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 contrast to stand-mounted cameras, handheld cameras are designed for bringing the camera to the material to be viewed. They can magnify almost anything within reach, including labels on packages of food and medicine. Handheld cameras are often on rollers, which make them easier to move across a flat working surface. Some manufacturers of video magnifiers that use handheld cameras offer a writing stand as an accessory.
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.

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.


Analogue signals can also be converted into a digital signal to enable the recordings to be stored on a PC as digital recordings. In that case the analogue video camera must be plugged directly into a video capture card in the computer, and the card then converts the analogue signal to digital. These cards are relatively cheap, but inevitably the resulting digital signals are compressed 5:1 (MPEG compression) in order for the video recordings to be saved on a continuous basis.
There are a wide variety of CCTV cameras available, with designs using variations in shape, size, or camera type to achieve a particular goal. Some security cameras come in dome shapes, while others use the more standard rectangular shape that is widely recognized. One important factor to consider is whether the security camera uses visible light or infrared to capture images, as the two are used in drastically different scenarios. IR designs are great for keeping a location secure at night, or in low-light conditions, because they don't use visible light to create an image, they use the infrared radiation given off by a person's body to detect and build an image of their surroundings. Some CCTV systems use what are called IP cameras, which can broadcast their feeds over the internet, making it possible to see what's going on from all over the world.
75 ohm coax cable is used to wire CCTV cameras to DVRs and monitors. Typically a "Siamese type" cable is used which consists of the coaxial cable for video and a pair of stranded cable for power. This makes it convenient for installers to run both power and video using a single cable. Pre-made Siamese coax cable and spools of RG59 coax cable are available for CCTV camera installations. These same cables can also be used for HD-over-Coax cameras such as AHD or HD-TVI cameras.
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.

CCTV cameras are available in different body styles / housing types including bullet, dome, and hidden camera housings. These body styles do not impact the resolution of video that they are able to capture. They are just body style options that are available to fit into different types of installations. For example, a retail store may prefer a white dome to match their ceiling tiles. A night club with dark walls may prefer a black bullet style camera. If both camera types have the same image sensor and 3.6mm lens, they will capture the same resolution and angle of video.
One of the first decisions that you'll need to make is if you need a wireless or wired security camera system, and the correct answer likely depends on where you intend to place the cameras and components. If you have the luxury of being able to drill holes and run wires, you'll appreciate not having to deal with batteries, and may want to look at a wired system. On the other hand, if running wires isn't realistic, you'll enjoy the versatility that Wi-Fi and wireless cameras offer. All these considerations will affect what system you ultimately choose. For example, if you need to capture high-definition surveillance video over long periods, bandwidth is a consideration.
In South Africa due to the high crime rate CCTV surveillance is widely prevalent but the country has been slow to implement the latest technology e.g. the first IP camera was released in 1996 by Axis Communications but IP cameras didn't arrive in South Africa till 2008.[84] In order to regulate the number of suppliers in 2001 the Private Security Industry Regulation Act was passed requiring all security companies to be registered with the Private Security Industry Regulatory Authority (PSIRA).[85]

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]
The fire had implications for the credibility of CCTV, which was already unpopular because of its dominance in the media.[60] The incident was mocked by netizens who reproduced photoshopped photos of the fire and criticised CCTV for censoring coverage. Pictures of the fire are widely distributed on the internet, as a result of citizen journalism.[61]
Criminals may use surveillance cameras to monitor the public. For example, a hidden camera at an ATM can capture people's PINs as they are entered, without their knowledge. The devices are small enough not to be noticed, and are placed where they can monitor the keypad of the machine as people enter their PINs. Images may be transmitted wirelessly to the criminal. Even lawful surveillance cameras sometimes have their data go into the hands of people who have no legal right to receive it.[51]
Similar to the ANNKE system, the Swann lets you skim back through footage to find incidents that happened throughout the day. The camera allows up to 1080p resolution at 30fps. At default settings, you can get three days of recording, but if you lower the settings you can get more than 15 days of recording on a 500 GB hard drive with eight cameras.
Many civil liberties campaign groups, academics and consultants have published research papers into CCTV systems. Opponents of CCTV point out the loss of privacy of people under surveillance, and the negative impact of surveillance on civil liberties. Furthermore, they argue that CCTV displaces crime, rather than reducing it. Critics often dub CCTV as "Big Brother surveillance", a reference to George Orwell's novel Nineteen Eighty-Four, which featured a two-way telescreen in every home through which The Party would monitor the populace.

All these features factor into our unique Smart IQ score for smart home devices, allowing you to see which cameras are smarter than the competition.


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] 

Many sporting events in the United States use CCTV inside the venue for fans to see the action while they are away from their seats. The cameras send the feed to a central control center where a producer selects feeds to send to the television monitors that fans can view. CCTV monitors for viewing the event by attendees are often placed in lounges, hallways, and restrooms. This use of CCTV is not used for surveillance purposes.

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]
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.
