Yuan SC330N4 PCIe Analog Video Capture Card with 4 x Composite Inputs, PAL and NTSC

Recording four analog cameras on one PC needs a card that keeps every channel at full frame rate. The SC330N4 is Yuan’s 4-channel PCIe Analog video capture card, with four BNC composite inputs capturing a total of 120 fps at D1. It suits camera recording, monitoring and inspection systems built on existing analog cameras.

Each input accepts NTSC at up to 720 x 480 and 30 fps or PAL at up to 720 x 576 and 25 fps, with smaller sizes down to 320 x 240 or 320 x 288 for lighter recording. Yuan lists RGB24, RGB32, YUY2, YV12 and NV12 capture formats, and on-card cropping, scaling, auto signal detection and deinterlacing. Four RCA inputs capture mono audio at 8 or 16-bit and 8 to 48 kHz.

The card fits a PCIe x1 slot and carries 8 GPIO lines and a watchdog. Yuan lists multi-instance and multi-device support, and DirectShow and V4L2 drivers let vMix, OBS, Zoom, Skype, Teams, Discord, Slack, Cisco Webex and GoToMeeting use each channel, while Yuan’s Windows and Linux SDK covers custom recording software. The SC330N8 doubles the count to eight BNC inputs, and the SC350N4-L captures four composite feeds at up to 960 x 576.

Yuan lists Windows 7, Windows 8, Windows 8.1 and Windows 10, Linux 2.6.14 or higher in 32-bit and 64-bit builds, Linux on ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX, so the card can sit in an x86 PC or feed an ARM or Jetson based system. The board measures 85 x 84.5 mm. Yuan does not state an operating temperature range on its model page, so ask us where the card will run in a sealed cabinet.
