Video Optical Specifications Multiple digital video optical transceivers can have multiple functions. Each type of function has corresponding technical specifications, such as video indicators, audio indicators, asynchronous data indicators, Ethernet indicators, and so on. Here, from the perspective of monitoring engineering, we will focus on the following two video indicators.
Is the video bandwidth enough?
Is the APL range wide enough?
Reliability considerations. As a security monitoring project, equipment reliability should be the first consideration. The reliability of the equipment is the equipment manufacturer must consider when designing the product, however, some manufacturers may be unwilling to do or do not know how to do this work for some reasons. The reliability of the product can be roughly examined from the following points.
Is the power supply convenient and the power range name is not wide enough?
The adaptability of temperature and humidity is not strong enough.
Optical port protection measures are in place.
Grounding considerations, in the security monitoring project, ensuring the equipment is well grounded is an important part of ensuring equipment reliability. A good grounding will benefit the equipment against surge surge, anti-static and lightning strikes, which can significantly increase the reliability of the equipment.
Video optical transceivers are practical considerations. Each vendor should provide mature products to users and contractors, not research prototypes. Therefore, it must have practical considerations. When selecting a video optical transceiver, users and engineers can consider more from the perspective of the practicality of the device. First, practical issues are easily judged by users and contractors. Second, it is difficult to believe that manufacturers who can't do a good job can do a good job in the reliability and technical indicators of optical transceivers. The practicality of the product can usually be examined from the following perspectives.
The appearance is generous and the structure is reasonable.
The interface is rich and the layout is reasonable.
The meaning of the indicator light is clear, which facilitates the opening and maintenance of the project.
Video can be up and down, networking is convenient.
In short, the user should consider and compare the video optical transceiver 's technical indicators, reliability, practicability and pertinence when selecting the equipment. According to the actual situation of their own projects to do a suitable program, and finally you can find a suitable video optical transceiver.
