Designed for security teams worldwide for application in a variety of conditions and circumstances, the Allen-Vanguard tools range from weapon mounted devices to powerful surveillance systems for use in even the most obscure overcast night light. The NiteWatch is a handheld monocular surveillance device that can be attached easily to both still and video cameras, enabling professionals to record long range night time scenes effortlessly. The Night Vision Surveillance kit (NVSK) contains all the tools required to gather visual information in low-light situations. The NVSK can record high quality still and digital video sequences, measure the distance to the object under surveillance and supply additional covert infra-red illumination. To complete the night vision range, the BlackCat2 handheld thermal imager is a simple-to-use camera for police, coastguard, border guards, customs and security guards alike. Because it is powered by a standard camcorder battery, it is lightweight and portable, making it an essential tool for those in internal security.
