It’s hard to say who would be the real winner when comparing CMOS and CCD security cameras on sensitivity and noise. However, based on the current technology and the overall performance, the CCD security cameras are the winner in round 3 (perhaps would be a temporary victory).

Security camera CMOS image sensors are able to integrate various types of applications on one versatile chip. CMOS image sensors in security cameras typically require lower bandwidth.

He noted that Russia has been making inroads in Africa for some time, particularly though the Wagner mercenary group, which has gotten involved with governments in Mali, the Central African Republic and other countries.

In addition, travelers passing through Addis Ababa Bole International Airport, one of the continent’s major transport hubs, will be met with large-screen digital video promos for RT.

RT gets hundreds of millions of dollars in funding. In its early years, it managed to attract big names to host its shows, including Wikileaks founder Julian Assange and late American TV host Larry King.

Security camera CCD image sensors, on the other hand, require both internal circuitry and external elements for amplification and conversion into digital signal. That’s the main reason why security cameras with CCD image sensors often suffer from heat issues.

CCD security cameras, on the other hand, use “global shutter”, which means it exposes the entire sensor instantly. Thus CCD security cameras are less susceptible to jello or vibration.

What they don't advertise is that the Russian outlet being promoted has been largely blocked in the West for being part of Putin's propaganda network and for pushing disinformation, including about the war in Ukraine.

QE (Quantum Efficiency) is a measure of how efficiently the security camera CMOS and CCD image sensor converts light (photons) to digital signal (electrons). The more electrons in a pixel during the integration period of a security camera image sensor, the more sensitive the sensor is.

The ad campaign seeks to tap into Africa’s colonial past — another tactic that disinformation experts say Russia regularly uses to try to sow division.

“They all come from the same handful of countries. And yet they have the gall to tell the entire world what to think and how to feel about the rest of the world, even about the ‘audience’ countries themselves,” she wrote.

Silicon Valley giants also reacted. Meta blocked RT Facebook and Instagram pages in the European Union. Microsoft removed RT from its platforms, and Apple removed it from its App Store in all countries but Russia. YouTube blocked RT in March 2022, though its content can reportedly be found on the channel through proxies.

For example, security cameras with CMOS image sensors and optical zoom can offer even much clearer images/videos than CCD image sensors.

Based on the above information concerning CMOS and CCD security camera image sensors, and the detailed comparison of two types of images sensors, you can find that each type of security camera image sensor has its own pros and cons.

CCD IP security cameras have great WDR (wide dynamic range), so security cameras with this type of image sensors perform greatly at low-light conditions.

“Since March 2022, RT headquarters in Moscow has had its eyes fixed on Africa, where it is planning a long-term presence,” Reporters Without Borders said in a statement last year. The organization says RT is “available in the Maghreb, Côte d’Ivoire, Senegal, Burkina Faso and Cameroon.”

CCD stands for charged-coupled device. In a CCD security camera (system), pixels are represented by p-doped metal-oxide-semiconductors capacitors.

CCD image sensors in video surveillance cameras move their charged cells across the chip, so they are less prone to image distortion. Thus CCD image sensors in security cameras tend to have higher spectral sensitivity to light and produce far less noise than CMOS security cameras.

RT is using the narrative that Russia was never a colonial power to try and gain traction in Africa, experts say. Many African ruling parties have strong historical links to Moscow because the former Soviet Union supported their liberation struggles against colonial or white-minority rule.

Anton Harber, a former journalism professor at Johannesburg's University of the Witwatersrand, said he thought RT’s ad campaign was “too dated” to hold much sway with young Africans — using African leaders from generations ago, some of whom are now viewed skeptically.

The Read Noise (RN) is the measure of security camera image sensor noise. The higher the read noise level, the more sensitive the security camera image sensor is.

Security cameras with CCD image sensors are typically considered to offer much higher resolution images, photos or videos.

Though many African countries were loath to take a stance on the Ukraine war, with most abstaining from U.N. votes on the issue, RT wasn’t immune from problems in Africa. South African satellite broadcaster MultiChoice cut RT from its pan-African DSTV service, saying EU sanctions had forced them to do so.

CCD security cameras offered better low-light or night vision performance, especially in higher temperatures a few years ago. Nowadays, CMOS security cameras sometimes even surpass CCD CCTV IP security cameras in sensitivity.

Billboards and videos popping up in several African cities show 20th-century independence leaders and anti-colonial quotes as part of a drive to promote the Kremlin-backed outlet RT.

And it’s unclear what became of plans announced in 2022 to open an English-language hub in Johannesburg. Asked via email by VOA, Belkina said it was operating. The journalist chosen to run the hub, Paula Slier, has since left RT. When VOA reached out via messaging app she said as far as she was aware, there was no brick-and-mortar office in the city now. But she did not comment further.

CCD security cameras typically are less likely affected by jello or vibration issues compared with CMOS security cameras, since CMOS security cameras use “rolling shutter” — it means the security camera exposes from top to bottom.

RT was formed in 2005, funded by the Russian government. Originally called Russia Today, it has different language channels, including English, Arabic, Spanish and French.

But that is not the full story. Media watchdogs and disinformation analysts have long pointed to how Russia and China seek to gain a foothold in Africa, using free content and funding with local media as a sweetener.

CCTV security camera CMOS and CCD image sensors, which one is better? What are the differences between CCD and CMOS image sensors on security cameras?

In a word, security cameras with CMOS image sensors offer much higher frame fate and consume less power, and are more cost-saving compared with security cameras with CCD image sensors. Normally CMOS CCTV security camera price would be more favorable than CCD security IP cameras.

RT has made inroads elsewhere on the continent, establishing a bureau in Algeria last year. Also last year, Afrique Media in Cameroon signed a partnership with the Russian network.

And Russia is the leading source of disinformation on the continent, the Africa Center for Strategic Studies said. Its March 2024 report found a nearly fourfold increase in disinformation campaigns targeting African countries, with an aim of "triggering destabilizing and antidemocratic consequences."

“In Francophone Africa, they put forward a very anti-West, very anti-French line. Also very, very involved in social media campaigns and disinformation, exacerbating local grievances,” Gruzd noted.

“I think the collective antipathy towards colonialism, which is deeply ingrained in African populations, is a string that Russia is pulling,” said Gruzd.

It has often been described as a propaganda outlet and has been found by media regulators like Britain’s Ofcom to lack impartiality and broadcast “misleading” material. In 2017, it was forced to register as a foreign agent in the United States.

Security camera CMOS image sensor is a real winner on frame rate. Security camera CMOS image sensor can directly convert the photoelectric signal to digital signal. The frame rate and process speed is extremely fast compared with CCD image sensors.

According to RT’s website, the channel can also be viewed in Kenya, Tanzania and other African countries through China’s StarTimes service. It can be seen on satellite or the internet in Zimbabwe, Ethiopia and elsewhere.

Asked by VOA whether he thinks the campaign will resonate with Africans, he said it was hard to know what proportion, but judging by pro-Russia and anti-Western sentiment on African Twitter/X, there were certainly some people on the continent with whom it would resonate.

“Pervasive western mainstream media dominance is something that RT has had to battle for nearly two decades,” RT deputy editor-in-chief Anna Belkina said in a recent op-ed on the rationale behind the campaign.

“I think there would be some sympathy for this line and some support for it,” Gruzd said. “On the other hand, I think there are a lot of people who see through this and can see the agenda behind what is being promoted.”

“Your Values. Shared,” promise billboards highlighting Julius Nyerere, Tanzania’s first president; Ugandan independence leader Milton Obote; and former Ghanaian leader Kwame Nkrumah.

An image sensor is the “eye” of your IP security cameras. A security camera image sensor can capture the light hitting the security camera lens, and convert it into electronic signal. Thus you can see the images/videos when you access your IP security cameras.

However, with the developing technology on security cameras CMOS image sensors, the image quality of CMOS image sensors can be on a par with CCD image sensors in CCTV IP surveillance cameras.

If you want to buy a security camera with a good image sensor for clear-crystal images/videos, you should never miss the security camera CMOS and CCD image sensor comparison below.

In a press release, the television network said the campaign “emphasizes RT’s commitment to [the] dismantling of neo-colonialist narratives in news media.”

“There is a huge irony in RT promoting itself as a voice of anti-colonialism at a time when Russia is increasing its influence on the continent in ways that could be described as neo-colonial. One thing we know about RT is that it is not an African voice, but Putin's outlet, there to serve him and his country,” Harber said. “So, it is dressing up its ambitions for influence in, with a paternalistic anti-colonial rhetoric.”
