Caddx Gazer Quick Start Guide

Product Introduction

The Caddx Gazer is a full-color night vision analog camera with the following key features:

• Ultra-Low Light Full-Color Night Vision: Provides color images even in extremely dark environments.
• Detachable Filter: Can be removed or attached to preserve daytime image quality and enhance nighttime brightness, suitable for all-weather use.
• AI Image Enhancement: Offers clear details during the day and AI enhancement at night for maintained clarity and high color reproduction.
• Adjustable Zoom Function: Supports 3x magnification with stable image quality.

Installation Direction

Ensure the camera is installed with this side facing upwards to prevent upside-down images.

Control Mode

The Caddx Gazer can be controlled via a flight controller (FC) for zoom and day/night mode switching.

Zoom Function:

Set one FC solder pad to output a PWM signal for control. The FC outputs a PWM signal to perform zoom operations. For example:

• 100% duty cycle: 1x zoom
• 200% duty cycle: 2x zoom

Reset Function:

Set one FC solder pad with a TX-defined IO to trigger the switch. This allows direct switching from high magnification to 1x and restores zoom focus when turned off.

Reset Function (Day/Night Mode Switch):

Set one FC solder pad with a TX-defined IO to trigger the day/night mode switch. Day mode requires the filter, while night mode does not.

Connection

Power / CVBS Connection:

• POWER: FC solder pad, 9-24V
• GND: Connect to GND
• CVBS: Connect to the FC CAM interface

Debugging Procedure

The following is an example of control line soldering and Betaflight configuration. Other solder pad definitions can be configured as needed.

Control Line Soldering Example:

• 2A7: Connect to flight controller TX1
• 2A8: Connect to flight controller M7
• 2A5: Connect to flight controller TX6
• GND: Connect to GND

In the Betaflight program, select the "CLI" option. Enter commands to view pin definitions.

RC Channel Configuration:

In Betaflight, navigate to the "Modes" option.

1. Find "USER1", enable it, and set the switch to "AUX 4" if Channel 4 is a 2-position switch.
2. Find "USER2", enable it, and set the switch to "AUX 5" if Channel 5 is a 2-position switch.
