D3D Door/Window Sensors 433Mhz RF Frequency Model: Door_ZX-G12

Good and muat have product. With price range it comes offer best protection. The range of sensors are best even covering big and duplex house easily. Working on GSM sim and wifi as well. Built-in battery 🔋 is good. Sensors works immediately as per your settings and send sms as well as call on register mobile. Overall good experience. Thank you Amazon.

The Unit I received does exactly as mention its description. It's a system app and also pretty intuitive. This was my second purchase of this sensor after using previous ones I am very happy to go for another ones, it's easy to install if you go by its user manual very informative and simple steps even though if you are not familiar with these kind of products. Me too having some query regarding these products first time when i purchased it so I called to their customer care number their team guide me properly. In my opinion, you can go for these very real and good sensors at this price range

Purchased this sensor a few days ago and, having some difficulty while setting it up, I called the company support number. I must say, very prompt response to their technical team. Their executive is very friendly in nature. I have no knowledge about these sensors and their systems. Their team helped me each and every step over the phone and very patiently guided me through the whole procedure and gave me knowledge about the product and how to use it. Sensors are quite small and easy to hide if you don't want anyone else to find out. Response timing I must say I am impressed with the very prompt notifications I am getting. I love the feature that if any door/window gets opened, its system won't allow it to activate, which is a quite useful and important function in any alarm system All in all, its quite a good and trustworthy product!!

Don’t buy, it doesn’t have sound you want to buy another Product for your sound sensor Ordered waste of money. Now I want to buy their another kit. It cost around 6000. They didn’t mention properly. It only comes with two door sensor. Don’t come with a sound Very disappoint

Got this extra "door Sensor' for my G12 Alarm system a while ago from amazon got it at very reasonable price. quite small which is I think good to handle and fix it over window or Door, Its working very promptly and very sensitive I must say, when I tested many times and tried to open the window very fast still it worked without any lagging. Every time it gives me notification and siren. You can really go for this Sensor without getting 2'd thought.

It is working good for the past 3 years. I am looking for external WiFi alarm. Also what is the door sensor battery number? CRxxxx?

I would love to review this product. I must say, it's very easy to connect. You really don't need any technician or any other guy to install this one. I am also not a very technological person and am not well updated on new technologies. Still, I am able to install it on my own. And you really don't need to fix the door or window. It comes with double-sided tape, which is very helpful so that we don't have to arrange this tape in your home. Range-wise, I must say, impressive. I can't complain Easy to install. Good Build Ouality.

The door switch does not work for a vertical distance of 15 feet with wall and ceiling in between. There is no specification for the product. One has to install by trial and error
