Most businesses these days use security cameras to monitor property throughout the day. Some homeowners also use surveillance equipment. The technological challenge is to provide a rapid analysis of high-resolution footage on a real time basis or as near as possible without losing accuracy.
Imagine a small household decoration business with just 50 employees that’s located in an industrial estate on the outskirts of a medium sized city. There will be large doors for goods delivery and dispatch that need to be monitored over 24 hours against any intruders. Even small manufacturers will have sizeable stocks of raw goods and materials, IT equipment and other office appliances and miles of valuable electrical wiring.
Security cameras will also monitor a car parking area for employees and visitors and certainly the main entrance and reception area. Cameras may also monitor some of the manufacturing process for safety and efficiency reasons.
A small business probably cannot afford to employ even one individual to watch the monitoring screens 24/7. Camera footage can accumulate and become useless over time if not analysed quickly. There are serious issues with personal and corporate data protection if unauthorised individuals access any stored data. The monitoring, analysis and storage tasks become greater as the business grows. For larger businesses, the management of surveillance footage is a major undertaking.
Real time analysis
Speedy analysis in real time is of major importance in any surveillance footage. You need to know quickly if any intruders or other security threats are lurking in the background. A business may require a comparison between two manufacturing or other industrial processes to choose the most efficient and cost effective. But real time analysis and instant analysis can be strewn with errors and false assumptions. An individual analyst may not have the time to identify any curious object on the footage correctly.
One of the main technological advances in analysing the surveillance footage is to produce a summary over a given time period. The user will also have the means to access the original footage. A number of summaries from different cameras may be displayed on a screen together to give a full picture of what has happened in different locations around a property, or during industrial processes, over a specific time range. This kind of real time analysis allows the end user to extract all objects of interest from the accumulative footage database.
Storage and data protection
Some businesses require a full record of surveillance footage to be stored for any future analysis. A storage infrastructure with easily available access to data can be an expensive undertaking for any business. This is even before all matters concerning data protection are taken into account.
One solution is to connect network cameras, footage and encoders to a service provider’s storage platform. The user will be able to view the footage from any internet connected device. This provides a more cost effective video surveillance system for small businesses, as well as a dramatic reduction in upfront installation costs of the surveillance system. The business will be able to add extra cameras, or remove them, without incurring extra hardware costs.
Cloud storage provided by a hosting company gives an instant access to surveillance data for small businesses. The company needs to pay only for the storage capacity it uses. The disadvantage is that unauthorised individuals may access or steal the information. The traditional data protection solution has been to use back up servers and workstations. Deduplication technology has cut the amount of storage capacity required by eliminating redundant or duplicate data from any batch.

Image resolution becomes important for surveillance footage, as many processors do not perform very well when recording in real time. Technological advances have developed a mega pixel, high definition surveillance system that supplies better image clarity. High definition surveillance cameras ranging from 1 megapixel to 18 megapixels also provide a greater redundancy in the overall system, thus improving security and data access.
The analysis of surveillance footage has improved significantly with technological developments. Compressed real time summaries, hosted storage facilities and high definition imaging have lowered costs and improved surveillance processes for businesses.
