  LCDLCD (Liquid Crystal Display), also known as liquid crystal display, is a flat ultra-thin display device composed of a certain number of color or black and white pixels, placed in front of a light source or reflective surface. LCD displays have low power consumption, making them highly favored by engineers and suitable for electronic devices that use batteries. Its main principle is to stimulate liquid crystal molecules with electric current to generate dots, lines, and surfaces, which are combined with the back light tube to form a picture.

The monitor is a component of the closed-circuit monitoring system (CCTV), serving as the display part and standard output of the monitoring system. With the display of the monitor, we can view the images sent by the front-end. As an indispensable terminal device for video surveillance, it serves as the "eyes" of surveillance personnel and also plays a critical role in post surveillance investigations.

Remote power monitor refers to a device that can remotely control the power on or off of equipment through telephone or network.

There are currently three main ways to achieve remote control: mobile/telephone voice prompts, mobile GPRS/INTERNET network remote control, and computer software control.

The differences between monitors, televisions, and displays are mainly reflected in three aspects of performance: image clarity, color reproduction, and overall stability.

Regarding the special and specialized use of monitors, when choosing LCD displays, more attention should be paid to the performance of the LCD screen, such as response time, clarity, color reproduction, viewing angle, overall stability, service life, and so on.

Visual area: When purchasing a LCD monitor, the first consideration is the "face" size.

Response time: The biggest selling point of LCD monitors is the continuously improving response time, from the initial 25ms to the current 4ms grayscale, the speed improvement is astonishing

Image color:

1. The brightness of a LCD monitor refers to the brightness of the display screen

2. The ratio of the brightness of the same point on the LCD screen at its brightest and darkest is the contrast of the LCD monitor

3. Color gamut is a method of encoding a color, and also refers to the sum of colors that a technical system can produce.
