Model composition and representation >>

     The surveillance video cable is a wire and cable for connecting a security surveillance camera and a real terminal (computer or display, etc.), and its function is to transmit image data captured by the surveillance camera. The surveillance video cable is a type of coaxial cable, also called coaxial video cable, the letter code is SYV, so it is also called SYV cable or video coaxial cable.

The surveillance video line has good anti-interference, uniform impedance, good moisture resistance, long service life, low attenuation, low capacitance, high transmission, stable structure, etc. It is widely used at present and is closely related to our life. In the community, in the office building, in the street, and so on, you can see the surveillance camera, of course, with the surveillance video cable. Therefore, monitoring video lines provides us with good security.

According to different specifications and functions, the monitoring lines can be divided into several types: SYV series, TSYV series and SYWV series. The following are detailed descriptions of several types -



— — — — — — — — — SYV Series: RF Coaxial Cable — — — — — — — — —


First, the product introduction:


SYV, full name: copper core solid polyethylene insulated PVC sheathed coaxial RF cable, which is a cable wrapped by a layer of insulated wire wrapped around the central copper conductor. The minimum bending radius is allowed: the outer diameter of the cable is not less than 5 times in the room, and the outer diameter of the cable is not less than 10 times in the outdoor.

Second, the basic parameters of the product:


Resistance:75Ω

Conductor:1×0.75mm, using high-purity oxygen-free copper, low signal transmission attenuation

Insulation:

High quality foamed polyethylene

Shield:

Aluminum foil + high density copper woven mesh

Jacket layer:

High quality polyvinyl chloride (PVC)

— — — — — — — — —TSYV series: Integrated cable for elevator — — — — — —

First, the product introduction:

TSYV elevator integrated cable, also known as elevator video cable, is mainly suitable for video transmission and signal control of elevator monitoring system. The elevator integrated cable is composed of coaxial cable, which has reinforced steel wire and nylon rope, and fibrous structure. The outer sheath is made of super soft PVC material, which effectively increases tensile strength and flexibility. It has long service life, stable video transmission model and high definition.


Second, the basic parameters of the product:

Resistance:75Ω

Inner conductor:Stranding with multiple tinned copper wires

Material:Cable reinforced tensile steel wire and fiber

Instinct:Solid core polyethylene insulation or PVC insulation

Shield braiding:Tinned soft copper wire braided shield

Outer package

Aluminum foil shield

Guard layer

High quality polyvinyl chloride (PVC)

Long-term allowable operating temperature

Not more than 70 ° C


Third, product performance:

Since the elevator car is a nearly closed narrow space, and there are many cables such as control, lighting, fan, etc. in the elevator room, it is difficult to make the wiring of the video cable. According to the actual analysis, the following principles should be followed in the selection of the integrated cable for the elevator.

1. Meet the tensile strength: Half of the elevator cable is used for extension. The high-rise elevator can reach more than 100 meters, and the self-weight of the one-meter cable is nearly 

100 kilograms, so the cable must have sufficient tensile strength. Nowadays, there is a self-supporting flat composite elevator monitoring special cable, which combines video coaxial cable, power cable, data cable and steel strand to form a flat ribbon cable, so that the whole strip The tensile force of the cable is tolerated by the steel strand, and the tensile strength is very good. It does not break the signal cable due to gravity during the operation of the elevator.

2, good electrical parameters: in the process of the cable moving up and down with the elevator, there will be a section of the bending deformation caused by gravity, resulting in changes in electrical parameters such as cable impedance and distributed capacitance. When the cable of poor quality is deformed by force, the parameter changes greatly, which will cause impedance mismatch, increase video attenuation and generate signal reflection. This will cause the signal-to-noise ratio of the video signal to decrease and cause video interference. Therefore, it should be selected as much as possible. Shielded, thick cable video cable to prevent interference signals from "invasion."


— — — — — — — — — TSYV Series: Camera with integrated line — — — — — — — —

First, the product introduction:

The TSYV camera uses a comprehensive line, which is mostly used in short-distance multi-transmission systems, and is suitable for close-range monitoring or computer video display system connection and engineering connection lines. The product adopts oxygen-free copper OFC conductor, PE solid insulation and independent shielding structure, which can effectively reduce external interference, ensure high-speed transmission of signals, and ensure clearer display effect. At the same time, 2-core power cable is used with coaxial cable, that is, transmission The signal and power supply do not interfere with each other, and it is convenient for structured integrated wiring.

product description:

SYWV, commonly known as TV antenna, is a kind of coaxial RF cable through physical foaming. 

The physical foaming coaxial cable is an air-insulated coaxial cable, and the inner conductor is made of oxygen-free copper wire, and the insulation is physically foamed by polyethylene to form fine closed pores. The bond between the insulation and the inner conductor is firm.

Such as SYWV75-5

S: RF, Y: Polyethylene insulation, W: Physical foaming, V: PVC sheath

75:75 ohms, 5: cable outer diameter is 5MM, 1: represents a single core

Installation conditions:Operating temperature (°C): -40°C to +65°C

The minimum bending radius is allowed: not less than 5 times the outer diameter of the cable when used indoors, and not less than 10 times the outer diameter of the cable for outdoor use.
