Hello, it is recommended that you find the building weak current engineering design and construction manual on the Internet.

Monitoring jargon.

1. PDVR: Digital Hard Disk Video Recorder.

2. NVR: Network DVR.

3. IP-SAN: storage local area network.

4. IR-CUT: Dual filter switching.

5. PTZ: PTZ and lens zoom control.

8. Compression encoder: further compress the digital signal of the audio without attenuating the audio signal.

9. Signal-to-noise ratio (SNR): also known as signal-to-noise ratio, refers to the ratio of the voltage of the signal output by the amplifier to the noise voltage output at the same time.

10. There are currently two scanning methods for the scanning mode of the camera, namely: PAL (progressive inverted image orthogonal balance modulation system, generally 25 frames per second. At present, most of China is based on this system) and NTSC (orthogonal balanced modulation system, generally 30 frames per second).

At present, Japan generally uses this system).

11. Horizontal resolution: also called horizontal clear line, it is an index to evaluate the resolution of the camera, the horizontal resolution of the black and white camera is about 380-600 lines, and the horizontal resolution of the color camera is between 320-500 lines.

12. Automatic gain control: also called AGC, the process of automatic adjustment of the gain of the amplifier. This is usually done so that the output signal level changes less as the input signal level changes.

13. White balance: White balance is a very important concept in the field of TV photography, through which it can solve a series of problems in color reproduction and tone processing. White balance is created as electronic images reproduce color truth.

14. Auto white balance: Auto white balance is usually the default setting of digital cameras, and there is a complex rectangular diagram in the camera, which can determine the white balance reference point in the picture, so as to achieve white balance adjustment.

16. Screen splitter: also known as the splitter for monitoring screens, there are generally 4 divisions, 9 divisions, 16 divisions, etc.

17. Classification of power supply of the camera:

220V AC and 1110V AC (NTSC standard mostly uses this power supply method).

24V AC, 12V DC (currently most of the domestic use of this supply), 9V DC

18. Amplifier: It is to amplify the signal to enhance the brightness, chromaticity and signal synchronization. Note: Do not string too many amplifiers in the same channel, otherwise saturation will occur, resulting in image distortion.

22. IP protection level: The IP protection rating system is drafted by the IEC.

Commonly used security terminology:

01security: Security protection for life, property, environment, information, etc.

02Security systemA series of systems that work together to protect life, property, environment, and information in an isosceles triangle.

03Alarm: A signal or other signal generated to attract attention when there is a predetermined danger to life, property, environment, information, etc.

04false alarm: An alarm caused by reasons other than the intent of the warning.

05Operation signal: A signal that indicates the status of the system engineering.

06tamper device (tamper function) is a function designed to detect vandalism to safety alarm equipment.

07 Security equipment: Equipment for the purpose of preventing crime.

08burglar alarm systemA manual or automatic alarm device used to prevent crime.

09normal closeIn the alert state, the system alarm output component contact is "closed".

10Normal open (normally open) In the alert state, the system alarm output component contact is in the state of "open circuit".

Hope it helps!

Meng scholars interpret history and culture and spread positive energy. w

1 All 1, wall bracket integrated waterproof power box: Combine the wall bracket with the waterproof power box, and the waterproof power box is installed with a DC 12V 3A power board.

2. Active external circulation to the heat dissipation device: It is a heat dissipation device, the principle of which is estimated to use the fan and thermal conductive materials such as copper and aluminum to transfer the heat in the camera.

3. Wall-mounted (including integrated waterproof power box): It means that when the wall-mounted method is adopted, his "wall-mounted bracket integrated waterproof power box" is used

4. Hoisting (with a waterproof power box): It means that when the hoisting method is adopted, the bracket and the power box are separated

It is recommended that you go to Dabit Business Network to take a look, remember that there is a special "security" channel there.
