Frequently Asked Questions - CV226 MARSHALL

How do I reset the camera to factory default?

To reset to factory default, push the OSD joystick UP, DOWN, UP, DOWN, then PUSH and HOLD for five seconds. The camera will reset to 1920x1080p @ 30fps. If it doesn't reset, power-cycle the camera and repeat.

What should I do if there is nothing on the screen?

Check that all connected devices are powered on, confirm the voltage and current from the power supply are correct, and verify that all video cables are properly connected.

How can I improve picture clarity?

Ensure the monitor is adjusted correctly, clean the lens glass with a soft, dry, non-abrasive cloth or lens cleaning set, and properly adjust the focus.

Why is the picture flickering?

Check termination and set impedance to 75Ω properly. Ensure the camera is not pointing directly at the sun or a light source. Verify intermediate devices and cable length do not exceed the maximum transfer limit.

How do I adjust white balance?

In the OSD menu, select WB CONTROL. Choose AUTO (3000-8000°K), ATW (1900-11000°K continuous adjustment), PUSH (place white paper in front and press OSD), or MANUAL to fine-tune color temperature, red gain, and blue gain.

What is the maximum frame rate and resolution?

The camera supports up to 1920x1080p at 60fps. Other resolutions include 720p and 1080i at various frame rates.

Can I use the camera in harsh weather?

Yes, the CV226 has an IP67-rated all-weather body, making it suitable for outdoor use.

How do I change the lens?

Remove the IP67-rated cap by rotating it counter-clockwise. The M12 lens can then be unscrewed and replaced with another M12 lens of a different focal length.

What does the IMAGE STABILIZER do?

It reduces image blur caused by vibration. You can set the digital zoom range (up to 30%), filter level, and auto-centering for severe or minor vibration.

How do I set a camera ID?

In the DISPLAY CONTROL menu, select CAM ID and adjust from 0 to 255 using the OSD joystick.
