Description

The MD2019 displacement vibration detector is a sophisticated security device designed to detect unauthorized access or tampering attempts through vibration and displacement sensing. This device is suitable for securing sensitive areas in various settings, including warehouses, banks, retail stores, and other environments requiring high security. Below is an overview of the MD2019’s product features, specifications, and recommended applications.

Product Features

  1. Robust Construction: The MD2019 has an aluminum alloy shell with electroplated paint, which provides durability and resistance to physical damage. It also includes an anti-tampering alarm to alert against any attempts to disassemble or sabotage the device.
  2. 3-Axis Gyroscope Accelerometer: Like the MD2020, this device is equipped with a 3-axis gyroscope accelerometer that detects both vibration and tilt with high responsiveness, ensuring quick detection of any disturbances.
  3. Dual Working Modes:
    • User Mode: Allows for simple operation with up to 4 sensitivity levels, adjustable via a DIP switch, making it user-friendly for general security needs.
    • Engineering Mode: Offers more precise control with up to 16 adjustable sensitivity levels, catering to environments where specific calibration is necessary.
  4. Adjustable Alarm Sensitivity and Vibration Detection: Users can set specific thresholds for vibration sensitivity and the number of detected vibration strikes necessary to trigger an alarm, enhancing the customization of security measures.
  5. Comprehensive Tool Monitoring: This detector can identify typical signs of forcible entry attempts using tools such as drilling machines, hot spears, electric tools, and hammers or chisels.
  6. Sensitivity Adjustment Methods: Includes options for both remote adjustment via RS-485 commands and local manual adjustments, providing flexibility in configuring the device according to situational needs.
  7. Temperature Sensor: Features an in-built temperature sensor that triggers an alarm if there is an exceeding limit or a rapid temperature rise (>5 degrees Celsius within 30 seconds), adding an additional layer of environmental monitoring.
  8. Automatic Axis Balance Correction: Ensures consistent performance and accuracy by automatically correcting any misalignments in the device’s sensor axes.
