Abstract: The present invention discloses a battery charge apparatus for a mobile phone, wherein the current output contact portions and the current input contact portions get in contact with each other in a comfortable and safe manner by magnetic force when charging.

Abstract: A security camera capable of preventing spiders by generating frequencies that pest or spiders detest, includes a key input part for inputting and setting condition of temperature and humidity and controlling ON/OFF operation, an ultrasonic wave generating part for generating ultrasonic waves and outputting the same via speakers, a humidity detecting part for controlling signals transmitted from a humidity sensor, a temperature detecting part for controlling signals transmitted from a temperature sensor, and a display part for displaying the generation of the ultrasonic waves, wherein a microprocessor drives the ultrasonic wave generating part to output the ultrasonic waves in the frequencies of 20,000˜50,000 Hz as the humidity detecting part and the temperature detecting part reach the set values thereof, thereby preventing spiders' webs around the security camera and obtaining clear images for a monitoring section.
