Patent Images
1. A security device mounted on a door having a through hole comprising:
- a lens;
a fastening means provided in front of the lens for fastening the lens on a first opening of the hole of the door;
a telescopic tube inserted into a second opening of the hole of the door to be secured to the fastening means;
a complementary metal oxide semiconductor (CMOS) based image sensor provided on the second opening of the hole aligned with the lens for sensing image through the lens for converting into image signals;
an image processor circuit provided in a rear of the CMOS based image sensor being secured to the CMOS based image sensor for processing image signals sent from the image sensor;
a liquid crystal display (LCD) provided in a rear of the image processor circuit being fixed and secured to a back of the door for converting the processed image signals into an image and displaying the image; and
a power source for powering the image processor circuit, the LCD, and the CMOS based image sensor.

Abstract
A door security device mounted on a door having a hole comprises a lens mounted on a fitting, a telescopic tube inserted into the hole secured to the fitting on front of door, a complementary metal oxide semiconductor (CMOS) based image sensor in the rear end of hole for sensing image through lens for converting into image signals, an image processor for processing image signals sent from image sensor, and a liquid crystal display (LCD) for showing the image. With this, advantages such as high safety, low power consumption, adaptability, easy assembly, compact, flexibility, and no damage to door by using existing door hole can be effected.
