In mid-2011 on CCTV, reporter Li Wenxue asserted that Da Vinci Furniture of Shanghai was falsely labeling Chinese-made furniture as imported from Italy. At the end of the year, "Shanghai's industry and commerce bureau fined Da Vinci more than $200,000 last week for what it called substandard furniture",[56] though in August, "the Shanghai Administration of Industry and Commerce ... cleared Da Vinci of any wrongdoing on its Italian product labeling". Also, Da Vinci produced a tape and bank records to back its assertion that it had paid 1 million yuan ($150,000), via a public relations broker, to Li to stop any further negative reports by CCTV.[57] Li said the claim is "slander" and CCTV made no comment. Zhang Zhi'an, an associate journalism professor at Sun Yat-sen University in Guangzhou said, "I think CCTV has too much power", contrasting the Da Vinci case with extortion attempts by journalists at smaller media outlets. Liam Bussell, Asia-Pacific strategic marketing manager for Mintel in Shanghai, said in part, "Da Vinci's definitely done something". Also, "[g]iven the corruption in Chinese media and the volume of counterfeit products in the country, Bussell sa[id] it's often hard to find someone in these disputes who's totally clean".[56]
Proponents of CCTV cameras argue that cameras are effective at deterring and solving crime, and that appropriate regulation and legal restrictions on surveillance of public spaces can provide sufficient protections so that an individual's right to privacy can reasonably be weighed against the benefits of surveillance.[91][92][93] However, anti-surveillance activists have held that there is a right to privacy in public areas. Furthermore, while it is true that there may be scenarios wherein a person's right to public privacy can be both reasonably and justifiably compromised, some scholars have argued that such situations are so rare as to not sufficiently warrant the frequent compromising of public privacy rights that occurs in regions with widespread CCTV surveillance. For example, in her book Setting the Watch: Privacy and the Ethics of CCTV Surveillance, Beatrice von Silva-Tarouca Larsen argues that CCTV surveillance is ethically permissible only in "certain restrictively defined situations", such as when a specific location has a "comprehensively documented and significant criminal threat".[94] Her central reasoning is that widespread CCTV surveillance violates citizens' rights to privacy and anonymity within the public sphere by jeopardizing both their liberty and dignity. She concludes that CCTV surveillance should therefore be reserved for specific circumstances in which there are clear and reasonably demonstrated benefits to its implementation and few ethical compromises.
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.
In October 2009, an "Internet Eyes" website was announced which would pay members of the public to view CCTV camera images from their homes and report any crimes they witnessed. The site aimed to add "more eyes" to cameras which might be insufficiently monitored. Civil liberties campaigners criticized the idea as "a distasteful and a worrying development".[41]
Many similarly priced systems include a hard drive, which this system does not. One of the biggest complaints about the ANNKE is that the cameras are made out of plastic, which makes it easy to strip the screws, so make sure you’re careful installing all the components. Customers also report less-than-stellar night vision quality beyond 15 feet. Similar to the JOANN system above, you get about 10 days of recording with four cameras in 1080p at 12fps.
Before you pick the camera or doorbell you want, be sure to check how much free cloud storage it comes with and how much additional storage costs. Most manufacturers opt for cloud storage—where the footage is remotely stored on a server—instead of memory cards because the video files are large. Without cloud storage, if you miss an alert for a potential intruder you’ll have no idea whether someone tried to break in. Many of these cameras also won’t let you download clips to send to authorities unless you pay up.
Initially, the Publicity Department of the Communist Party of China Central Committee issued directive censorship of programs. During reform in the 1990s, the Party adopted new standards for CCTV, "affordability" and "acceptability", loosening the previous government control.[6] Affordability refers to purchasing ability of programs, while acceptability requires that a programme has acceptable content, preventing broadcasts of material that contains inappropriate content or holds against the Communist Party of China.[7]
Closed-circuit television (CCTV) is sometimes simply called video surveillance. CCTV refers to a system of video feeds that are transmitted within a closed system from various security cameras. CCTV is distinct from broadcast television, in that signals are not sent out for just anyone to intercept. Rather, video streams are available only to authorized users. In practical terms, any home security camera surveillance system is technically a CCTV system. Only you, the user, and your authorized agents, are able to access and review feeds from the cameras in the system.
I just finished upgrading all of my stock annke cameras with this model. The key difference with this bullet camera is it has a horizontal adjustment which allows you to tweak the field of view 1000% better than a camera without a horizontal adjustment. No clue why more bullet cameras do not have this very important feature. Also nice metal construction. Had to hold the button down for 5 seconds to the left to get correct mode not in black and white. Had to make the wire hole a little bigger to fit the huge selection device into the wall. Must be a better way to implement that. But it was just a little notch so not a deal breaker. Very good resolution - much better field of view vs the stock annke cameras and much better clarity at night. Hopefully these hold up over the years! Highly recommend.
Some of the lower-quality home security systems come with only basic door and window sensors that customers can easily install themselves. More high-end equipment packages—like the ones Vivint Smart Home provides—come with a touch-screen control panel and the option to add outdoor home security cameras, all of which require professional installation. Learn more about professional installation services.

The range of a wireless surveillance camera, as in the distance it can transmit its signal, is anywhere between 100 and 500 feet, depending whether the signal is transmitting through open space or attempting to transmit between buildings or hills. Adding antennae can increase transmission range. Range of visibility is thing, and depends on the quality of camera. Cameras can have long-range visibility of 1,000 feet or more, although the quality depends on features such as optical zoom lens, night-vision capabilities, high definition PPF (pixels per foot), and long-range WiFi.
In Sweden, the use of CCTV in public spaces is nationally regulated; requiring permits for any operator (incl. Swedish Police Authority) to install CCTV in public spaces. In an opinion poll commissioned by Lund University in August 2017, the general public of Sweden were asked to choose one measure that would ensure their need for privacy when subject to CCTV-operation in public spaces. 43% favored regulation in the form of clear routines for managing, storing and distributing image material generated from surveillance cameras, 39% favored regulation in the form of clear signage informing that camera surveillance in public spaces is present, 2% favored regulation in the form of having permits restricting the use of surveillance cameras during certain times of day/week, 10% favored regulation in the form of having restrictive policies for issuing permits for surveillance cameras in public spaces. 6% were unsure or did not know.[107]
While these new breeds of security camera offer greater convenience than ever before, they’re far from perfect products. Consumer Reports found that none of the models we tested deliver the HD video quality they promise under all situations. And many models charge monthly fees for some of the most important features, such as cloud storage, facial recognition, and monitoring zones (the ability to focus on or, alternatively, ignore motion within a designated area of the camera’s field of view).
Lasers can blind or damage them. However, since most lasers are monochromatic, color filters can reduce the effect of laser pointers. But filters also impair image quality and overall light sensitivity of cameras (see laser safety article for details on issues with filters). Also, complete protection from lasers of any wavelength would require use of completely black filters, rendering the camera useless.

Project SCRAM is a policing effort by the Halton Regional Police Service to register and help consumers understand the complex issues of privacy and safety that confront households when dealing with installations of home security systems. "The SCRAM program enables community members to voluntarily identify and register their residential video surveillance equipment through a simple, secure, confidential, online form.".[83] It has not been extended to commercial businesses. A wide-ranging effort to provide registration and monitoring of home security and systems. "Security camera registration and monitoring is a community-based crime prevention opportunity and investigative tool that enlists the help of residents and can help prevent crime on three levels. Residential video surveillance cameras can deter criminals from entering the area, can prevent crimes from occurring and help solve crimes by providing valuable evidence to the police."[83]

CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.
The simplest way to think about the types of security cameras is to break them down into two groups: indoor cameras and outdoor cameras. While each of these groups have different styles of cameras within them, those differences will become apparent when you compare features, so separating them further isn’t necessary. For instance, none of the cameras we talk about in this guide are dome cameras, not because dome cameras are of lower quality, but because they simply aren’t necessary for most home security camera systems.

All video magnifiers offer the option of viewing black letters on a white background or white letters on a black background. Controls for contrast and brightness are also standard. Many video magnifiers also provide other special on-screen features and controls including underlining or overlining of text. Some systems work jointly with a computer, offering the option of sharing the computer monitor. Color video magnifiers are useful for reading materials in which color is crucial, such as maps and color photographs. A radical departure in design from conventional video magnifiers is the use of head-mounted displays (HMD). They offer portability and new ways of viewing the display. Being able to capture and save an image is also a new function that has recently become available.
After some research decided on purchasing two: [[ASIN:B01K4DRKSM IeGeek Waterproof Home Security Surveillance Outdoor Bullet IP Camera]] Relatively easy to install mechanically and configure, although a knowledge of IP addresses and router functions is desirable. The instructions, both in book form and the pdf are not extensive (and translated into rather strange English!), and there are many unexplained parameters that are tweakable so beware! The cameras come without a micro SD card on which to record their output. [[ASIN:B012VKWQNU SanDisk Ultra 64 GB Imaging microSDXC Class 10 Memory Card and SD Adapter up to 80 Mbps with UHS-I Ratings]] Separately ordered two of these (64Gb) at about £20 each.
