The VM4 showcase detector is now also available in the new housing colours brown and black. This provides an especially discreet security solution for museums, art galleries and bijouteries where the standard white version may not be visually ideal. In darker display cases or with premium exhibits, the new color options allow the detector to integrate harmoniously without compromising security.

Versatile Security Functions in a Compact Device

The VM4 combines multiple detection systems in a compact housing (75 × 28 × 15 mm, IP54):

• Integrated PIR sensor for motion detection

• 3-axis accelerometer as a vibration detector

• Reed contact for opening detection

• Capability to connect up to three external PIR sensors

All sensors can be individually adjusted in sensitivity, allowing the detector to be perfectly adapted to the type of display case, exhibit size, and environmental conditions.

Technical Highlights

• Operating voltage: 9–16 V DC

• Current consumption: < 20 mA (without external sensors)

• Monitoring volume: 0.2–2 m³, depending on conditions

• Alarm relay: ≤16 V, ≤100 mA

• Temperature range: -10 to +55 °C

• Housing colors: White (RAL 9003), Brown (RAL 8016)

• Protection class: IP54

• External PIR sensors: Range 2–5 m, optionally for small movements

Easy Installation and Reliable Operation

Thanks to its compact design and low power consumption, the VM4 is particularly easy to install. The combination of motion sensor, vibration detector, and opening contact ensures reliable alarms in case of unauthorized access to display cases or exhibits. The new brown and black housing options allow for seamless integration in darker exhibition environments without compromising functionality.

The VM4 showcase detector is the ideal security solution for institutions seeking professional, flexible, and aesthetically unobtrusive protection systems. For more information and ordering options, please visit our product page: VM4 Showcase detector
