CCTV AHD Camera Features
AHD technology allows you to use standard RCA or coax cables for 720p high-definition video. This makes it an excellent choice for upgrading existing CCTV systems on coax cable.
EchoMaster AHD cameras are an effective solution for commercial driver monitoring, especially in low or no light conditions. These cameras can help to curb driver fatigue, distraction, and drowsiness.
AHD technology
AHD technology is a new HD CCTV transmission standard developed by Korean chip-set manufacturer NextChip. It uses existing coaxial cable infrastructure to transmit 720p high definition video footage at a longer range than traditional analog equipment. This technology is comparable to cctv ahd camera HD-SDI and is compatible with a wide range of camera models. However, it has a lower maximum resolution compared to other HD technologies.
AHD cameras are ideal for fleet management because they can be used to monitor commercial drivers and provide detailed information on driver behavior. These cameras can also record live transmission and can be viewed remotely on mobile devices. They are easy to install and come with features such as IR night vision and a high-resolution image sensor.
Some AHD cameras can capture images at a 360-degree angle, making them suitable for securing large areas. They can also use a WIDE DYNAMIC RANGE function to improve image quality in bright and dark environments. This feature is especially useful when shooting vehicles in a parking lot. In addition, some AHD cameras can be fitted with GPS, which makes it easier to track the location of your vehicle.
IR night vision
A good night vision camera will feature powerful IR illumination that can light up complete darkness. This is especially important for security applications where ambient light cannot be controlled such as retail stores, warehouses, and offices with no windows or natural lighting. You should look for cameras with a 3.6mm lens and 36pcs IR LEDs for maximum illumination distance.
AHD technology offers a simple upgrade from analog CCTV systems by using existing coax cable. This means that you can reduce installation cost and time while gaining better high-definition image quality.
Some of the latest AHD security cameras also include a range of advanced features such as Wide Dynamic Range, IR Night Vision and Anti-fog capabilities. This allows you to capture a clear image in bright or dark areas and improve the contrast of images. You can select the video mode of a camera through its OSD push button on the cable or via a DVR that supports UTC menu control. This ensures a high level of flexibility and usability. Moreover, these cameras have an IP66-rated weatherproof design so they can be used both indoors and outdoors.
H.265 video coding
Using H.265 video coding technology, you can have the same footage quality but at much lower bitrates, which saves storage space and bandwidth. Some manufacturers even use smart codec technologies that adjust the bitrate on-the-fly based on background and foreground analysis. However, these smart codec technologies require a PoE camera and NVR from the same manufacturer.
This uncompressed HD video format is able to transmit over long distances and can be used with existing coax cable. This makes it an ideal solution for upgrading older CCTV systems. It also offers lower cost and less latency than HD-SDI or network IP cameras.
For the best results, you should choose a surveillance system that uses the latest H.265 video coding technology, which improves coding efficiency by reducing the size of the video file while retaining incredible visual quality. It requires about half the storage space of its predecessor, H.264. You can also use a hybrid DVR that supports both H.265 and MJPEG formats to upgrade your system over time as budget allows.
Wide Dynamic Range
The ability to capture a greater range of luminance is an essential feature for CCTV cameras. It allows for the camera to capture images in a variety of lighting conditions, even when the contrast is high. This technology is used to improve image quality by avoiding overexposed or underexposed areas.
For instance, when a camera is situated in a parking area it is often exposed to the sun and this can lead to glare. However, with wide dynamic range, you can overcome this issue. It works by taking multiple images at varying exposures and then combining them to create a single image.
The value of a camera’s WDR is typically expressed in decibels (dB). Different manufacturers use dB differently, so the value you get from one Solar Battery camera brand may be different from another’s. In general, a higher dB value indicates a wider dynamic range.
Audio Capture
Adding audio to CCTV recordings provides more context and information. It can also help you identify suspects by hearing their voices. This feature is especially useful when people are hiding their faces, as it can provide clues to their identity. Additionally, many trespassers and thieves don’t speak during illegal activities, so adding audio can help you capture evidence that would otherwise be missing.
Audio recording capabilities depend on the type of camera you have. Traditional CCTV systems that use coaxial cables to transmit data don’t usually have audio because the technology can’t natively support it. However, IP cameras can record audio by using their microphones. You can tell if a camera has an audio recording capability by reading its specifications or looking at the camera itself. Most of these devices have a small hole or input at the back that indicates audio recording.
Keep in mind that recording audio CCTV can be a privacy intrusion for employees and customers. Therefore, it’s crucial to evaluate the impact of this technology on privacy and workplace safety.
