What category does the digit '7' in the Axis Naming Convention refer to?

In the Axis Naming Convention, the digit '7' specifically identifies products in the category of Encoder/Decoder. This designation is part of a systematic approach used by Axis Communications to categorize their range of products systematically for easy identification and understanding of their functionalities.

Encoders are devices that convert analog video signals into digital format for transmission over IP networks, while decoders perform the reverse action, converting digital streams back into a format suitable for output on standard displays. By using distinct numerical identifiers in their naming convention, Axis helps users quickly ascertain the type and purpose of the product at a glance, thereby simplifying the selection process for their surveillance needs. Understanding this classification is crucial for anyone involved in video surveillance system design, installation, or maintenance, as it directly influences the choice of equipment suited for specific applications.
