These devices are quite functional, are Autonomous and can be attached to any mobile items or even clothes. This category of registrars is called wearable because it’s very fast and convenient to move.
Among the leading advantages of high-tech videopreview worth noting:

- convenient to use.
Portable DVRs are designed for fixing information in a complex environment, where possible the use of conventional, stationary video cameras. Tiny technical devices can be easily carry in pocket or bag.
Basic principles of devices
Mini DVRs — this is a specialized equipment, which consists of two separate elements interconnected among themselves, namely:
- directly camera module;
