The Ideal Security SK602 wireless alert system utilizes a motion sensor to detect movement and sends a signal to the receiver, which can chime, sound an alarm (100dB), or activate lights. It's suitable for monitoring various areas like driveways, gates, and doors. The system offers versatility with four alert settings and can cover a range of up to 390 feet. While it's not pet immune, it provides options for both alarming intruders and gently indicating movement in restricted areas. For the elderly, this system enhances safety by alerting them to activity around their home, providing peace of mind and an added layer of security.
