Returning an image from an Alpaca device as a JSON array is very inefficient and can result in delays of 30 or more seconds while client and device process and send the huge JSON string over the network. A new, much faster mechanic called ImageBytes - Alpaca ImageBytes Concepts and Implementation has been developed that sends data as a binary byte stream and can offer a 10 to 20 fold reduction in transfer time. It is strongly recommended that Alpaca Cameras implement the ImageBytes mechanic as well as the JSON mechanic.
