If you opt to use a high powered electrically operated door mechanism you will need to provide a
separate power supply to the relay circuit. Alternatively, you could utilise a low powered lock
mechanism, which can be connected via the powered door bell (backlight) with the PoE system, as
there is sufficient power available in this system to accommodate this (please see picture 4).
Picture 1 Motherboard
The connection of relay contact terminals is illustrated on
picture 2
. The “
NO
” annotation means an
idle-disconnected contact, “
COM
” means a pin contact (middle) and “
NC
” means an idle-connected
contact. The contacts of both connectors are galvanic insulated from each other and also from other
circuit contacts.
The alternative connections are shown on
picture 3
and
4
.
The camera can be tilted vertically (up and down) so that the optimal picture can be achieved.
