It is a new generation multiple biometric identification product, standard integrating with Face, Fingerprint, PIN recognition and optional with RFID mode, as to facial identification algorithm, it captures the relative position, size, and shape of user's eyes, nose, cheekbones, and jaw features, these feature templates are used to be matching feature data, when users verify on device, it distills captured features into value and compares with templates to eliminate variance. It may hold 400 faces without dividing groups, its default identification mode is Fingerprint & Face, additionally, as it is a kind of professional access control facial device, it may work with the third party such as electric lock, alarm, door belling, sensor and so on, in order to improve security for human life and enterprise information.

What is the use of Intel 8257 microprocessor?
Its a Programmable Direct Memory Access (DMA) controller.
List of typical Direct memory access channel?
list of typical direct memory channel
With the memory controller can communicate with two DIMMs at the same time effectively doubling the speed of memory access?
dual channels
What does DMA stand for and what does it do?
DMA, Direct Memory Access, is a method of transferring data from the computer's RAM to another part of the computer without processing it using the CPU.
What does the appreviation UDMA stand for?
The abbreviation UDMA stands for Ultra Direct Memory Access. The Ultra Direct Memory Access is a mass storage interface and is common in computers and other electronic devices.
What resource is allows a hardware device to directly access RAM?
direct memory access (DMA)
Difference between direct and sequential access?
RAM or Random Access Memory is used for fast computer memory. The word "Random" is a bit of a misnomer, as there is nothing random about access to this memory. What it actually means is that you can select an address at "random", that is, any address within the capability of the memory, and read or write data to/from that address just as fast as you could read or write data to any other address. In other words, data stored anywhere in the memory can be accessed quickly. Serial memory is different in that access time depends upon where on the medium the data is stored. Examples are magnetic tape, optical disk, magnetic disk. "arbitary access" is not a term used in electronics that I can find. I think it is just another term for "random access".
What is the meaning of dma in tellabs 8110 modem?
direct memory access
What technique is used to transfer data directly from the hard disk to memory?
DMA - Direct Memory Access
What technique is used to transfer data directly from the hard disk to memory.?
DMA - Direct Memory Access
Why Direct memory access has priority over the CPU when both request a memory transfer?
we can transfer data direct to and from memory without the need of the CPU. The transfer of data between a fast storage device such as magnetic disk and memory is often limited by the speed of the CPU. Removing the CPU from the path and letting the peripheral device manager the memory buses directly would improve the speed of transfer. This transfer technique is called direct memory access(DMA). During DMA transfer, the CPU is idle and has no control of the memory buses. A DMA controller takes over the buses to manage the transfer directly between the I/O device and memory. With Regards.
