Interactive Projection Setup
Make a CCTV camera interactive
Read first
Before you start the guide, please review the following pages:
What you'll need
- An analog camera with a BNC (CVBS) output.
- A BNC‑to‑RCA adapter (if your grabber has an RCA input).
- A USB video capture device (grabber), e.g., EasyCAP or a higher‑quality model—make sure it’s compatible with your system.
- An RCA cable (if you don’t have a direct plug‑in adapter).
Step 1 - Select a camera
Contact your local CCTV dealer or use search on CCTV store pages to find the right camera and accessories.
Keep in mind the following (ask your CCTV dealer/consultant):
- Look for cameras that let you manually enable night mode.
- Choose a camera that can be opened so you can access the day/night (light) sensor—this lets you cover it if the camera doesn’t allow forcing night mode—and so you can mount a filter on the lens to block visible light.
- Check which video interfaces the camera provides, or ask the seller for the most convenient way to connect it to a computer. If you choose an analog camera, ask for a USB capture device (grabber) to connect it easily.
- Choose a camera with a field of view slightly larger than the projected area. If you’re unsure, pick a model with adjustable zoom (often via a dedicated knob).
- Choose quality accessories (power supply and cables) to ensure a stable video signal; low‑quality parts degrade overall performance.
Step 2 - Select video grabber (for analog cameras)
Order a few different capture devices (grabbers) and test them to see which delivers the best image quality and lowest latency.
Step 3 - Test the video signal from the camera
- Connect the camera so you can view a live preview on the computer.
- Assess the latency by comparing the monitor view with what is happening in front of the camera.
- Check signal stability—look for blank (black) frames, flicker, or banding. These artifacts can later interfere with interaction in apps.
- Also test the camera with third‑party software to confirm you have unrestricted access to the video stream (more information).
Step 4 - Adjust the camera to work with the projection system
See how to prepare a sample camera for use in a projection system.
