Surveillance of the public using CCTV is common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance, often used in law enforcement, with cameras located on a police officer's chest or head.[5] Video surveillance has generated significant debate about balancing its use with individuals' right to privacy even when in public.[6][7]

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.
*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.

Nest's Cam IQ is the most advanced way to make your home safe, but of course that comes at a price. For £299 per camera it is one of the most expensive in-house Wi-Fi home security camera systems, but it is seamless with the Nest app and can distinguish between people, animals and strangers. It includes a speaker to communicate like using a web cam through the nest app. Its most advanced feature is its facial recognition, which is far beyond what the other cameras we tested could manage.

Recording versus real-time monitoring - Some cameras are designed to be used as after-the-fact evidence, and as such they record everything they see and back it up onto a data storage system of some kind. Others are intended for more real-time purposes and should be used alongside a security team that is watching the cameras for any illicit activities. Some models of camera are capable of doing both of these things, they can record everything they see to a disk or the cloud, while at the same time being monitored from a security station where they can be remotely operated to keep an eye on an ever-changing scene.
The home security market offers many plug-and-play equipment packages that center around an audible alarm to deter intruders who trigger a door or window sensor. They do not offer professional monitoring, so there’s no monthly service contract involved. Monitored home security systems cost between $20 and $60 per month. Although criminology research suggests most intruders flee at the first sound of an alarm, complete home security offers much more than just crime prevention. Protection from house fire or water damage, and assistance with medical emergencies should also be considered. In addition to providing more comprehensive protection, complete home security systems backed by professional monitoring services may also qualify customers for discounted homeowner’s insurance premiums.

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.

Surveillance systems are an essential part of securing your home or business. These systems can range from wireless home security cameras to sophisticated alarm systems that notify law enforcement at the first sign of trouble. The presence of security cameras can serve as a deterrent to would-be thieves, while hidden cameras can protect discretely.

These unobtrusive security cameras connect to your home network and send alerts and videos to your smartphone. Some models need to be plugged into an outlet, and others run on rechargeable-battery power, making them truly wireless. Cameras with a memory-card slot can store video clips locally, on a memory card, but most don’t have that feature, forcing you to store them in the cloud—and allowing manufacturers to charge you a recurring fee.
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]
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]
In 2012, the UK government enacted the Protection of Freedoms Act which includes several provisions related to controlling and restricting the collection, storage, retention, and use of information about individuals. Under this Act, the Home Office published a code of practice in 2013 for the use of surveillance cameras by government and local authorities. The aim of the code is to help ensure their use is "characterised as surveillance by consent, and such consent on the part of the community must be informed consent and not assumed by a system operator. Surveillance by consent should be regarded as analogous to policing by consent."[105]
There are a variety of lens sizes available for CCTV cameras. Generally, the smaller the size of the lens in millimeters(mm), the wider angle of view it provides. For example, a 2.8mm lens provides an angle of view slightly wider than 90 degrees. a 3.6mm lens is slightly less than 90 degrees. You can access a more detailed article to compare security camera lens sizes here.

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.

Swann rounds out our top five for best CCTV systems. Swann is a popular DIY security company with a good reputation, but this system has a few too many mixed reviews to earn it a higher spot in our rankings. It’s the least expensive CCTV system we reviewed, but some customers say installation is easy, while others have difficulties. Others have good customer support and some have poor experiences. However, Swann is a highly regarded company, so if you’re looking for a low-cost CCTV system, this isn’t a bad choice.
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]
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.
While the Nest Cam is one of the more expensive stand-alone security cameras for home use, it makes our list for high resolution and its seamless integration with the rest of the Nest home automation suite. It has two-way talk capability and an incredible 8x digital zoom. The Nest Cam doesn’t have any pan or tilt capabilities, but with its enormous 130° field of view, the motion isn’t as necessary. Although the Nest Cam costs nearly $200, you can find discounts for ordering multiple units at once. Its average rating on Amazon is 4.2 stars with over 6,000 ratings.
This ANNKE CCTV system is one of the most popular on the market. A low price point and overwhelming positive reviews helped the ANNKE make our top five. The ANNKE’s video timeline shows where moments of motion occurred so you can easily skim back and see the video activity for the day, which is a big plus for this system. The ANNKE also has the same motion-detection zone feature as the Amcrest. However, you get what you pay for, and with a lower price point, this system won’t give you all the extra features some other CCTV systems have.

The system is used by Chicago's Office of Emergency Management in case of an emergency call: it detects the caller's location and instantly displays the real-time video feed of the nearest security camera to the operator, not requiring any user intervention. While the system is far too vast to allow complete real-time monitoring, it stores the video data for later usage in order to provide possible evidence in criminal cases.[119]

The Cheshire figure is regarded as more dependable than a previous study by Michael McCahill and Clive Norris of UrbanEye published in 2002.[77][78] Based on a small sample in Putney High Street, McCahill and Norris extrapolated the number of surveillance cameras in Greater London to be around 500,000 and the total number of cameras in the UK to be around 4,200,000. According to their estimate the UK has one camera for every 14 people. Although it has been acknowledged for several years that the methodology behind this figure is flawed,[79] it has been widely quoted. Furthermore, the figure of 500,000 for Greater London is often confused with the figure for the police and local government operated cameras in the City of London, which was about 650 in 2011.[75]
For a seriously adaptable weatherproof option, Netgear's tiny Arlo Pro home security set up gives you multiple cameras from the get go to build out your home security offering. These weatherproof cameras are completely wire-free, meaning you can set them up anywhere while they survive with months of battery life. The standard initial set comes with one camera and a router box, which is not cheap at around £299. This can be quickly upgraded with additional Arlo Pro cameras which add to the price.

On 9 February 2009, the Beijing Television Cultural Center caught fire on the last day of the festivities of Chinese New Year, killing one firefighter.[58] The blaze rendered the 42-story structure unusable, as the zinc and titanium alloy of the outer skin was burnt.[59] The Mandarin Oriental Hotel was destroyed before its expected 2009 opening.[58]
We were surprised to find that this JOOAN CCTV system was so highly recommended. The company website is not the easiest to navigate, and we had difficulty finding some of the technical specifications. Still, customers are overwhelmingly pleased with the performance of this system for the price they pay, which is why it’s in our top five. Although it’s the most expensive CCTV system in this article, it has excellent night vision and receives rave reviews for customer support.
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.
