Outdoor dome cameras are designed to withstand the harsh elements and are typically more vandal resistant when compared to bullet cameras as they are much harder to move or disable.
As technology has moved to high definition, some of these cameras also support newer formats like HDCVI or HDTVI.
We strongly encourage you to look at the HDCVI section for options to upgrade your recorder while maintaining support for analog cameras, so you can migrate to newer high definition camera models. Those newer sections of our site have a more comprehensive list of cameras.
