Regula 4205D is constructed in a metal body as a standalone unit for desktop use. Control buttons on the front panel are responsible for the activation of light sources and adjustment of camera parameters in different examination modes.

The device has a spacious working area over the object stage, clamps for fixing examined documents, and a mount for fixing the device on a table (G-lock for anti-theft). The monitor angle and its brightness can be adjusted.

Regula 4205D is equipped with modules for reading MRZ, IPI, barcodes and RFID chips. It can be optionally supplied with an integrated information reference system to compare the examined document with the corresponding document template from the database.
