Industrial event camera enables event-driven video
Pepperl+Fuchs is expanding its industrial vision portfolio with the VOC Industrial Event Camera.
The VOC Industrial Event Camera from Pepperl+Fuchs allows event-driven video recording up to 60 seconds before and after a trigger signal, enabling targeted and simple remote diagnostics and automatic documentation. If a malfunction, a predefined status or a process occurs, the trigger initiates the video recording. In an automated parking garage, for example, every parking process should be documented to quickly and easily prove the vehicle’s condition 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 easily find the files.
Optimised 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. An 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 optimise data storage, it is also possible to set video recordings to be automatically deleted at a certain point or to overwrite the oldest data with the new data when the memory is full.
Easy Integration with IT systems and standard HMI displays via REST API and RTSP
Camera settings are easily adjusted due to the web-based, password-protected user interface. It displays the camera’s live image in HD quality so that it can be configured remotely – without needing external software. In addition, REST API allows you to program a custom user interface and integrate the camera directly with IT systems. It can also read information and issue commands, such as a trigger signal. The real-time streaming protocol RTSP enables straightforward integration into standard HMI displays.
Flexibility in use
The electrical trigger signal, e.g. the output of a sensor, is connected to the camera via the digital hardware input. The high depth of field at 0.5m to over 10m mounting distance along with a large field of view provides even more flexibility in use in operating temperatures ranging from –30 °C … +50 °C. At a standard distance of 2.5m from the monitoring area and an orientation of 0°/180°, the field of view is 3.0 m x 1.7 m. In the same orientation, at a 10m distance to the monitoring area, the field of view is 12.1m x 6.8m. In addition to the integrated heating against condensation, the aluminium housing and the guarantee of IP65 degree of protection provide optimal conditions for the use of the event camera both indoors and outdoors.
