In 1998, 3,000 CCTV systems were in use in New York City. The studies included in the meta analysis used quasi experimental evaluation designs that involve before and after measures of crime in experimental and control areas. However, several researchers have pointed to methodological problems associated with this research literature. First, researchers have argued that the British car park studies included in the meta analysis cannot accurately control for the fact that CCTV was introduced simultaneously with a range of other security related measures. Second, some have noted that, in many of the studies, there may be issues with selection bias since the introduction of CCTV was potentially endogenous to previous crime trends. In particular, the estimated effects may be biased if CCTV is introduced in response to crime trends. It has been argued that problems of selection bias and endogeneity can be addressed by stronger research designs such as randomized controlled trials and natural experiments. A 2017 review published in Journal of Scandinavian Studies in Criminology and Crime Prevention compiles seven studies that use such research designs. The studies included in the review found that CCTV reduced crime by 24 28% in public streets and urban subway stations. It also found that CCTV could decrease unruly behaviour in football stadiums and theft in supermarkets/mass merchant stores. However, there was no evidence of CCTV having desirable effects in parking facilities or suburban subway stations.

Accordingly, they will hesitate prior to struggling executing something. Here are the reasons why I choose CCTV dome cameras: Vandal proof design By the virtue of the dome shape, dome cameras are more vandal proof. First, it is difficult for a vandal to figure out how to approach disabling a camera. Second, before disabling the camera, he would have to deal with the protective dome. So that is a double whammy. As in any crime, time is of essence and the vandal may think twice before attempting to vandalize the camera. More inconspicuous outlook A dome camera can be equipped with a tinted dome, usually of a dark color. That hides the camera inside very well. It makes the dome design the most inconspicuous design. In business, that has an advantage of not unduly disturbing the customers. Less obvious to know what direction the camera is pointing to Because of the tinted dome, it may be quite difficult to ascertain what direction the camera inside is pointing to.

No indication is given with regard to scale but, based on the size of the camera sensors in relation to the overall size of the doorbell, it wouldn't likely be much larger than a few inches wide. Background: Samsung has had at least some experience in the category of camera enabled doorbells and similar technologies thanks in part to former subsidiary Hanwha Techwin and its SmartCam lineup. However, it has been quite some time since any new products were launched under the Samsung branding. Finalization of the sale of Samsung Techwin to Hanwha Group was completed in 2015, with the newly merged company rebranding as Hanwha Techwin. The Korean tech giant's efforts in the space since that split have been almost entirely non existent. Hanwha Techwin has gone on to continue making cameras and still utilizes Samsung's SmartCam and WiseNet branding as well as online services for the storage and subscription services side of the business. That means that signing up for or checking in on a subscription still relies on Samsung SmartCam site. That includes intelligent face recognition and subsequent alert features which aren't at all unlikely to find their way into Samsung's own cameras if it does decide to release some based on the patented design. Impact: There are some key differences between Samsung's previous offerings in the space, those sold under Hanwha's WiseNet branding, and Samsung's newly patented doorbell camera. The biggest of those is the inclusion of two separate camera sensors. Samsung has been including two cameras in several of its big name products over the past few years and their inclusion here isn't surprising.
