How to Configure a CCTV AHD Camera
The camera can be configured to operate in AHD mode with a modern HD security DVR or CVBS mode for use with an older analog system. This allows you to upgrade your existing analog surveillance system with little effort or expense.
This technology also offers longer cable transmission distances than traditional 960H analog CCTV systems. This is achieved by using copper clad aluminum coaxial cables with video baluns or prefabricated plug and play cable.
High Definition
High definition CCTV cameras offer high resolution imaging that is important for preventative security surveillance as well as providing effective evidential video to help authorities identify people and situations. The clarity of HD video captures a person’s facial expressions, eye movements and other subtle details that are not captured with standard definition camera footage.
An HD surveillance camera requires an compatible monitor that can display high definition footage and will also support the extra detail provided by the HD cameras. A widescreen format monitor will best show the enhanced image quality of an HD camera.
Another advantage of a high definition camera is the ability to use it over existing RG59 coaxial cable, rather than needing new network infrastructure or purchasing expensive video baluns to extend cable runs. This makes it easy for customers to upgrade their existing CCTV systems or to install a new security system.
The high-definition cctv ahd camera is compatible with any existing DVR recorder and will also work with many analog CCTV monitors. Some of the most popular models have pan, tilt and zoom (PTZ) capabilities to provide an effective range of view for surveillance. They can also detect motion, alerting you to movement in the area and allowing you to remotely adjust the zoom and focus of the camera. Some models even come with night vision to capture clear footage in low light conditions.
Wide Dynamic Range
In surveillance, glare and light reflections are a common problem that can cause the camera to produce blurry footage. Wide dynamic range helps to mitigate these issues by balancing out any harsh varying lighting conditions.
When WDR is enabled, the camera can capture more detail in brighter areas and provide a better image overall. The WDR technology works by capturing multiple images with short and long exposures, then merging them into a single frame. cctv ahd camera The end result is a clear and crisp picture even in challenging lighting conditions.
With this technology, your CCTV cameras will be able to clearly see the car driving down the street, people in the bank, or any other details that might otherwise be obscured by sunlight or other varying lighting conditions. WDR is a great feature to have for many applications and is often used in offices, rooms with windows, garages and other areas that can be prone to glare and reflection.
We recommend all of our customers to use a camera with a wide dynamic range if they are going to be installing the cameras in high contrast lighting conditions. Having the capability to record more details in these environments will greatly improve your overall security and safety.
Infrared Night Vision
For surveillance cameras that need to work in poor lighting conditions, you can choose a model with infrared (IR) night vision. These cameras use LED lights to emit infrared radiation that’s invisible to the human eye. The light bounces off objects in the camera’s field of view and hits the camera’s image sensor. The sensor converts the reflected infrared radiation into electrical signals that form the video image.
When selecting a cctv ahd security camera with IR night vision, it’s important to look at the number and power of the IR LEDs. The number of IR LEDs determines how much light the camera can receive, while the power of the IR LEDs dictates how far the IR light can illuminate an object.
Some cctv ahd cameras with IR night vision also have advanced low-light imaging capabilities. These technologies include features like an IR Solar Battery camera cut-off filter that blocks visible light from entering the sensor and sophisticated image processing techniques that enhance dark footage.
It’s important to note that IR night vision only works in ambient lighting conditions. When the camera is in complete darkness, it will typically switch to black and white recording. To ensure that the camera can operate in your environment, check the specification sheet to see if it has an IR illumination distance of at least several feet.
Power Over Coax
Powering CCTV cameras requires a lot of electrical wiring, which can be time-consuming and expensive. With new technology such as Hikvision’s TVI cameras and DVR’s, this issue has been resolved with Power over Coax (PoC). This means that the cameras can get the power they need through a single coaxial cable connection. This removes the need for separate power wires and makes it a much easier installation for installers.
This technology works using a twist-fit BNC connector that transmits both data and power over the same cable. This is a great way to upgrade existing analog systems to HD without having to run new wires for power and video. It can also be used for longer distance connections by adding signal boosters or repeaters.
To make use of this feature, it is important to check if your coaxial cables are compatible with the chosen technology. Also, you will need to consider the power requirements for the cameras and recorders to ensure optimal performance.
Finally, you will need to determine the scalability of your security system. How many cameras do you need and will you need to add more in the future? It is crucial to think about these things before making a purchase. This will help you decide which camera type is right for your security needs.
