D3D Wireless Smart Home Security System | Motion Detection Sensor | Door Security Sensor | WiFi and GSM Dual Protection Intruder Alarm System |Model ZX-G12 (Black)

Very good and useful..

I was looking for a home security system with Mobile App control features for a reasonable price and came across D3D on Amazon. The installation of the product is fairly easy, but don't fix anything until you watch the DIY YouTube video suggested in the product manual . It requires a SIM card which will enable a feature that connects a call to your mobile incase of a break-in . The app is also easy to use and can be connected to Alexa where you can avail the voice command features. The product comes with one motion sensor and 1 door sensor, you need to buy extra sensors separately if you need more. Connecting the devices to the main control system was super easy. I would recommend this product for its price, reliability and easy to use features.

One more thing I noticed after complete installation..... The Door Sensors have been provided with a double side tape which needs to be stuck to the Door Frame/ Door. This double side tape is of Medium Quality and can fall off due to Sunlight falling directly on door and heating up the door or wind/ dust blowing in from cracks of the door. It may trigger a false alarm. Well it has not fallen off for me till now. However I would recommend you to be aware and not panic if you get a false alarm, when the house is armed. Alternatively you can buy a 3M VHB Double side tape and stick it. But be careful while installing, once it (3M-VHB) is stuck you cannot remove it by ordinary means. I am changing my review. (In Cons section, I am sharing my experience, but read the Pro's also). Cons: At first it looks pretty difficult to set it up. 1. The SIM Card which needs to be put is a full size SIM Card (Don't break the SIM into smaller parts). Nano SIM and Mid Size Sim will not work. By chance if you insert smaller SIM in the slot, it will not come out. 2. When you insert the SIM in slot by force of your finger, it will spring out and stand. The way they show in the installation video, it is not that easy. Solution is to take the full size SIM, push it firm by a flat plastic and the SIM will click in. It works by it is tricky. It took me 2 days to learn it as the instrument loos delicate. I was about to return the product, finally I learnt it. 3. You need to be a little bit of Geek person, else you will struggle a bit. Just follow the steps in "Quick Start Guide" given in the box and you will be successful. Do one step at a time. 4. Spare REMOTE is not available on order. Only 2 REMOTE's are provided with the Product. If you loose one of them or if you spoil one of them, life will be difficult. 5. Engineer will not be available onsite in your city. Support is by phone and WA. But it is OK, this is not a major problem. You can set it up on your own. Why pay for the person to install. Pro: 1. This is exactly the device what you want for your Apartment/ Bungalow. It works on Wifi and SIM Card. 2. When armed it checks all your doors are shut, if someone gains access and walks in your house the PIR Sensor will alert you over mobile phone. 3. You can arm and disarm your house from your mobile phone, when you are away. Another alternative is having a Video Camera is good, but do you think you will see the entire day recording everyday when you come back home. It is not practical.

Very very useless product. Motion sensors with even car lights activate the system and siren. Even small things like insects, birds or animals activate the siren and keep you unnecessary awake throughout the night. Extra siren is totally useless and have bug. Many times even after disarming the system, siren keep on buzzing till you dont switch off from mains. I will not recommend motion sensors and siren with this system. Only door magnets are fine.

Using since 1 year for home security. Must have device. Very responsive, immediately initiates alarm on intrusion. Battery life of motion sensor is excellent, working since 1 year without need to change it.

My best investment

Great product. It has all the features. Although it's a Chinese product, it has so many features and ticks all the boxes. Cheap and best home security option.. Initially thought of going for Yale or Godrej, but decided to try this... Setup is super simple, works well with app. Pro: Easy setup Simple device operation. Works correctly without errors Zigbee radio communication, better than wifi comm 3M stickers Cost effective Automatically disarm arm turn on any timing SMS call facilities available (need SIM) APP interface is very good, excellent and responsive. Sensors came pre configured on the box which was very convent. App has many other features. Easy to install, self installation. 2 remotes are very useful It has many taper proofing techniques so if the if try to dismantle it, they can't. The technology is very good, if door open anyway surely alarm will get set off. Excellent product and good build quality. Very responsive and nice I don't know how many years it will work without errors, let's see Only disadvantage is that audio volume is low, and doesn't have extra alarm as accessory. Otherwise Evrything else is there. Other issue I had was sometimes remote click was not responding but it worked after clicking remote 2nd time.

A simple & effective home alarm system. Easy to install and operate. Gives you multiple ways to set & disarm the alarm. An app allows remote control of the system. I found it easy to install and set-up. The installation & setup guide could be a little more elaborate & in simple language for those not technically inclined. Of course, there is an YouTube video that helps.
