Review: Very good driveway monitor. Recommended. - Purchased this with an additional PIR sensor to compliment our existing CCTV system and to provide an audible alert when visitors approach our house. The system is very easy to set up - multiple sensors can be added to up to four zones. Each zone can be set to provide a different audio and visual alert so you can easily identify which zone has been triggered. The PIR sensor that came with the main unit was faulty and only worked when very close (within 50cm) to the main unit. The seller (TongWD88) provided prompt and helpful feedback to confirm the nature of the fault before sending a replacement PIR. The additional sensor that I purchased worked perfectly out of the box and the replacement PIR also worked perfectly and arrived within a few days. I have one sensor fitted about 10 feet up in a large tree which overlooks our drive, and another sensor concealed closer to our front door. The PIR sensor range can be set to 6 or 12 metres, so the two sensors are sufficient to effectively cover our drive. The sensors do not seem to result in any 'false alarms' so far. We get quite a few foxes in the area and these do not seem to set the sensors off, though this may be down to positioning of the sensors. The furthest sensor is probably about 30 metres from the main unit, and the PIR signal has no problem passing through the wall to reach the main unit when anyone approaches the house. The PIR sensors and main unit both appear to be well made. The outdoor PIR sensors are weather resistant and come with 'filters' which allow you to focus the area of coverage. This is probably also a likely reason why the PIR's don't seem to generate any false alarms. For an inexpensive solution that alerts you to visitors before they reach your front door, this system ticks all the boxes. Definitely recommended as a stand alone or additional enhancement to existing home security systems.
Review: Does what it should do. - The reason for buying this was due to having two occasions where people have walked up the front path and tried the front door, I saw them on the CCTV but was only alerted to the fact that something had happened as the gate was left open. Hence the search for something to alert me to visitors, welcome or otherwise. The item itself is quite small, the build quality feels fairly cheap and brittle plastic, OK, it is only £40 but I would expect a better quality, this also extends to the speaker, it is fairly loud and does alert you but it sounds muffled. Another reviewer did comment on the voice warning, you can change this so as it is just a tone that plays, I did this as the voice warning was useless. You also need to buy some batteries, 2 AA for the PIR and the base station can run from batteries or be installed to run from the mains with the supplied adaptor, for ease I have used the adaptor however you may want to have some batteries installed so as you can move the base station around (if you have a big house). Installation wise it was very easy, I affixed the PIR sensor to a fence post and angled it slightly towards the front door, the receiver is upstairs in the front bedroom which is used as an office. It was fitted in less than five minutes. Distance between the PIR and the base unit is around 30 feet. So far the item has worked faultlessly, the activity period is quite short so if the postman walks in it sets off, and seconds later when they walk out it goes off again, personally I prefer this as it would alert you if someone was "lurking" outside. One major downside from my point of view is the security of the PIR sensor, it could easily be removed by anyone if they know it is there, there should be some way of securing the PIR head to the base so as it cannot just be pulled off. I know there are more expensive options out there but so far this does seem to be doing what it was intended to do, you do have the option with this to add another 3 sensors meaning the system can run four individual PIRS in different locations around the property.

## Features

- GARAGE ALARM SENSOR picks up any movement 20ft in front of it, and send a signal up to 500ft (in open area) long range back to the receiver which chimes. The passive infrared motion sensor can detect heat movement, 90 degree viewing radius from dead center, can be adjusted by 2 window covers in the kit. With the durable plastic lens and weather resistant casing (waterproof IPV4), it is suitable for monitoring proximity outdoor areas such as driveway alarm, garage shed alarm, gate alarm, etc.
- RECEIVER has an ON/OFF switch and a VOLUME CONTROL. 16 alert sounds are selectable and each melody will play for a set duration, some repeat and sound off for 20s, some are as simple as doorbell rings and only last for a few seconds. Duration is dependent on the choice of the melody you desired. 5 volume levels up to 100 dB (MUTE included), along with the LED light indicator flashing, fantastic to give a visual alert that someone is coming up your door or the perimeter.
- HOLDS UP TO 8 SENSORS with 2 assigned to 4 zones, and any time a sensor that's triggered activates the zone it's paired with lights up (RED-1,GREEN-2,BLUE-3,PURPLE-4). Choose a different ringtone for each sensor, so that when a sensor is set off, you can easily tell where the motion has taken place by the LED color or a specific ringtone. ie Set your entrance of your store to zone 1, and set backdoor to zone 2, if motion is detected at the back, the GREEN LED lights and sound goes off.
- WIRELESS PIR runs on 2* AA batteries (Not Included) for up to one year, portable receiver can be either plugged in using included AC adaptor or can run on 3* AA batteries (Not Included). Plugging in any standard outlet and using the batteries as a backup, even if there are no batteries in the receiver, it will retain the paring and alarm tone choices if unplugged or power fails. 1 sensor and 1 receiver are already pre-programmed so it is ready to work right out of the box.
- THE RECOMMEND POSITION is mounting the sensor 3-4ft above the ground at the entrance to your driveway and pointed straight out towards your house. The mounting plate has 2 screw holes for mounting, screwed it right to the fence post, tree, stake in ground and more. This will decrease or eliminate false alarms from small animals, and avoid unwanted alarms from nearby traffic. You can minimize the effect by selecting the detecting range and adjust the aiming angle to cover the desired area.

## Questions & Answers

**Q: How far does the wifi have to be ?**
A: Hey There!
The DW9 device does not need wifi to operate. The Receiver and the PIR Motion Sensor runs on FSK radio frequency technology, which can transmit signals 3 times longer than the ASK in traditional alarm systems. Once the PIR Sensor detect any heat movement, it will trigger the Receiver to chime. And the maximum distance between the Receiver and PIR Sensor is about 500ft in the open space.
Thanks for your interest in our products and your inquiry.

**Q: Does the dw9 have an alarm facility or just chime and how long does the alarm sound for?**
A: The product does alarm...it depends on how you set it up initially. The time of the chime plus melody and volume is also an option in the initial set up. It does come with instructions...but they are VERY basic...so it can be trial and error...but it's not difficult or time consuming. Unfortunately I would not recommend this product, as after only using it for about a month it developed a fault. The chime and alarm kept sounding even when there was nothing to set it off. We tried resetting, etc....nothing worked so it ended up in the refuse bin!!.

**Q: My pir is setting the alarm off constantly, I’ve tried clean as suggested, does it need resetting and if so how ?**
A: Hi friend,
Yes, please reset the product before re-pairing and ensure that the product has sufficient power.
Here we send the video about how to program and reset DW9 to you: https://youtu.be/WDjDSoIqgls 
Any problem, welcome to send us email on amazon, or here is our customer service contact information: fuers.csc01@outlook.com, we will help you solve it there.

**Q: Would this be able to detect my cat at my back door?**
A: I bought it for inside so.when the door opens the chime Iers me know someone has come In.

### ⭐⭐⭐⭐⭐ Brilliant
*by M***J on 21 June 2024*

This is our second one for a separate rear entrance. Works brilliantly and we know as soon as anyone enters the premises. The original one is still going strong on our front gate after two and half years. Rarely needs the batteries recharged and occasionally we get an unexpected alert when a bird uses it as a perch but can’t fault it. Really easy to set up and once it’s in place it works superbly.
