The Video device reviewed, is a copy of the well established MD80, and is known as a D001, it was purchased via e-bay for the princely sum of £9.99, and I think you'll agree is a terriffic little device.
It is small inconspicuous and light, and produces quite respectable videos in AVI format, that may be played on a PC.
In 1952, the BBC built and trialed equipment known as the Vision Electronic Recording Apparatus,this high speed multi-track machine used a thin steel tape on a 21 inch (53.5 cm) reel travelling at over 200 inches (510 cm) per second.
This soon became obsolete when Ampex started to sell the Ampex VRX-1000, this was originally developed in 1951, and by 1956, had a price tag of $50,000
Over the years there have been many models that have come and gone, such as the U-Matic, The Philips VCR, Video 2000, and finally, Betamax and VHS.
These later systems had great success in the home market, and offered the home user a reasonably priced equipment (sub £400) that facilitated time shift recording. Although the resolution of these devices was not great, with an equivalent resolution of approximately 333 x 480
More recently, we have seen the introduction of DVD, HDD, and Solid state recording devices, that greatly exceed the performance of these early standards with DVD resolution being approximately 852 x 480
As with all electronic equipment, there is a trend to produce smaller and smaller items, this enables such devices to be used for surveilance, or other obscure purposes such as aerial photography. (As John G4XTS demonstrated on his Sky-Eye presentation 10th Mar' 11)
