Many users interested in how to upgrade the existing surveillance system in accordance with the latest standards. Currently, for high-quality image is sufficient to establish the AHD.
Let's look at one relatively “young” standards, which has already managed to occupy its own niche in the sphere of implementation of effective surveillance systems.
AHD camera - what is it? The innovative format facilitates the transfer image and audio over standard cables, for a distance of more than 500 metres without delay or loss of picture quality. In fact, technology is nothing more than a good symbiosis of analogue and digital signals.
AHD be a real boon in the first place for those users that need to establish maximum control over the object, tracking what is happening on the site because of the quality of the picture. Consumers who have resorted to the installation of such equipment, getting rid of the need for radical changes in the cable routes.
Modern AHD camera - what is it? First of all-a reliable solution that allows you to save money on organizing effective surveillance. Despite the budget price, the technology works perfectly when connected to regular network devices without the need for setting complicated settings.
AHD Camera capable of operating in several modes: as a standard analog system to high definition or IP technology. This allows you to combine into a single system already installed tools visual control instrumentation in an innovative format.

Technology supports working with CMS systems and cloud services. Therefore, setting the AHD camera is not difficult for those users who are familiar with installation of video surveillance using long-proven means.
In the process of operation of cameras of the new standard it is possible to connect alarm inputs and outputs, the activation of backup system information.
The core of the technology are the following elements:
The Most urgent for those who are seriously thinking about the application of technology, the question remains on how to connect this miracle of engineering thought. Let's look at how to introduce AHD cameras in the surveillance system.
For starters, it is crucial to form a General idea of the structure of the future scheme. Therefore it is necessary to decide what kind of supervision is required at the moment: external or internal.
Acquiring AHD camera, you must consider the floor space or the entire facility. Features separate areas require different number of cameras, setting their work in accordance with specific conditions.
Speaking about repository for information, as such, should choose hard disks, which is enough for saving video files quite a big size, because here we are talking about the picture in high definition.
Special attention deserves the type of the designed system. If necessary, the application of IP technology is recommended to resort to wireless cameras. Implementing other schemes will have to be sturdy KVK-DC cable and special connectors.
How to connect AHD camera? To eat the device can from the network adapter and internal battery. To resort you can also connect surveillance Ethernet cable, if necessary, can be an effective source of energy.
Bullet IP camera differs from the widely popular systems HD IP and SDI the following advantages:
First of all, the surveillance system via AHD-cameras will be much more expensive compared to same IP registrars. Especially noticeable investment will be in the implementation of major projects.
To connect one AHD camera to the power supply requires two cables. At least, this way of connecting at the moment only possible for the introduction of the technology. At the same time, to organize a system of observations in the format of IP, it is sufficient to use a single cable that will satisfy the energy needs for more than a dozen cameras.
But the main drawback-the inability to view the data without a special device, which is responsible for changing the video format. Because signal transmission is not in a compressed form, the camera cannot be connected to the monitor directly.
As you can see, AHD technology has all the advantages that are characteristic of analog and digital transmission of visual data. Besides the standard practically devoid of drawbacks. Therefore, we can safely consider an innovative format as a good prospect for the future.
Justified the decision on the organization of a monitoring system based on AHD cameras looks in cases where it is necessary to obtain simple to operate, highly efficient fiscal tool. When modifying old schemes this option allows you to avoid unnecessary expenses for the organization of the new cable structure, and training.
All the above features make the replacement of old CCTV system camera standard AHD a fully justified decision.
