Review: Great item and good distance range - Delivered quickly well packaged and its Working extremely well ive used it now for 3 days in several different distance areas to my home i purchased this item as i have to leave my vehicle on street parking or surroundings roads near to my home depending on availability to parking spaces why i needed a long distance coverage and this item is working very good to my requirements I also have purchased rechargeable batteries to maintain top power for the signal distance I haven’t had to change them so far but im very impressed with this product but bare in mind other environmental signals and other cctv can effect the signal range i have a camera in my home and it did effect the signal as i tested it to see by unplugging the camera then signal worked perfectly from another street 500/600yards away i would definitely recommend to anyone and the volume / sound options features are great.
Review: Great Product, well worth doing the mods shown - Works a treat, sets off quite a ROW and has extraordinary range. It covers the whole front of the house and drive so picks up movement anywhere. And contrary to another report it always goes off when my electric car arrives, its MOVEMENT that sets, doesn't matter what it is that's moving. The outside receiver unit is made to run on 2xAA 1.5v batteries, which didn't last long; so for £8 I bought a 240v - 5v adapter (on desertcart). Just needed to remove the rear battery cover and drill 2 holes, then cut off the plug on the 5v end of the adapter, solder the ends to the tabs in the back of the unit then seal so to keep water out. Now it will run forever that its got the mains power. I bought two of the sounder units which are for mains electricity - one inside the house and the other outside, via a timer to work mainly in the dark hours. I made sure to waterproof the outside unit as well. Does it work? YES - has woke me up a couple of times. It's inspired me to now add an outside camera.

## Questions & Answers

**Q: I have two quite largish cats. Would it be sensitive enough for them to trigger it while out on the prowl?**
A: This would depend on how high you have the monitor The birds can set it off if they fly passed the monitor but my cat never sets it off are it is too high up

**Q: Can you get detection alerts on your mobile? Thx**
A: Unfortunately no. It sounds an alarm on the base unit which has volume control and a variety of chimes. Works a dream and does have a loud volume setting if required.

**Q: Does this product work through glass?**
A: Yes this product works through glass, mine is working through a double skinned brick wall but is only about 2oo metres from the sensor but i'm confident it would work at a further distance. i am very impressed with the performance.

**Q: Why did mine go up in smoke after 6 months use?**
A: The external sensor or internal sounder?
