Video surveillance with high-resolution cameras provide real-time viewing from your smartphone or computer. A DVR and / or associated smartphone application will allow you to record and store videos. The installation of video surveillance in discrete areas in the restaurant, especially the backdoor, vault, cashier, and kitchen will allow you to monitor employees and customers, and keep possible crime at bay. Parking lots and exterior areas are also potential spots for crime, and should be considered when setting up your surveillance cameras.
