Carbon monoxide sensor

Reacts to toxic carbon monoxide as well as changes in temperature. In order to prevent carbon monoxide poisoning, the sensor must be installed below the level of the edge of the bed so that it can react before the carbon monoxide is inhaled by the sleeping person.

Flood sensor

Detects wetting of the floor and sounds an alarm signal and issues a notice before the water can cause irreparable damage. The sensor can be installed in the kitchen or bathroom, for example.

Smoke surveillance

Smoke surveillance is the simplest option for ensuring the security of one’s loved ones. Smoke and/or carbon monoxide sensors send a signal to your phone or to the USS control centre as well. You can use webcam images to decide whether or not the alarm was caused by actual fire hazard and send a patrol car to investigate, if necessary.

  • Stylishly designed, wireless, and easy-to-install smoke alarm, carbon monoxide alarm, or both devices
  • Possibility to add a webcam for detecting the reason for the alarm
  • Possibility to add a flood sensor


A fire involving your loved ones or at your home is the most horrible thing that can happen. Using smoke and carbon monoxide sensors in Estonian homes is compulsory and they have saved many lives. There is a problem with these sensors, though, they sound an alarm, but it is not transmitted to the home owner or security company.

Smoke surveillance is the easiest way for making your home more secure. It provides a constant overview of what is happening in your home even when you are away and, in the event of an accident, you can immediately respond from a distance.
