What is an AHD Camera?

The term "AHD camera system" is something you may have bumped into in case you're shopping for a security camera. And what is AHD meaning, and how do these cameras function?

 "AHD" is "analog high-definition" of acronym . It's a new analog video standard and is used as a security video application which is giving much sharper, clearer than the traditional standard analog systems.

Here are the key things to know about AHD camera technology:

• AHD cameras still use coaxial cable like traditional analog cameras. However, they can transmit video over longer distances of up to 500-800 meters without losing quality.
• Resolution supported is improved - most AHD cameras can capture video at 1080p HD resolution which is significantly better than older 480p Analog systems.
• The video looks sharper and has less noise than DVR systems using standard analog. This is thanks to the AHD standard's improved video compression.
• They are generally more affordable than IP security cameras while offering better image quality than standard analog cameras.
• AHD cameras are compatible with existing coaxial cabling but require an AHD-enabled DVR or NVR for recording and viewing footage.

AHD has 3 formats:

AHD08: Image definition between 960H and 720P, max to 800TVL

AHD10: Image definition of AHD is equals to 720P IP camera

AHD20: Image definition up to 1080P

AHD cameras advantages:

An important plus of AHD cameras is that they are able to be used together with the analog CCTV systems. They can be seamlessly incorporated into the existing infrastructures without requiring deep re-wiring or expensive and time-consuming upgrades. Therefore, AHD cameras are utilized as a low-cost alternative for the development of surveillance systems that have HD capability.

AHD cameras also offer other features and benefits, such as:

• Wide Dynamic Range (WDR): The cameras with AHD technology and WDR feature can even capture clearer images in adverse lighting conditions such as those that are backlight with bright spots or have high contrast variations.
• Night Vision: Oftentimes, AHD cameras have the feature of infrared (IR) LEDs installed in them for the purpose of that they can take good quality images even in low-light or even complete dark. This particular characteristic is considered as the very core of surveillance around the clock.
• Remote Access: The HD cameras can be linked either with a network video recorder (NVR) or a digital video recorder (DVR) for remote access and viewing from anywhere using a smartphone, tablet, or computer.
• Motion Detection: AHD cameras are able to be configured such that they will become active whenever they detect motion within their surveillance area. When motion gets detected the camera can show alerts or begin recording then it enhances security and saves from constant surveillance.

• Weather Resistance: In a variety of AHD cameras there are those designed to operate in the outdoors with stable performance in any weather. They are resistance against severe weather, such as rain, hail, and excessively hot or low temperatures.

So in summary - AHD cameras deliver higher quality security video over coax than analog options, making them a cost-effective upgrade for businesses and homes with existing cabling. Their picture quality falls between traditional analog and full IP camera systems.
