There is a cost in the retention of the images produced by CCTV systems. The amount and quality of data stored on storage media is subject to compression ratios, images stored per second, image size and is effected by the retention period of the videos or images.[113] DVRs store images in a variety of proprietary file formats. Recordings may be retained for a preset amount of time and then automatically archived, overwritten or deleted, the period being determined by the organisation that generated them.

A 2007 report by the UK Information Commissioner's Office, highlighted the need for the public to be made more aware of the growing use of surveillance and the potential impact on civil liberties.[101][102] In the same year, a campaign group claimed the majority of CCTV cameras in the UK are operated illegally or are in breach of privacy guidelines.[103] In response, the Information Commissioner's Office rebutted the claim and added that any reported abuses of the Data Protection Act are swiftly investigated.[103] Even if there are some concerns arising from the use of CCTV such as involving privacy,[104] more commercial establishments are still installing CCTV systems in the UK.

During the coalition's military intervention in Libya in 2011, reports from CCTV tended to support Gaddafi's arguments, claiming that the coalition forces attacked Libya civilians and the military intervention was no different from an invasion. In some of the news reports, CCTV used pictures of protesters demonstration and said that these people were against the coalition's military intervention. CCTV also mislabeled a person holding a banner which said "Vive la France" ("long live France" in French) and claimed that he was a supporter of Gaddafi. Later on 27 March, a Chinese banner that said "Muammar Gaddafi is a lier. [sic]" was shown up in some Libyan demonstration videos from Internet.[55]
Modern digital still cameras can take 500 kb snapshots in the space of 1 second, and these snapshots are then automatically downloaded by the camera software straight to the computer for storage as timed and dated JPEG files. The images themselves don't need to stay on the computer for long. If the computer is connected to the Internet, then the images can automatically be uploaded to any other computer anywhere in the world, as and when the pictures are taken.
One advantage of ordering a monitored system is that you don’t need to worry about the details of each specific camera because you can talk with the home security company’s representative for help picking the system with the appropriate cameras to accommodate your needs. Each company’s cameras will have the functionality to work best with its system, eliminating guesswork. Below you will find the home security monitoring services with the best camera and functionality combinations.
There is strong anecdotal evidence that CCTV aids in detection and conviction of offenders; indeed UK police forces routinely seek CCTV recordings after crimes.[32] Moreover, CCTV has played a crucial role in tracing the movements of suspects or victims and is widely regarded by antiterrorist officers as a fundamental tool in tracking terrorist suspects. Large-scale CCTV installations have played a key part of the defences against terrorism since the 1970s. Cameras have also been installed on public transport in the hope of deterring crime,[33][34] and in mobile police surveillance vehicles, often with automatic number plate recognition, and a network of APNI-linked cameras is used to manage London's congestion charging zone.
Although the primary purpose of the installed surveillance system is to maintain safety and comfort, the security images can be utilized to fulfill a variety of purposes.The i-Pro provides management with vital information to improve store layouts and understanding the number of visitors by integrating the Business Intelligent technology with thermal imaging and a people counter.

A video magnifier, or closed-circuit television (CCTV) system, uses a stand-mounted or handheld video camera to project a magnified image onto a video monitor, a television (TV) screen, or a computer monitor. Cameras with zoom lenses provide variable magnification. In most of these systems, magnification level and focus are set after choosing a comfortable and functional working distance between the camera and the material to be viewed. Some systems use an auto-focus camera. Lower cost video magnifiers often use cameras that have a fixed focus and cannot vary magnification or camera-to-target distance. Most cameras also need their own light source.
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.[35] 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.[36] Critics however noted that benefits of non-monetary value cannot be captured in a traditional Cost Effectiveness Analysis and were omitted from their study.[36] A 2008 Report by UK Police Chiefs concluded that only 3% of crimes were solved by CCTV.[37] In London, a Metropolitan Police report showed that in 2008 only one crime was solved per 1000 cameras.[38] In some cases CCTV cameras have become a target of attacks themselves.[39] 

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.
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.

The average cost to have a four-camera surveillance system professionally installed is between $1,400-1,500. The range people pay for the entire system is much broader--between $700-$2,100--and varies according to how many cameras are being installed, the quality of the equipment, and whether it’s necessary to pay for a permit. Also, average costs vary by city. Wired systems cost more to install than wireless.

Network cameras can be used for very cheap surveillance solutions (requiring one network camera, some Ethernet cabling, and one PC), or to replace entire CCTV installations (cameras become network cameras, tape recorders become DVRs, and CCTV monitors become computers with TFT screens and specialised software. Digital video manufacturers claim that turning CCTV installations into digital video installations is inherently better).

There are two main styles of outdoor security cameras — dome or bullet. Both camera styles are fairly obvious to potential intruders, however, it is more difficult to determine which direction a dome-style camera is pointing, which may help deter a potential intruder. Another thing to keep in mind regarding camera style is whether you want to mount it on the ceiling or wall.

In 2011, new CCTV head Zhanfan "was found to have proclaimed in July [or January,[53] both before the CCTV appointment in November] that journalists’ foremost responsibility is to 'be a good mouthpiece'"[54] (当好喉舌工具). Internet posts of the comment blossomed after the appointment, one "juxtapos[ing] CCTV’s ... Xinwen Lianbo (新闻联播) and photos of Chinese crowds waving red flags with black-and-white images from Nazi-era Germany". Comparisons with the Nazi propaganda chief Joseph Goebbels (gepei’er (戈培尔)) also spread. Official media coverage of the Zhanfan's presentation focused on his call to avoid "fake news and false reports (失实报道)" but also incorporated the "mouthpiece" comment.[53]

The amount of free online storage and cost of storage plans can vary drastically by manufacturer. For example, Netgear’s Arlo cameras come with seven days of free cloud storage, which stores the most recent seven days of motion-triggered video clips, and charge $10 per month or $100 per year for 30 days of storage. Ring video doorbells offer no free storage, but Ring charges only $3 per month per camera or $30 per year per camera for 60 days of storage.
Home security cameras are DIY devices, meaning you set up and monitor them yourself, rather than hiring a security company to do the work and the watching. While they can save you from installation and monitoring fees, you forgo a 24/7 response team when you do it yourself. You’ll have to decide whether you’ll feel safer with professional monitoring or self-monitoring through alerts that pop up on your phone.

We are sooo happy with this monitoring system! It is truly "plug & play", and the color and clarity of the pictures is great. I awoke at 4 a. m. to see clear black & white pictures of our yard. (We have many deer & other wild animals pass through, but none that night.) We have since purchased a hard disc drive for the system, and it allowed us to set to record by motion detection. We had a similar product for many years, but it never had the great color & clarity of picture thar this system has. We would not hesitate to recommend this product to anyone.
*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.
When mounting cameras inside your house isn't an option, you may want to explore hidden cameras, which are cameras that are small and discreet, sometimes fitted into everyday objects such as clocks, smoke detectors, and magnets. If you need to document an important meeting in a public place, a personal hidden camera built into a watch or pen may be a good option. Finally, if you simply want to see what your employees are up to when you aren't nearby, a hidden camera connected to a CCTV camera system may be the best choice.
An article published in CCTV Image magazine estimated the number of private and local government operated cameras in the United Kingdom was 1.85 million in 2011. The estimate was based on extrapolating from a comprehensive survey of public and private cameras within the Cheshire Constabulary jurisdiction. This works out as an average of one camera for every 32 people in the UK, although the density of cameras varies greatly from place to place. The Cheshire report also claims that the average person on a typical day would be seen by 70 CCTV cameras.[77]

However, in any situation where standard-definition video cameras are used, the quality is going to be poor because the maximum pixel resolution of the image chips in most of these devices is 320,000 pixels (analogue quality is measured in TV lines but the results are the same); they generally capture horizontal and vertical fields of lines and blend them together to make a single frame; the maximum frame rate is normally 30 frames per second.
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]

CCTV (中央电视台) broadcast its first program on 2 September 1958. Due to increasing demands, it soon launched its second channel in 1963 and third channel in 1969, followed by the first simultaneous satellite broadcasts nationwide in 1972. Starting from 1 May 1973, Peking Television began broadcasting experimentally in color on its second channel every Tuesday, Thursday, and Saturday using the PAL-D system, and fully converted to color broadcasting by 1977. The network changed its name to CCTV on 1 May 1978.[3] 

If you have valuables that you want to protect, it’s often impossible to lock everything away in a safe or keep them with you when you leave the house, so it makes sense to install CCTV or a home camera. A home camera is small and unobtrusive, but it'll help you relax when you’re not at home, safe in the knowledge that if anything should happen, it'll all be caught on film.
