CCTV produces its own news broadcasts three times a day and is the country's most powerful and prolific television program producer. Its thirty-minute evening news, Xinwen Lianbo ("CCTV Network News" or "CCTV Tonight", Chinese: 新闻联播), goes on air daily at 7:00 pm Beijing time. All local stations are required to carry CCTV's news broadcast. An internal CCTV survey indicates that nearly 500 million people countrywide regularly watch this program.[23] However, the figure has slumped in recent years; the program now has 10% of the ratings market, compared to 40% before 1998.[24]
The studies included in the meta-analysis used quasi-experimental evaluation designs that involve before-and-after measures of crime in experimental and control areas.[26] However, several researchers have pointed to methodological problems associated with this research literature. First, researchers have argued that the British car park studies included in the meta-analysis cannot accurately control for the fact that CCTV was introduced simultaneously with a range of other security-related measures.[27] Second, some have noted that, in many of the studies, there may be issues with selection bias since the introduction of CCTV was potentially endogenous to previous crime trends.[28] In particular, the estimated effects may be biased if CCTV is introduced in response to crime trends.[29]
Good camera system, picture quality is good only complaint is figuring out which to find the correct app to download. Where were two to choose from, one worked great at home but couldn't view my cameras away from home. Once I downloaded the other app everything was fine. You will need to change your camera picture to HD in the app to receive the best picture. Great system at a great price. I would recommend buying this product...

Currently CCTV has 10 channels broadcasting around the world (CCTV-娱乐 (Entertainment), CCTV-戏曲 (Chinese Opera International), CCTV-13, CCTV-4 in Chinese, CCTV-NEWS and CCTV-9 Documentary) in English, CCTV-Français in French, CCTV-Español in Spanish, CCTV-العربية in Arabic, and CCTV-Русский in Russian. CCTV-4 ASIA used Japanese in Japan. A Portuguese channel is planned for the near future.
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]
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.
Most security cameras simply send you a notification when they detect any type of activity. Others can identify who—or what—is causing the commotion. The Nest Cam IQ and Nest Cam IQ Outdoor offer face-recognition technology, for instance. They automatically zoom in on people who enter the field of view, and send alerts when a face is recognized (they also tell you when an unrecognized face is spotted). These technologies help eliminate needless alerts.
Closed-circuit television (CCTV) is a system of video feeds that are transmitted within a closed system from various security cameras. Unlike broadcast television, video streams are only available to authorized users. Whether you use a one-camera system for your apartment or a four-camera system for your large office, CCTV surveillance cameras are an easy way to upgrade your security system.

CCTV Camera Pros has specialized in surveillance systems with remote viewing capabilities since before the first iPhone was launched. Our co-founder, Mike Haldas, designed one of the first iPhone apps available in the app store to view cameras remotely. Since then, our product research and development team constantly looks for the best iOS apps available. At this time, we are recommending the iDVR-PRO Viewer app that is included with our iDVR-PRO CCTV / HD camera DVRs and HD CCTV systems. You can learn more about how to view your security cameras remotely from iPhone and iPad here.
Vivint offers the perfect balance of all the features you want from a home security monitoring system and a reasonable price. With multiple camera options and professional installation, Vivint gives you peace of mind in knowing that you have the equipment you need to properly monitor your home and that it has been installed correctly. This is the primary advantage of a monitored system in the first place. The one drawback to Vivint is the five-year contract, but as long as you’re happy with the service, that shouldn’t be an issue. The monthly monitoring charge is just under $55 and includes one camera. If you want a professionally installed system with lots of options, Vivint is the system you want.

However, an important feature of some CCTV systems is the ability to take high resolution images of the camera scene, e.g. on a time lapse or motion-detection basis. Images taken with a digital still camera often have higher resolution than those taken with some video cameras. Increasingly, low-cost high-resolution digital still cameras can also be used for CCTV purposes.[citation needed]


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.

Excellent product, great quality images, easy to set up and superb after sales support if needed. I bought the system after my father was scammed by a bogus builder I now feel far more secure that with this system in plain view and recording 27/7 my dads home will not be a target for such criminals again, and the very reasonable cost was a small price to pay for such peace of mind.
(Closed Circuit TV) A self-contained surveillance system comprising cameras, recorders and displays for monitoring activities in a store or company. Earlier analog CCTV systems used VHS tape; either a single VCR for each camera, a "quad VCR" that recorded four low-res images or a time-lapse recorder that handled multiple cameras. Subsequently, specialized digital video recorders (DVRs) with multiple analog inputs superseded VHS tape machines.
Each of these operations is transmitted with a description, allowing detailed monitoring of all actions of the operator. Some systems allow the user to search for a specific event by time of occurrence and text description, and perform statistical evaluation of operator behaviour. This allows the software to predict deviations from the standard workflow and record only anomalous behaviour.[47]

CCTV cameras are a type of security camera that uses an analog video signal (CVBS / Composite Video Baseband Signal) . CCTV Cameras are hard wired to surveillance DVRs via coax cable to record video surveillance footage. CVBS video is standard definition, typically at 480i or 576i resolution. Analog CCTV video information is encoded on one channel and does not include audio.
A recent study done by the observer of Chinese film and television, Ying Zhu, suggests that "CCTV is full of serious-minded creators who regularly experience bouts of self-doubt, philosophical ambivalence, and in some cases, clinical depression." During her extensive interviews with key CCTV players, Zhu notes that "Certain common themes, about ideals distorted or altogether thwarted by commercial and political pressure, emerged." [41] [42]

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.
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.

Indoor security cameras don’t need to be quite as tough as the ones you install outside, but they should be unobtrusive. Many people look for indoor cameras designed to complement their home’s décor. For both types of security cameras, note how they’re powered and consider the proximity of a power source if they don’t run on batteries. The last thing you need is a dead security camera when it matters most.
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.
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 monitoring a front or back door, consider a video doorbell because they can be powered through your doorbell wiring. If you want to monitor another area of your property, you’re better off with a wireless security camera. Keep in mind that while all video doorbells are designed to survive the elements, not all wireless security cameras are weatherproof. So be sure to check the specs of a camera you’re considering if you want to put it outside.

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.

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]

I was a little concerned by some reviews of the camera and the app. Totally unjustified. Excellent in both ways. Set up in about 15 minutes and the quality day and night is very good. Good follow up from the supplier and I am confident they will provide first class support should I require it. I am only average technically but had no problems . Instructions very clear. I would recommend this product.

For the video-quality test, we evaluate the cameras in good light, low light, and zero light (to test night vision) using a unique scene designed by CR engineers to expose weak spots in cameras, whether they’re in the camera’s sensor, lens, or software. These tests assess whether you would be able to see people or objects in the frame, such as a potential intruder. The results of those tests appear in an individual video-quality score for each wireless security camera and video doorbell in our ratings.
Can record straight to a video tape recorder which are able to record analogue signals as pictures. If the analogue signals are recorded to tape, then the tape must run at a very slow speed in order to operate continuously. This is because in order to allow a three-hour tape to run for 24 hours, it must be set to run on a slow time lapse basis, usually about four frames per second. In one second, the camera scene can change dramatically. A person for example can have walked a distance of 1 meter, and therefore if the distance is divided into four parts, i.e. four frames or "snapshots" in time, then each frame invariably looks like a blur, unless the subject keeps relatively still.[1]
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. 

Saving uncompressed digital recordings takes up an enormous amount of hard drive space, and a few hours of uncompressed video could quickly fill up a hard drive. Holiday uncompressed recordings may look fine but one could not run uncompressed quality recordings on a continuous basis. Motion detection is therefore sometimes used as a work around solution to record in uncompressed quality.

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] 

I actually have two of these systems, and intentionally left them off my home network because I wanted to record an event and they performed flawlessly. I could see all 4 cameras on each system using the included monitor and the recordings were saved to the internal hard drive. Only after the event did I reposition the location of the cameras and then plugged the monitor/base station into my home router so that I could check in while away from home. All that was required was finding the IP address of my home router and then typing that into the setup prompts on the monitor/ base station.
No one wants their phone to get overwhelmed with alerts. Shouldn’t your camera know the difference between someone breaking in and a branch moving outside? We solved the "camera-cried-wolf" problem. SimpliCam’s intelligent detection algorithms are calibrated to detect the unique heat signature of humans, so the alerts you get are the ones that matter.

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.

I bought this camera for its price and I just wanted to see the night time picture quality. All my other camera's I have has very poor nighttime vision. So, I was talking to my friend and he told me all cameras have really bad picture quaily. So I installed the camera in as little as 5 minutes. The camera is very well made of steel, not plastic. I placed the camera in the darkest area of my home. Bam!!, I have a fantastic picture at night in real color. This camera you can change the setting to make it show black and white for night vision or color, I chose color The camera is rated at 165 feet night vision, but I can see to the end of my block and that over 700 feet, I can see very clearly into my cars, that I keep on the ... full review
