Security systems, whether for individuals or businesses, can operate on two main principles: wired and wireless. Each has advantages and specific features that influence the choice depending on the type of building, budget, and security needs.
A wired system connects all of its components — cameras, detectors, alarms, or fog generators — to a central unit via physical cables. This architecture ensures a stable connection and continuous data transmission, without relying on radio waves or batteries. It is often favored in new construction or during major renovations, as cable routing requires integration work. Wired systems are distinguished by their reliability and resistance to interference, while requiring little maintenance once installed.
Conversely, a wireless system uses radio links to communicate between the central unit and the various security devices. This type of installation is faster and more flexible, as it does not require cabling. It is particularly well suited to already occupied buildings or environments where work is limited. Wireless equipment runs on batteries, allowing it to be easily moved or added as needs evolve. However, they require regular monitoring of charge levels and may be susceptible to certain electromagnetic interference.
The choice between a wired and a wireless system depends on several criteria: the layout of the premises, technical constraints, the desired level of security, and the possibility of carrying out work. In large professional installations, wired is often preferred for its robustness and stability. Wireless, on the other hand, is attractive for its simplicity, modularity, and adaptability to existing spaces.
In Switzerland, the company Watermelon installs both wired and wireless systems: surveillance cameras, alarms, fog generators, connected access controls, and smoke detectors, taking into account the specific needs of each client and the particularities of the site.
