There are various types of CCTV cameras such as dome, bullet, PTZ, thermal, and covert cameras.

• Dome cameras are commonly used for indoor surveillance and have a wide-angle view.

• Bullet cameras are weatherproof and have a longer range than dome cameras.

• PTZ cameras can pan, tilt, and zoom to cover a larger area.

• Thermal cameras use heat signatures to detect movement and are often used in low-light environments.

• Covert camer...read more

A multimeter is an electronic device used to measure voltage, current, and resistance in electrical circuits.

• It can measure AC and DC voltage

• It can measure AC and DC current

• It can measure resistance

• It can also measure other electrical parameters such as capacitance and frequency

• It typically has a digital display for easy reading

• Examples of multimeter brands include Fluke, Klein Tools, and Extech

Bernoulli theorem explains the relationship between fluid velocity, pressure, and elevation.

• Bernoulli theorem states that as the velocity of a fluid increases, its pressure decreases.

• It is based on the principle of conservation of energy in fluid flow.

• The theorem is commonly used in fluid dynamics and aerodynamics.

• It can be applied to various situations like flow through pipes, airfoils, and nozzles.

• For example, when w...read more

AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction.

• AC stands for Alternating Current and DC stands for Direct Current.

• AC changes direction periodically, typically at a frequency of 50 or 60 Hz.

• DC flows in one direction continuously.

• AC is used for power transmission over long distances.

• DC is commonly used in batteries and electronic devices.

• AC can be easily c...read more
