Alarm Wiring Diagram
This document details a specific layout of alarm wiring inputs and outputs.
I/O (Input/Output) Ports
The input/output ports provide the following:
- Alarm input/output
- Audio input/output
The pin assignment for the audio I/O and the alarm I/O is the following:
| Pin number | Signal |
|---|---|
| 1 | Alarm output |
| 2 | GND |
| 3 | Alarm input |
| 4 | GND |
| 5 | Audio input |
| 6 | Audio output |
Wiring Diagram for Alarm Input
The following diagram demonstrates how the device triggers alarm input through the external mechanical switch or through the external open collector circuit.
Diagram Description: The alarm input diagram illustrates how an external mechanical switch or an open collector output device can trigger the alarm input on the camera. On the 'Outside' side, a mechanical switch or an open collector output device is connected in series with a 1000pF capacitor. This combination is then connected to the camera's alarm input pin (Pin 3) and ground (Pin 2 or 4). The circuit includes a 2.2K ohm resistor connected between the alarm input and ground, and a 1000pF capacitor and a 22K ohm resistor in parallel, connected from the alarm input to a 3.3V source. A 5V source is also indicated, along with a 1.69K ohm resistor and a 0.1uF capacitor, suggesting a more complex input conditioning circuit or reference voltage.
Wiring Diagram for Alarm Output
The following diagram demonstrates an example of how the device can provide the alarm output function. This alarm output function outputs a connection to ground for external devices.
Diagram Description: The alarm output diagram shows how the camera can provide an alarm output signal to external devices. On the 'Camera side', a MOSFET is used as a switch. The gate (G) of the MOSFET is controlled by the camera's internal logic. The drain (D) is connected through a 1K ohm resistor and a 1000pF capacitor to the camera's internal circuitry. The source (S) of the MOSFET is connected to ground. On the 'Outside' side, the alarm output is connected to the drain of the MOSFET. This connection allows the camera to pull the output line to ground when an alarm condition is active. The circuit is designed to drive external devices with a maximum of 12V. A resistor (R) and an LED are shown in series, connected between the 12V maximum source and the output line, indicating a possible indicator light or load for the output.
