In this article, we are going to answer all these questions in simple and practical language.

🔍 What is an AHD camera?

AHD stands for Analog High Definition, which means high-quality analog. These types of cameras are capable of recording HD or even Full HD quality images, while still using an analog signal to transmit the image.

✅ AHD camera features:

Higher image quality than traditional analog cameras

Requires a special DVR (AHD DVR)

No remote access without advanced settings

Suitable for environments with limited budgets but requiring better quality

⚙️ How does an AHD camera work?

An AHD camera uses digital sensors to record images, but before sending them to the DVR, it converts the image to an analog HD format. This format is designed to transmit high quality over old RG59 and BNC cables.

💡 AHD camera working steps:

Image capture: The camera records the image with a digital lens and sensor.

Conversion to AHD signal: The digital image is converted to an analog HD format.

Transfer to DVR: Transferred to DVR via RG59 cable and BNC connection.

Storage and viewing: The DVR stores images and allows live viewing or playback.
