MANAGED IT SERVICES · CCTV AND ACCESS CONTROL

CCTV and access control

Cameras, including AI-enhanced systems, door entry and intercoms designed, installed and supported by the team that looks after your network, for warehouses, venues, serviced office buildings and schools across London and Hertfordshire.

CCTV and door access are only as reliable as the network they run on. Because we install and look after networks too, your cameras, door readers and intercoms are designed as part of one system, not bolted on afterwards.

We prefer Ubiquiti’s UniFi range for cameras and access control, so everything is managed alongside your Wi-Fi and network in one place. We also install and support Hikvision and Paxton systems, and can work with what you already have.

What we install and support

CCTV cameras

Indoor and outdoor cameras placed to cover entrances, stock, tills and car parks, with clear images day and night.

AI-enhanced detection

AI-enhanced cameras that tell people and vehicles apart, so you get useful alerts instead of false alarms and can find the right footage in seconds.

Recording and viewing

Footage recorded on site and kept as long as you need, viewable on your phone or computer by the people who need it.

Door access control

Cards, fobs or phones to open doors, so you decide who gets in, where and when, and can remove access straight away.

Video intercoms

Intercoms at gates and entrances, so visitors and deliveries can be let in from a phone or reception.

One system, one team

Cameras, doors and network looked after together, with firmware kept up to date and faults fixed by the same team.

Built for busy sites

We install CCTV and access control for warehouses and industrial units, restaurants, bars and event venues, serviced office buildings, schools and offices. Work is planned around your opening hours, tenants or term dates, so disruption is kept to a minimum.

For one event production company, we installed more than 60 cameras, card-based door access and intercoms across a new warehouse, all managed from one app. Read the case study.

Frequently asked questions

Do you monitor our cameras?

No. We install and support the system itself: we keep the cameras recording, the storage healthy and the firmware up to date, and fix faults when they happen. Watching and reviewing footage stays with you and the people you choose.

What does AI-enhanced CCTV do?

AI-enhanced cameras recognise what they’re seeing, such as a person or a vehicle, rather than just movement. That means fewer false alerts from passing shadows or weather, and footage you can search by what happened instead of scrolling through hours of recordings.

Can you work with our existing CCTV or door access?

Often, yes. As well as Ubiquiti, we install and support Hikvision and Paxton systems, so we’ll look at what you have and suggest whether to keep, extend or replace it.

Can we view our cameras on our phones?

Yes. Live and recorded footage can be viewed from a phone or computer, with access limited to the people who need it.

Do we need to think about data protection?

Yes. CCTV records personal data, so you’ll need clear signage and a sensible retention period. We can set up retention and viewing permissions on the system to match your policy, and the ICO publishes guidance for organisations using CCTV.

Do you install CCTV in schools?

Yes. We plan school installations around term dates, and only DBS-checked members of our team are ever sent on site to a school.

I wanted to take a moment to recognise the outstanding work Brian did in successfully managing our network migration at CUBIX, Milton Keynes. From start to finish, Brian demonstrated exceptional professionalism, technical expertise and dedication. The migration of our internal clients was carried out smoothly and efficiently, with minimal disruption to our day-to-day operations. What impressed us most was the level of customer service and support he provided throughout the project. Brian gave each client personal attention, ensuring questions and concerns were addressed promptly and that everyone felt supported during the transition. His clear communication, patience and willingness to go above and beyond made a significant difference and contributed greatly to the success of the migration. A huge thank you to Brian for his hard work and attention to detail. Experiences like this confirm that we chose the right IT service partner - we would highly recommend their services to any organisation looking for reliable, professional IT support.
