Every home should have a CCTV camera. CCTV has many positive effects. CCTV cameras should not be limited to business places and offices only. They should be in homes to safeguard life and property. Some criminal intentions will not be carried out if the perpetrators see a CCTV camera on the premises.
Additionally, CCTV cameras can watch the activities of children when their parents are away. Parents can use their smartphones or monitors to see these activities. CCTV provides real-time 24/7 viewing access. Closed-circuit television (CCTV) records images of people in certain public places including town centres, roads, airports, and on public transport. CCTV images can be used as evidence in court. You can ask for CCTV recordings of yourself if there’s a need to.
CCTV stands for closed-circuit television. It is a TV system where signals are transmitted and monitored. The primary use is for video surveillance and security.
SOME HISTORIC CCTV MOMENTS
- By 1974 – The Start of Using CCTV for Traffic Monitoring in London. Surveillance cameras are installed to monitor traffic. They are set up on major roads that run in and out of London.
- 2000s – Digital Video Recorders
Progress in digital technology since the early 2000s has led to VCRs being replaced with Digital Video Recorders (DVRs), which allows CCTV to be more user-friendly. Multiplexers, from the early 90s, are now built into these solutions, meaning kits are easier to install and operate. The other advantage of digital systems has removed the need for videotapes and the storage of them.
- 2007 – Major Brands Release IP Cameras
Samsung, Panasonic, and Sony release high-performing IP cameras to the market.
- 2015 – 4K
4K cameras entered the market and provide incredibly high-resolution images.
The world of CCTV has seen a meteoric rise since its invention. It will continue to improve in the years to come. Walter Bruch invented CCTV. It was first used in 1942 in Germany to capture live video footage. Operators used these early forms of CCTV in wartime to monitor V-2 rockets. It wasn’t until seven years later, in 1949, that CCTV became available commercially.
TYPES OF CCTV
CCTVs and surveillance cameras come in many configurations. Some offer IP connectivity. Others provide coloured or black-and-white night vision.
The 9 most popular types of CCTV cameras available are:
- Dome CCTV Cameras
- Bullet CCTV Cameras
- C-Mount CCTV Cameras
- PTZ Pan Tilt & Zoom Cameras
- Day/Night CCTV Cameras
- Infrared/night vision CCTV Cameras
- Network/IP CCTV Cameras
- Wireless CCTV Cameras
- High Definition (HD) CCTV Cameras
CCTV cameras can be categorized by their lens type, such as fixed lens or varifocal lens.
CCTV won’t work without electricity. CCTV can be powered wirelessly, through battery or solar means. So you either use electricity or solar.
The 5 essential components you need to give importance to for consistent service are: Camera, Monitor, Cable, Video Recorders, and Data Storage.
If you’re building a CCTV Camera System, there are two camera options: Internet Protocol (IP) or analog. IP is usually the preferred choice due to its compatibility with most devices. Many types of cameras can be installed, for example – dome cameras, bullet cameras, covert cameras.
Depending on how many angles you want to cover, how many cameras you will need in that specific area, how much resolution or detailing you require when you choose your preferred cameras.
The surveillance industry is valued at around $70 billion dollars with a prediction to double by 2030.
Cameras generated the higher hardware revenue in the video surveillance market, of about $17 billion, in the year 2021, which will increase at a rate of about 12% in the near future. This is due to the increasing requirement for security cameras that offer a combination of the video analytics and deep learning technologies for an extensive variety of purposes.
Highlighting the roles of AI in CCTV systems
AI CCTV cameras offer a considerable improvement in accuracy compared to traditional surveillance systems. By leveraging machine learning algorithms, these cameras can remove irrelevant information and focus on potential threats accurately. Some of the benefits are listed below:
- improved motion detection
- Facial recognition
- Behaviour analysis
- License plate recognition
- Environmental Monitoring
- Object recognition
- Intrusion recognition
- Cost-effective solutions
- Crowd density analysis
- Ethical approach
Some of the best security cameras for AI include the Canary Pro, Nest Cam IQ Indoor, Ring Stick Up Cam Wired and Arlo Pro 3.
AI-driven video analytics allows for real-time tracking, counting of people, and computerized identification of license plates and offers administrative authorities data related to non-security aspects.
Artificial intelligence seems to be the hot topic not just in the world of surveillance, but in the world of digital technology overall. This new technology is able to adapt quickly and methodically to changing situations, is able to record and analyze vast amounts of data, and can “think” through problems to lessen errors.
In conclusion, camera surveillance has become a vital necessity in this modern age to help prevent and detect crime. The benefits to public spaces and homes are undeniable.
