3. According to the American Civil Liberties Organization, ACLU, the government in this country is an increasing threat to peoples’ privacy from growing surveillance technological advantage which is said by them to be justified in order to ensure national security. Governmental agencies such as the National Security Agency, the Federal Bureau of Investigation, the Department of Homeland Security, and state and local law enforcement agencies are known to intrude upon the private telecommunications of innocent inhabitants, collect a huge amount of data regarding who people call, and create data bases of what they consider suspicious activities, based on the unclear criteria. The ACLU goes on to say that while the collection of this private information by the government is in itself an unacceptable invasion of privacy, how they use the information is even more problematic to the point of abuse. Otherwise harmless data gets placed on a variety of watch lists, with harsh consequences. Innocent individuals are prevented from boarding planes, are unable to obtain certain types of jobs, have their bank accounts frozen and find themselves repeatedly questioned by authorities without knowing why.

Field of ViewIf you choose a camera with a very wide field of view, at least 160 degrees, you can expect to see every part of the room in front of the camera. The widest field of view in our review is the D Link DCS 2630L at 180 degrees. A wide field of view, which the majority of the cameras we reviewed have, is anything larger than 80 degrees, and it works best if you mount the camera high in a corner that overlooks the room. Digital ZoomDigital zoom allows you to select part of the video and enlarge it. While this helps you get a closer look at something, the quality of a digitally enlarged video won't match that of the original. The Samsung SmartCam HD Pro has the highest digital zoom in the review at 10x.

The first hole 908 may be located on or in proximity to the first fastener structure 806. The release tool 912 may have an extended long apical part that fits into the first hole 908. The release tool 912 can be inserted into the first hole 908 to gain an access to the first fastener structure 806 or the second fastener structure 726 that mates with the first fastener structure 806 when the device housing 702 is mechanically fixed onto the mounting plate 800. The first fastener structure 806 and the second fastener structure 726 are unfastened from each other when the release tool 912 is inserted into the first hole 908 and applies an unlocking action e. g. , a press and a twist on them. In some implementations, a microphone aperture 716 is located on a front cover plate 708 of the doorbell camera 106 to allow sound wave to reach a microphone concealed behind the front cover plate 708. A plurality of speaker openings 718 may be located at a bottom rim surface of the device housing 702 of the doorbell camera 106, and configured to broadcast audio messages e. g. , coming from a remote client device to a visitor near the mounting surface. When the doorbell camera 106 is mounted onto the mounting surface, the speaker openings 718 are not visible from a gaze of the visitor as the visitor is approaching or standing near the mounting surface.
