CCTV - Surveillance Cameras & Alarm Systems
Today’s High-definition CCTV cameras have many computer controlled technologies that allow them to identify, track, and categorize objects in their field of view.
A growing branch in CCTV is internet protocol cameras (IP cameras). IP cameras use the Internet Protocol (IP) used by most Local Area Networks (LANs) to transmit video across data networks in digital form. IP can optionally be transmitted across the public internet, allowing users to view their cameras through any internet connection available through a computer or a 3G/4G phone. IP video can be recorded onto a remote server.
Most common uses of CCTV are crime prevention, control of retail, warehouse, manufacturing processes.
Control of retail
Some software integrates with CCTV to monitor the actions of workers in retail environments. Every action is recorded as an information block with subtitles that explain the performed operation. This helps to track the actions of workers, especially when they are making critical financial transactions, such as correcting or cancelling of a sale, withdrawing money or altering personal information.
Actions which an employer may wish to monitor could include:
- Scanning of goods, selection of goods, introduction of price and quantity;
- Input and output of operators in the system when entering passwords;
- Deleting operations and modifying existing documents;
- Implementation of certain operations, such as financial statements or operations with cash;
- Moving goods, revaluation scrapping and counting;
- Control in the kitchen of fast food restaurants;
- Change of settings, reports and other official functions.
Each of these operations is transmitted with a description, allowing detailed monitoring of all actions of the operator. Some systems allow the user to search for a specific event by time of occurrence and text description, and perform statistical evaluation of operator behaviour. This allows the software to predict deviations from the standard workflow and record only anomalous behaviour.
Integrated systems allow users to connect remotely from the internet and view what their cameras are viewing remotely, similar to that of IP cameras. In one incident, a lady was able to watch her house get robbed and contacted police directly from her office at work
