Cameras have also been installed on public transport in the hope of deterring crime. A more open question is whether most CCTV is cost effective. While low quality domestic kits are cheap the professional installation and maintenance of high definition CCTV is expensive. Gill and Spriggs did a Cost effectiveness analysis CEA of CCTV in crime prevention that showed little monetary saving with the installation of CCTV as most of the crimes prevented resulted in little monetary loss. Critics however noted that benefits of non monetary value cannot be captured in a traditional Cost Effectiveness Analysis and were omitted from their study. A 2008 Report by UK Police Chiefs concluded that only 3% of crimes were solved by CCTV.

The mounting plate 800 may include an opening 810 configured to let through one or more electrical wires, such as the power supply line and the ground line that can be electrically coupled to the plurality of wire terminals 720 of the doorbell camera 106. In some implementations, in accordance with the process 850 of mounting the doorbell camera 106, the mounting plate 800 is fixed onto an area of the surface where the power supply line and the ground line are located. The power supply and ground lines come out of the surface, pass through the opening 810, and are connected to the plurality of wire terminals 720 located at the rear exterior surface of the doorbell camera 106. The device housing 702 is then mounted onto the mounting plate 800 via the fasteners 806 and 808 and their respective fasteners 726 and 728 located at the rear exterior surface of the doorbell camera 106. The power supply and ground lines are concealed within the opening 810 of the mounting plate 800 and the first recess 724A of the device housing 702. Under these circumstances, the depth of the first recess 724A is configured such that a cumulative depth that sums the depth of the first recess 724A and a depth of the opening 810 is greater than a height of connections formed between the plurality of wire terminals 720 and the power supply and ground lines.

99 View at AmazonCheck Walmart?Best daytime video quality in our testsExcellent nighttime video qualityExcellent audio qualityOnly has one year warrantyNo smart home compatibilityMust charge prior to setupNo security camera we tested scored perfectly in both low light and bright daylight environments, though the Flir FX certainly produced the best video quality overall. In bright daylight, the camera showed sharp details, providing a clear image of everything in the room. The Flir FX doesn't have the same clarity in ambient daylight, but still produces excellent video. In nighttime video tests, the Flir FX was a close second behind our top performer, Belkin NetCam HD+, though its video clarity weakened beyond 10 feet. Setting up Flir FX is unusual, as it doesn't work until its batteries, one in the camera and one in its base, charge for at least 30 minutes. However, no other security camera in our review has a battery backup. We didn't like that the mobile app makes you hunt for the button to view video, which isn't as convenient as putting it on the main screen when the app opens. The app has custom alerts, though it doesn't let you schedule recording or connect it to a smart home. The Flir FX has both local and cloud storage options. With local storage, you can use a microSD card up 64GB. The Flir FX has a unique feature, called RapidRecap, which edits numerous hours' worth of footage into a short summary.
