TCM-7411 Hardware User’s Manual
This camera provides:
•
1 transistor output
- For connecting external devices such as relays and LEDs. Connected
devices can be activated by Output buttons on the Live View page or through video management
software.
•
1 Digital Input
- An alarm input for connecting devices that can toggle between an open and
closed circuit, for example: PIRs, door/window contacts, glass break detectors, etc. The device will
detect the change in digital input and transmit the signal to video surveillance servers.
Terminal Pin Define is described as below:
Pin Name
Description
Spec
DIO PW
Electrically connected in parallel with the con-
nector for the power supply, this pin provides an
auxiliary connector for mains power to the unit.
This pin can also be used to power auxiliary
equipment, with a maximum current of 100mA.
Voltage: 12V DC,
Max: 1.2W
DIO GND
Ground
DO
(Transistor
Output)
Uses an open-collector NPN transistor with the
emitter connected to the GND pin. If used with an
external relay, a diode must be connected in
parallel with the load, for protection against
transient voltages.
Max load = <100mA
Max voltage = 24V
DC (to the
transistor)
DI
(Digital
Input)
Connect to GND to activate, or leave floating (or
unconnected) to deactivate.
Must not be
exposed to
voltages greater
than 30V DC.
