What are the classifications of storage devices in security monitoring systems? We generally talk about it from four aspects.
1. Generally, a monitoring system is installed. The required links can be roughly divided into three aspects: camera, DVR, and display device. Among them, among the DVRs, there are hard disk DVRs and SD card DVRs. The most basic two are very different in size, weight and storage capacity; another important thing is that the maintenance and shock resistance requirements of the hard disk DVR are relatively higher than the SD card. At present, the SD card series DVR is developing rapidly, and it is becoming more and more popular as a new type of security monitoring DVR. Keeping up with the market, like our company has launched a series of SD card DVRs to meet the needs of home security.
2. Generally, in the home security monitoring, if you use SD card storage, how long can you save? In fact, how long it takes to save, there are many factors to consider. Not only the specific image color, but also the storage format and storage media capacity. At present, there are many kinds of SD storage capacity on the market: as small as 1G or 2G, as large as 32G. Like our company, the largest 32G (DVR9088) and 16G (DVR8600) are currently available, at least 2G (DVR8100). Choose the right product for your application and needs.
3. In security monitoring, in addition to the video function, what other functions? The functions are simple and complex depending on the product. Generally, the hard disk DVR does more functions, and the function of the SD card is simple and easy to operate. But what kind of environment should choose practical functions. Generally used in home security, the customer is the majority of residents, easy to operate and easy to win customers. Our company has launched a series of DVRs for SD card storage around the market. In addition to manual function recording, it also provides external triggering, motion detection and video recording, and an external alarm device to output alarm signals. At the same time, each parameter provides menu settings.
4. What are the differences between analog and digital devices in ac monitoring? The SD card DVR has analog and digital distinctions, and both are widely used. The analog DVR input and output are analog signals. In the installation, the external analog camera is convenient, and it is widely used in most applications. Customers can connect external analog cameras either wired or wireless as needed.
