Ajax Alarm
✅ Faster Installation
Less time on-site, easy device pairing, and app-based configuration.
✅ Professional Remote Management
Installers can check, configure, and maintain installations remotely without always depending on on-site visits.
✅ More Reliable Communication
Models such as the Hub 2 Plus use multiple communication channels: Ethernet, WiFi, and dual LTE SIM cards, providing greater continuity in case of network outages.
✅ Alarm Photo Verification
With compatible MotionCam detectors, Ajax allows visual alarm verification through images, helping reduce uncertainty and false interventions.
✅ Better Experience for the End User
Users can control the alarm from their smartphone, receive notifications, and better understand what is happening in their installation.
✅ More Value for Installers
Ajax allows installers to offer not just an alarm, but a more complete solution: security, remote control, design, automation, and professional maintenance.
Traditional Alarms
❌ Installation Based on Wiring
Traditional alarm systems usually require wiring between the control panel, detectors, sirens, keypads, and other system components.
❌ More Technical Programming
Configuration is typically carried out using a keypad, installer codes, or dedicated software, depending on the model. This requires greater technical expertise and can make setup less intuitive compared to more modern systems.
❌ More On-Site Maintenance
System checks, expansions, or configuration changes often require more physical intervention from the installer. This may involve traveling on-site to inspect wiring, zones, batteries, sirens, or communication modules.
❌ More Limited Expansion
Adding new detectors or devices may require running cables, installing expanders, or modifying zone programming. This can increase installation time, especially in already finished installations.
❌ More Basic Experience for the End User
Users usually interact with the alarm through a keypad, remote control, or basic notifications. While it fulfills its security function, the experience may be less convenient or visual compared to app-managed systems.
