Onboard video processors

This video processor was developed to give even the smallest camera systems the greatest possible capabilities. The 1500 OEM video processor is a very small, low-power, single-channel, onboard video processing solution with very low power consumption.

The 1750-OEM is a state-of-the-art onboard video processing solution, enhancing small camera systems with advanced capabilities. This compact, single-channel module boasts three digital video inputs, Qualcomm multi-core ARM processing, and multiple output options, making it an ideal choice for seamless integration and top-tier performance in various applications.

This video processor includes two video channels, each of them is offering a full suite of processing functions. This full suite includes full-frame-rate HD IP streaming with KLV data, stabilisation, and object tracking at 1080p/30.

The 4000 OEM is the most powerful of the hardware options. Smaller than the 3000 OEM, it supports full HD and 4K encoding. The 4000-OEM’s multiple digital video inputs include parallel digital compatibility with any 3000-OEM input adapter board, MIPI, and USB-3. Multiple video outputs include ethernet streaming H.264 and H.265, HDMI and HDSDI.
