Look for "Real-Time" cards that offer 30 FPS per channel for smooth video. Some budget 16-channel cards might offer a total of 120 FPS, meaning each camera only records at 7.5 FPS, which can look choppy.
When selecting a DVR card, prioritize these technical specifications to ensure compatibility and performance:
Verify the interface (PCI vs. PCIe) and operating system support. Many older DVR cards only work with Windows XP or 7, so check for Windows 10/11 compatibility before purchasing. Card vs. Standalone DVR: Which is Better?
This determines how many cameras can be connected. Common options include 4, 8, or 16-channel cards, though some professional cards can be stacked to support up to 64 cameras.
Buying a CCTV DVR card (Digital Video Recorder card) is an effective way to turn a standard PC into a powerful surveillance hub. Unlike standalone DVR boxes, these PCI or PCIe cards allow you to leverage your existing computer’s processing power and storage for home or office security.
