Most security camera hard drives may be pre-installed inside a network video recorder (NVR) or a digital video recorder (DVR). That’s the common practice.<\/p>\n

Sometimes other external hard drives may be installed to an NVR or DVR.<\/p>\n

Hard drive manufacturers have especial products for the surveillance market and obviously,  they cost more than the traditional hard drives for a regular PC.<\/p>\n

This type o hard drive is very popular and recommended by technicians and engineers (including myself) who work with professional surveillance systems.<\/p>\n
