The Nest Hello $199 succeeds by continuously recording video, so you never have the frustrating experience of firing up the app just to see video of someone walking away. Facial recognition lets you know who's at the door by name, and it can also distinguish between people and cars. What's more, you can separate the field of vision into multiple zones, which helps you customize the notifications. Design and InstallationThe Nest Hello video
doorbell is sleek and slim, at 4. 6 x 1. 7 x 1 inches, and has rounded corners. On its face is a round doorbell button lit by a blue ring, with the camera above it. Image credit: NestIts
small size leaves no room for onboard power, which means the Nest Hello requires a wired connection with 16 to 24 volts of power. That power requirement can be an issue for older houses — I previously had to get the transformer on my 1946 built bungalow upgraded to get a Ring Pro doorbell with the same power requirements to work. The Ring Video Doorbell 2 and the August Doorbell Cam Pro run on batteries, which makes them easier to install. In addition, Nest requires you to install a small module called the "chime connector" inside your doorbell's chime box, located inside the home.

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.
