Firstly, Prology iReg Micro is built on the Ambarella A7L processor, which in itself is already not bad. To date, this microchip is widely used in top models of recorders - its computational capabilities allow you to process even heavy video on the fly and receive videos with honest Full HD resolution.
Secondly, the matrix. It used the Omni Vision OV4689 - at one time it was developed specifically for action cameras. A feature of this matrix is the unusual structure of the Omni BSI-2 semiconductor layers, which significantly increases the photosensitivity. This allows you to form each frame much faster, the matrix is able to work normally even at a speed of 120 frames per second.
For the registrar, such a shooting speed, of course, is not needed, therefore in Prology iReg Micro the matrix works in an easy mode for it - 30 fps in Full HD resolution and 60 fps in HD resolution. As a result, the image gets rid of noise, the intelligibility of night shooting and the clarity of a dynamic video are drastically improved. This is especially important for a car registrar - after all, a blurry video with poorly readable numbers can, in which case, turn out to be even useless.
And, of course, optics. As you know, without a good lens, even the best matrices and processors will be useless. IReg Micro uses a hybrid optical system with quartz lenses that have an antireflection coating. Such a design has proven itself in the top Prology models and quite logically switched to more affordable models.

The viewing angle of the lens is 160 degrees diagonally - today it is the most wide-angle lens among Prology recorders. For Full HD resolution, this is a pretty daring decision. Often you have to see registrars from other manufacturers, in which the use of wide-angle optics leads to a decrease in picture quality. This is due to imperfect lens alignment and insufficient attention to the post-processing of the video stream.
The developers of Prology were not afraid of these difficulties and, it must be said, achieved very good results. Firstly, the lens and matrix in iReg Micro represent a single, non-separable precision assembly, which is assembled separately in high-precision production, and after that, when assembling the recorder, it is completely mounted in the housing. This approach made it possible to completely exclude dependence on the errors of the final assembly, while, by the way, remaining within a reasonable price range.

Secondly, the computational capabilities of the processor allowed us to get rid of the very unpleasant feature of wide-angle lenses - fisheye distortions. That's why the Prology iReg Micro uses the Ambarella A7L, and not the weaker processor. Special software processing of the video stream on the fly compensates for these distortions. As a result, the video is quite natural for our perception, but, most importantly, it does not lose detail and legibility.
