CCTV AHD Cameras – Upgrade Your System With AHD

AHD is a new technology that allows you to upgrade your system with HD video. AHD cameras use the same coax cable as traditional analog CCTV systems and can transmit up to 500 meters of high definition video. You can also use UTP network cable with special cables called baluns to get even further distances.

High Definition

HD CCTV cameras are a simple way to upgrade existing analog systems to high definition without major changes. They provide nearly seven times the resolution of traditional 960H systems with progressive-scan digital analogue video. They use the same wiring regulation as 960H and are able to transmit data over the same coaxial cable, providing significant cost savings for system owners. Many of these cameras have a wide range of features, including day/night vision, motion detection, and remote access through a DVR or web browser. Some have a fixed or varifocal lens and can be integrated with existing closed-circuit systems.

Developed by Nextchip, the company that also makes chips for other manufacturers like Dahua and Hanwha Techwin, AHD technology provides 720p and 1080p resolution over existing coaxial cables. Its uncompressed transmission allows more data to be sent over the same cable, making it more reliable and affordable than either HD-SDI or network IP cameras. AHD cameras also include a UTC chip that allows you to control the camera’s internal options directly from your DVR through the video cable, saving you additional cabling.

Wide Dynamic Range

Depending on your business, you might need to monitor areas with variations in lighting or reflections. These are common issues that affect many CCTV cameras and result in poor image quality. A wide dynamic range camera can help to overcome this by compensating for bright and dark parts of the scene to deliver a crisp snapshot or video.

A WDR camera is especially useful for businesses situated near ATMs, which often have reflective screens and can be targeted by thieves or fraudsters. The WDR feature allows you to monitor these areas and ensure the highest quality footage is captured when criminal activity occurs.

There are a couple of different types of wide dynamic range (WDR) technology: True and Digital. The former uses different shutter speeds & raw image processing to balance the brightness of the lightest and darkest parts of the scene. The latter uses clever software to lighten dark areas and sharpen the overall image. This type of technology is best for businesses that require a high level of detail, such as offices and parking lots.

Infrared Night Vision

For the darkest areas of your home or business, look for night vision security cameras that emit invisible infrared light to illuminate their surroundings without drawing attention. This function is especially useful for monitoring your storefront or your front or backyard at night when ahd security camera most people are away or asleep, and it can be a deterrent to criminals because they know you’re watching.

Depending on the model you select, it may have one or multiple infrared LED lights with a certain illumination distance. Look for these specifications on the camera’s specification sheet, or test it out to make sure it can detect and illuminate objects in complete darkness.

Another feature that improves the quality of your video footage is 3D DNR, which reduces the image noise by analyzing frames from the same scene to remove background noise and sharpen details. This is an excellent option for environments with limited ambient light, as it produces a more clear and crisp image than standard noise reduction methods that only analyze a single frame. It’s also an ideal choice for use in surveillance rooms, as it’s less sensitive to environmental noise than other types of noise reduction.

UTC Chip

Many of the cctv ahd camera models we offer have a UTC chip, which allows you to control the internal options of the camera directly from your DVR via the video cable. This is a convenient feature, especially for hidden cameras. If your DVR does not support this feature, you can use our OSD remote controllers to control the menu of these cameras remotely.

AHD is an open standard for trait HD analog video transmission that uses traditional coaxial cables – it does not require replacing existing cabling, and it is a much cheaper alternative to IP cameras. AHD currently offers 720p resolution and long transmission distances (inferior only to HD-SDI over twisted pair / CAT 5).

Similar to HD-CVI, and unlike HD-TVI, AHD does not have an image processing engine and is therefore less susceptible to image quality degradation over long distances. This makes AHD a good choice for surveillance applications with a high number of remote locations that need to be served by a central system. It also has the advantage of a low data rate, which reduces power consumption and signal noise on the line.

Easy Installation

Many cameras these days are not only designed to be as easy to install as possible, but they also come with mounting brackets. This way, all you need to do is to drill holes where you want the camera and then screw it in place. For a professional-looking installation, you cctv ahd camera should consider hiding the wires behind the wall. This will prevent thieves from cutting or splicing the cables.

AHD CCTV cameras use a coax cable to transfer HD video signals to a DVR. They are the perfect solution for upgrading existing analog systems with a minimal cost. They work at the same maximum distance as analog and offer the same image quality.

Whether you’re installing wired or wireless, it’s important to choose the right location for your camera. Make sure the camera is in a good vantage point to capture your building’s entrances and any areas where there’s a risk of crime or unwanted activity. Also, make sure the camera is not too close to a power source so that intruders can cut or splice the cords and take your camera off your property.
