When HDcctv first came onto the market there was a good feeling about the technology but some in the industry doubted that installers would be able to persuade end users to convert their whole system to an HDcctv system. It was then that many manufacturers notably Everfocus decided that a hybrid HD SDI DVR could be a good stepping stone for installers to persuade their database of customers to move into the world of HD.
There have been two main formats of hybrid HD SDI DVR’s on the market. The 14/2 and the 4/4 ie 14 analogue and 2 HD SDI inputs or a straight 4 analogue and 4 HD SDI cameras on an 8 way unit.
The main reason for this approach was to allow customers to keep the majority of their analogue camera infrastructure but in places that were crying out for HD such as reception areas or gates and vehicle entrances customers could have HD quality.
The Hybrid HD SDI DVR is finding a foothold in the market place as is HDcctv equipment in general. So if you have an area of your site that demands better quality but you need to achieve this on a tight budget then an Hybrid HD SDI DVR is the sensible way forward.
