One, Technical Principle
The MAKE1 optical anti-tamper technology adopts infrared reflective tamper detection technology. Its core is an integrated digital sensor that includes a pulse infrared light emitter and a wide-bandlight receiver. During device installation, the sensor is obstructed; the infrared light emitted by the transmitter is reflected by the obstruction and received by the receiver. When the received signal reaches a preset threshold, the system determines that the anti-tamper function has been activated. When the device is removed, the sensor is no longer obstructed, and the infrared light cannot be reflected back to the receiver, thus triggering a tamper alarm.
This technology features concealment and interference resistance: the emitted infrared light lies outside the visible spectrum, making it imperceptible to the human eye; additionally, the infrared light carries a unique encoded signal, preventing interference from natural infrared sources of the same wavelength.
Two, Application Scenarios
1. Asset Security
Applicable to devices secured by strong adhesion or magnetic attachment. When the device is adhered or magnetically attached to a surface (such as valuable equipment, vehicles, shelves), enabling the optical anti-tamper function ensures that any detachment due to external force or theft immediately triggers an alert notification.
2. Logistics and Transportation Monitoring
With the sensor mounted externally and the anti-light alarm enabled, this technology can be used for box-opening detection on sealed containers such as luggage, express packages, and shipping containers. Once the sealed space is opened, the sensor detects incoming ambient light and instantly triggers a tamper alarm, enabling secure monitoring throughout transportation.
3. Biometric Wearable Management
- Personnel Wristbands: Used to determine whether a tracking wristband is properly worn or has been removed
- Pet Management: Suitable for collar wear detection in cats and dogs
- Wildlife Research: Neck-ring wear monitoring for birds to ensure continuous and effective deployment of tracking devices
Three, Technical Advantages
Real-time Response Mechanism
The response time from physical removal to system alert is extremely short, achieving real-time protection with "immediate notification upon detachment".
Concealed Protection
Invisible infrared light makes it difficult for malicious actors to detect the presence of the anti-tamper mechanism, enhancing security effectiveness.
Strong Environmental Adaptability
Encoded infrared signals effectively distinguish environmental infrared interference, minimizing false alarms and enabling operation across various indoor and outdoor environments.
Flexible Installation Options
Supports multiple installation methods including placement, adhesive mounting, magnetic attachment, wristband wear, and neckband wear, offering broad application versatility.
Four, Usage Precautions
1. Surface Color Limitations
Optical anti-tamper cannot be used on pure black surfaces. Since pure black objects do not reflect light, they cannot reflect infrared signals to trigger the sensor. This commonly applies to black boxes, black fabrics, and black-furred pets.
Solution: Apply a small patch of light-colored tape at the sensor location on the black surface to enable normal anti-tamper functionality.
2. Wear Fit Adjustment
When wristbands or collars are worn loosely, movement may cause the sensor to move beyond the detection threshold (5–10 mm) from the skin, resulting in false alarms.
Solution: Adjust the wristband or collar size to ensure a snug fit, maintaining the sensor-to-obstruction distance within the effective range.
3. Detection Distance Limitation
The effective detection distance of the sensor is 5–10 mm. During installation, ensure the sensor remains within this range of the obstruction; excessive distance may lead to detection failure or false alarms.
Optical anti-tamper technology provides a reliable physical protective layer for asset protection, logistics security, and biological tracking through precise infrared reflection detection. Proper understanding of its applicable conditions and limitations enables maximum utilization of this technology's protective value.
