DogBlocker works like an invisible gate for your dog. Place it in a doorway, hall or room opening where you don't want your dog to go. With up to a 20 foot range, just about any section of your home can be gated off. Once activated, DogBlocker waits for your dog to break the invisible barrier, setting off an ultrasonic siren and bright flashing lights.
In training mode, there's also a human-audible buzzer which alerts you that your dog has attempted to cross the invisible barrier. The buzzer allows you to correct your dog's behavior while it happens. Once your dog is trained, DogBlocker can be put in normal mode. In normal mode there's no human-audible buzzer, so it doesn't bother anyone in your house watching TV, sleeping, etc.
DogBlocker's status lights blink every several seconds letting you (and your dog) know it's armed. This indicator is a reminder to your dog not to cross the invisible barrier. This is quite effective in keeping your dog away from the invisible gate, reducing the number of alarms.
Since DogBlocker uses an invisible motion detector, there's no physical gate and you can cross at any time. When in normal mode, you can silently pass through the invisible gate without any audible disturbance. Only your dog is restricted from going through the gated off area.
If you're currently using dog gates, child gates or barricades to block your dog from entering certain parts of your home, these unsightly items can be removed and replaced with DogBlocker. Here's a video of prototype in action (in training mode).
