I. Requirements Analysis:

Solar-Powered Voice Monitoring Pole (PTZ Camera Model) is designed to enable remote video surveillance and warning alerts within designated areas without requiring electricity or network connectivity. Solar energy provides a stable supply of clean power, ensuring energy efficiency and environmental sustainability. The built-in battery stores and delivers power as needed. An independently developed control board integrates high-capacity storage and a 4G wireless network module. Microwave sensors intelligently detect moving objects, triggering voice alerts, warning lights, and video surveillance functions. This system seamlessly integrates monitoring, public announcements, and security alerts into a single intelligent solution.

II. Features:

1. Warning: Public awareness and cautionary function; triggers audio alerts when movement is detected within the microwave sensor range, such as: "Deep water danger, no fishing allowed. Protecting the environment is everyone's responsibility."

2. Publicity: Dedicated custom MP3 playback module triggers targeted voice alerts for promotional announcements; voice recordings can be replaced.

3. Real-time: Promptly and effectively disseminate information and warnings to individuals entering or exiting the designated area; simultaneously trigger camera recording, with image data stored locally on the camera.

4. Economy: Powered by solar energy, it operates or remains on standby for over seven days during cloudy or rainy weather. Equipped with a high-capacity 12V lithium battery, it supports repeated charging and discharging cycles with a long service life, ensuring reliable performance in high-temperature and extreme cold conditions.

5. Intelligent: The solar controller operates in MPPT (Maximum Power Point Tracking) mode, featuring digital technology design and fully automatic operation; equipped with multiple electronic protection functions.

6. Connectivity: Supports wired Ethernet cables and 4G wireless remote transmission; supports mobile phone Bluetooth connection for playing voice messages from your phone.

7. Surveillance: PTZ cameras supporting pan/tilt/zoom functionality; remote control of horizontal and vertical rotation; image capture; remote video playback.

8. Management: Remote control via computer/mobile app; close-range support for one-touch remote control including volume adjustment, previous/next track, Bluetooth direct connection, and power on/off. Supports viewing or downloading/saving via cloud server and mobile app.
