Digital network cameras which are hooked up to the existing network view footage and then the images are relayed to a computer or server where the images can be viewed, stored and retrieved as required. One of the benefits offered by digital network cameras is that of the zooming as well as tilting ability. This ensures that even difficult angles can be monitored. Retail stores where the digital network cameras have been installed have reported an improvement of security while also being able to make the most of footage to enhance customer service as well as increase sales. As such it is a far cry from strictly viewing that which has already happened. By making use of modern technology as offered by IDtek retailers can now also use the security system for marketing purposes. If considering the benefits of addressing two main concerns such as customer service and marketing together with that of security, it is understandable that so many retailers now switch to digital network cameras.
