What does the last letter "E" signify in camera specifications?

The last letter "E" in camera specifications typically signifies "Outdoor ready enclosure." This designation indicates that the camera is designed to withstand outdoor conditions, including exposure to various weather elements such as rain, wind, and temperature variations. These cameras are usually constructed with materials and features that enhance durability and longevity when installed outside. They may also contain protective casing or seals that help prevent ingress of moisture and dust, ensuring the camera can operate effectively in a range of environmental situations.

Understanding this designation is crucial for users who require cameras for external surveillance or monitoring applications, as it informs them about the camera's suitability for outdoor deployment. The other specified choices, while they represent valid features in some camera models, do not relate to the standard use of "E" in this context.
