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 (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]

You need to buy and install Power Supply as power source. All our HD CCTV security camera systems include "power supply" so you don't need to look any further but since we are comparing two technologoies, if you were to buy our IP Security Camera Systems, they come with PoE compliant NVRs so you can use ethernet cable to power up your IP security cameras. 

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.
In the United States, the Constitution does not explicitly include the right to privacy although the Supreme Court has said several of the amendments to the Constitution implicitly grant this right.[95] Access to video surveillance recordings may require a judge's writ, which is readily available.[96] However, there is little legislation and regulation specific to video surveillance.[97][98]
The earliest video surveillance systems involved constant monitoring because there was no way to record and store information. The development of reel-to-reel media enabled the recording of surveillance footage. These systems required magnetic tapes to be changed manually, which was a time consuming, expensive and unreliable process, with the operator having to manually thread the tape from the tape reel through the recorder onto an empty take-up reel. Due to these shortcomings, video surveillance was not widespread. VCR technology became available in the 1970s, making it easier to record and erase information, and use of video surveillance became more common.[14]
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.

We are more like Home Depot when it comes to security cameras. We have the expertise when you have to make a decision between brands, technologies, products.
I only bought this as I’ve been having complaints about my dogs being noisy. After installing camera and sorting everything out I let run when I went out came back a couple of hours later to find neighbours waiting for me complaining waking up children. After playing it back I found my dogs were sleeping and only reacted with excitement when I walked in. That stopped him complaining for that day!
One thing we’re a bit bummed about is that the bottom of the Q-SEE’s temperature range is only 14°F, which isn’t as low as other CCTV systems in this article. This makes it unusable to a large portion of people who live in climates that experience extremely cold winters. The Q-SEE warranty is two years, as opposed to the one-year standard the rest of the systems we reviewed have. The 1 TB hard drive included can hold about 10 days of 24/7 recording for four cameras. These cameras record in 720p HD resolution at 30fps.
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.
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.
As you can see from our picks, many of the top-rated home security cameras on the market are roughly in the $200 range, and some of them also require an additional fee to store recorded video in the cloud. We break down any extra fees in our reviews, so it's worth taking a look at each to find out which one fits your budget. The good news is that prices are coming down, and you can get a quality model for around $20! Then again, you can't really put a price on peace of mind.
In Wiltshire, UK, 2003, a pilot scheme for what is now known as "Talking CCTV" was put into action; allowing operators of CCTV cameras to order offenders to stop what they were doing, ranging from ordering subjects to pick up their rubbish and put it in a bin to ordering groups of vandals to disperse. In 2005 Ray Mallon, the mayor and former senior police officer of Middlesbrough implemented "Talking CCTV" in his area.[122]
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

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. 

It's worth taking some time to configure the rules (modes) to suit your requirements. E.g. I have geofencing set up so 2 cameras will record but only one sends notifications if I'm inside the zone. When I'm out of the zone all 5 cameras are set to movement detection, but again only 3 will send notifications - to avoid complete overload of alerts on my phone & watch.
Purchased unit in the fall of last 2016. Worked as advertised right out of the box. The smartphone app was not as user friendly as it should have been, figured it out. A month later, once it began to rain, one of the three cameras mounted outside on garage, under eve, and side of roofline to monitor the side of the house had water inside the lens. The other cam mounted unde the eve of the house began to show a snowy picture. Customer service response was quick. I returned the defective cams and they sent out replacements. Unfortunately, the instructions were vague and the replacement cams were a different model from the original two, so the power supply didn't work. They sent out replacement power supply's, but they too didn't work. I sent back the replacement cams and power cords. They sent me new cams and power cords ... full review

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]

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.

Experiments in the UK during the 1970s and 1980s, including outdoor CCTV in Bournemouth in 1985, led to several larger trial programs later that decade. The first use by local government was in King's Lynn, Norfolk, in 1987.[25] These were deemed successful in the government report "CCTV: Looking Out For You", issued by the Home Office in 1994, and paved the way for an increase in the number of CCTV systems installed. Today, systems cover most town and city centres, and many stations, car-parks and estates.

You'll need high-quality images - sufficiently clear for someone to be identified - if CCTV footage is to be used as evidence in court. However, for the best detail, you need a high resolution - this tends to make the camera more expensive, and can take up a lot of storage space. Also make sure the date and time used to ‘tag’ images are set accurately. 
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]
The local Lenoir, North Carolina crime index is 157, compared to the national crime index risk score of 100. Scores are based on demographic and geographic analyses crime over seven years. Every five minutes 3 robberies occur in the United States. On average homes are three times less likely to be broken into when there's a home security system installed. Having a home security system should be seriously considered by home owners living in Lenoir. One in four Lenoir homes may be burglarized in a year's time with an average loss of over $1,700. This could be higher in some parts of North Carolina—home security systems save money and lives.

Nevertheless, multi-megapixel IP-CCTV cameras are coming on the market. Still quite expensive, but they can capture video images at resolutions of 1, 2, 3, 5 and even up to 11 Mpix. Unlike with analogue cameras, details such as number plates are easily readable. At 11 Mpix, forensic quality images are made where each hand on a person can be distinguished. Because of the much higher resolutions available with these types of cameras, they can be set up to cover a wide area where normally several analogue cameras would have been needed.
