AHD Explained

The world of surveillance cameras is vast and diverse, with numerous options available to suit different needs and situations. One such option is AHD CCTV, which stands for “analog high definition.” AHD has emerged as a new HD surveillance video standard for CCTV cameras and DVRs, offering exceptional image quality and versatility.

Understanding AHD CCTV

AHD technology currently supports High Definition 720p, 1080p, and even 4MP, 5MP, and 8MP resolutions. This means that AHD cameras provide crystal-clear footage, allowing you to capture every important detail with precision and clarity.

When considering which camera is best suited for your specific requirements, it’s essential to evaluate several factors. These include the distance from the camera to the desired field of view, the width of the field of view, and the lighting conditions in the area. Additionally, you need to determine whether you need color or black and white footage, as each has its own advantages in different lighting situations.

A Deeper Dive into AHD Technology

AHD CCTV is an analog high-definition closed-circuit television video surveillance standard that utilizes coaxial cables to transmit HD video from security cameras to DVRs. This technology supports resolutions ranging from 720p to 8MP, ensuring exceptional image quality for your surveillance needs.

To better understand the different technologies available, let’s briefly explore the various options:

• Analog: This technology offers up to 1000 TVL (Television Lines).
• AHD: Analog High Definition represents the pinnacle of analog surveillance, providing resolutions up to 8MP.
• CVI/TVI: These technologies differ among manufacturers, offering their unique features.
• SDI: Full High Definition at 1080p resolution.
• IP: Network/Digital cameras that utilize network connections for video transmission.

The Benefits of AHD Cameras

AHD CCTV cameras offer numerous advantages, making them an excellent choice for your surveillance needs. These benefits include:

1. High Definition Resolution: AHD cameras can capture video surveillance at up to 8MP resolution, ensuring outstanding image quality.
2. Plug and Play Installation: AHD cameras work seamlessly with AHD DVRs, simplifying the installation process.
3. Convenience: The cameras and DVRs are connected through BNC (Bayonet Neill-Concelman) cables, providing power and transferring video feed for recording, video management, and alarm functionalities.

Addressing Common Questions

To further enhance your understanding, let’s address some common questions regarding AHD cameras:

Q: What type of cables are used for AHD camera installations?

AHD cameras are typically installed using coaxial cables, providing a reliable and efficient means of transmission.

Q: What is CMOS?

CMOS is an abbreviation for Complementary Metal-Oxide Semiconductor, which refers to the image sensor in cameras. It converts light into electrons, capturing the visual information you see on screen.

Q: What are the different lens categories used in AHD cameras?

AHD cameras mainly feature two lens categories: fixed and varifocal lenses. Fixed lenses with various focal lengths, such as 2.6mm, 3.6mm, 6mm, 8mm, and 12mm, are selected based on specific requirements.

Q: What is the function of an ICR or IR cut filter?

An ICR (IR-Cut Filter Removable) is a mechanical shutter placed between the lens and the image sensor, controlling the passage of infrared light. When enabled, the ICR blocks infrared light, allowing only visible light to pass through. When disabled, the camera captures black and white images, which are more sensitive to infrared light.

Q: What are IR LEDs, and how do they enhance AHD cameras?

IR LEDs (Infrared Light Emitting Diodes) are solid-state lighting devices that emit infrared light. They are used to enhance visibility in low-light conditions. IR LEDs enable AHD cameras to capture footage discreetly, acting as a spotlight while remaining invisible to the naked eye.
