Do not plug into the same hub with the previous generation DPC-D211 (without the "S" label). Communication is only one-channel. The system intelligently switches between the doorman and the monitor. The problem can arise in noisy areas such as kindergartens, or near noisy roads. For use in nurseries, we recommend using a monitor with a handset or a Dahua IP system.

Activation of switching: for 1 second to 10 minutes depending on the setting
Video: 1Vp-p 75 ohm CCIR
Connection of the exit button to open the lock: 2-pole terminal block
Properties:
- at most one call on the bus at a time
- calls from the door station take precedence over intercoms
- a call from the door station blocks uncalled monitors from activity, signaled by an LED (buses)
- if the called station is already talking, a warning tone will sound when you press the button on the doorbell and the backlight of the called station will not flash
- direct dialing participant by button
- infrared illuminator for night vision
- expansion of the number of buttons modules
- speaker
- stainless cover
- direct lock control, NC/NO contacts, 12 V DC
- the possibility of directly setting the lock type (NO/NC), opening time, warning tone volume, communication volume
- adjustable max. ringing time (standard 30 s, range 10-600 s)
- adjustable max. conversation time from the door station (standard 60 s, range 6-600 s)
- adjustable max. intercom conversation time (standard 60 s)
Installation
- Phone addressing by DIP switches.
Door Station Camera Previews:
- the door station allows you to preview the camera of any of the connected house phones from the monitor
- preview switches between house phones automatically every 15 seconds (adjustable in the range of 6-600 s)
- it is possible to enable it to be able to talk on the phone while previewing
- it is possible to enable the door lock to be unlocked when previewing
Software programming:
Using the SD card, the calling scheme can be modified, including the assignment of the BDU branch.
The system is not suitable for very busy places where there are several door stations in one D2 system. If multiple people repeatedly ring multiple door stations at the same time, the system may freeze. The problem is not, for example, with ordinary apartment buildings with two entrances, but kindergartens are particularly problematic.
