How to Build a Wireless Camera Using an Existing Wired Camera


Wireless cameras are quickly becoming the norm, replacing the once standardized wired security camera systems. Wireless cameras, however, are inherently more expensive than wired cameras of similar quality, and you may not wish to spend the money to replace an entire system when you already have a set of wired cameras. Thankfully, there's a fairly easy method of converting your outdated wired camera into a wireless camera.

Things You'll Need

  • Wireless video transmitter
  • Wireless video receiver
  • 2 composite video cables
  • Velcro strips
  • Monitor

Converting Wired to Wireless

  • Plug the yellow end of the video cable into the "Video out" jack of the camera. The jack is typically located at the back of the camera and coated in yellow to match the cable.

  • Plug the other yellow end of the cable into the "Video in" jack on the video transmitter, which should also be yellow.

  • Take the other video cable and connect the "Video out" jack on the wireless video receiver to the "Video in" jack of the monitor. The monitor's video jacks are usually located on the back or side.

  • Turn on all devices and set the monitor to the proper video channel, which will vary depending on the brand. Typically, the video channel is below channel 001 (or 01) and labeled either "AUX," "VIDEO," or "INPUT."

  • Tune the receiver to the transmitter's frequency until the image from the camera appears on the screen.

Tips & Warnings

  • You can record your images remotely by placing a VCR or other recording device, like a DVD recorder, in between the wireless receiver and monitor. Connect the "Video out" jack of the receiver to the recording device's "Video in" jack. Then connect the recording device's "Video out" jack to the monitor's "video in" jack. This setup allows you to simultaneously watch your images and record them.
  • For aesthetic purposes, you may wish to attach the video transmitter to the camera using velcro strips. Simply attach one strip to the transmitter, then another to an open spot on the camera (possibly the top or where there are no buttons) and then attach.
