V-500-4-0C is a high quality and stand-alone access control/time attendance system. By using the build- EM card to check the identification, it makes possible to provide reliable security services, thus realizing the automatized, modern, and professional access control/time attendance management. On access control and time attendance, V-500-X-0C provides card only mode. On function , the reading distance for EM card can reach 10~15cm. With the external Wiegand reader, the unit can realize the single-door bi-directional operation. With external fittings via the I/O interface of the unit, the user can connect the exit button, and door contact sensor, and other TTL output devices to open the door, which will send the alarm signal automatically when the unregistered card is reading.

On management, with the build-in LED, V-500-4-0C can manage the system by the configuration card; it can also communicate with the computer via RS232/RS485 to manage and operate the system, and send all the operation records and the status of other devices in real time to the computer, so as to process and print access control records and time attendance tables by the management software.

V-500-4-1C is a high quality and stand-alone access control/time attendance system. The build-in EM card to check the identification makes it possible to provide reliable security device, thus realizing the automatized, modern, and professional access control/time attendance management. On access control and time attendance , V-500-4-1C provides three kinds of operation mode, the most convenient card only mode, the most accurate card + 4 digit PIN mode, and the simplest 4 digit PIN only mode. On function , the reading distance for EM card 15 cm for (depending on the operating environment of the reader and transponders). User-defined 2-digit duress alarm password can be input by the user under duress and the unit can send the signal of help silently by the connected alarm system. With the external Wiegand reader, the unit can realize the single-door bi-directional operation, and enable Anti-pass Back function.

With external fittings via the I/O interface of the unit, the user can connect the exit button, and door contact sensor, and other TTL output devices to open the door, which will send the alarm signal automatically when the unregistered card is reading. On management, with the build-in LED and backlighting keyboard, V-500-4-1C can manage the system by the configuration card or configuration PIN; it can also communicate with the computer via RS232/RS485 to manage and operate the system, and send all the operation records and the status of other devices in real time to the computer, so as to process and print access control records and time attendance tables by the management software.

The user-friendly interface, the 16 x 2 characters LCD with backlight, and 3 x 4 keypad with backlight enable system will be suitable for dark occasion; Beeper’s output, will help to indicator status of user’s operating. Under normal condition, the build-in RS232 interface support readers communicate with Host PC, it made data manages and analysis becomes convenient to user. System could work together with other control system through network connection to achieve complex access control and management; the build-in Flash memory enable system to record event in standalone mode, those data could be used in future.
