CCTV Camera Installation

Installing a robust CCTV network begins with understanding exactly what needs to be watched. Our team conducts a full site assessment—pinpointing entry points, high-value areas, and potential blind spots. We then recommend the ideal cameras, whether high-resolution fixed domes for front doors or vandal-resistant PTZ units for large outdoor spaces. Each camera is wired into a central recorder that stores footage on secure hard drives, and we configure motion triggers and retention schedules to match your needs.

Once the hardware is in place, we fine-tune every camera’s angle, focus, and field of view so there are no gaps in coverage. We also set up remote access via smartphones or computers, allowing you to check live or recorded video from anywhere. By embedding our CCTV camera installation service into your security plan, you gain real-time monitoring and clear evidence in the event of an incident.

Alarm System Installation

An alarm system serves as both a deterrent and an early-warning network. We mount magnetic contacts on every external door and window, and place motion sensors in key zones like hallways or stockrooms. All devices are wired or wirelessly linked to a central control panel, which can trigger an audible siren and send alerts straight to your phone or our dedicated monitoring station.

Our team configures each sensor’s sensitivity to avoid false alarms, and installs a communicator—either cellular or IP-based—to ensure signals go through even if lines are cut. We provide you with clear instructions on arming, disarming, and managing user codes. Integrating our alarm system installation ensures you’ll be notified instantly the moment any breach is detected, giving you time to respond or alert authorities.

Intercom System Installation

Intercoms add a human layer to your security setup, letting you see and speak with visitors before granting entry. We install outdoor panels at gates or front doors, complete with built-in cameras and speakers. Inside, we mount master stations with high-resolution video screens and door-release buttons. In multi-unit buildings, we can connect dozens of panels to a central console or smartphone app.

Our technicians handle every detail—from running cables and mounting panels to configuring door strikes and adjusting audio levels. We also offer wireless intercom options for sites where trenching or re-wiring isn’t practical. Adding our intercom system installation to your security solution lets you verify visitors visually and verbally, preventing unwanted access without ever leaving your desk.

Hear What Our Happy Clients Say About Us…

Just had some electrical work/ security camera set up done by Ethan, and I honestly couldn’t be happier. He was super efficient, really patient, and just overall great to work with. You can tell he knows his stuff and actually cares about doing a good job. What really stood out was the customer service — so friendly and easy to talk to. He took the time to explain what he was doing and made sure I was comfortable with everything. No rush, no pressure, just really solid work.

P.S  my dogs loved him

Anna - Kilsyth

Ethan fitted me into his schedule at short notice after we had an electrical fault emergency. Ethan was very knowledgeable and future safety was top of his list. He identified the issue immediately and fixed the damage it had caused and tested my appliance which put my mind at ease after quite a frightening experience. 5 stars, my go to electrician from now on

Debbie - Croydon

Had a great experience with Thomas Group Electrical. They were punctual, professional, and easy to deal with from the moment they arrived. They replaced a few outlets and carried out a full check of all the smoke alarms and sockets. The work was done efficiently, to a high standard, and they left everything neat and tidy. It’s reassuring to have tradespeople who are both reliable and respectful. I’d happily recommend them to anyone needing quality electrical work.

Angus - Mornington

Fast, friendly, and zero fuss. Ethan spotted an overloaded circuit I’d been ignoring for years and fixed it on the spot. Plus the bonus surge protector gives real peace of mind—no more worrying about storms frying my gear!

Melissa - Cheltenham

Ethan was incredibly thorough with our safety inspection—every circuit, outlet, and switch was checked from top to bottom. He installed the surge protection device in under an hour, and our home hasn’t tripped once since. Highly recommend Ethan’s service!
