A new era for video surveillance
Article published in the iVT Magazine.
The next generation of solutions for video surveillance equipment is based on open-network technologies such as IP and Ethernet. These solutions provide operators with richer details and improved functionality that can help them make better decisions. It also enables OEMs to create more integrated vehicle systems that saves cost and offers a more user-friendly human-machine interaction.
Traditionally, video surveillance equipment has relied on analogue CCTV solutions. The drawbacks of these solutions include low flexibility and scalability, high cost, and limitations in image quality. The video surveillance-equipment manufacturers have responded by creating the next generation of solutions based on open-network technologies such as Ethernet and IP. These network-based video solutions are steadily growing and are now moving into the vehicle industry, where the technology has already been adopted in trains and buses.
This new technology improves the image quality, system scalability and flexibility, providing surveillance systems with more accurate and detailed data from additional locations but collected at the same instance. This also affects system cost, as several cameras normally share the physical network. It is also possible to use an already existing network, because these devices are based on common standards and can. Network cameras may also be able to use power-over- Ethernet (PoE), reducing the need for extra power cabling and providing data and power with only one cable.
Analogue CCTV solutions can still be used by integrating them into the digital video world with converters, preventing the loss of previous investment cost, but gaining some of the benefits from the network video world. Unfortunately, not all of the benefits can be utilized with such a solution.
Videos no longer need to be retrieved from a dedicated recording device – this can be achieved through various network-related access methods, both wired and wireless. In addition, onboard display computers such as the CrossControl CCpilot XL and the new CCpilot XM can act as instant local viewers or control instances in vehicles, without disturbing recording and remote monitoring. These onboard display devices also provide functions for displaying multiple video streams simultaneously and can at the same time record videos locally upon request, or be configured to automatically do so.
An additional ‘spice’ is that a system solution, using network video solutions, may be able to encode specific data patterns into the video streams already at the camera location. This specific data pattern can be used, together with the new safety-enabled CCpilot XMs, as a system solution able to meet safety certifications such as IEC-61508 and ISO 13849-1, with aspect to video monitoring functions.
