The company did not give a numerical score, but instead pointed out whether each camera was category was "vulnerable," "secured" or "partially vulnerable" with regard to each category. Of the IP cameras tested, the Logitech Circle, the Myfox Security Camera and the Netgear Arlo fared the best. Each earned three out of a possible three stars from AV TEST. The company found "no noticeable vulnerabilities in the communication of the camera and app" in each camera, meaning that they're about as secure as IP cameras can get. However, AV TEST noted "optimization potential" for each camera's companion mobile app, suggesting that the user interfaces are not as user friendly as they could be. This is not a trivial issue — the more obtuse a UI, the less likely a user is to take charge of his or her own security, which could lead to vulnerabilities down the road.

An image sensor array 1114 may be disposed on top of an end of the sensor board 1108, and the lens assembly 704 may be further disposed on top of the image sensor array 1114, such that light passing through the lens assembly 704 arrives at the image sensor array 1114 to form an image captured by the image sensor array 1114. In some implementations, the sensor board 1108 includes an image processor. The image processor of the sensor board 1108 is optionally located directly below the image sensor array 1114 to facilitate further processing of the image captured by the image sensor array 1114. In some implementations, the sensor board 1108 also includes a connector for communicatively coupling the sensor board 1108 to the image sensor array 1114. In some implementations, the image sensor array 1114 and/or the image processor of the sensor board 1108 is thermally coupled to a heat spreader 1138 that is disposed under the image sensor array 1114 and configured for dissipating heat generated while images are being captured and processed. The sensor board 1108 may include one or more of a power supply connector 11082, an AC DC converter 11084, a voltage regulator 11086 and a power unit 11088.

Compared to photoelectric smoke detectors, it consumes less power so a small battery can power it for month and is independent of external wiring. Since ionization type smoke detectors can detect particles smaller than smoke particles, they are prone to false alarms. Ionic smoke detectors use a radioactive isotope americium 241, and rules on proper disposal vary in each region. Some European countries have banned ionic smoke detectors. Aspirating smoke detectors ASD These are lesser known compared to ionic and photoelectric smoke detectors. It is best for rapid smoke detection is crucial like in a room filled with combustible chemicals and gases, and even tobacco. Pipe networks can be constructed leading to ASDs that can easily be hidden. This works well in hotels and posh offices where smoke detectors may look aesthetically displeasing. The National Fire Protection Agency recommend that people install combination alarms, that is, a combination of photoelectric and ionization technology. However few alarms combine both kinds of detection. Combination alarms rarely carry a built in carbon dioxide detector.
