I have a skunk that is trying to adopt me. Since I didn't want to hurt the little fellow, the idea of the Yard Enforcer really appealed to my sense of a ethical solution to the situation. With a sudden noise and a little squirt of water each night, I expected him to seek his fortune else where. So I sprung for the Orbit Yard Enforcer.I thought Orbit, It's a big name company. They have been around a long time. They build all kinds of advanced yard watering products. I can trust them. I am sure they will build a reliable quality product. I can depend on Orbit to deliver a product that works as advertised. Orbit won't over hype some piece of junk product just to snag a few fast bucks like some vendors. Well it doesn't seem to have worked out that way for me at all. What could I have been thinking? I guess the joke is on me. I am such an idiot.Their advertisement for this product states "The heat and motion-activated sensor detects movement from up to 40 feet away and triggers the valve to spray a burst of water." It might detect a charging elephant or rhinoceros 40 feet away but for humans the best we could squeeze out of it was about 20' (sometimes) and 12'-15' (reliably) depending on whether it was day or night, the adjustment of the range sensitivity control, the height of the IR sensor, and the vertical angle of the IR sensor. During the day when the sun was high about 12-1pm in no wind conditions, the unit will just activate for no apparent reason about every 10 minutes. I am guessing the heat and bright light triggers it.Day or night, small animals don't seem to trigger it until they are within 1-3 feet of the sensor. Using only fresh batteries, I lowered the sensor and tried every angle available on the locking vertical adjustment knob. Along with multiple tests using the full adjustment range of the IR sensor sensitivity control. It makes you wonder what is the actual IQ of their " INTELLIGENT SENSING TECHNOLOGY:"On my attached video, the Yard Enforcer is to the left just barely out of view because I wanted to catch the skunk's full reaction to the sudden burst of water. Judge for youself, do you think this should be enough motion to get a yard enforcer going? When he stops to chew his fleas, he is right in the center of the IR sensor's sweet spot which is about 10 feet away. This yard enforcer/skunk ballet has been going on for 5 nights.My trail camera's motion sensor catches the skunk action. It was cheaper than the Yard Enforcer. It has a IR sensor, Full color 24 MP camera for stills and videos, full night vision, water proof case, IR light bank, USB interface, SD card... You would think for the price of the Yard Enforcer, they could deliver a sprinkler that turns on and off when the skunk walks by.I don't doubt that a bear, deer, cow or horse would get the yard enforcer attention. Just don't count on the parts about a skunk, dog, cat, bird, rabbit or raccoons. Funny, they didn't mention squirrels.
