As indicated in the drone detection and counter drone pages, a single detection and counter option is not an effective or complete solution as all the different types of technology have their strengths and weaknesses. Therefore, an integrated multiple sensors system is a better option and provides a better chance for success as the weaknesses from one system is covered by the strengths of others.
However, this does not mean that you need to purchase the complete suite of available sensors as every location, venue or facility has their own unique considerations and challenges that may determine that the use of one sensor is unsuitable.
Some manufactures sell complete integrated solutions, some build to client specifications, some forge partnerships with specific manufactures (eg. RF, Optics & Radar) to produce a product, and others source equipment from various suppliers, integrate and sell them as their own product.
Like any product sold worldwide, these products will be marketed with capabilities that may not be realistic or achievable. With so many options and capability variances, only an independent assessment by Counter Drone Solutions will confirm the true capability.
