  The European Southern Observatory’s Very Large Telescope (VLT) provides support for high-performance industrial cameras with its Technical Detector Control System (TDCS). Until now, TDCS has used a communication interface based on an API from Allied Vision Technologies (AVT), which only supports cameras made by AVT. As part of the VLT 2019 release, a new communication interface has been developed for TDCS using Aravis, the open-source library for GenICam cameras. Aravis has been independently developed to provide support for cameras from any vendor, although this is not guaranteed. It reads the GenICam interface of a GigE Vision camera to enable control. It also has capabilities for USB3Vision cameras. With this new communication interface, support for other manufacturers is now possible. It has been tested with cameras from AVT and Basler, and further tests using a CameraLink camera with a GigE Vision adapter are planned. This paper will discuss the capabilities of Aravis, considerations in the design of the communication interface, and lessons learnt from the implementation.
