UAE Guide to CCTV Installation System

CCTV Installation System

Al-Mazrooei Security systems LLC Over the past several years, Closed Circuit TV (CCTV) systems have significantly improved in standards due to technological advancements. Commercial operations and even residential residences now have easy access to high-end security systems at affordable prices.

In contrast to “regular” television, which is broadcast to a much wider audience, “closed-circuit” television transmits a limited number of monitors (closed-circuit). Detecting and deterring criminal activities and recording traffic infractions are two of the most common uses of CCTV networks, but they also have other uses.

Al-Mazrooei Security systems LLC is offering five features you may not know about CCTV systems

  • Installing CCTV Night Vision System

High-end cameras used to have this feature and even then, it was questionable as to its quality. In the modern era of CCTV, professional (but residential-based) systems are capable of detecting people within 20 meters and having a 50-meter visibility range. For most applications, such systems use infrared night vision technology. It is more appropriate to use thermal imaging when more advanced night vision is needed. A thermal radiation is generated by every object that has a temperature greater than absolute zero, even if it is only minimal. Thermal imaging sensors can detect this type of radiation, which is invisible to the human eye. Temperature differences between surroundings and objects can be detected by thermal cameras, which produce visual images. Larger differences result in greater contrast variety, allowing you to see more details. Al-Mazrooei Security systems LLC installing CCTV Thermal cameras which are more suitable for challenging environments than visible light cameras. 

  • Installing CCTV Motion Detector System

Al-Mazrooei Security systems LLC installing CCTV Motion Detection systems which are used in monitoring of conveyor belts that needs to be used motion detection . Motion detection is now part of almost every IP-based CCTV system which is offering by Al-Mazrooei. Motion detection allows the modern systems to increase the amount of time recordings can remain on the recorder by only keeping recordings that have been detected as moving in the frame. Moreover, the system can be configured to ignore certain parts of the frame, such as trees and flags, to make sure the wind does not interfere with your security. A motion detection system can be used in warehouses and commercial applications to detect dangerous behaviors and instances where people are in areas where they shouldn’t be. This technology is frequently used by 360 Secure to monitor workplace safety and health for manufacturing and warehousing clients. We are among the few CCTV suppliers in UAE who work closely with our clients to provide them with these types of benefits.

  • Installing CCTV IP (Internet Protocol) System

There are two types of CCTV cameras, IP and AHD-TVI, which you may encounter when selecting one. However, IP is by far the best technology in terms of picture quality and flexibility, regardless of the fact that some suppliers will push AHD-TVI cameras as they may be slightly cheaper. With IP cameras, the quality of video footage is significantly improved and the video can be compressed to retain higher quality video footage for a longer duration. In addition, IP cameras can be used in other areas of a “Smart Home”, such as a remote access camera that is connected directly to the internet, rather than through an NVR, and this can provide additional flexibility for large installations.

  • Providing Remote Accessibility

To ensure your property is safe, what time of day would you choose to check your security cameras? It’s obvious when you aren’t at home. Modern security camera installations include remote access capabilities as standard features. Al-Mazrooei in most residential systems providing with four or eight cameras, there will be an NVR (Network Video Recorder) that comes with a phone app which provides full control of all the cameras from your phone in a secure manner to assure you are the only one watching. We are providing more advanced features, such as raising alarms and unlocking doors, you can either use a NVR or separate software installed on a server.

  • Installing CCTV PTZ (Pan, Tilt, Zoom) System

Remote directional and zoom capabilities are provided by a PTZ camera. It is typically only found on higher-end models, but most residential cameras come with this feature. A feature like this is obvious in its benefits, as it allows owners to zoom in on activity happening without having to manually adjust the camera angle. For cameras installed at height, PTZ can provide a wide-angle view while providing close inspection through the Zoom function, as well as maximum visibility at a wide angle. 

Applications Of CCTV

Management of crime

Potential criminals can be deterred by CCTV surveillance. Using video footage to help investigate crimes and later provide evidence in court can be extremely helpful to law enforcement. Sensors such as audio, thermal, and other types can be used with CCTV to alert officials to abnormal occurrences, such as fires or gun shots. CCTV cameras can be used by businesses to detect and monitor criminal activity within their own facilities. Video surveillance may be used by prisons to prevent the delivery of drugs and other contraband by drones. Inaccessible areas, such as rooftops, can be monitored by security cameras.

Management of disasters

By using CCTV cameras, disaster management teams can monitor events such as a burning building, a cave, or a helicopter flying over the area in real-time so they can prepare for disasters.

Street monitoring in cities and communities

Traffic lights and other city locations have cameras that monitor people for speeding statistics and other evidence. AoT is one of the most recent initiatives of Chicago that aims to collect real-time data about the city’s weather and environment. Security cameras that record images are included in some sensory nodes, but they are not transmitted or stored to protect the privacy of users. Researchers use a limited number to develop computer vision software, which is stored in the main for use by senior researchers.

Monitor and diagnose medical conditions

Humans express their thoughts and feelings through 43 facial muscles. Images can be identified more easily by smart software, such as pain or anxiety, than by people. In addition to monitoring patients – such as children or the elderly – CCTV cameras can identify potential medical crises, such as strokes, epileptic attacks, or asthma attacks.

Studying human behavior

In a study examining suicide attempts, CCTV footage detected specific behaviors in 83 percent of people who tried to jump in front of a train. Later, CCTV footage was analyzed to identify potential suicides and be used to alert monitor watchers. In order to prevent anti-social behavior in public places, researchers also use surveillance networks to record crowd activities. In schools, cameras may be used for security purposes and for video recording of incidents such as bullying or playground fights.

Analytics for the retail industry

Video surveillance of customers provides market intelligence that is being used to improve strategy, such as identifying how people shop, which aisles they frequently traverse, and how likely they are to respond to calls to action in different store layouts. A heat map can be used to determine peak shopping times, preferred promotions, and staffing requirements for peak shopping periods by showing highs and lows in shopper traffic at specific locations in a store.

Working Principle of CCTV

Modern CCTV networks convert analog systems to digital using conversion software and hardware. Analog and digital systems work differently. Retrofitting is a process that accomplishes this goal.

CCTV systems typically include the following components:

  • A camera (analog or digital) with an image sensor attached to its lens
  • Analog systems require a video tape recorder; digital systems require a Direct Video Recorder (DVR) or Network Video Recorder (NVR).
  • For digital, use RJ45 cables or coaxial cables for analog
  • Images are transmitted to one or more monitors

CCTV Systems

  • Analog

Continuous video signals can be transmitted using coaxial cables with Bayonet Neill-Concelman (BNC) connectors. However, they are relatively cheap and effective despite their low resolution. Standard coaxial cables do not usually transmit audio in an analog system, as analog systems have more peripherals. With older equipment, it is more cost-effective to convert analog signals to digital. Computers or tape recorders can store the images, provided they have a video capture card. A step up from traditional HD systems (1080 pixels), analog HD provides improved resolution and is backwards compatible with analog cameras as well as BNC connections.

  • Digital

Make cameras digital by digitizing signals. The images are stored directly on a computer, so there is no need for a video capture card, but recordings require a considerable amount of space, so they are typically heavily compressed.

  • Network or IP

Streaming video over the Internet is possible with these systems when used with analog or digital cameras. Advantages of WiFi and audio are Distributed Artificial Intelligence, analyzing images, wireless connectivity, Ethernet power and higher resolution. In addition, IP cameras are capable of containing more cameras in one, allowing them to cover a wider area than it would require multiple cameras or systems.

With IP camera systems and digital video cameras becoming more prevalent, all three options continue to be equally used.

Components of CCTV

  • Encoders

By incorporating video encoders into some network systems, analog CCTV systems can be moved to a more cost-effective system with modern features and hardware. Wired or wireless IP-based systems can be connected via the software, which converts video signals into digital signals.

 

  • Sensors for imaging

Images are converted into electronic signals by cameras using different types of image sensors. The amount of light exposed to a sensor is detected by multiple photodiodes, which then convert it into electrons. Complimentary metal oxide semiconductors (CMOS) and charge coupled devices (CCDs) are the two most popular formats.

  • CMOS

Sensors equipped with CMOS technology are less expensive than those equipped with CCD technology. A megapixel CMOS sensor (which utilizes millions of pixels) may even compete with CCD sensors in terms of quality.

  • CCD

In terms of cost and power consumption, CCD is the more expensive option. Generally, CCD scanners perform better in inclement light (they are more sensitive to light) and are quieter than CMOS scanners. A conversion device converts the analog signal into numeric values, so it can be transmitted.

 

  • Analyzing images

The digital CCTV industry uses interlaced scanning methods for CCD sensors (instant exposure) while CCDs and CMOS can use either progressive or interlaced scanning methods. Interlaced scanning is the only scanning method used by analog cameras.

 

  • Interlaced for CCD Applications

A TVL (line) is transmitted from an image in odd and even sequences. High resolution cameras have at least 700 lines, and cameras with more than 400 lines provide good resolution. By continuously refreshing the transmissions, the human brain believes they are viewing a single, complete picture, reducing bandwidth. Interlaced recordings may appear jagged on progressive scan monitors, but not on interlaced monitors. To view interlaced scans on analog monitors or progressive scan monitors, modern video software first de-interlaces interlaced scans into progressive scans.

 

  • Progressive for CMOS applications

The image is not divided into fields (odds and evens). Scannable images are exposed sequentially on a monitor by scanning each line (field).

  • Video Recorders

In CCTV systems, DVRs connect to a variety of internal components rather than to external networks. An analog camera is usually connected to a DVR. DVR systems require direct connections between each camera and recorder. A DVR system processes footage from the camera, while an NVR system works at the camera level, and streams data to a recorder, which stores it and allows you to monitor it remotely. IP cameras are commonly used in NVR systems. IP cameras are connected to the same network in an NVR system.
