The combination of CCTV and facial recognition has been tried as a form of mass surveillance, but has been ineffective because of the low discriminating power of facial recognition technology and the very high number of false positives generated. This type of system has been proposed to compare faces at airports and seaports with those of suspected terrorists or other undesirable entrants.[citation needed]

Closed-circuit television (CCTV), also known as video surveillance,[1][2] is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP), or mesh wired or wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, stores, and other areas where security is needed. Though Videotelephony is seldom called 'CCTV' one exception is the use of video in distance education, where it is an important tool.[3][4]

Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera's associated speakers.
Our team of experts compared the most important features people consider to determine the best home security camera. All the cameras on our list offer a mobile app and include live video streaming, digital zoom, and night vision. Every indoor security camera also features motion detection. Here’s a look at how our top security cameras line up on other vital factors.
For the video-quality test, we evaluate the cameras in good light, low light, and zero light (to test night vision) using a unique scene designed by CR engineers to expose weak spots in cameras, whether they’re in the camera’s sensor, lens, or software. These tests assess whether you would be able to see people or objects in the frame, such as a potential intruder. The results of those tests appear in an individual video-quality score for each wireless security camera and video doorbell in our ratings.

China Central Television falls under the supervision of the State Administration of Radio, Film, and Television which is in turn subordinate to the State Council of the People's Republic of China. A Vice Minister of the state council serves as chairman of CCTV. The organisation has relationships with regional television stations run by local governments, which must reserve up to two channels for the national broadcaster.[10]

A system using VCA can recognize changes in the environment and even identify and compare objects in the database using size, speed, and sometimes colour. The camera's actions can be programmed based on what it is "seeing". For example; an alarm can be issued if an object has moved in a certain area, or if a painting is missing from a wall, or if a smoke or fire is detected, or if running people are detected, or if fallen people are detected and if someone has spray painted the lens, as well as video loss, lens cover, defocus and other so called camera tampering events.[citation needed]

If a clear image is important to you, it doesn’t get any better than the Amcrest ProHD. Its 3-megapixel image sensor and processor stream in crisp ultra-high definition that makes it easy to identify details like faces and license plates. This camera also comes with four free hours of cloud storage, which is pretty rare. The ProHD also has one of the highest weatherproof ratings of all the outdoor security cameras we’ve reviewed. One downside is the lack of smart home capability, but if you’re looking for a stand-alone surveillance camera, the ProHD delivers. This camera has an average Amazon rating of four stars, with more than 750 customer reviews.
On 25 July 2009, CCTV launched its Arabic-language international channel, stating that it aims to maintain stronger links with Arabic nations.[31] "Dialogue, China Story, Documentary, and Science & Technology Review" is a program that air on CCTV-A six time a day.[30] The Arabic Channel serves the Middle East, North Africa, and the Asia-Pacific region.[32][33]

VCA analytics can also be used to detect unusual patterns in an environment. The system can be set to detect anomalies in a crowd, for instance a person moving in the opposite direction in airports where passengers are supposed to walk only in one direction out of a plane or in a subway where people are not supposed to exit through the entrances.[109]
In September 1968, Olean, New York was the first city in the United States to install video cameras along its main business street in an effort to fight crime.[22] Another early appearance was in 1973 in Times Square in New York City.[23] 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.[23] Nevertheless, during the 1980s video surveillance began to spread across the country specifically targeting public areas.[15] It was seen as a cheaper way to deter crime compared to increasing the size of the police departments.[23] Some businesses as well, especially those that were prone to theft, began to use video surveillance.[23] 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.[23] 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.[24] A study by Nieto in 2008 found many businesses in the United States had invested heavily in video surveillance technology to protect products and promote safe workplace and consumer environments. A nationwide survey of a wide variety of companies found that 75 percent utilize CCTV surveillance. In private sector CCTV surveillance technology is operated in a wide variety of establishments such as in industry/manufacturing, retailing, financial/insurance/banking, transportation and distribution, utilities/communications, health care, and hotels/motels, parking areas, jewelry shops.

Within the app, Arlo holds your motion detection footage, with the camera sending a push notification that can be adjusted for sound or motion disturbance. Users can also set up geofencing so the Arlo only activates when your smartphone is out of range. Overall set up and user experience were quite easy with the Q, although during initial connections it did struggle to find our Wi-Fi network. Once live, the Arlo was highly effective at picking out unusual movement, although there is some camera delay.

*TVL stands for television lines and is the maximum number of light and dark vertical lines per picture. For example, if the TVL resolution is 800, there are 400 dark vertical lines and 400 white vertical lines over a horizontal picture. The higher the TVL, the better, clearer the picture. 1,000 TVL is roughly equivalent to 720p for digital picture. 

If you’re using CCTV cameras outside, make sure they’re weatherproof and have the recommended IP rating of 66. Wireless cameras are available, but you’ll still have to run a cable to a power source. Position cameras where they can’t be tampered with, but are accessible for maintenance and cleaning. You can buy vandal-proof cameras, but these tend to cost more.
Yes, analog cameras are especially easy to connect directly to a TV because most TVs have an analog RCA video input. If your TV has an analog RCA input, you can use 75 ohm pre-made camera cable or 75 ohm RG59 coax cable and connect your camera directly to the RCA input of the TV. You can find a more detailed article about connecting security cameras to TVs here.

Very good image for the price. Better than camera that cost 4x as much. (See Pics. They say it all.) Also a wider range of view than other 2.8mm cameras. More detail in the image. Handles lighting much better. See at least 100' with the built in LEDs. Works well with aux. lighting as well. Only downside is no way to flip the image. (Old cameras had a menu that the image could be flipped or mirrored, this camera does not have any of that.)
I bought the 4ch 720p HD NVR a little over 3 months ago. I waited to write a review because you really don't know the value of what you got until ample time has passed. Last May while sitting on my back deck enjoying the warm spring morning, movement within my neighbors brush pile shed caught my attention. It was 4 small kittens playing. I quietly sleeked over to get a closer look. Sure enough, they still had blue eyes so they were only a couple weeks old if that. 2 grey ones with black stripes and dots, a mostly black one with splaters of tan, white and orange and an adorable rambunctious blonde one. I watched for a while but knew momma probably would be back soon so not wanting to spook her and have her move them, I went back to my deck. I went inside and ... full review
