1. Anatomy of the AJAX sensor

In this section we break down each of the elements that make up the AJ-MOTIONCAM-B, so you can understand how they work together:

• PIR Lens : 24-zone, 6-plane system that detects thermal and motion variations.
• VGA Camera : Captures up to 640 × 480 px, with night mode thanks to infrared lighting.
• Internal antenna : Enables bidirectional communication at 868 MHz (Jeweller) and Wings for sending images.
• Indicator LEDs : Indicate alarm, tamper (anti-opening) and signal status.
• Battery compartment : Two CR123A 3V batteries, with an estimated autonomy of up to 4 years.
• Tamper anti-opening : Device that alerts if someone tries to tamper with the sensor from behind.
• ABS casing : Durable and discreet material, finished in matte black.

2. Main features

This section summarizes at a glance the key points that make the AJ-MOTIONCAM-B a standout option:

• Volumetric PIR photodetector immune to pets up to 20 kg.
• Security level 2, certified for environments with medium risk.
• Bidirectional and wireless, with a range of up to 1,700 m in open space.
• Send up to 5 images per detection in less than a minute.
• Coverage field of 12 m horizontal (88.5°) and vertical (80°) range.
• Adjustable sensitivity in three levels: low, medium and high.
• Compatible with AJAX Hub 2 for integration into automations and notifications.

4. Applications and return on investment (ROI)

• Residential housing
  Easy, wireless installation with visual and photographic alerts. Savings in installation and maintenance compared to wired systems.
• Offices and shops
  Intruder detection in critical areas (warehouses, server rooms). Reduces losses due to theft and lowers insurance premiums by providing video evidence.
• Pet-friendly spaces
  Thanks to its immunity to animals up to 20 kg, it avoids false alarms and optimizes notification management for security personnel.
• Alert automation
  Integrable with other AJAX devices and automation rules (e.g., turn on lights after activation), improving responsiveness and reducing downtime.

5. Certifications and standards

• Grade 2 : Meets safety requirements for medium-risk environments.
• Jeweller & Wings : AJAX's proprietary protocols for high speed and reliability in wireless communications.
• CE Conformity : Ensures electromagnetic compatibility and health.
• Internal AJAX testing : Validation of operation under extreme temperature and signal conditions.

6. How to choose the optimal sensor

• To select the most suitable detector, consider:
• Installation environment : Open spaces or spaces with many walls require a greater range (1,700 m line of sight).
• Pet presence : If you live with animals weighing less than 20 kg, this model avoids false alarms.
• Need for visual evidence : If you require immediate images to validate an intrusion, prioritize the ability to quickly send up to 5 photos.
• Integration and scalability : Check compatibility with your AJAX hub and expansion plans (more detection zones, sirens, controls).
• Maintenance and autonomy : With CR123A batteries and up to 4 years of life, you minimize battery replacement costs.

7. Frequently Asked Questions (FAQs)

• What is the difference between this sensor and a conventional PIR sensor without a camera?
  The AJ-MOTIONCAM-B adds photographic evidence, reducing human error and false alarms by displaying images of what happened.
• How does temperature affect PIR range?
  Extreme temperatures can affect sensitivity, but AJAX tests its sensors from 0°C to 40°C to ensure stable performance.
• Can it be integrated with home automation systems other than AJAX?
  It only works natively with hub and AJAX protocol; for external integrations you would need a bridge or intermediate API.
• What minimum signal level is recommended for a reliable installation?
  At least three bars of signal in the AJAX app to ensure fast data and image transmissions.
