    Why does my Takex Security System generate false alarms?
    • G
      gilbertjacobNov 1, 2025
      Your Takex Security System might generate alarms when no one is there for several reasons: * The power supply voltage might be unstable, so ensure it is appropriate. * Something might be moving within the detection area, or there could be sudden temperature changes; remove the object causing the issue. * There might be a source of electrical noise nearby, like a broadcasting station; consider changing the mounting location or removing the noise source. * Direct or reflected light, such as sunlight or headlights, might be shining on the sensor or into the detection area; adjust the mounting location or reflective item's position. * The sensor might be mounted at an angle; make sure it's level. * Cars or motorcycles might be detected at the edge of the detection area; reduce the...
