2. Appointment:
- Working in high-mobility daytime and twilight ground-based reconnaissance systems in visible and near-infrared optical ranges - (0.4-0.9) mk;
- identification by the operator of the purpose of aiming and capture on auto-tracking;
- remote transmission of up to 100 m of video images and control of OEM operation modes via Ethernet 1000BASE-T standard;
- maximum frame rate for video images at a resolution of 12 dB with a resolution of 1280x960 pixels up to 50 fps.

3. OEM modes and algorithms:
- compatibility (image rendering and job management) of an OEM sample with Windows 10 through an optional program;
- capture and automatic tracking of the object selected by the operator in the field of view of the OEM, from 8x8 to 128x128 pixels;
- automatic control of the video at the average brightness specified by the operator of the area in the image;
- adaptive zooming of the image selected by the operator;
- centroid auto-tracking algorithm;
- re-capture of the object after its disruption;
