Using a motion-activated floodlight outside your home is a good idea to deter unwanted visitors, but this one takes that concept one step farther - it actually talks to them! Choose from among three pre-recorded messages: "You are tresspassing!", "Warning! You are being videotaped by a security camera!", or the sound of a dog barking. The passive infrared (PIR) motion sensor can be adjusted so it picks up people only from a speecific area, and the lights can be pointed to the same or a different spot. There are adjustments for the range of the PIR and the time the floodlight remains on. The video camera points the same direction as the PIR and will capture up to 500 video clips (20 sec) per GB of memory. Most surveillance cameras do nothing about deterring potential criminals, they only passively record whatever happens and you have to hope you got a good enough picture to help find the guy. This camera shines the light of day on crooks and tells them they had better leave without committing any crime.
