Redis in-memory storage
Summary
The choices of technology for connecting sensors and devices to your IoT projects are many, but if you're looking for a high-performance storage system or a system that can support binary data, then you should consider taking a look at Redis.
My only comment would be that because Redis is an in-memory data storage system, you should run some up-front calculations on your image storage requirements to ensure that the Redis memory size allocation has been configured correctly.
