AHD and IP cameras comparison

Among modern video surveillance cameras, two standards such as digital IP and analogous AHD high-definition ones are most popular. High demand for video cameras belonging to these two categories is caused by their HD-CVI and HD-TVI formats improved in comparison with the other old, outdated formats. HD-CVI and HD-TVI formats differ from each other and therefore they are optimally suitable for various purposes due to their characteristics.

Features and benefits of IP and AHD video surveillance systems

Large-scale security video surveillance systems consisting of 16 and more video cameras with the possible increasing of their number, is easier and more beneficial to organize from digital cameras, and not only because there is no need to lay a separate cable to each of them. The IP address is:

Quick search of the right camera in a local or even global network;
No need to buy a dash camera;
Video archivation and online viewing from the cloud service.

In addition, IP video cameras can boast the following benefits:

Resolution up to 12Mp and more;
Equal quality of recording both moving and static objects by replacing the interlaced scanning with the progressive scanning;
Built-in microphone and the memory card connector, as well as alarm inputs / outputs (optionally);
The possibility to connect to the router via wi-fi;
PoE technology supporting.

AHD cameras can boast relatively small (in comparison with digital ones) maximum resolution of 1080p FullHD, but it is quite enough for high-quality video stream recognition and the price of devices is much lower. If the IP camera is guaranteed to transmit a signal of this quality without distortion via the twisted pair to the distance of 150 meters, then in the improved versions of analogous cameras this distance reaches 500 meters. In this case there is no 1-5 second playout delay traditional for digital video. The main reason for purchasing such devices is full compatibility with the old analogous equipment in terms of protocols and ports. AHD cameras make it possible to upgrade the existing surveillance system without expenditures.

Both IP and AHD cameras are equipped with the smart image quality correction software, for example, 3D-DNR or D-WDR technologies. In addition, they can be rotary, and they are equipped with a varifocal lens, and also they are available in various housings for indoor and outdoor installation.
