New from Dahua Technology
Dahua have launched a new HD system known as CVI, this is the same as SDI mentioned above but has the ability to travel over longer distances, i.e. SDI has a maximum distance over RG59 cable of 80mts, whereas CVI will work up to 250mts providing greater flexibility.
They can be supplied with fixed lenses or motorised vary-focal lenses, some of the models also have built in mic’s for audio and all cameras are day/night with built in IR’s ranging from 20mts to 60mts.
The Dahua range of DVR’s all support HDMI and VGA monitors and connection to mobile phones and tablets. The units range from 4 channel to 32 channel and can be fitted with hard drives from 1TB to 16TB depending on what recording time is required.
Another feature is that they are all tribrid’s, that is the support Analogue, CVI, TVI, AHD and IP on the same unit, therefore making it easy to upgrade as and when necessary.
