Smart homes can include motion and various opening sensors, such as door and window opening. After all, this makes it easy to create thousands of other things, such as motion-sensing lighting, or to turn off the heating if you are ventilating in the winter. The BlitzWolf BW-IS22 provides a very good basis for this, as it is also a kind of gateway and alarm, as well as a Tuya smart home, so it can work with countless other sensors and devices. But anyway, it is a doubly secure, GSM + wifi smart alarm and can be used with an application. Its advantage is that it can be used in case of power failure due to its own battery, plus it can even be connected to an external battery, so it can work until the end of time, even if there is no power, no wifi (because it also alarms in GSM mode).
he main panel also includes a speaker, so it alerts you very loudly with the selected sound if necessary, and since it also has a microphone, it makes a normal phone call.
Its built-in battery provides power when needed and notifies you in the event of a power outage. The big advantage, however, is that it can be powered by a standard micro USB cable with 5V, so an external battery can be connected to the power supply and a larger (eg 20,000 mAh) battery can run for a very long time.
By comparison, the built-in battery has a capacity of only 500mAh, which is approx. Operates for 3 hours. Now if 12,000 mAh can be extracted from the 20,000 mAh capacity, it gives an extra 24x as long operation time, i.e. 24 x 3 = 72 hours, which is 3 days.
Also, since it can alarm without wifi, so it can be completely independent, it forms an unavoidable alarm system (with a GSM blocker, of course, it can be an obstacle to the alarm, but where there is a risk, a simple alarm is not the solution).
A total of 99 sensors can be used, which can be motion, door / window opening, smoke, gas, carbon monoxide, water, etc. At standard 433MHz, the sensors communicate with the panel, making it compatible with solutions from other manufacturers. It comes standard with 1 door / window opening sensor and 1 remote control.
The window / door opening sensor consists of two parts, one part is placed on the door, window, the other on the frame (but you can also go to the cabinet, drawer).
There is also a remote control in the package, with which the alarm can be switched on / off and an alarm can be triggered in case of an emergency (expandable up to 10 pieces).
It can be used as a GSM-based alarm, in which case a SIM card must be inserted. In this mode, it alerts you with an SMS or call (pre-recorded speech that is being played). It can also be switched on and off remotely and timed.
But it can also be used with a mobile application (Android, iOS) and in this case it displays a message on the phone in case of an alarm.
When motion is detected, it can also alarm at the set volume (but can also be turned off, in which case it is a silent alarm).
It can be used completely without installation, as the main panel can be placed on its back and the opening sensor only needs to be glued (it is equipped with double-sided glue at the factory).
Because it is Tuya-based, it can be connected to many other Tuya-based devices and various operations can be performed along some logic (if something happens> something happens). The remote control also has an SOS function, which you can press to dial a number or send an SMS.
Obviously 1 door / window opening sensor is not enough for everyone, so it can be expanded. It uses the standard 433MHz and is typically used with such sensors. Here you will find a list of motion sensors and here is a list of opening sensors.
Motion sensors of BlitzWolf BW-IS22 also do not require installation because they are battery-operated and can only be placed somewhere (but can also be mounted on a wall in general).
