Sync-One2 is designed and built in the UK by Jeremy Curtis of Harkwood Services Ltd.

Jeremy, the founder of Harkwood Services Ltd, needed a tool to measure the AV sync during testing of professional AV installations.  Trying to check spaces was time consuming, and even with a keen eye, not totally accurate.  Unable to find an affordable product to do just what he needed, Jeremy decided to develop one in-house.

Jeremy started using an early version of Sync-One2 saving time, and ensuring his clients systems were correctly commissioned.  Using his Sync-One2 raised some questions from curious people wondering what was going on, and asking if they could have one too.  So in late 2013 Jeremy decided to make Sync-One2 available to others.

More features were added at the request of those in the Post Production, film, and TV industry, to create a single product to cater for a broader range of users at an affordable price.

Sync-One2 has since become the reference tool of choice to ensure accurate AV sync, and is used by a number of household names in Post Production, Digital Cinemas, TV networks around the world.

Also available from Harkwood Services is cmdBridge.  This is a tool to reduce the costs of AV system maintenance, espically where the control system source code is unavailable.  cmdBridge is a command protocol translator, and is also able to translate between physical interface types too.
