COURSE DESCRIPTION

CCTV stands for closed-circuit television and is commonly known as video surveillance. “Closed-circuit” means broadcasts are usually transmitted to a limited (closed) number of monitors, unlike “regular” TV, which is broadcast to the public at large. CCTV networks are commonly used to detect and deter criminal activities, and record traffic infractions, but they have other uses.

CCTV technology was first developed in 1942 by German scientists to monitor the launch of V2 rockets. It was later used by American scientists during the testing of the atomic bomb.

CCTV applications

Crime management

CCTV surveillance can deter potential criminals. When a crime does occur, video footage can help law enforcement to investigate and later provide evidence for prosecution in a law court. 

Disaster management

Using CCTV cameras, emergency services and rescue workers are able to assess and monitor events in real time to relay a “situation” via video to disaster management teams, e.g. from inside a burning building, from a cave or from a helicopter flying over a scene.

City and community street monitoring

Cameras at traffic lights and elsewhere in cities monitor people to gather traffic statistics as well as evidentiary footage for speeding. 

Medical monitoring and diagnosis

There are about 43 facial muscles that express people’s thoughts and feelings. Smart software can identify these expressions, e.g. pain or anxiety, from images more easily that people can. CCTV cameras can also monitor patients – for instance children or the elderly – to identify potential medical crises, e.g. a stroke, or an epileptic or asthma attack.

Behavioral research

CCTV used to research suicide found that 83 percent of people attempting to throw themselves in front of a train showed specific behaviors. These were later analyzed from CCTV footage and are now used to alert monitor watchers to potential suicides. Surveillance networks are also used by researchers to record crowd activities in public places and prevent anti-social behaviors. For instance, cameras have been used at schools for security, and to record bullying or playground incidents on video.

Retail intelligence

Market intelligence garnered from video surveillance of customers is being used to analyze buying trends and enable enhanced strategizing. also use to fight against stealing from the shops.

Types of CCTV systems

• Analog - Use Bayonet Neill-Concelman (BNC) connectors on coaxial cables to transmit continuous video signals. They are relatively low resolution but cheap and effective. There are more peripherals in an analog system, e.g. standard coaxial cables don’t usually transmit audio. Analog signals can be digitized, making it more cost-effective to go digital even with older equipment. The images require a video capture card and can be stored on a PC or tape recorder. A step up, analog HD enables increased resolution over traditional systems (1080 pixels) and are backwards compatible with analog cameras and BNC.
• Digital – Digitalize signals at camera level. These systems don’t require a video capture card as images are stored directly to a computer but require a (relatively) large amount of space to store recordings, so they are usually heavily compressed.
• Network or IP – Used with analog or digital cameras, these systems utilize a video server to stream footage over the internet. The advantages are the possibility of WiFi and audio, Distributed Artificial Intelligence (DAI) for analyzing image footage, remote access, Power Over Ethernet (POE), and better resolution. Furthermore, IP cameras have the ability to contain more cameras in one, which can cover a wide angle that may normally take multiple cameras or camera systems to cover.

All three options are still equally in use, with a high tendency to IP camera systems and digital video cameras.

Network CCTV pros and cons

Pros – Enable remote monitoring, don’t require network cabling, highly mobile and enable the automation of surveillance processes

Cons – Can be expensive to buy out of the box, entail a higher learning curve and are at risk from hackers

Analog CCTV pros and cons
 

Pros – Cheaper and easier installation than network CCTV with more vendor support available

Cons – Lower resolution, more cabling required and don’t facilitate data encryption

The training will cover the following areas of CCTV

1. Analog CCTV Installation
2. IP/Network cameras CCTV Installation
3. Network cable termination
4. PVC pipe handling and laying of cables on walls, ceillings and underground.
5. How to install CCTV onto mobile phones
6. Field tour to installed sites, especially underground cabling sites.
7. Basic introduction to electrical works to prevent dangers during and after installations.

After the training participants should be able to install CCTV cameras being analog or IP camera.

Participants will receive manual, T-Shirt, some TLMs

All participants who need accommodation should contact our office number for arrangement at a fee.
