datasheet and model comparison



What makes a CCTV system really useful is a good and reliable digital video recorder.
The DN series DVR's are the best "hart" for your CCTV system, providing the high performance of latest technologies but still being very reliable and easy to us.



AHD, TVI, CVI up to 5MP
AHD, TVI and CVI  are the latest technologies in the analog CCTV industry. Although very similar to classic CVBS analog video, these new transmission standards get to higher video resolution.
Today's AHD/TVI/CVI cameras provide 2MP (Full HD 1080P), 3MP, 4MP and 5MP video resolution, like our best IP cameras.
AHD, TVI and CVI are very similar technologies, adopted by different manufacturers.
In 2014, DSE was one of the first companies in Europe introducing a full range of AHD DVR. From 2016 our DVR also support TVI and CVI to be compatible with other camera manufacturers. 
These high resolution analog CCTV systems provide high definition, without video latency, still being low cost and easy to install as standard analog systems.
Like any analog cameras, AHD/TVI/CVI cameras can be wired by normal coaxial, mini-coaxial or twisted pair cables up to several hundreds meters.

DN range DVR are multi-technology DVR because they are able to control different kind of cameras

These DVR can be connected to AHD,TVI and CVI cameras providing up to 5MP resolution according to the camera's capability, but are also suitable for old standard analog cameras (CVBS) that can be recorded at 960H resolution.
These DVR detects automatically the technology of the connected camera so they do not require any setting.
In addition, these DVR, can be converted in NVR, recording onvif  IP cameras up to 5MP video resolution.
