Low price OR high stability SD card to do monitoring storage

How much do you know about SD card? Mobile phone, camera, notebook. . . SD cards can be seen everywhere on these products. Whether they are microSD or standard SD cards, whether they are product-recognition SD cards or SD cards, there are more and more “portable” storage products around us. From the beginning of the M-class units to the current G-class units, and to be mature T-class unit storage, the capacity of the memory card is expanding, the volume is decreasing, in fact, its application areas are constantly expanding.

What is SD card?

The SD card's full spell is Secure Digital, which is a memory card standard. As a memory card, it is widely used on portable devices. As you know, cell phones, digital cameras, etc. As mentioned above, SD card size is different, memory capacity is different, and its read and write speeds are also different. SD card speed specifications, divided into four: Class2, 4, 6, 10, the minimum speed of 2MB / s, 4MB / s, 6MB / s, 10MB / s, your SD card can meet the data read and write speed What?

Multi-domain applications of SD cards

SD Card Multipurpose - Camera

Speaking of the camera, everyone needs to have something to say, but the small series is still talking about the SD card in the camera. Since the popularity of digital cameras, SD card storage has always been accompanied by card machines, micro cards, and single-phase reversals. The current mainstream SD card is an SDHC card, and the maximum storage space can reach 32 GB. However, the SDHC card has a large limitation in the reading speed, and the future will be replaced by SDXC.

Multi-purpose expansion slots for SD cards

Why even the SD card expansion slot has said? Regardless of the product, an expansion slot at the beginning of the design naturally supports the writing of the device. Notebooks, small printers, etc. all have an SD card expansion slot. This is the advantage of the SD card, and it is also a feature that can be applied in many fields.

SD Card Multipurpose - Monitoring Storage

Speaking of the advantages of the SD card, then we must return to the theme of today, whether it can become a home monitoring storage device? First of all, in terms of traditional home monitoring systems, there is simply no SD card expansion slot, let alone its application. Second, DVR supports SD cards. Isn't that a joke? With a monitoring hard drive who also needs a small SD card! However, today's home monitoring has been separated from the traditional security system and has become an integrated monitoring device.

At present, home monitoring products are no longer the usual way. From the store's point of view, most home surveillance cameras support SD cards. The unique SD card expansion slot design supports portable video image storage, taking into account the current storage capacity of the card. Under high-definition monitoring conditions, 24 hours of continuous storage of about 3 ~ 5G, with 32G maximum storage standards, it can easily meet the storage needs of the week. Obviously in terms of data storage, the SD card meets the high-definition storage requirements of home surveillance.

The well-known SD card not only depends on the storage capacity, but more importantly, the read/write speed. Can it meet the storage requirements of video surveillance data? We use a digital camera as an example. Currently, the reading and writing speeds of popular SD cards range from 4 to 10 M. The imaging pixels of digital cameras take 8 million px as an example. The effect of home HD surveillance imaging is naturally not comparable with that of digital cameras. Obviously, it can meet digital requirements. The camera's storage speed naturally meets the monitoring image data.

After talking about the function, I finally talked about the price. This is where civilian security is most concerned. I see from the electronic mall, a 16G SD card prices ranging from 60 to 100 yuan, the price fluctuation and memory card read and write speed naturally related. Obviously, such a small card, home users can still afford it.

A home surveillance camera that supports SD card currently has a market price of around 2,300 yuan. It is equipped with a single point of control and integrates monitoring, alarm, and voice dialogue. This integrated home surveillance camera does not require the wiring of an engineering firm, and network monitoring supports mobile and remote monitoring. View and dispatch, from monitoring equipment to storage equipment, the price of the entire monitoring system is less than 2,500 yuan. The traditional home surveillance cameras, high-definition monitoring probe price of 500 yuan, with a set of alarm systems, including detectors, alarm host prices will be 300 yuan; also as a monitoring storage device, DVR + monitor hard drive prices approaching 1,000 yuan, In addition, including wiring, video lines and labor costs, etc., also close to 2,000 yuan, and at this time to achieve two-way intercom, I am afraid the price will be higher.

Of course, for home monitoring, if the cost is quite the same, whether to meet the multi-functional needs or to meet the long-term storage needs depends on the user's own needs. However, understanding multi-party analysis, SD card as a monitoring storage device seems to be a good choice.

In fact, with the current home monitoring storage, home monitoring systems supporting SD card storage are gradually becoming mainstream. Integrated monitoring equipment, from video surveillance to video storage, ranging from monitoring to alarm; 3G and WIFI network monitoring products eliminate the need for wiring, and relatively integrated monitoring equipment also allows consumers to save the maintenance of multiple parts What are the disadvantages? Does your home have a monitoring system installed? Did your monitoring system save money and worry.
