Wired or Wireless?

J-Sec recommends wired intruder alarm systems as the best solution for medium to large commercial premises. Each specialist detector and warning device is connected to the main system and powered by copper cabling.

Wired systems can be installed in Grade 2 or Grade 3 levels depending on insurance requirements.

In contrast, wireless intruder alarm systems are best suited to domestic and small commercial installations. This is largely due to their straightforward and hassle-free installation.

The wireless alarm system's highest attainable grade is 2.

If you’re still feeling unsure as to whether a wired or wireless alarm system is better suited to your situation, contact the team at J-Sec. We will be happy to discuss your requirements and make the decision-making process a lot less painful.

Wired Intruder Alarm Systems

Intruder alarm systems that are hard-wired can generally be considered as having increased reliability. Alarms of this variety are often equipped with a central back-up battery, this is a precautional method taken in case of a power outage.

Wired burglar alarms typically offer more versatility, they allow any device or feature to be added simply by wiring it into the system.

Alarm systems of this design generally require professional installation.

Wireless Intruder Alarm Systems

Wireless intruder systems are typically less troublesome and quicker to install. Removing the wired element means there is no need for the running and hiding of cables. Wireless burglar alarms operate by sending signals from the detectors to the control panel, this, in turn, triggers an alarm.

Another benefit of installing a wireless burglar alarm is that they can be moved with minimal effort, this means moving home or renovation work can take place without the problematic need for rewiring the alarm system.

We offer burglar alarm installations in Bridgend, Cardiff, Swansea, Vale of Glamorgan, Rhondda, Merthyr, Brecon, Bristol, Somerset, London, Coventry and nationwide

Monitored Alarm

Several options are available for monitoring an intruder alarm system, from a dialler that can call your mobile directly using your landline, to a 24/7 monitored system connected to a remote monitoring station.

J-Sec are able to source systems that are smartphone compatible. This type of burglar alarm is becoming increasingly popular, allowing the user to remotely monitor their burglar alarm using their mobile phone, or another smart device with an internet connection.

Bells-Only Alarm

In contrast to a monitored alarm, a bells-only alarm is not connected to any form of monitoring system, its only function is to sound an external siren. As a result of its reduced service, a bells-only alarm is usually the least expensive and consequently most popular option for the average homeowner.

A bells-only alarm installation relies solely on the assumption that people within the locality will respond to the siren. As such, a bells-only burglar alarm is appropriate for heavily populated neighbourhoods, that are likely to employ a neighbourhood watch scheme. It is expected other residents in neighbourhoods of this variety will respond to the alarm siren, contacting either the homeowner or the emergency services.

However, if your home or business resides in a remote location it is unlikely your alarm siren will be effective as there are little, or no, residents within your local vicinity. This means that in the unfortunate event of a break-in, it is unlikely your siren will be reported to the emergency services.  

Whilst a bells-only alarm might be considered useless as the system relies solely on third party reporting, this type of alarm system does still serve as a visual deterrent and a distress signal. A bells-only alarm system also provides a budget-friendly security solution.    

Commercial Alarm Installation

Here at J-Sec we understand that securing your business and its assets is vital in ensuring your livelihood is protected. That’s why we recommend intruder alarms of only the highest efficiency.

One of our commercial intruder alarms can help to deter thieves and minimise the risk of trespassing. In the unfortunate event of a break-in, our intruder alarm systems will alert the relevant authorities and drastically reduce the amount of time the thief has to navigate your business premises and its possessions.

Domestic Alarm Installation

It is recommended that homeowners install an intruder alarm system as a means of deterring crime and preventing burglary. Intruder alarm systems have proven beneficial in protecting not only your property and its possessions, but also the people you hold closest.

J-Sec can install alarm systems tailored to compliment your home and adapt to your budget. Solutions we offer include bells-only systems, motion detectors and monitored systems.

Contact us to discuss your requirements, and we’ll help design a suitable and secure alarm solution for you.

Benefits of a burglar alarm

There are numerous advantages associated with the installation of an effective burglar alarm system. Needless to say, the most dominant advantage is that of protecting a specific property against intruders and deterring crime.

An additional advantage of an efficient burglar alarm installation is that of 24-hour protection. An alarm removes the need for increased manpower, a breach of security will alert the relevant personnel to any unauthorised access.

Installation of an intruder alarm can also result in reduced insurance costs; this additional measure of protection can decrease your premiums.

Lastly, and often the most overlooked, benefit associated with the installation of a burglar alarm is the peace of mind. When leaving your property unmanned for long periods of time you can relax in the knowledge that your burglar alarm is working 24/7, protecting your home against any uninvited visitors.

Louise Cormack


Excellent, quick, communicative service. James took my call over the weekend answering my request for help with a faulty home security alarm in Bridgend. As it wasn't an emergency he then attended on Monday and efficiently checked the functions and offered great sensible advice. He was understanding and caring of the elderly owner and was very good communicating with me at a distance.

I was impressed with the kind service.

Alex Howells


I initially used J Sec Security for a home installation that was carried out to the highest of standards by polite professional employees, after seeing how good the company and the standard of work was I then used them again for a business that needed cameras as well as access doors. They could not have been better, from advice to fitting as well as ongoing customer care!

Would 100% recommend.
