Modern digital IP security cameras have replaced older analog CCTV security systems so as to provide better clarity, performance, features and recording/storage options.  They no longer need to be a separate independent system - IP security cameras can be integrated into your existing IP computer network for better management and ease-of-use.  In addition to mitigating internal and external threats to your company, IP security cameras can also provide video analytics in a retail store environment.  Video analytics for example can help you determine where the customer "hot spots" of your store are enabling you to physically target your marketing efforts.
