Battery Powered Wireless Security Camera 1080p CamHipro App

Battery powered security cameras are ideal for small and residential video surveillance applications. They offer completely wire-free installation which in turn greatly reduced the budget. Nowadays many camera manufacturers offer battery powered security cameras without Ethernet port and some cameras even include solar panels. By employing solar panels, the cameras video surveillance system can be maintenance-free.

In this article, we disassemble CamHipro battery powered security camera. The camera resembles the Netgear Arlo, it’s small and can be installed discretely. The camera includes a microUSB port for battery charging, TF card slot for video recording reset button and power on/off button. All these ports are exposed and no rubber pad for waterproof. Therefore it’s not weatherproof, should avoid outdoor installation.

Disconnecting the main board, we can find the front PCB board which mainly offer night vision and human motion detection.

8L151G micro-processor
8L1516G Ultra Low Power MCU

8L1516G MCU, the medium-density STM8L151x4/6 and STM8L152x4/6 devices are members of the STM8L ultra-low-power 8-bit family. The medium-density STM8L15x family operates from 1.8 V to 3.6 V (down to 1.65 V at power down) and is available in the -40 to +85 °C and -40 to +125 °C temperature ranges.
The medium-density STM8L15x ultra-low-power family features the enhanced STM8 CPU core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the advantages of a CISC architecture with improved code density, a 24-bit linear addressing space and an optimized architecture for low power operation

BA6208L ETA1096
BA6208L ETA1096

We can find the camera utilizes ETA1096 chip for power management and battery charging. ETA1096 is an ETA Solutions’ high efficiency, high frequency synchronous Step-Up converter, capable of delivering output current up to 3A at a 5V output from a 3.6V input. With a low Rdson Power MOS and a built-in synchronous rectifier, its efficiency can be as high as 93% at a 5V/2.1A load. This greatly minimizes power dissipation and reduces heat on the IC, making it ideal for applications that require small board space and have stringent temperature constraints, such as power banks and mobile devices.
Next to the ETA1096, it’s UTC BA6208, as its datasheet indicates, it’s designed for driving reversible motor. In this application, it’s used to control the Infra-red LEDs, such as turn night vision on/off, increase and decrease Infra-red power rate.
