Explore the composition of the monitoring equipment system from four o'clock

[ Huaqiang Security Network News ]
The continuous advancement of modern science has promoted the vigorous development of monitoring equipment systems. It can not only greatly reduce the management costs of personnel, but also provide a more secure environment more intelligently, especially with the continuous development of computers and multimedia technologies in recent years. This technology will be more advanced, and the monitoring equipment system has become an important part of security.
Explore the composition of the monitoring equipment system from four o'clock
For the composition of the monitoring device, we can analyze it from four points.
The first point: the control part. The function of the control part is to remotely control the field devices of the system through the relevant equipment in the execution room. Controller and microcomputer controller in the main equipment of the control part.
The second point: image processing and display part. Image processing refers to the allocation, switching, recording, playback, processing and copying of image signals transmitted by the system. In the display section, the display is performed using a monitor or a monitor. The main devices in the image processing and display section are video controls/switchers, displays, monitors and recorders.
The third point: transmission equipment. The function of the transmission part is to feed the video (and sometimes audio) signals from the camera to the center to control the work of the live camera, lens, pan/tilt and shield. There are two types of video signal transmission methods: one is wired transmission using cable, such as coaxial cable, balanced pair cable, optical cable, telephone line, network cable, etc.; the other is UHF, microwave, and millimeter. A wireless method of transmitting waves, etc.
The fourth point: the camera section. The function of the camera part is to convert the target (video image) monitored by the system into a detection signal, and then send it to the control center through the transmission part of the system for control and processing, and restore it to the originally monitored image signal. It can also be recorded and saved if needed. The core of the camera section is the camera, which is the main device for photoelectric signal conversion.

PC plastic,full name Polycarbonate.

PC plastic is a kind of excellent comprehensive performance engineering plastics.It has excellent physical, mechanical, electrical, and thermal properties,so it's known as the "king of the transparent plastic'

 

Classification:

Anti - static PC SHEET, conductive PC SHEET,fireproof PC SHEET,PC fiber - resistant, PC GF SHEET, PC+ABS SHEET,anti-ultraviolet ray resistance PC, food grade PC, anti - chemical PC.

 

Advantages:

1,Light weight

2,Impact resistance

3,Excellent physical, mechanical, electrical and thermal properties

4,Ultraviolet resistance

 

Disadvantages:

Polycarbonate is not resistant to ultraviolet light, no resistance to alkali, resistance to hydrolysis stability is not high, is the main performance defect is sensitive to the gap, resistance to organic chemistry, scratch resistance is poorer, long-term exposure to ultraviolet light yellow, are vulnerable to the erosion of some organic solvents.

 

Applications:

1. Dust-free room spacer

2. Equipment shield and test fixtures;

3. Commercial Building Lighting;

4. Soundproof walls;

5. Greenhouse;

6. Components for medical and pharmaceutical devices;

7. Face shields;

8. Skylights, etc

 

Modified use:

The purpose of the modified PC Plastic is to toughen, improve the processing performance, reduce the residual deformation, and increase the flame retardancy, etc.

PC/ABS can improve bending modulus, heat resistance and plating performance.

PC/PET and PBT can improve drug resistance and solvent resistance.

PC/PMMA added plexiglass to enhance the appearance of pearlescent color.

PC/PA and HIPS can improve impact toughness and surface finish.

PC/HDPE can improve water resistance, aging resistance, weather resistance and LDPE.

The PC  Plastic USES fiberglass or carbon fiber to enhance modification and improve mechanical strength.

The flame retardant grade  PC  Plastic  can be made with bromine flame retardant and antimony trioxide.

Other and polysulfone, aromatic polycarbonate, polyvinyl formaldehyde, polypropylene, polystyrene can be modified to achieve the balance between economy and performance.


 

Combustion characteristics: 

Combustion condition: easy, softening foaming

Flame status: small amount of black smoke

After the fire: out of the fire

Bouquet: no special taste

 

Specification: the thickness of PC  Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of 10-180mm is 600*1200 mm.  PC Plastic sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.and The diameter of the PC Plastic rod can be produced from 2mm to 250mm, the length is 1 meter, and it can be ordered to be more than 3 meters in length.

Color: Black and clear, can also be made another color, and the color order is 500KG.


Modified varieties:PC Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.

Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
