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

(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)

(Digital

Input)

Connect to GND to activate, or leave floating (or

unconnected) to deactivate.

Must not be

exposed to

voltages greater

than 30V DC.
