01. RF sensor technology and digital camera technology, to support ID cards and IC card (factory built-ID sensor reader), reader from the 5-10CM. 
 02. Can store two hundred thousand pen punch card records, photographs and about twenty thousand thousand pieces of video images (at 320 × 240 resolution), limited the number of attendance. When the memory is full, the first image is removed, the picture used compression, so the complexity of the picture size will affect the compression, the image size is a single background pattern prevail. 
 03. When set to access attendance, you can send the card number 2000, in the file does not exist when the card punch machine blew attendance, suggesting that illegal, otherwise the normal prompt and display the corresponding job number (job number and card number can be different), optional remote control receiver module, to start the electromagnetic locks. (Simultaneous start 2.) 04.U rapid acquisition offer: full-time played, collecting only about 10 minutes, attendance records collected only tens of seconds. U-disk can only set the acquisition, which prevents malicious attendance data collection. 
 05. In the alarm period, when the attendance to the image change detection and send remote control signals and sounding the alarm, while every 3 seconds for video, when the image does not change the set "alarm bell number of minutes" after the end Attendance issued by the end of the alarm remote control signal, but the attendance to keep sounding until the alarm sensors to alert occurred. 320 * 240 resolution video to record. Optional remote control receiver module, the alarm bell to start the device. 06. With intelligent video control: recording interval can be set to 3-60 seconds, and only when the images change significantly after the records, which can greatly extend the recording time, video can be set to 240 or 160 * 320 * 120. 
 07. Clock can be set when the "stable image shooting," that is shaking the image when there is no obvious can punch, which can prevent blurred photos due to shaking. 08. Attendance machine with battery, sustainable work after power outage (sustainable work 4 hours), power-down data in permanent storage. 
 09. Attendance intelligent shutdown, power off and switch to avoid causing data corruption. 10. With a remote access control, alarm function, built-in wireless transmitter module, in the case of non-interference and obstacles, the effective distance of 5-10 m 
 11. Attendance software with fast matching function, in a few seconds time comparable to the hundreds of photos, you can quickly determine the replacement card.
