An image transmission system with privacy protection includes a privacy request processor which receives a request to secure at least one object type in an image prior to transmission of the image to a receiving system. An object detector receives the image data from a camera and processes the image data to identify at least one predetermined object type in the image data. An object scrambler receives a set of protected objects from the privacy request processor and receives the image data with identified objects of the predetermined object type and operates to obscure the image data for any identified objects identified as protected objects prior to encoding and transmission to a remote receiver site.
