Another early appearance was in 1973 in Times Square in New York City. The NYPD installed it in order to deter crime that was occurring in the area; however, crime rates did not appear to drop much due to the cameras. Nevertheless, during the 1980s video surveillance began to spread across the country specifically targeting public areas. It was seen as a cheaper way to deter crime compared to increasing the size of the police departments. Some businesses as well, especially those that were prone to theft, began to use video surveillance. From the mid 1990s on, police departments across the country installed an increasing number of cameras in various public spaces including housing projects, schools and public parks departments. CCTV later became common in banks and stores to discourage theft, by recording evidence of criminal activity. 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.

On the other hand, unmonitored home security systems will automatically notify you directly when a sensor is triggered. Once you’re notified, you’ll have to determine whether or not it’s a false alarm or if you should call emergency services. DIY home security systems are less expensive because most features and equipment are purchased upfront – such as SimpliSafe’s professional monitoring package is as low as $14. 99/mo. Once you’ve set up your home security system, you may need to add extra security cameras or sensors to monitor blind spots that may be out of range. Some home security companies sell additional equipment at a discounted rate if you’ve purchased their home security system.

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. Installation isn't difficult, but it is another step. Nest includes everything you need to attach the doorbell to your house, even a huge drill bit in case you have to drill into stucco siding. If you don't want to attempt the installation yourself, the company can connect you with a Nest Pro. But if your existing doorbell's power supply is up to snuff, the process isn't terribly complicated. Facial RecognitionUnlike most video doorbells, the Nest Hello has facial recognition technology. Once you teach it the names of frequent visitors, the companion app available for both Android and iOS will start to name them in the push notifications. The Nest Hello gets big points for including a snapshot from the camera with each notification, so you can get a glimpse of what's happening without having to open the app. The snapshots are extra handy when facial recognition is wrong — which didn't happen often, to be fair.
