Introduction

Modern surveillance systems are moving beyond passive recording to smart, event-based monitoring — and motion sensors are at the heart of this transformation.

By detecting movement or human presence, these sensors activate cameras, alarms, and recording systems only when needed, saving energy, reducing data load, and ensuring accurate security coverage.

TRUEiSENSE integrates Microwave (5.8GHz Doppler Radar) and PIR (Passive Infrared) sensing technologies to provide precise human detection for intelligent surveillance applications across offices, warehouses, retail, and smart infrastructure.

🔹 How Motion Sensors Work in Surveillance Systems

1️⃣ Detection Phase:

The sensor constantly scans its area using infrared or microwave waves. Any motion — such as human movement, posture shift, or body heat variation — is detected in real time.

2️⃣ Signal Transmission:

Once motion is detected, the sensor sends an electrical output signal (relay or 12V DC) to the connected CCTV, IP camera, or NVR system.

3️⃣ Camera Activation:

The surveillance camera begins recording, capturing images, or streaming live footage the moment the sensor is triggered.

4️⃣ Data Management:

The event footage is stored, timestamped, and categorized as a motion event, eliminating hours of empty recording and optimizing memory.

5️⃣ Automation Link:

The same motion signal can trigger lights, sirens, or alarms, creating a multi-layered security response.

🔹 Technology Inside TRUEiSENSE Motion Sensors

Microwave Technology (5.8GHz Doppler Radar):

Detects motion through frequency shift in electromagnetic waves.

Capable of sensing through glass or thin partitions.

Offers high sensitivity over large areas.

PIR Technology (Passive Infrared):

Detects motion via temperature and infrared radiation changes.

Ideal for indoor environments and localized detection zones.

True Presence Differentiation:

AI-based filtering helps distinguish between human movement and non-human motion (like fans or airflow).

Daylight Harvesting Feature:

Built-in LUX sensor ensures camera triggers only in low-light or nighttime conditions, preventing unnecessary activation.

🔹 Integration Capabilities

TRUEiSENSE Motion Sensors integrate effortlessly with:

CCTV & IP Cameras (via relay or digital trigger input)

DVR/NVR Systems for event-based recording

IoT/BMS Platforms using Modbus, RS485, or MQTT for smart automation

Lighting Control Systems for synchronized camera + light operation

Output Types:

Relay (NO/NC)

TTL or Digital Logic Output

12–24V DC Signal

Response Time: Less than 1 second

Hold Time: Adjustable (10 seconds to 10 minutes)

🔹 Advantages of Using Motion Sensors in Surveillance Systems

✅ Event-Based Recording: Cameras activate only when real motion is detected.

✅ Data Optimization: Reduces unnecessary video storage and bandwidth usage.

✅ Enhanced Security: Ensures immediate recording of suspicious activity.

✅ Low Power Consumption: Energy-efficient surveillance for long-term operation.

✅ Fewer False Alarms: Radar-based detection ignores airflow, vibration, or lighting shifts.

✅ IoT & BMS Ready: Supports smart building integration for remote management.

✅ Multi-Zone Coverage: Single sensor can monitor wide areas in 360° range.

🔹 Applications

Corporate Offices: Detects entry or motion after working hours and activates indoor cameras.

Warehouses: Monitors restricted zones for human activity or vehicle movement.

Retail Stores: Triggers cameras for customer tracking and theft prevention.

Parking Areas: Activates surveillance when vehicles or pedestrians enter.

Hospitals: Enables low-light or night-time monitoring in patient zones.

Residential Complexes: Integrates with smart door cameras and outdoor security lights.
