Charging Head Network’s 3737th disassembly report.
Introduction
The Security Testing Room has purchased a smart camera from the VIRTAVO brand. This camera features a built-in 400W pixel sensor and a dual-lens design, with one lens mounted on a gimbal and the other fixed at a specific angle, effectively functioning as two cameras in one. The dual lenses can simultaneously address security needs in two different directions and support infrared night vision as well as full-color night vision, catering to both home and commercial requirements.
The two lenses of the camera are divided into a gimbal lens and a fixed lens. The gimbal supports 360° monitoring without blind spots and allows for app selection and alarm notifications, as well as two-way voice intercom and one-way video calls. The camera is equipped with a TF card slot, supports loop recording, and is powered via a USB-C interface. Below, we will present the disassembly of the VIRTAVO smart camera, taking a closer look at its internal design and components.

Security Testing Room Disassembly Summary
Finally, here is a list of core components of the VIRTAVO smart indoor camera for your reference.
The VIRTAVO smart indoor camera is equipped with two 4-megapixel lenses, designed with a gimbal + fixed lens configuration. The gimbal lens provides 360° monitoring without blind spots, capable of addressing security needs in two different areas simultaneously. The camera supports three modes: infrared/full-color night vision/off, catering to both home and commercial needs.
The Security Testing Room has learned through disassembly that this camera uses the ALLWINNER V851S main control chip, paired with Wuhan Xinxin memory. The switching buck chip, motor driver chip, and LED driver chip all come from Toread Micro. The gimbal is driven by a stepper motor, connected to the base via a ribbon cable, and the gimbal contains a wireless module for WiFi connectivity. The base houses a microphone and speaker for two-way intercom functionality.
