Device enables gate remote control (car entry) using relay1, relay2 and contact
sensor. In this mode, relay1 opens the gate and relay2 closes the gate. There are
two ways of control. It is possible to open and close the gate (switch on relay1 or
relay2) using radio remote control in band 433 or 868 MHz with 4 programmable
pushbuttons (if GSM door entry phone station is embedded with radio interface).
Another option is to open the gate by calling from preset mobile phone. Gate can be
closed (relay2 is switched on) after connection of external infrared sensor to device
sensor which is used to detect the car passing through the gate. Gate can be closed
automatically also when radio remote control is used.
3.3 Attendance evidence
Device can be also used as attendance system. It is possible to set the codes,
contactless cards or mobile phones whose attendance must be recorded. Then, after
identification, system waits for pressing the appropriate attendance type pushbutton.
Pushbuttons have multiple functions. Its meaning depends on the state when the
pushbutton is pressed.
For attendance evidence, following meaning of pushbuttons can be programmed:
0 - attendance departure
1 - attendance arrival
2 - interruption departure
3 - interruption arrival
4 - business departure
5 - business arrival
6 - doctor departure
7 - doctor arrival
or other customer codes (total number of types is max. 12).
Only after pressing the pushbutton, if it is programmed as arrival, the particular relay
is switched on and door is opened. Each code, contactless card and mobile phone
number has the employee registration number set. This number together with
attendance type, date and time, is sent via radio interface and radio / Ethernet
converter to server where the data is saved and processed. Resulting from this,
attendance evidence for one employee can be carried out in several ways.
Special application software on server is necessary for function of receive and save
the attendance data. Attendance evidence and door opening can be performed also
using the radio remote control with 4 programmable pushbuttons of attendance type.
It is the most speed way. The door is opened and no next pushbuttons need to be
pressed.
3.4 Persons control
If device is equipped with integrated color camera, then it is possible to control the
visitors at the door entrance by sending the static images in JPEG format over radio
interface and external radio/Ethernet converter to server. To display the images on
PC or mobile phone, special application software must be used. After pressing the
pushbutton, illumination leds are activated and image transfer starts. Transfer is
stopped if person starts to enter the code. Voice call is delayed, device waits the
