Outdoor Detector

  • Catch intruder before an attack
  • Pet Friendly up to 20kg
  • Easy installation to any solid structure
  • Can be added to almost any existing alarm system


Catching the intruder before they can reach an entry point to your property makes sense. Our new Wireless Outdoor Detector can be fitted anywhere across the back or side of your premises to ensure any potential thief is caught in their tracks. The detector picks up any motion when the alarm is set, triggering the system and alerting you and your neighbours before an attack on your home can occur. This device can be fitted to any existing Orisec alarm system or added onto a current wired system, with a Wireless Receiver to allow for signalling. This device is also Pet Friendly, meaning any animals that enter your garden won’t be picked up, minimising the risk of false alarms.

Illuminated Siren

  • Audible and visual deterrent
  • 110dB siren (equivalent to a rock concert!)
  • Can be installed to any existing wired system
  • Doesn't affect electricity bills


Here at Nova, we always say that your external siren is arguably the most important part of your system. This is the only part of your system visible from your property's exterior. Ensuring your external siren is up to date and looks the part should be paramount to your security. Our new Illuminated Siren is a surefire way to ensure any potential burglars head in the opposite direction. A full centre plate is illuminated at night to give a vivid visual deterrent to potential burglars. We recommend your external siren is swapped every ten years, so if you go outside and think yours is looking a bit worse for wear, there's no better time than now to upgrade.

Smart Security App

  • App is completely free to use on as many devices as you like
  • No ongoing costs
  • Complete control over your security, from anywhere in the world
  • Ease of use of system




Now a common misconception is that you would have to have a completely new alarm to access something like this. This is not the case. If you have an existing wired alarm system, simply swapping out your main control panel and/or remote keypad can give you full access to the mobile app and its capabilities. This sort of package is probably more affordable than you think too. If you’re unsure if we can make this work for you, please get in touch with us, and we can talk you through the necessary steps to get you online.

Wireless Detectors

  • Easy installation, no mess or wires
  • Protect outbuildings and sheds easily
  • Array of different devices available
  • Can be added to any existing wired system


Wireless detection is now an industry standard for smart home alarm systems. The extra wireless capabilities allow for many more spaces that couldn’t have been alarmed to be protected in the future. That outhouse at the bottom of the garden? The man cave you built over lockdown? Or even just a part of the house you feel has been neglected all these years. It is now easier than ever to protect these spaces. A Wireless Receiver can be added to any existing wired system, adding functionality for either 1,5 or 10 devices. They come in various colours, too—black, white, brown and anthracite to suit any home aesthetic.

Wireless Detectors that we have available are:

  • PIRs for detecting the motion
  • Shock Detectors for detecting vibration (normally fitted to windows)
  • Magnetic Contact fitted to doors that see the opening or closing of the door
  • Shock & Magnetic Contact (dual device)
  • Outdoor Detectors for detection of your outside spaces

I needed a door contact re attaching, so I phoned Nova on the Friday afternoon, and they came out on the Monday and sorted everything out perfectly.Couldn't ask for a better and speedier service.Proper friendly too, everyone I spoke with. And they saved me a lot of money rather than going through the company who originally installed it, who wanted more than twice the price just to come out.Would definitely use again!

Had an alarm fitted last week due to a break in. Within 24 hours of making contact the work was quoted and alarm installed.Charlotte was great arranging the quote so quickly and very supportive. Checking in on me after the alarm was installed.Adam was great who quoted, discussed all options and saved me money in the process! I was going overboard wanting various things and he advised me with better options that saved money.Daryl who installed the alarm was very polite, professional and helpful. Also patient with me when it come to the technical demo. I'm not the best with technology!Great company, very professional and would definitely recommend to others.Thanks to all at Nova Alarms for making me feel safe in my own home again 🙂

Had an alarm system with nova now for about 10 years. I have just moved and they was my first choice again. The product, support and customer service is second to none. The support and customer service largely down to a fantastic lady called Charlotte who is always willing to go that extra mile. She is always friendly and helpful with no problem to big or to small. The companies great and she's an asset to them
