From 2001—Barbie™ Wireless Video “Camcorder”

Introduced in 2001 at a price of US$ 99.99, the Barbie “Camcorder”, while styled to look like the real thing, was purely a video camera that transmitted colour video and sound to a separate receiver (with a fake antenna) that could be connected to an NTSC television or VCR with a composite video and sound input. “Suitable for ages 6 to 14.”

The camera and receiver box even have switches that select one of two channels, so you could shoot two camera sitcoms using the switch on the receiver to select the live camera.

The image quality was surprisingly good for what is basically a battery powered (6 AA cells!) toy, but analogue transmission on the 2.4 GHz unlicensed utility band has not withstood the test of time, as it is now vulnerable to interference from WiFi and the many other digital gadgets that use that band.

You can still find them on eBay.
