Detailed explanation of three transmission methods of security video HD video signal

At present, high-definition video signals have three transmission modes: analog, digital, and network. The first two methods are used to transmit lossless, uncompressed analog and digital HD signals.

Analog high-definition signal transmission generally uses YPbPr component transmission, and one high-definition video signal requires three coaxial cables to transmit at the same time, and the cable usage is very large. Although the distance of the component transmission can be extended by the third-party device, since the transmission is an analog signal, the signal is damaged after being transmitted over a long distance. Therefore, YPbPr component transmission is not suitable for HD monitoring.

Digital HD signal transmission is generally transmitted by DVI, HDMI or HD-SDI. The transmission distance of DVI or HDMI is only a few meters, which is not suitable for monitoring transmission. Although HD-SDI can transmit about 100 meters, the requirements for coaxial cable are very high. High, the price of the cable is also very expensive, so it can only be prohibitive for large-scale applications in the system.

Network HD signal transmission, as its name suggests, is to transmit high-definition video signals through network transmission, and often uses a star-structured Ethernet network to realize high-definition network video signal transmission. The transmission distance varies from 100 meters to tens of kilometers depending on the selected line. Compared with the previous analog and digital methods, the transmission cost is relatively low and the performance is stable. It is currently the most widely used in high-definition surveillance systems. A cost-effective transmission method.

Vibration Motor is in the original basis to add a vibrating head, made into a Dc Motor drive with a vibration motor. To produce the shaking force.

6V Dc Vibration Motor is introduced:

6V Dc Vibration Motor volume is generally greater than 15 mm, mainly used in massage chair, massage waist, handheld massager, etc.

Characteristics: small volume, strong vibration;

Features: small size, fast speed, stable performance, low price, can use battery drive,Can change the different materials of the pendulum head
  6V Dc Vibration Motor      6V Dc Vibration Motor
Method of use: the best stable in horizontal plane, installed on the dc 6V Dc Vibration Motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc 6V Dc Vibration Motor drive, may cause damage to internal components, and cannot be used in the case of blocked.

Operating temperature range:

6V Dc Vibration Motor should be used at a temperature of -10~60℃.

The figures stated in the catalog specifications are based on use at  ordinary room temperature catalog specifications re based on use at ordinary room temperature  (approximately20~25℃.

If a vibration motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.

Storage temperature range:

Dc Vibration Motor should be stored ta a temperature of -15~65℃.

In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.

Service life:

The longevity of Dc Vibration Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.

when it come to volume production,we're a major player as well .each month,we rurn out  600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
