If you are a prospective CCTV purchaser hoping to reap the benefits of system integration and interoperability, don't forget to check out manufacturers' policies on interfaces and SDKs because these could affect the cost and performance of your system in the short or long term.

Integration and interoperability depend on convert the CCTV equipment coding into that used by other systems, and vice-versa.  But interface service levels can vary. Code conversion may be limited to basic functions only, or may support the full system capabilities. The manufacturer may also provide free developer assistance with individual project requirements, or he may charge for both the interfaces and the assistance. It just depends.

The interface may come as part of a software development kit (SDK) - a set of tools which enables a software developer to develop individual applications for a particular device or system. This usually includes source code examples, supporting technical documentation and maybe even a digital test environment - a virtual device enabling the developer to test out his new software.

But developing SDKs is expensive, so nowadays many manufacturers charge for them. Others though, see the provision of free SDKs and free assistance as part of their marketing strategy of facilitating high levels of integration to promote customer satisfaction and customer loyalty. - So thinking about your current or future need for integrated functionality and checking out suppliers' policies can avoid unpleasant surprises and significant costs.

Integrating video with toll payment systems and cash counting systems, and providing mobile access to CCTV systems are examples of many technical feats achieved using Geutebruck's SDKs.
