Situations when it is necessary to find out what is happening in the home or in the office during our absence arise in modern life much more often than we would like. And it does not matter at all whether it is a babysitter or a nurse, or whether teenage children left on the farm are to be monitored, the real result will be a video surveillance only if it is invisible. For the house, the ideal way to implement such video surveillance is to install a portable wireless camera with a recording on a USB flash drive.
Advantages of cameras with a record on the USB flash drive
So, what are so good cameras with video recording on the USB flash drive? First, the fact that for their installation do not need any special skills or knowledge. It is enough just to insert a flash memory card into the special slot and connect the camera to the mains, and then activate the recording process according to the instruction. Secondly, small size, which makes it possible to install such a camera absolutely imperceptibly for others. Thirdly, a fairly large amount of memory. Depending on the volume of the flash drive and the degree of video compression, such a camera will be able to record events 3-5 days in a row. Especially convenient is that when all memory is full, the record will not be interrupted, but will simply start to displace the earliest files. Thus, the camera will operate until it is powered. Fourth, can not but rejoice the availability of components. Recording in such cameras is conducted on standard memory cards (micro SD, micro MMC), which can be purchased at any electronics store. The only disadvantage of such cameras is that in case of detection of video surveillance, an attacker without special efforts will be able to take out and irretrievably destroy flash memory with the data available on it.
CCTV camera with recording on a USB flash drive - the features of choice
Among the cameras that have the ability to not only record what is happening, but also record it on a removable flash memory, you can find both very simple models and super-heaped copies. Additional functions, such as motion sensor, infrared illumination or the ability to transfer data from the camera via the Internet, not only make the use of the camera more convenient, but also significantly "increase" its cost. On average, the cost of the camera with the recording function starts from the mark of $ 70.
