JC 433MHz Security Wireless DIY Standalone Alarm Siren Kit Multi-Function Alarm Host with PIR Detector, Door Window Sensor, Remote Controller, Water Leakage Sensor and Warning Sticker

Works great synchronised with full kit and external siren and surprisingly easy to set up, had 3 different types of this sort of kit but definitely the best so far and looks like a very expensive system when installed. Great product thanks

simple install worse you learn how to marry components to the control box. Alarm is quite loud and may scare an intruder but unlikely to bring anyone down the street to investigate (perhaps someone next door might hear)came with a movement detector to cover one room and two contact switches that can cove two doors or windows.worth the money giving some piece of mind. blue light flashes on main unit which is also the alarm. seems to do what it says so i bought a second one

Initially a little difficult to set up following just the instructions, the You-Tube video is a great help, you have to link each trigger with the hub by turning on a trigger and the hub, press the little "set" button on the round hub until it makes a bleep then operate the trigger, say the motion detector, you move you hand across is whilst the hub flashes really quickly a couple of times, gives 3 bleeps, then they are linking, you have to do that with every item including the fob. I like the way you can have a window open, set the alarm, and the alarm will still cover the rest of the triggers even though that particular window doesnt have the contacts touching.

Works very well, and good value for money when compared to purchasing the siren only.

Very nice product

Alarm was great for 1 year. Worked as should, not the loudest but enough for the garage i used it on. Now the round sounder unit functions but has gone very quiet and crackles. Shame it hasnt lasted long, would have hoped to get at least a few years from it.

I purchased alongside the "JC Wireless GSM & WIFI Security Alarm System, Home and Business RFID Burglar Security, Support Auto Dial, Multi-language GUI and English APP Control , with Pet-friendly PIR Detector, Door Window Sensor,Remote Controller, RFID Tag, and Warning Sticker". It is a great piece of kit but I ordered it thinking it would work with the above alarm system as it did not come with a siren, and I assumed the siren could be mounted outside. It is for indoor use, don't get the reason for it being inside but never mind. So not negative about the product, just my miss-understanding.It can be used as a standalone system, might be good for a flat, shed, garage or something like it.It looks modern, I used the door sensors and sensor with the above alarm system and it all worked well, was simple to pair.Great customer service.

Everything works. Works as wireless siren with Digoo dg-hama 3g. Also managed to get it to work standalone, great value.

I bought this basically only to have a siren that I could trigger from home assistant. Its great for that, you can send a 433 MHz code to trigger the alert (which is surprisingly loud given its small size), and another code to make it stop. Perfect. Its usb powered, but has a built-in battery so it will work even without power.The rest of the kit; the PIR sensor is quite good actually. Small and discreet but seems to work. The red LED is subtle and can be disabled with a jumper. its so light weight you can easily mount it with some double sized mounting foam. Battery life (2xAAA) remains unknown, but I like them enough that Im going to order more of these separately.The door sensors have separate codes for open and close. Thumbs up. They do use those rather hard to find 12v batteries.I tested the moisture sensor with a sponge, and it worked perfectly. It has one code for wet, one code when it becomes dry, and there is a button built in the transmitter which sends a third code for some reason. To cancel an alarm?For 50 euros, this set is a complete steal. It would actually work as a budget alarm if its all you have. Add a ~10 euro sonoff RF/wifi bridge and you should be able to make it "smart" and get alerts on your phone.But its not flawless; the siren looks like a cheap child toy. IM not sure why they chose a weird blueish color for the led effects. And the USB adapter it came with had a UK plug.

KIT interessante che può essere usato sia da solo, in quanto la sirena funge anche da piccola centrale autonoma, sia in abbinamento al kit (https://www.amazon.it/gp/product/B0796VKWS4/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) che lo completa.Usata da sola questa sirena viene abbinata sia ai telecomandi per attivare/disattivare sia ai sensori a infrarossi e comunque a tutti gli altri sensori compatibili, e ce ne sono veramente molti. Credo che acquisterò altre sirene per dislocarle in più punti della casa.

La verdad me ha sorprendido lo alto que suena la sirena. Perfecta para ponerla en otro lugar de la casa e incrementar la potencia del sonido. Es inalámbrica, no va conectada directamente al panel pero si a la corriente. El resto de elementos muy bien. Ahora me falta probar la sirena exterior.

Hay alguna manera de poder conectar o desconectar la alarma sin el mando a distancia?Solo permite la activación con mando o hay alguna manera de hacerlo sin mandos.

No es fácil de instalar
