Introduction
Handsfree Video Doorphone
The DOSS DHF52PC provides audio/visual communication between the indoor monitor and the
outdoor camera. The DHF52PC is an easy to install and inexpensive video intercom system.
Now you can communicate with whoever is at the door without having to open it!
The DHF52PC has a 5” TFT-LCD colour monitor with a simple one button control. Visitors
press the doorbell on the camera and the monitor will ring to let you know someone is at the
door. Their image appears immediately on the monitor and you can speak with them with the
touch of a button. The intercom camera can even see people in the dark. Control the bell volume
and the screen brightness to your liking with easy knob controls located on the monitor.
You can now conveniently identify visitors before answering your door with the intercom
system. This system will increase your home or business security.
Applications & Benets:
Immediately increase the overall security of your home or business, keep annoying solicitors
away, children won’t have to open the door to strangers while you are away, decrease vandalism,
deter potential crime, you don’t have to get up to answer the door, unlock the door remotely for
guests (optional).
Calling:
Visitors press the CALL button on camera unit, the visual image of the visitor appears on the
monitor inside with a electrical doorbell chime sound.
Conversation:
After identifying the visitor visually, talk to the visitor shown on the screen by pressing the
CALL/ MONITOR button and have a conversation just as you would on a normal speaker phone
(hands-free operation).
Monitoring:
Simply press the MONITOR button to identify visitors at the door without them being aware that
they are being watched or to monitor the immediate area around the doorway. This allows you to
monitor the visitors at your door, even though they may not have pressed the call button. This can
help to avoid the risk of opening the door to strangers or to observe the area if you suspect foul
play.
