Below is a sample of a Picture-In-A-Picture Splitter.  Included with the CCTV design at this location is a Cash Register Text Inserter. This is an excellent example of how much information an owner/manager can review by using the recording from a simple CCTV design.

The store front is viewed so that management can "See" all visitors and what product has been served to the customers. The text inserter lets management see how much was tendered on the cash register for the product sold to customer. The smaller picture shows the back storeroom, and is positioned above the rear exit so that management can view product being delivered or remove from this exit.
