Interface Description
LABEL NO. INTERFACE DESCRIPTION
10 Y (CVBS) Y in component video mode and CVBS in composite
video mode.
11 Pb Pb in component video mode.
12 Pr Pr in component video mode.
13 SD Card Slot For inserting the SD card to store data directly in to the card.
14 User Input
Button Boots the camera with default IP configuration. Keep it
pressed for 15 seconds during power on (Sts. LED blinks
amber) and then release it.
15 I/O Connects an external alarm event detector to input port
and an activation port from output port.
GND
Digital ground is used as return path for 3.3V supply
pin and reference GND for IN and OUT ports.
IN Active: Input pin is connected to GND.
Inactive: Pin is open or unconnected.
OUT Uses an open-collector transistor with the emitter
connected to GND.
When the port is activated, it gets connected
to GND through the transistor. The sink current
through the port should not exceed 150 mA and
maximum voltage the port can be exposed to is
24 V DC.
i
Note : If used with an external inductive
load like relay, appropriate free-wheeling diode
should be used across the inductive load to avoid
damage to transistor due to surges.
3.3V Powers auxiliary equipment. Maximum current it
can supply is 200 mA. Drawing more current can
damage the camera.
