The original meaning of the mid nineteenth century term "a curate's egg" was not something partly bad and partly good. It was something that is obviously and entirely bad, but is described out of politeness as nonetheless having good features that redeem it.To be polite, the range between the detector (the transmitter) and the alarm (the receiver) with the receiver behind a two course brick wall was reliably in excess of two hundred yards, but became intermittent beyond that. However, occasional alarms could be received at 400 yards.The system consists of the PIR alarm (packed in its own box) the receiver (in a much smaller box) and the remainder of the items loose in Amazon's own shipping box. Sorry Amazon, but a two foot twist of brown paper does not cushion these contents in a 12" x 9" x 7" box.The loose contents included three separate folds of "instructions". If there were a contest for the worst set of instructions, ever, all three scraps of paper would be serious contenders. All three were in such fractured Chinglish that I gained a better understanding from the vendor's web page. A short video there did at least show me what to do with one small piece of plastic loose in the shipping box. It has a round hole and can replace the oval hole in front of the PIR sensor itself. Pry it out and force the new one in. Why you should do this is left to the curiosity of the installer.Besides being incomprehensible, some of the drawings obviously refer to different models of equipment, or perhaps earlier versions. With my critical hat on, and considering how bad it all is, I would hope the items I received were a prototype for usability trials.Also loose in the shipping box was a small plastic base which can be screwed to a wall and used to mount the alarm, a bag of screws and rawlplugs, and a small USB charger with American style twin pins.When I took the detector itself out of its box it rattled, never a good sign. There were also a couple of pieces of plastic and a solitary machine screw. These were obviously intended to mount the detector on a convenient wall. I hoped the rattle was the nut the machine screw ought to engage, so I removed the back of the detector, shook it, and a nut fell out. Hence, I was able to take the photograph of the detector circuit board, very densely packed with tiny surface mount components. The nut sits in a shaped recess in the plastic. A dob of glue to keep it there in transit would be a good idea.I replaced the back (with its rubber gasket) then attached base to detector using the machine screw. The attachment is a ball joint, but must be tightened sufficiently before all is mounted on a wall as there is no subsequent access to the machine screw, A cunning design.On the top of the detector there is a small solar panel for power. For initial charging of the battery there is a USB socket on the underside. It and two switches are protected by a rubber flap. One switch determines whether a red LED flashes when the PIR detects movement. It seems an unnecessary give-away to me. The other is OFF, High, and Low. Off is obvious (although considering everything else this may be an unwarranted assumption.) High and Low refer to how high above the ground the detector is mounted. This also has to do with whether pedestrians or vehicles are your target, but the instructions are abysmal.If the detector battery level becomes low it apparently reports this to the receiver which somehow notifies the user of the problem, but the instructions are....abysmal. However, to recharge the battery using the USB socket will mean unscrewing everything from the wall (or a very long extension cable.) Hint, a quick way of detaching detector from its mounting plate would be a good idea, and coincidentally might help with the inaccessible ball joint screw.The alarm itself is a slim rectangle of black plastic which takes three AA rechargeable batteries (supplied!) and is recharged using the supplied charger, It has four buttons in a row on one side. Pressing one of these cycles through the different melodies the alarm will play when activated. Similar or maybe identical noises to the ones in a mobile phone - the ones that nobody ever chooses. Pressing the next button cycles through the five levels of volume. I think a third button sets the choice of the first two, but I am not sure. If not, I have no idea what it does. The fourth apparently, possibly, may be an ON-OFF button. The instructions suggest so, but I don't care that I am repeating myself, the instructions are abysmal. The button is engraved with what I interpret as a light bulb symbol. There is no indication of whether the device is on or off. No LEDs appear to flash. What indicates a low battery state in the alarm, or the detector remains a mystery.Several detectors, and alarms, can (if I have understood the near incomprehensible) be linked together in a network of zones, and the alarms can be set such that different chimes sound for intrusion in different zones. I would need to sure one detector and its alarm worked reliably first!An external relay would be a thoughtful addition, so I suspect slim chance of that. Integration with Amazon Echo or Google Home would add immense value; but on current form I can only shudder thinking how useable its app would be.Afternote:I have moved the detector. My original site, perfect for detection, was not so good for solar recharging. The detector now seems to be working reliably even during the hours of darkness but my original interpretation of how to change the "chimes" was mistaken. I can cycle through them, but the same one always plays when the detector does its detecting.This must have been a prototype. Or perhaps it is intended to be a protracted puzzle. In truth I now have it functioning - just. It could be so very very much better.Why not an external battery pack for the detector - easily removeable to recharge? Why not a separate solar panel so it could be located in the sun while the detector is concealed? Why not sort out the alarm? Why not engage a technical author to write a manual; even charge extra for it.16 February 2024. After just over a week the system stopped working. I've removed the sensor unit and brought it inside to put it on charge.. My thought being there have been several very overcast days so perhaps the solar panel was not getting enough sunshine. It has been on charge for 18 hours as i type this - and it still does not work!

I’ve tried driveway alerts from 1ByOne, Satisure, and others similar to Satisure such as Physen. This one from Fuers is in most ways the best.You get a very complete kit. The instructions are good and it’s easy to set up. Screws and wall plugs are included for the sensor and receiver. Three AA batteries are supplied for the receiver (they’re pre-installed but individually plastic-wrapped, so you’ll need to extract them and remove the plastic). The receiver can also be powered via the microUSB port, if you have a spare cable and convenient USB source such as an old phone charger.The sensor and receiver are paired, on delivery, so you just have to fix the sensor to something using four screws and power the receiver. It would be worth charging the sensor with a phone charger first though, through its microUSB port. After that, the solar panel may provide enough power to keep it going.The receiver can be used free-standing or attached to a wall-mounting plate, powered with batteries or an old phone charger and microUSB cable.The sensor is said to be rainproof, and does look it, but after experience with similar products I’d recommend taking extra precautions. I just applied waterproof tape around the join where the back of the unit attaches. It may not be necessary but I’d rather be safe than sorry. Obviously, you can’t put it under cover, if you want to use the solar panel.My setup is working reliable over about 50 metres, through a fence, an external wall and an internal wall. We use it just to get advance notice of anyone coming down the drive (there’s no other way in except through dense hedges and 2m fences from neighbouring gardens). Most of the alert tones are dreadful, like those with doorbells, but a few of them are ok as simple warning sounds. They go VERY loud on maximum volume, louder than other driveway alerts or doorbells we've had. It's easy to hear across a large house.So far, we’ve had no false alarms. People and vehicles are detected reliably. It also picked up animals like cats, foxes and badgers until I increased the sensor height to 2 metres. Now the only animals it only catches roe deer! It’s too early for me to say whether the solar panel will maintain the sensor’s charge in the middle of winter - fingers crossed.The only annoyance is that the mains adapter they supply, with tethered microUSB cable, has a USA plug. Fortunately, I have plenty of spare chargers and microUSB cables, so I run the receiver that way.If they supplied a UK charger, I’d unhesitatingly award a full five stars (based on limited experience to date). Am I going to be mean and deduct a star for that? No, because batteries can be used instead, and most of us have spare chargers and cables, by now. So five it is. Or 4½ if I could.Sorry - long review. I hope it may help someone.
