Unit PoE CAM

SKU:U121

Description

Unit PoE CAM is an open-source programmable network camera with integrated PoE (Power Over Ethernet) functionality. The hardware uses an ESP32 as the control core, combined with a W5500 embedded Ethernet controller and a 2MP image sensor OV2640, along with a high-capacity memory combination of 8MB PSRAM + 16MB Flash.

The camera is compact and supports flexible power options. Simply connecting an Ethernet cable enables stable image transmission, making it ideal for warehouse monitoring, scheduled image capture, and other application scenarios. Features include:

Plug and Play:
- Automatically obtains an IP address when the network cable is connected. Any device within the same local network can access the camera image.
- The factory firmware integrates an image transmission module, which provides not only image data access but also API interfaces for adjusting image parameters (such as white balance, exposure, gain, and resolution).
- Comes with a PC-side CameraTool that also supports UART image transmission.
Feature-Rich:
- Built-in ESP32 with a reserved programming interface, providing support for secondary development.
- The W5500 embedded Ethernet controller supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols.
- Supports multiple image output formats and allows image parameter adjustments.
High Flexibility:
- Supports PoE power supply, integrating power and network into one cable for simplified wiring; also supports 5V power supply.
- Equipped with a GROVE expansion interface.
- Comes with a fixed camera clip that supports both wall mounting and ceiling installation.

Notes:
1. PoECAM requires an external ESP32 Downloader for programming. You can click here to buy the M5 official ESP32-Downloader kit, which includes an adapter board for easier connection.
2. The PoECAM factory firmware automatically obtains an IP address after connecting to a switch and starts a web server. By checking the serial port output of PoECAM, you can get the IP address and image stream URL. By accessing the URL in a browser under the same LAN, you can preview the real-time image.
