When selecting high-definition capture cards for a monitoring system, specific needs and scenarios will dictate the choice. High-definition capture cards are primarily used to receive and convert video signals from surveillance cameras for display, storage, and processing on computers or display devices. Here are some types of high-definition capture cards that may be used in monitoring systems:
1. USB High-Definition Capture Card
Features: Connects to a computer via a USB interface, offering portability and ease of use. Suitable for laptops, tablets, and other portable devices, allowing users to conduct video capture and recording in different locations.
Applicable Scenarios: Ideal for flexible deployment and mobile monitoring systems, such as temporary monitoring points and mobile surveillance vehicles.
2. PCIe/PCI High-Definition Capture Card
Features: Inserts into the PCI or PCIe slot on a computer's motherboard, connecting through the system bus. Offers high bandwidth and transmission speeds, suitable for applications requiring high-performance video capture and processing.
Applicable Scenarios: Perfect for large-scale monitoring systems, including banks, airports, subways, and other places requiring long-term, high-definition surveillance.
3. HDMI High-Definition Capture Card
Features: Receives HDMI video signals, suitable for applications requiring high-definition video quality and low latency.
Applicable Scenarios: Ideal for monitoring systems using high-definition cameras, TV set-top boxes, game consoles, and other video sources.
4. SDI High-Definition Capture Card
Features: Receives SDI video signals, suitable for applications requiring high-quality, stable video capture.
Applicable Scenarios: Used in broadcasting, television production, professional photography, and other fields requiring monitoring systems.
5. Multi-Channel High-Definition Capture Card
Features: Simultaneously captures multiple video signals, suitable for monitoring systems requiring surveillance of multiple areas or cameras.
Applicable Scenarios: Ideal for large malls, schools, factories, and other places requiring comprehensive surveillance.
