c. Memory & Storage: ≥4GB RAM + ≥256GB ROM;
d. Equipped with a ≥15.6-inch 1080P HD IPS touch screen;
4. Expansion Interfaces:
a. Interfaces include but are not limited to HDMI, USB 2.0, USB 3.0, POE network port, DC voltage charging port, Type-C debugging port, Reset key, 3.5mm audio monitoring port, and TF card slot;
b. Supports debugging via Type-C port, realizing real-time display of the device's operation interface on a debugging computer;
c. Equipped with no less than 2 6P aviation connectors, which can connect cameras and provide power and network for cameras to avoid repeated wiring of cameras;
5. The rear panel supports standard VESA mounting holes;
6. Network Features:
a. Single Network Port with Multiple IPs: The whole machine has only 1 RJ45 network port, supporting independent IP assignment for multiple cameras and the terminal system respectively, facilitating compatibility with third-party monitoring system calls;
b. Single Network with Single IP: When no docking with third-party systems is required, the terminal's built-in streaming media service can forward camera video streams and support a certain number of concurrent accesses; external systems only need to communicate with the terminal's Wi-Fi network card or wired network card to obtain video streams of multiple cameras respectively; other devices can directly connect to the terminal to communicate with the entire terminal suite; cameras can be configured on unrelated LAN segments to reduce the occupation of internal network IP resources;

Clamp Bracket
1. Adopts dual-arm and modular design, facilitating the expansion of functional components, as well as installation, operation and maintenance;
2. The screen support arm can hover freely and adjust the angle arbitrarily;
3. The rotating arm can be installed with PTZ cameras, bullet cameras, etc., supporting arbitrary angle pulling, hovering and easy one-hand operation;
4. The base is in the form of a desktop clamp, space-saving and easy to use; no complicated operations such as manual wiring or adjusting the stand position are required for each shooting;

Power Supply Module
1. Power Supply Modes: Supports DC power supply and POE power supply;
2. POE Features: The entire system (including terminal and cameras) can operate with only one POE network cable, realizing simultaneous power supply and network access for the entire terminal, effectively reducing wiring;
