A ring-shaped fill light 303 is mounted on the side wall of the acquisition unit housing 1 to eliminate shadows and reflections, suitable for low-light or backlight scenes. An image processor 304 is installed inside the acquisition unit housing 1. The image processor 304 is electrically connected to the high-resolution camera 301 and the solid-state drive 202. It processes the raw images acquired by the high-resolution camera 301, compresses them into a standard format, and stores them inside the solid-state drive 202. In use, the high-resolution camera 301 adjusts its focus by physically moving the lens group of the optical zoom lens 302 to achieve lossless magnification and capture. The light is converted into a digital signal and transmitted to the image processor 304, where it is compressed into a standard format and stored inside the solid-state drive 202.

[0037] Specifically, when this forensic evidence collector is in use: the display 201 is electrically connected to the solid-state drive 202, receiving and displaying the stored evidence data; simultaneously, the data encryption chip encrypts the stored data based on the AES encryption algorithm, and the data backup module 203 automatically backs up the data in the solid-state drive 202 (e.g., ...). Figure 2 and Figure 4 As shown), when collecting evidence, the high-pixel camera 301 adjusts the focal length by physically moving the lens group of the optical zoom lens 302 to achieve lossless magnification and shooting. After converting the light into a digital signal, it is transmitted to the image processor 304 and compressed into a standard format for storage inside the solid-state drive 202 (e.g., ...). Figure 4 and Figure 6 As shown), the capacitive fingerprint sensor 401 is based on the principle of capacitive sensing. It generates a fingerprint image by detecting the capacitance difference between the finger and the sensor surface and stores the fingerprint data inside the solid-state drive 202.
