Wireless cameras are used in homes and businesses for security purposes. They are replacing wired cameras because of their convenience; they use radio signals to transmit video to a monitor instead of messy wires. With a few simple devices, you can even receive video from a wireless camera on your laptop.

Connect the wireless receiver's video output jack to the video input jack of the video capture card using the composite video cable, which should have identical yellow heads. The jacks will be clearly labelled and usually coated with yellow to indicate video. On some modern video capture cards, there are several types of video inputs available, including S-video and Component video, which offer high-definition. For now, stick with the regular composite video, because wireless high-definition cameras are a rarity and expensive.
Insert the capture card into the laptop's card slot. These are almost always found to the side of the keyboard, near the front. Consult your laptop's owner's manual if you are unsure of the exact location.
Turn on the camera, wireless receiver and laptop. Install the video capture card's software, which should have come with it.
Open the video capture card's software's menu, which should display a blank image.
Tune the wireless receiver until its frequency is in sync with the wireless camera's frequency. You will know you're done when the blank image on the screen is suddenly replaced by the images being captured by your wireless camera.
Tips and warnings
- Some video capture cards may not come with their own software and may require separate video capture software, which can be downloaded either from online merchants or elsewhere on the Internet. However, these often must be paid for; usually only trial versions are available free of charge.
