The VOC Industrial Event Camera from Pepperl+Fuchs allows event-driven video recording up to 60 seconds before and after a trigger signal, therefore enabling targeted and simple remote diagnostics as well as automatic documentation.
If a malfunction, a predefined status or process occurs, the trigger initiates the video recording. In an automated parking garage, for example, every parking process should be documented in order to quickly and easily prove the condition of the vehicle in the event of liability. The recording starts every time a new vehicle enters the parking garage. Due to the automatic timestamp and the User Datagram Protocol interface for dynamic text overlays, users can find the files quickly and easily.
VOC Industrial Event Cameras At a Glance
- Event-driven video recordings up to 60 s before and after the trigger signal for simple remote diagnosis or automatic documentation.
- Recording of relevant situations with timestamp and individual additional text for fast analysis
- Easy integration into IT systems via REST API and to standard HMI displays with RTSP
- Flexible use due to large viewing area, high operating temperature range and IP65 degree of protection
- High efficiency: reduced network load through optimized local data storage

Integrated Circular Buffer for Optimized Data Storage
As soon as an event activates the trigger, the camera generates and saves a video recording as a permanent data record. This contains up to 60 seconds before and after the trigger signal. The integrated circular buffer is cyclically filled with the image recording. By recording only relevant situations, the amount of stored data is kept to a minimum. The data is stored on a local, exchangeable SD card with a capacity of 8 GB. Compared to 24-hour video recording, no complex data integration or PC hardware is required here. Depending on the preset resolution, length and quality of the sequence, the event camera can store up to 10,000 events on the card. To further optimize data storage, it is also possible to set video recordings to be automatically deleted at a certain point in time or to overwrite the oldest data with the new data when the memory is full.
Flexibility in Use—Indoors and Outdoors
The electrical trigger signal, e.g. the output of a sensor, is connected to the camera via the digital hardware input. Even more flexibility in use is provided by the high depth of field at 0.5 m to over 10 m mounting distance, the operating temperature range of –30 °C ... +50 °C and the large field of view. At a standard distance of 2.5 m from the monitoring area and an orientation of 0°/180°, the field of view is 3.0 m x 1.7 m. With the same orientation and 10 m distance to the monitoring area, it is 12.1 m x 6.8 m. In addition to the integrated heating against condensation, the aluminum housing and the guarantee of IP65 degree of protection provide optimal conditions for the use of the event camera both indoors and outdoors.
VOC Industrial Event Camera Application Examples
High-Precision Monitoring and Remote Access in Security Applications
The VOC event camera enables reliable monitoring of sensor-secured access areas. If a machine or system is stopped by the access guarding, the recording of the trigger event is available for remote access. Based on the short video sequence, the control room can immediately make decisions on how to proceed.
Reliable Monitoring in Automated High-Bay Warehouses
Automated high-bay warehouses with stacker cranes are designed to create maximum throughput while avoiding breakdowns and downtime—even at the lowest temperatures of –30° C in deep-freeze warehouses. The industrial event camera is mounted directly on the stacker crane and monitors the storage and retrieval processes so that employees can take immediate action in the event of malfunctions.

Reliable Monitoring of Cartoning Machines
With the VOC industrial event camera, possible jams on cartoning machines can be monitored and displayed in real time around the clock. In addition to sensor signals from proximity switches, optical sensors or vibration sensors, the industrial event camera therefore provides visual information that can be collected in a central data acquisition system and used for safety and training purposes. The system automatically makes the data available for analysis—causes are reliably identified and downtimes minimized.
