Types of Intruder Alarm Systems

Alarm System Hubtech

Did you know that you can easily deter intruders from your home by installing an alarm system? It works in two ways. Firstly, it can prevent intruders from getting into your home. Secondly, an intruder alarm will make criminals flee the crime scene when they trigger the alarm. Even though there are many types of alarm systems, the type you choose depends on the level of security you want to achieve. Importantly, the cost of an alarm system will play a very important role in the choice you make. Also, put into consideration the kind of response you will get from the police when the alarm goes off. Alarm systems also tend to affect the amount you pay in terms of insurance premiums. So, you must pay that into consideration when choosing an alarm system.

The following are the types of alarm systems you are likely to get on the market.

1. Wired Intruder Alarm Systems

The word “wired” implies that these alarm systems are connected using hard wires. They rely on low voltage electrical circuits that connect two points in the windows and doorways in the home. Once you shut the windows or doors, the electric current gets to flow easily. Any action of opening the window or door disrupts the circuit and, in the process, triggers the alarm. Pros

  • Wired intruder alarms provide reliable monitoring since they do not rely on sensors that rely on radio frequencies to operate. The system can only be disrupted when the wiring gets damaged or the phone line is snipped. So, you can expect the alarm system to keep working for as long as possible.
  • The systems are also easy to maintain. Once you have done the initial setup of the system, you don’t have to worry about additional maintenance such as regular battery change.
  • Wired intruder alarm systems can accommodate a number of sensors, making them suitable you use in large spaces. Also, they can be used in multiple buildings.
  • To prevent hacking into your intruder alarm system, use a wired one. For someone to access the system, he or she will have to directly connect to it.


  • One of the main disadvantages of wired intruder alarm systems is that they are more expensive to install. The work involved is tedious since you have to connect sensors using low-voltage wires inside the walls. You must just drill holes to access the wires.
  • The systems are more vulnerable since all an intruder needs to do to interrupt them is cut the phone lines to the house.
  • Because of their permanence, uninstalling wired intruder alarm systems might prove to be difficult. That’s why moving old equipment to a new location may prove impossible.

2. Wireless Intruder Alarm Systems

Alarm System Hubtech Wireless intruder alarm systems are just that. They are connected without using any wires. Wireless alarm systems rely on a control panel to connect several sensors connected to built-in transmitters of radiofrequency. When the alarm system is triggered, it transmits a signal to the control panel and, in the process activates the alarm. Pros

  • Quick to install. The installation of wireless intruder systems equipment is easy. You don’t have to grapple with drilling and tricky wiring. Since they can be installed as DIY, the cost of installation.
  • Easy to remove. Basically, you don’t need to rip wires out of the walls or rely on professionals to uninstall the systems. If you are renting office space, moving to brand new premises is easier with these systems.
  • Wireless. Due to their wireless nature, these intruder alarm systems are not easy to disrupt. After all, they do not have wired phone lines which can be vandalized.
  • Simple to modify. Since it is not hard-wired, a wireless phone system is easy to upgrade and modify. You can easily remove and add sensors to the system.
  • It can be accessed remotely. In a wireless system, there is a remote key fob whose work is to arm or disarm the system. Thus, you can use it to trigger the panic button in an emergency. Since they rely on wireless connectivity, it is possible to activate the function using a mobile phone. In fact, you can set the basic functions of the system using a smartphone.
  • Part of the home automation system. It is easier to sync a wireless intruder alarm system with other features in the home. Thus, you can easily upgrade or downgrade the system by adding a smart thermostat, smart locks, and smart lights.


  • Likely to be interfered with. Since they rely on radio waves, which is similar to Wi-Fi, they can easily be interfered with. Simple things such as power lines and remote controls can interfere with wireless systems by introducing electromagnetic waves. Also, radio frequencies could be blocked by obstacles like metal filing cabinets and walls.
  • Battery operated. Since they are battery-operated, you have to keep checking wireless intruder alarm systems to see if they are still working. When the batteries run out, you will be forced to replace them.
  • Limited reach. By their nature, wireless networks have a limited reach and are best suited for small to medium-sized offices and homes. Most won’t transmit radio waves beyond a 500-foot radius.
  • Hacking risk. When intruders hack into the wireless intruder alarm systems, they can jam or interfere with the signals to ensure that the alarm doesn’t set off. That’s why it is important to consider how secure a security system is before buying it. Apart from having a strong password, use encryption to ward off hackers.

Whether you have a wired or wireless intruder alarm systems, you need to be sure how you are going to contact the authorities when there is an emergency. Thus, you could have an unmonitored system which will trigger an alarm before someone nearby notifies the nearest monitoring center. The only advantage of these systems is that they are cheap. Alternatively, you may want a monitored intruder alarm system which alerts the monitoring center where there is an emergency. When they receive the signal, the operators at the emergency center will send the necessary personnel.
