AHD cameras: connect and configure

Many users are interested in how to modernize the existing video surveillance system in accordance with the latest standards. Currently, to obtain a high-quality image, it is enough to install AHD cameras.

Let's consider one of the comparatively "young" standards, which has already managed to occupy its own niche in the implementation of effective video surveillance systems.

What is technology?

AHD cameras - what is it? The innovative format facilitates the transfer of images and sound over standard cables over a distance of more than 500 meters without delay and loss of image quality. In fact, technology is nothing more than a successful symbiosis of analog and digital signals.

AHD cameras become a real discovery first of all for those users who need to establish ultimate control over the object, monitoring what is happening on the site thanks to a high-quality picture. Consumers who resort to the installation of such equipment, get rid of the need for drastic changes in the system of cable routes.

Modern AHD cameras - what is it? First of all - a reliable solution that allows you to save money on organizing effective video surveillance. Despite the budgetary cost, the technology works perfectly when connected to conventional network devices without the need to establish complex settings.

Features of operation

AHD cameras can function in several modes: as standard analog systems, in high resolution or as IP technology. This allows to combine in a single system already installed on the facility visual control devices with devices that function in an innovative format.

The technology supports work with CMS-systems and cloud services. Therefore, setting up the AHD-camera is not difficult for those users who are familiar with the organization of video surveillance with the help of long-proven means.

In the process of operation of the cameras of the new standard, it is possible to connect alarm inputs and outputs, activate the information backup system.

Structure

The basis of the technology is the following elements:

• An image processing processor connected to the signal transmission unit in high resolution.
• Special audio and video codecs that form an available signal for a digital processor.
• Megapixel matrices that convert the light flux into electrical signals.
• Innovative lenses, which significantly improve the clarity and overall picture quality.

Connecting an AHD camera

The most relevant for those who seriously think about the application of technology, there remains the question of how to connect this miracle of engineering thought. Let's look at how to integrate AHD cameras into a video surveillance system.

To begin with, it is extremely important to form a general understanding of the structure of the future scheme. Therefore, it is necessary to finally determine what kind of observation is required at the moment: external or internal.

Purchasing AHD cameras, you need to consider the area of the room or the object as a whole. Features of individual areas require the use of a different number of cameras, adjust their operation in accordance with specific conditions.

If we talk about the storage for information, then as such it is necessary to select hard disks, the volumes of which are sufficient for saving video files of quite impressive size, since here we are talking about a picture in high resolution.

The type of the system being designed deserves special attention. If it is necessary to use IP-technology, it is recommended to use wireless connection of cameras. Realizing other schemes, you will have to stock up a two-wire KVK-cable and special DC-connectors.

How to connect an AHD camera? The device can be powered either from the AC adapter or from the built-in battery. You can also use the Ethernet cable to connect the surveillance device, which can be an effective energy source if necessary.

Technology advantages

Street AHD-camera differs from widely demanded systems HD, IP and SDI following advantages:

• Relatively low cost.
• Transmission of a quality signal without the installation of auxiliary equipment.
• No need for training of personnel for the operation of the surveillance system.
• Simple modernization of the existing analog circuit.
• Slight signal delay.
• The highest quality picture when broadcasting in real time.
• AHD-cameras are distinguished by the presence of a durable, sealed housing, which allows the equipment to function without problems in domestic climate realities.
• The presence of infrared illumination allows observation cameras to function at night as efficiently as during the day.
• You can control the system remotely from anywhere, where there is a high-speed Internet connection.

disadvantages

First of all, the organization of a video surveillance system using AHD-cameras will be an order of magnitude more expensive in comparison with the same IP-registrars. Especially tangible investments will be in the implementation of large-scale projects.

To connect one AHD-camera to the power supply, two cables are required. At least, such a method of connection at the moment is the only possible for the introduction of technology. At the same time, in order to organize a surveillance system in IP format, it is enough to use one cable that will satisfy the need for energy for more than a dozen cameras.

But the main drawback is the lack of the ability to view data without a special device that is responsible for changing the video format. Since the signal transmission is not compressed, the camera can not be directly connected to the monitor.

Finally

As you can see, AHD technology has all the advantages that are typical for the analog and digital format of transmitting visual data. In addition, the standard is practically devoid of shortcomings. Therefore, we can safely consider the innovative format as a good prospect for the future.

The justified decision to organize a surveillance system based on AHD-cameras looks in cases when it is necessary to obtain an easy-to-use, extremely effective budgetary tool. When the old scheme is modified, this option avoids the unnecessary expenditure on the organization of a new cable structure and personnel training.

All of the above features make replacing the old video surveillance system with AHD cameras completely justified.
