To purchase a good video matrix switching system engineering program, it is necessary to consider that construction and maintenance costs should be reduced as much as possible to avoid premature equipment elimination, and we should also have a good understanding of today’s new technologies and select advanced technologies that meet the requirements. product.
1. Chinese interface and pinyin input method are the most basic requirements
To enter the Chinese market, any product must first have a Chinese version of the software; second, the Chinese character input method can not be ignored. Simple and practical is the key to the Chinese character input method. It should be as close as possible to the well-known and universal Chinese character input method. For example, Pinyin input method is a good choice; Thirdly, Chinese data and Chinese manuals are familiar and well-used. Equipment prerequisites. If the information is in foreign languages, it is hard to say that the project owner and users will read and understand it carefully and comprehensively.
2. Distinguish the merits of the product from the use and installation manual
Good products must have good user manuals and installation manuals. How to determine the quality of the manual? The simple method is to look at the print quality and the thickness of the manual. If you look carefully, you can also see whether it can solve the problems encountered during use. In general, a thick user manual means that the product has better functions and the company’s technical strength is stronger.
3. See the construction and maintenance of the project from the connection mode of the product
The video matrix system needs to connect a large number of cables. These cables include coaxial cables that connect video signals, shielded cables that connect audio signals, control lines that connect sub-control keyboards, twisted-pair cables that connect to PTZ cameras, and pairs that connect alarm signals. Stranded cables, etc. These cables all require connectors to be connected to the system. When purchasing products, products that require welding should be avoided as much as possible. Welding is not only laborious but also is not conducive to on-site maintenance.
4. Use a system that has an internal dome camera
If you plan to use a high-speed dome camera in your engineering design, you should confirm that the optional control system fully supports these functions. Some systems are unable to control the dome camera anyway, some require expensive conversion interfaces, and some have direct control of commonly used dome cameras. The dome camera generally has a preset point function. Therefore, it is also required to confirm whether the selected system supports the camera preset point function and whether the preset point identification address can be set.
5. Confirm how fault-tolerant the system is
Users will inevitably make mistakes during use. Therefore, the fault tolerance of the system is particularly important. Some products have caused a lot of trouble due to software design problems. For example, some systems cannot work at all after inputting incorrect data or strong interference. All data previously set must be cleared and reset. This is very important for users. Painful and disastrous.
6. Character superposition is an important part of system cost
Of course, security products should all have the function of character superposition. Otherwise, it is impossible to distinguish between images and the current working state of the system. In terms of character display, some can only display English, some can be displayed in English or Chinese, some have borders, and some have no borders. It is best to have a system that can display Chinese and English with borders. Whether or not the character display and display mode is a major factor affecting the price of the product, and some product offers are based on no character display. Therefore, this should be fully taken into account when comparing product prices.
7. Reject all products that have the "millennium bug" problem
Security should not only have timeliness, but also have a long duration, that is, the information it records should be traceable. The picture seen on the monitor is an ongoing crime, and the scene recorded by the video recorder should be able to be used for retrieval and analysis after the incident. If, after 2003, the judiciary reanalyzes the video of the crime scene with the date recorded on the screen as "01-02-03," it will not be able to confirm which month of which year and which day the crime occurred.
