Alarms East Sussex

Established 1999 | Over 30 years of industry experience

There are few things as frightening as the thought of an intruder in the place you usually feel safest. Domestic burglary continues to rise throughout East Sussex, with a creeping average of 500 reported each month. According to police.uk unsecured homes are five times more likely to become victims of break-ins and burglary. That’s why we focus on visible security measures that act to prevent and deter criminals.

Hallmark Security are a family run, independent business supplying homeowners throughout East Sussex with complete alarm and CCTV security systems from leading suppliers since 1999. With over 30 years of industry experience the business offer a huge range of high quality, independently sourced products from a range of manufacturers.

As the only security alarm system specialist dedicated to residential properties in East Sussex, our experienced staff have a deep understanding of the industry and of the specific requirements for domestic properties, installing all systems in accordance with BSEN50131. Based in Newhaven, we cover East & West Sussex, Surrey, West Kent & East Hampshire and offer a 24-hour call out repair service to our contracted customers.

Because we’re completely independent, any solution recommended by Hallmark is absolutely tailored to the needs of our customer and their property and never to the supplier. While we specialise in the installation and maintenance of wireless residential burglar alarm systems from leading suppliers Texecom & Pyronix, we have access to the whole security market and will always select the most appropriate system for your needs absolutely without bias.

Texecom's revolutionary Ricochet Wireless Technology utilises mesh networking wireless technology to deliver more performance than any other wireless security system with multiple devices capable of relaying messages to and from each other allowing great coverage and scalability.

Pyronix offer the multi-award-winning Enforcer two-way wireless technology system. With great battery life and reliability these devices are perfect for ensuring the security of your home.

For absolute protection, we partner with Yeoman Monitoring Services to supply and install instant response alarm signalling systems from BT Redcare and Dualcom. These always-listening technologies relay alerts using phone lines and mobile networks for an immediate response to suspicious activity.

With so many intruder alarm methods and systems available, without professional advice it’s tempting to allow your budget to make the decision for you. When you speak to Hallmark Security, we’ll arrange a visit to complete a survey at your home, so we can understand your exact requirements. We’ll explain how an intruder might gain access and recommend the best solution to prevent break-ins. Our experienced, approved installers will always recommend a solution best-suited to your home, your circumstances and to your budget.
