According to IHS, multi-sensor panoramic cameras are the fastest-growing segment of network cameras. The projected annual growth rate for 180° and 360° cameras between 2014 (1393) and 2018 (1398) is about 30%. This growth rate is twice that of PTZ cameras and significantly higher than that of box cameras and fixed dome cameras in the network camera market. This rapid growth indicates that there is still a strong demand for these solutions in the market.
However, despite the benefits that these cameras can bring to security systems, multi-sensor panoramic cameras have specific needs that could present challenges or difficulties for their deployment. Therefore, it is crucial for installers to assess the advantages and potential problems associated with these systems.
Bandwidth and Storage
The increasing demand for higher-resolution video and the adoption of multi-megapixel cameras create a demand for more extensive network and video management software (VMS). Customers want to deploy more cameras in their network, which is closely linked to the need to reduce storage costs and bandwidth. For multi-sensor cameras, this depends on the resolution and frame rate.
When cost concerns arise, storage locations and memory appear to be crucial. Depending on the customer’s needs, storage can make up 30 to 50% of the total cost of a video surveillance project, often exceeding the cost of the cameras themselves or VMS software licenses. The demand for higher resolution and multi-sensor cameras significantly impacts the network, affecting both bandwidth and storage. Since storage is the largest cost factor, reducing storage costs has the greatest impact on lowering the overall project cost.
Several tools are available to help manage this issue. These tools use multi-streaming capabilities, which enable users to utilize video streams from multiple cameras for different purposes, such as lower-resolution video walls or streaming to multiple users. On the other hand, during specific events based on camera-triggered patterns, high-resolution recording can be enabled.
Another feature that helps save memory and storage space is motion-triggered recording, where recording starts when something moves within the camera’s field of view. However, this feature comes with the risk of missing important events or incorrect recordings when there is no motion. The solution to this problem is continuous recording with dynamic adjustments to frame rate and resolution when an event is detected. This approach allows the camera to increase the data rate and record more details when needed.
Evaluating the Pros and Cons
Panoramic cameras offer many advantages, but they are not the only solution available in the market. These cameras enhance situational awareness. It is recommended that users test the cameras before making a final purchase to ensure they meet their needs. A competent installer should be able to offer multiple options to users.
