

This guide explains how smart gates actually work not the marketing version but the technical reality so you can make an informed decision before you speak to any installer.

What Is a Smart Gate?

A smart gate is an electric driveway gate fitted with an access control system that goes beyond a standard remote handset. At its most basic, a smart gate can be opened from a phone app from anywhere in the world. At its most advanced, it incorporates automated opening when your car approaches, video verification of visitors, temporary access codes for individuals, a log of every gate operation, and integration with your home security or smart home system.

The gate itself the structure, the motor, the safety devices is identical to a standard electric gate. What makes it smart is the control layer added on top of the motor system. That control layer can be added at the time of installation or retrofitted to an existing electric gate in most cases.

GSM vs Wi-Fi – The Two Main Systems Explained

This is the question that creates the most confusion for London homeowners researching smart gates, and the answer matters practically because the two systems work differently, have different dependencies, and suit different properties.

GSM Smart Gate Systems

GSM stands for Global System for Mobile Communications, the same technology used by mobile phone networks. A GSM gate controller contains a SIM card. When you open your gate from your phone app, the command travels from your phone over the 4G mobile network to the SIM card in the gate controller. The controller receives the command and activates the gate motor. The whole sequence typically takes two to four seconds.

The key advantage of a GSM system is that it operates independently of your home Wi-Fi or broadband connection. The gate communicates directly with the mobile network. If your router goes down, your broadband fails, or you are away from home, the gate still works. For a London property where the gate needs to be reliably accessible for deliveries, housekeepers, and other visitors regardless of the home network status, GSM is the more robust choice.

The cost of running a GSM gate system involves a SIM card with a data allowance. In practice, the data consumption of a residential gate system is minimal; gate operations use very small data packets and a basic SIM plan costing a few pounds per month is sufficient for most residential installations. Some CAME Connect subscriptions include the data cost within the service package.

GSM systems also support a simple “dial to open” function where calling the SIM card’s number from an authorised phone number opens the gate; no app required, no data needed, just a phone call. This is a useful backup for visitors who may not have the app installed.

Wi-Fi Smart Gate Systems

Wi-Fi gate systems connect the gate controller to your home broadband router. Commands from your phone app travel over the internet to your home router and from there to the gate controller via a cable or short-range Wi-Fi link at the property.

The advantage of Wi-Fi systems is that they can offer faster response times and more advanced features including real-time video integration with doorbell cameras, tighter smart home platform integration, and in some systems a virtual gate status display showing whether the gate is currently open or closed.

The practical limitation is dependency on the home broadband connection. If the router is offline, the gate cannot be operated remotely via the app. For properties where consistent remote access is important and for most London households with regular deliveries, visitors, and multiple drivers, it is this dependency is worth factoring into the decision.

The CAME Connect system, which we install as part of our CAME-approved service, supports both GSM and Wi-Fi connectivity. Properties can be configured to use either or both, with GSM as a fallback when Wi-Fi is unavailable.

Bluetooth Access

A third connection option, Bluetooth, is available on some systems including certain CAME Connect configurations. Bluetooth works at short range typically up to 30 metres and allows your phone to automatically detect the gate as your car approaches and open it without any manual input.

Bluetooth proximity opening is a genuinely useful feature for daily home access. As your car pulls into the road outside your Wimbledon or Clapham property, the gate detects your phone and opens before you reach it. The limitation is range it only works when you are physically close to the gate which is why Bluetooth is typically used alongside GSM or Wi-Fi rather than as a standalone system.

The CAME Connect System – What It Does and How It Works

NOVA Gates & Railings installs CAME Connect as our standard smart gate system because CAME is the automation brand we are approved to install and the system integrates reliably with the CAME motor range we use on residential and commercial gate projects.

CAME Connect is a cloud-based access control platform. The gate motor connects to the cloud through a CAME Gateway device a small module that plugs into the motor control board. Once connected, the gate is accessible through the CAME Connect app on any smartphone or tablet.

What the CAME Connect system allows:

Remote operation. Open or close the gate from any location with a 4G or Wi-Fi connection. There is no geographic limit the system works from anywhere in the world.

Multiple users. The gate owner can create individual app access profiles for family members, housekeepers, cleaners, gardeners, and regular visitors. Each user has their own account and their own access record.

Temporary access codes. Time-limited access can be granted to a visitor for a specific date and time window a delivery driver arriving on Tuesday between 2pm and 4pm, a contractor working for three days next week, an Airbnb guest arriving Friday evening. When the time window expires, access is automatically revoked.

Activity log. Every gate operation is recorded who opened it, at what time, by which method (app, remote, keypad, dial-to-open). For a family home with multiple users or a property managed remotely, this log is a practically useful security tool.

Scheduled operation. The gate can be programmed to open and close automatically at set times useful for commercial properties with defined access hours or for residential properties where the gate should always be closed by a certain time of evening.

Notifications. Push notifications can be sent to the owner’s phone whenever the gate is operated, or specifically when it is opened by a non-regular user. For a homeowner who travels frequently, knowing the gate has just been opened while the property is supposed to be empty is a relevant security alert.

Video Intercoms and Smart Gate Integration

The most useful pairing with a smart gate system is a video intercom at the gate post. A visitor approaches the gate, presses the intercom call button, and the homeowner receives a video call on their phone from anywhere showing a live view of who is at the gate. The homeowner can speak to the visitor and open the gate from the phone with a single tap.

This combination smart gate plus video intercom is what replaces the need to be physically present at the property to manage access. For London homeowners who travel frequently, work long hours, or manage a property remotely, it is a significant practical benefit.

CAME produces a range of video intercom systems that integrate directly with the CAME Connect platform, so gate operation and visitor video are managed through the same app. Third-party intercoms and door cameras including Ring, Hikvision, and 2N can also be integrated alongside CAME Connect gate systems, though the level of integration varies by product.

For properties where the gate is set back significantly from the road, the intercom post at the gate entrance needs a cable run back to the house for power and signal. This cable run is part of the groundwork and electrical installation when the gate is installed retrofitting it later is possible but adds cost. If there is any chance you will want a video intercom, it is worth specifying the conduit for the cable during the initial installation.

ANPR – Automatic Number Plate Recognition

ANPR (Automatic Number Plate Recognition) is the premium option for smart gate access and is increasingly specified on higher-end residential properties in London. An ANPR camera at the gate entrance reads the number plate of approaching vehicles and opens the gate automatically for recognised plates, without any interaction from the driver.

The practical benefit for a family home is obvious. You pull up to the gate in your car, the camera reads the plate, the gate opens. No phone required, no remote to find, no pause. For a household with two or three cars all using the same entrance regularly, ANPR reduces every gate interaction to zero effort.

ANPR cameras for residential gates typically cost between £1,500 and £3,500 installed depending on the camera specification, the processing unit, and the number of vehicle profiles being managed. The camera needs a clear sightline to the approaching vehicle’s number plate, which affects where it can be mounted. On gated driveways with a straight approach, this is straightforward. On curved approaches or properties where vehicles approach from an angle, the mounting position needs to be considered during the site survey.

What Happens During a Power Cut?

This is one of the most common practical questions about smart gates and the answer is reassuring.

Modern CAME gate motors include a battery backup system as standard. The battery maintains gate operation through most domestic power cuts without interruption. If the power is out when you arrive home, the gate still opens normally from your phone or remote because the motor is running on battery power.

If the battery is also exhausted which would require a prolonged power failure — all professional gate motor systems include a manual release mechanism. This allows the gate to be disconnected from the motor and opened by hand. The manual release location and operation is demonstrated at handover on every gate installation.

The smart app system itself CAME Connect continues to operate normally during a power cut at your property because it runs on cloud infrastructure. The gate motor and controller are running on battery backup. The cloud system is unaffected. The only thing that would prevent remote operation during a power cut is if the battery backup is also depleted, in which case the manual release is the answer.

Smart Gate Costs in London

The cost of adding smart access to an electric gate installation in London varies depending on the system specified.

These costs are in addition to the base electric gate installation. For a full breakdown of electric gate costs in London, see our electric gates cost guide and driveway gates cost guide.

Can Smart Access Be Added to an Existing Electric Gate?

Yes, in most cases. If your current electric gate has a CAME motor or a compatible control board, a CAME Connect gateway can be added to the existing installation without replacing any of the gate structure or motor. The gateway module connects to the control board and the system is operational within a day.

For gates with older or non-CAME motors, compatibility depends on the control board. A site visit and inspection of the existing installation is the right starting point. Most professional gate motors from the last ten years can be integrated with a smart access system of some kind, though the level of integration and the features available will vary.

Smart Gates in South West London – Where the Demand Is Strongest

NOVA Gates & Railings installs smart gate systems regularly across the SW and KT postcode areas, and the demand profile is consistent with what you would expect given the property mix.

In Wimbledon Village, Kingston Hill, and the Coombe Estate, large detached and semi-detached properties with multiple regular users family members, housekeepers, gardeners, contractors benefit most from the multi-user access management and ANPR options that smart systems provide. These are also properties where the homeowner is more likely to travel regularly or manage the property remotely.

In Clapham, Tooting, Raynes Park, and the denser Victorian terrace areas, the primary driver is usually delivery management and visitor access rather than multi-car ANPR. Smart intercoms that allow residents to see and speak to visitors and grant access from their phone are the most commonly specified addition in these areas.

For commercial properties along the main arterial roads through Wimbledon, Putney, and across the KT postcodes, scheduled opening, activity logging, and coded access for staff are the features that matter most.

Under HSE guidelines for powered gate installations, all electric gates smart or otherwise must include safety photocells, safety edges, and a force compliance test at handover. Smart technology does not change the safety requirements. We include all safety compliance documentation as standard on every installation.
