Ajax Hub 2 (4G) Black Wireless Alarm Control Panel with Photo Verification

Ajax Hub 2 (4G) Black Wireless Alarm Control Panel

The Ajax Hub 2 (4G) is the central brain of an Ajax wireless security system, coordinating every connected detector, camera, and accessory while keeping users and monitoring stations informed in real time. Built around Ajax's proprietary Jeweller radio protocol, this black control panel adds 2G/3G/4G (LTE) dual-SIM cellular connectivity alongside Ethernet, giving installers multiple redundant communication paths. It is best known for its alarm photo verification feature, which lets the hub send image sequences captured by MotionCam and MotionCam Outdoor detectors so users and security companies can visually confirm an intrusion before responding.

Key Features

• Triple communication channels: Ethernet plus two SIM card slots supporting 2G/3G/4G (LTE) networks for reliable, redundant connectivity to the Ajax Cloud.
• Photo verification of alarms: Receives and forwards image sequences from compatible MotionCam detectors so users can assess a real threat instantly.
• Large system capacity: Supports up to 32 work scenarios, 9 security groups, 100 connected devices, 5 Ajax ReX signal repeaters, 25 video cameras, 50 protected rooms, and 50 system users.
• Automatic failover: Switches to cellular internet if the Ethernet connection drops, and moves to the backup SIM if one carrier loses coverage.
• Low-bandwidth resilience: Can still transmit photo confirmations even when the connection speed drops to only 0.5 Kbps over a 2G network.
• Backup power: Internal Li-Ion battery keeps the system operational during mains power outages.
• Secure architecture: Receives sensor data in encrypted form and runs on the Malevich operating system with built-in protection against viruses and cyberattacks.
• Tamper and health monitoring: Continuously checks each detector's health every 12-300 seconds via two-way communication, with an individually configurable check frequency.
• Compact, discreet design: Housed in black or white plastic that blends into most interiors.

Ideal Applications

The Hub 2 (4G) suits homes, apartments, retail premises, and small-to-medium commercial sites that need a dependable wireless alarm system with visual alarm confirmation. Its dual-SIM 4G capability makes it particularly valuable for locations without stable fixed-line internet, remote sites needing cellular backup, and any installation where an extra layer of connectivity redundancy is required for continuous monitoring.
