Frequently Asked Questions - CAP-2 DataVideo

Why is my CAP-2 not detected by the computer?

Ensure your OS meets requirements (Windows 7 SP1/8.1/10, macOS 10.13+, Ubuntu 14.04+). Also verify the USB 3.0 port supplies at least 900 mA current. Use the Datavideo-supplied USB 3.0 cable.

How do I connect the CAP-2 for live streaming?

Connect an HDMI source (e.g., camera) to the CAP-2 HDMI IN. Then connect the CAP-2 USB 3.0 OUT to a computer USB 3.0 port using the provided cable. Install streaming software like OBS and add the CAP-2 as a video capture device.

Why is there no picture in my streaming software?

Check that the HDMI source is powered on and properly connected. Confirm the CAP-2 is selected as the video capture device in your software. Ensure no other application is using the CAP-2 (it can only be used by one app at a time).

How can I select between HDMI embedded audio and external audio?

Use the AUDIO SWITCH toggle on the front panel. Push left (AUDIO IN) for the external 3.5mm audio source; push right (EMBED) for HDMI embedded audio.

Why is there no audio or very low audio?

First, check the audio source selection switch. Then verify the audio device settings in your OS: set the CAP-2 as the default recording device and ensure the level is set to 100. In OBS, add an Audio Input Capture and select the CAP-2 device.

What are the minimum system requirements?

For PC: Intel Core i5-4440 3.10 GHz + NVIDIA GeForce GTX 660 or higher. For laptop: Intel Core i7-4810MQ + NVIDIA GeForce GTX 870M or higher. 4 GB RAM or more recommended. A USB 3.0 port is required.

Can I use the CAP-2 with USB 2.0?

Yes, but video format will be limited to MJPG (no YUY2). For best performance, use USB 3.0.

How do I update the firmware on the CAP-2?

Download the UVC V1.3 software and latest firmware from Datavideo. Connect the CAP-2 via USB, open UVC, select the correct COM port, and follow the steps in the manual to update the main and capture firmware.

What should I do if the CAP-2 overheats?

Ensure the ventilation slots are not blocked. Do not place the device on soft surfaces like beds or sofas. Keep it away from heat sources. If overheating persists, stop use and contact support.

Is the CAP-2 compatible with Mac and Linux?

Yes. It supports macOS 10.13.5/10.14.6 (or 10.10+) and Linux Ubuntu 20.04 (or 14.04+). For Mac, note that some versions (e.g., A1706 2018) may have no audio output. For Linux, check compatibility with third-party software.
