Motion PIR Sensor Price in Bangladesh: The Ultimate Security Guide by Nabiha Infotech

In the modern security landscape of Bangladesh, the Motion PIR (Passive Infrared) Sensor has emerged as the most critical component for safeguarding homes, offices, and industrial warehouses. At Nabiha Infotech, we provide high-performance PIR sensors that act as the "eyes" of your security system, ensuring that no unauthorized movement goes undetected. Whether you are looking for a simple standalone sensor or an advanced pet-immune wireless detector, this guide covers everything you need to know about technology, application, and the latest Motion PIR Sensor price in Bangladesh.

What is a PIR Motion Sensor?

A Passive Infrared (PIR) Sensor is an electronic device that measures infrared (IR) light radiating from objects in its field of view. Unlike active sensors that emit energy, PIR sensors are "passive"—they simply detect the heat signatures emitted by living beings.

When a person moves across the detection zone, the sensor detects a rapid change in infrared energy and triggers an alarm. At Nabiha Infotech, we specialize in Verbex and Kerui PIR sensors, which are engineered to minimize false alarms caused by sunlight or air conditioners.

Why Every Property Needs PIR Motion Sensors

1. 24/7 Unattended Monitoring

Unlike CCTV cameras, which require someone to watch the footage or a high-bandwidth connection for AI detection, a PIR sensor is always "on guard." It works perfectly in total darkness, detecting intruders by their body heat rather than visual light.

2. Cost-Effective Deterrence

Adding a motion sensor to your balcony or entrance is one of the most affordable ways to upgrade your security. When integrated with a loud siren, it provides immediate deterrence, often scaring away burglars before they can even enter your premises.

3. Energy Efficiency

Many of our PIR sensors are used for Smart Home Automation. They can be configured to turn on lights when someone enters a room and turn them off when the room is empty, significantly reducing electricity bills in offices and washrooms.

Types of PIR Sensors Available at Nabiha Infotech

We offer a wide range of sensors to suit different environmental conditions and security requirements:

A. Wireless PIR Sensors (433MHz / WiFi)

Perfect for finished homes where you don't want visible wiring.

• Verbex VT-PIR433: A classic 433MHz wireless detector with a 12-meter range.

• Verbex VT-PIR03W: A WiFi-based sensor that connects directly to your router and sends notifications to the Tuya Smart App.

• Price Range: ৳ 1,450 – ৳ 3,000.

B. Pet-Immune PIR Sensors

Standard sensors can be triggered by cats or dogs. Our pet-immune models, like the Verbex VT-CT60M, are designed to ignore moving objects under 25kg.

• Best For: Households with pets.

• Price Range: ৳ 3,000 – ৳ 4,500.

C. Industrial Wired PIR Detectors

For high-security areas like bank vaults or large factories, wired sensors provide the most stable connection. The Verbex VT-EL55 is a professional-grade wired detector used in many corporate offices across Dhaka.

• Price Range: ৳ 3,500 – ৳ 4,500.

D. Standalone PIR Alarms

These are "all-in-one" units that include a built-in siren. The Verbex VT-M120 is a popular choice for small shops and residential doors.

• Price Range: ৳ 800 – ৳ 1,500.

Technical Specifications: What to Look For

When purchasing a PIR sensor, consider these technical parameters:

• Detection Angle: Most of our sensors offer a 110° wide-angle view.

• Detection Distance: High-quality sensors from Nabiha Infotech cover 9 to 12 meters.

• Temperature Compensation: Vital for the hot and humid climate of Bangladesh, this technology prevents the sensor from becoming less sensitive during summer.

• RFI/EMI Immunity: Ensures that mobile signals or electronic devices don't trigger false alarms.

Installation Tips for Maximum Security

1. Avoid Heat Sources: Do not install sensors directly facing air conditioners, heaters, or windows with direct sunlight.

2. Corner Mounting: For the best coverage, mount the sensor in the corner of a room at a height of 2.1 to 2.4 meters.

3. Cross-Path Detection: PIR sensors are most sensitive to someone walking across their field of view rather than walking directly toward them.

4. Regular Testing: Use the "walk test" mode once a month to ensure the sensor's battery is healthy and the range is still optimal.

Frequently Asked Questions (FAQ)

Q: Do these sensors work during load shedding?

A: Yes. Our wireless sensors are battery-powered, and our wired sensors are usually connected to a control panel with its own battery backup.

Q: Can I get mobile alerts without a central alarm panel?

A: Yes! Our WiFi PIR sensors (like the VT-PIR03W) connect directly to your home WiFi and send alerts to your smartphone via the Tuya app.

Q: How long does the battery last in a wireless sensor?

A: Depending on the traffic in the room, a standard battery lasts between 6 to 12 months. The system will send a "low battery" alert to your phone or panel when it's time for a change.
