Motion sensor is a specialized electronic device used to measure and detect movements within the allowed range. This device is trusted and widely used for many security systems in households, businesses, and commercial centers…
Motion sensors help increase the level of monitoring and security, helping to detect and send warning signals when there are strange intrusions into the system. With an affordable price but extremely effective in control and monitoring. It can be said that this is a reliable electronic device and any business should own it.
How much does the motion sensor cost?
How much does it cost to install a motion sensor? This is the question that users are most concerned about. However, there are many types of motion sensors and many different uses, from surveillance cameras to automatic light on/off… Each type has its price segment.
But in general, the average cost of installing a motion sensor is around $500 for the first installation. But this price may vary depending on the type of sensor, sensitivity level, durability, and scanning range of the device.
What types of motion sensors are there?
There are many types of motion sensors on the market today, such as infrared sensors (PIR), microwave sensors, ultrasonic sensors, and dual technology sensors.
- PIR sensor: is a sensor device that detects changes in thermal radiation within the observation range. Commonly used in lighting, alarm, and security systems, they are often sensitive to people or animals moving through the detection area.
- MW – Microwave sensor: This type often uses microwaves to measure signal reflection, and detect movement through the Doppler effect. The device has a wide range, suitable for detecting vehicles and other types of movement from a distance.
- Ultrasonic sensor: is based on high-frequency sound waves to measure the distance between objects, and is flexibly applied in areas where automatic doors are installed.
- Dual technology sensor: this is a combination of two sensor technologies PIR and microwave to minimize the possibility of false alarms, suitable for environments requiring high accuracy and reducing noise alarms.
Where are motion sensors usually placed?
Motion sensors detect movement, are trusted by many people, and are widely used in places such as homes and shopping malls. Some popular places to install motion sensors are:
- Security systems: motion sensors are often installed on walls or ceilings to detect intrusions and set up close monitoring when there are no people.
- Cameras: cameras with built-in motion sensors will be integrated to record only when there is movement, helping to save storage space for the device.
- Door systems: this type of sensor is installed with a magnet to detect unauthorized intrusions and trigger an alarm when the magnetic field is broken.
- Lighting: motion sensors are integrated into lighting systems to automatically turn on/off according to movement. When there are people, the lights will automatically turn on and vice versa, helping to increase utility efficiency and save energy.
What are the advantages and disadvantages of motion sensors?
Advantages
The application of motion sensors in daily life has brought many benefits to users
- Increased security: the device supports and detects unauthorized movements, sending warnings to users or authorities. In addition, combined with security cameras to provide visual evidence, helping to quickly handle intrusion situations.
- Effective monitoring: motion sensors help minimize the storage of unnecessary videos and support easier investigations by only recording when there is movement.
- Energy saving: because the device helps operate many systems based on human presence and movement, it is easy to adjust on/off, saving energy and helping to reduce operating costs.
- Optimize operations: Collect space usage data, automate processes such as opening warehouse doors when detecting forklifts, helping to improve work efficiency.
Disadvantages
In addition to the outstanding advantages, this type of device still has some limitations that users need to pay attention to:
- Limited range: the device will have some blind spots if installed improperly, which can be easily exploited by intruders, so it is necessary to choose the sensor with the right technical specifications to ensure effectiveness.
- False alarm: some factors such as pets, trees, or heat sources near the sensor can trigger unnecessary alarms, causing inconvenience to users.
- Blocked sensor: Objects such as furniture or decorations can block the sensor, creating security holes.
What should you keep in mind when choosing a motion sensor?
To avoid the risks that may occur when using emotional motion devices, you need to keep in mind the following issues to ensure that you choose the most suitable device.
- Detection range: Determine the area to be monitored and ensure that the variation in the range is installed to protect the entire set, especially areas such as doors and windows.
- Responsiveness: Check the sensitivity of the device, the brightness of the time, and the alarm ability of the sensor to ensure that they work properly without causing trouble.
- Supplier and price: You should choose sensors from reputable suppliers with full warranty, and prioritize choosing products that fit your current budget, ensuring a balance between cost and efficiency.
- Power source: If possible, prioritize choosing power sources such as solar, battery, or direct connection networks to choose a convenient solution that fits the existing system.
- Equipment durability: select sensors that ensure good longevity and stable operation over a long period, reducing maintenance and replacement costs.
