  The Gamma-ray Cherenkov Telescope (GCT) is one of the Small Size Telescopes
(SSTs) proposed for the Cherenkov Telescope Array (CTA) aimed at the 1 TeV to
300 TeV energy range. GCT will be equipped with a Compact High-Energy Camera
(CHEC) containing 2048 pixels of physical size about 6$\times$6~mm$^2$, leading
to a field of view of over 8 degrees. Electronics based on custom TARGET ASICs
and FPGAs sample incoming signals at a gigasample per second and provide a
flexible triggering scheme. Waveforms for every pixel in every event are read
out are on demand without loss at over 600 events per second. A GCT prototype
in Meudon, Paris saw first Cherenkov light from air showers in late 2015, using
the first CHEC prototype, CHEC-M. This contribution presents results from lab
and field tests with CHEC-M and the progress made to a robust camera design for
deployment within CTA.
