  • What is CCTV?

    CCTV stands for Closed Circuit Television. It is a video system that consists of strategically placed video cameras around an area that records footage, and is then transmitted to a display monitor(s) for real-time viewing as well as footage playback.


    It refers to all aspects and components that make up the system, such as the camera, wiring, video footage storage (via the cloud or digital video recorder), monitors, access control and general system management.

    You would want to use a CCTV system to increase the security of your business premises and have surveillance on key areas at any one time. This would be particularly useful for large premises or one that holds valuable equipment, products or information.

    As well as recording video footage, a CCTV system can also notify you if there is activity or movement on a certain camera at a set time. For instance, in the dead of night whilst the business premises in closed and employees have gone home. This notification could indicate that someone may be about or looking to break-in to your site.

    Although a CCTV system can be used for the surveillance of on-site activity, during and out of working hours, it can also be used to help identify wanted criminals, as well as act as a deterrent to potential intruders.

    How Does CCTV Work?

    Want to know the ins and outs of how a CCTV system works? It’s not complicated, but it does vary depending on the type of system you install and the components used. However, the overall process is the same.

    Consisting of at least one camera, lens, monitor and recorder, a CCTV system can be scaled up or down depending on the size of area wanting surveillance. CCTV works by the camera or cameras taking a constant sequence of images that are then transmitted by cable or wirelessly (depending on the chosen system type) to the recording device and then on to the display monitor, which enables an individual to see the sequence of images as video footage. Depending on the type of cameras used, they may also have the ability to zoom in and out and rotate 360 degrees.

    As mentioned previously, there are many types of CCTV systems with various cameras that have a number of uses, such as night vision, thermal imaging and number plate recognition.

    The two main types of system are:

    Wired: Cameras and the rest of the system is wired

    Wireless: No wires are needed as the system works via an internet connection.

  Unmanned Power Sub Station System An Unmanned Power Substation System refers to a modern and technologically advanced electrical substation that operates without the need for constant on-site human presence. These unmanned substations utilize automation, remote monitoring, and control technologies to efficiently manage potential events. Automation and Remote Control The system is equipped with intelligent devices and sensors that automate various tasks such as monitoring voltage, current, temperature, and other parameters. Remote control capabilities allow operators to manage the substation from our command center. Reduced Operation and Maintenance Costs With the elimination of on-site personnel, the operational and maintenance costs associated with manned substations are significantly reduced. Routine maintenance tasks can be scheduled and monitored remotely. Enhanced Reliability and Safety The use of automated systems ensures greater reliability and minimizes the risk of human ...

Difference Between AC And DC Motor

  Difference Between AC And DC Motor The difference between AC and DC Motor are discussed below: AC Motor vs DC Motor AC Motor DC Motor AC motor runs on alternating current. DC motors operate on direct current. There is no need for conversion of current in AC motors. Like AC. There is no need for conversion of current in AC motors. Like AC. AC motors are used where power performance is demanded for extended periods of time. DC motors are used where the speed of the motor needs to be controlled externally. AC motors can be single-phase or three-phase. All DC motors are single phase. In an AC motor the armature does not rotate while the magnetic field keeps rotating continuously. In a DC motor, the armature rotates while the magnetic field rotates. Repairing AC motors is not expensive. DC motors are very expensive to repair. Brushes are not used in AC motor. Brushes are used in DC motor. AC motors have a very long life span DC motors do not have a very long life span. The speed of AC...

  What is MOSFET? The MOSFET, also known as a metal-oxide-semiconductor field-effect transistor, is a type of FET with an insulated gate that is assembled by the controlled oxidation of that  semiconductor . The semiconductor used in it is generally silicon. In more detail, we can explain that it is a four-a terminal-based device that is composed of a, Source(S) Gate (G) Drain (D) Body (B) In a general overview, the body of a MOSFET is in connection with its source terminal hence forming a three-terminal device such as a field-effect transistor. It is normally considered a transistor and is utilized in both digital circuits and analog circuits. A MOSFET can function in two ways Depletion Mode Enhancement Mode Enhanced Mode Enhanced mode can be defined as if there is no voltage across the gate terminal then the device will not conduct. But when there is a maximum voltage present across the gate terminal then the conductivity of the device gets enhanced. Depletion Mode Depletion...
