Ajax wireless intruder alarms — the systems Telexico installs across Sheffield and the wider South Yorkshire area — represent a significant advancement over traditional wired alarm systems. Wireless installation eliminates destructive cabling, allows rapid deployment, and means sensors can be repositioned without engineering visits. Each device communicates via an encrypted proprietary protocol, making jamming attacks substantially harder than conventional systems.
