For quite a few years now, the Unit For Observation (UFO) has been a proven high-end solution for construction site security. The UFO is particularly suitable for remote locations that have no available source of power or means of providing data. The all-in-one system - with its hybrid, environmentally friendly power supply - is a rugged looking unit, the function of which is quite unmistakable, something that helps create a deterrent effect. A day/night camera provides clear images no matter what time of day. A sound function gives intruders a clear warning that they must leave the site, without intervention being required. The UFO monitors the construction site with sophisticated motion-sensor technology. This ensures speedy detection of intruders. Kooi Observation Centre, the 24/7 central surveillance centre, actually monitors and analyses every alarm, thus avoiding unnecessary interventions. The next day you are sent a concise report by e-mail about any incidents. The UFO prevents damage to equipment and materials. Losses caused by delays through work needing to be halted and not meeting deadlines are also prevented. Hiring expensive security staff is no longer necessary. It is also possible to arrange a combination of UFO and security personnel for larger projects. The flexibility and mobility of the UFO are improved when the UFO trailer is used, giving added value. This trailer enables you to move the UFO to your next location.
