What Does security cameras for retail shop Mean?

News Discuss 
Prior to now, a surveillance security system ordinarily consisted of a number of cameras linked—possibly hardwired or wireless— to a digital video clip recorder (DVR), which recorded the images and displayed them on a closed circuit television (CCTV) or check.
