One of the principles of the classification of security alarm systems is the method of signal transmission. Based on this principle, two types of alarms are distinguished: wired and wireless. Both types are presented on the modern market by a wide selection of models. Accordingly, the buyer has a natural question: what kind of alarm system to prefer, wired or wireless.

If a few years earlier many would have recommended wired systems, due to the more attractive cost, increased level of reliability, and the possibility of installing sensors at a sufficiently large distance from the alarm control center, today wireless alarm systems have thoroughly "mastered" in the security market and is a full-fledged rival to wired models.

Of course, this is just a statement of fact that does not solve the problem of choice. But you need to make a specific decision. To do this, you need to clearly understand all the pros and cons of both types of security alarm systems.

Wireless alarm

Benefits of wireless signaling

  • Fewer visible elements (the aesthetic aspect, which is important for those cases when, for example, you have just finished renovation, and the phrase “you need to gouge the wall for laying the cable” sounds like a terrible sentence).
  • Ability to quickly change the location of the equipment. This is very convenient if the alarm is installed in a temporarily rented office, apartment, etc. If it is necessary to move, the equipment is simply removed and just as easily mounted in a new place.
  • Possibility of integrated operation of radio channels of various ranges, among themselves and with other systems for transmitting information (GSM-channel, fiber-optic, etc.)
  • Easy to install. No special skills are required to install the alarm equipment yourself. The sensors are connected quickly and easily.
  • Savings on additional fasteners for mounting equipment (as is the case with wired signaling). Plus - savings due to self-installation. You do not have to pay for the services of alarm installation specialists.
  • Independence from power supply. The operation of the wireless sensor is provided by an autonomous power source. Thus, the alarm system will not turn off in the event of a power outage, it will not be subject to fluctuations in the network. Typically, battery life is up to 6 months when combined with an uninterruptible power supply. An indicator signal will signal the impending need to replace the battery. Some systems also provide for sending a message to the owner's number about when to replace the battery.
  • Reliable and efficient way of signal transmission. The means of signal transmission are radio waves, which propagate in different directions and at the most reliable and widespread frequency of the radio channel. Walls, furniture and other objects are not significant obstacles for the radio signal.
  • Additional protective effect due to the miniature design. Agree that the fewer visible alarm details, the lower the chances of an intruder to calculate possible "loopholes" for invisible penetration into the protected area.
  • Possibility of using extraordinary solutions. For example, you can use one GSM alarm system to guard two buildings at once (you just need to install a central unit in one of the rooms and install the necessary sensors). This is possible due to the range of sensors in the area of 100 m. It is really convenient when you need to protect not only the house, but also certain outbuildings.
  • Possibility of expanding the functions of the alarm system. This is achieved by installing additional sensors (smoke, temperature, glass breakage, etc.) after their registration in the central alarm unit.

Disadvantages of Wireless Alarm

  • The need to change batteries and charge the battery. This factor is absolutely not critical, therefore, it is rather a minor inconvenience, and not an obvious disadvantage of the alarm. You just need to pay attention to the indicator signal in time.
  • Some weakening of the radio signal when passing through physical interference. Decreasing the signal range can affect the performance of the alarm system. But this problem can be solved by installing signal amplifiers for wireless sensors. This need should be considered taking into account the specifics of a particular object (material and wall thickness, distance between devices, etc.)
  • Wireless systems are generally more expensive than wired systems. But this is offset by not having to pay for installation and fasteners.
  • Exposure to radio interference. Although it is not high, it can sometimes lead to false positives (from which, in principle, wired systems are not protected either).
  • Dependence on the quality and radius of coverage of the GSM operator's network.
  • Wireless alarms are usually quite difficult to repair.

Wired alarm

Wired alarm is also widely used in modern protection systems for various objects and has its pros and cons.

The advantages of wired signaling.

  • Low cost. In this case, take into account the additional installation costs if the object is complex. But there are also ready-made kits for self-installation.
  • The remoteness of the sensors from the central unit reaches up to 400 m. This is important when installing alarms in houses with two or more floors, as well as in large enterprises or warehouses.
  • Physical obstacles do not interfere with signal transmission. As a result, the signal is more stable and reliable. This is especially true in noisy workshops or in places where power lines are laid nearby.
  • No need to replace batteries. In case of power outages, an additional uninterruptible power supply is used, which can ensure the operation of the system for up to 3-6 months.
  • High degree of maintainability.

Disadvantages of Wired Alarm

  • Possible damage to the cable. Given that a cable is involved in signal transmission, damage to it can reduce transmission reliability.
  • Fairly long recovery. It may take several days for the system to fully recover. For example, a cable is damaged in an unknown place, and a cable is 100 meters long.
  • Dependence on power supply. Broken wires, fluctuations in the supply of electricity can lead to interruptions in the operation of the alarm.
  • Visibility to the attacker. Burglars can deliberately damage the visible elements of the cable or calculate "convenient" ways of penetration.

As you can see, both types of alarms can effectively protect your property. But it is better to install wired alarms at objects that are planned for long-term operation and during repairs (apartment, house, country cottage). A spare cable can be laid in case the alarm functions are expanded in the future. It makes no sense to make an extensive alarm system in the office, which you are going to leave after a month or two.

In the same situations when interference in the structure of the premises is undesirable or impossible (repairs have been made, the house is assembled from ready-made panels, the building is old and will not withstand cable “penetrations”), wireless signaling will be an excellent solution. In addition, it is convenient that it can be installed independently and it will be easier to expand in the future.
