Abstract

A door monitor with a portable storage medium includes a host module disposed behind the door, a night-vision camera module disposed outside the door and electrically connected with the host module, a sensor disposed outside the door for detecting whether any object is approaching, and a microphone connected with the host module. The host module has a multimedia processor, a display, a touch panel, and a portable storage medium connecting interface. The user enters monitoring criteria using the touch panel. When an object approaches and stays for a period of time, the night-vision camera module starts recording. The recorded video data are sent to and played on the display. The video data are compressed in a format and stored on the portable storage medium. The door monitor readily monitors situations outside the door and records and stores video images for the purposes of home security.

Claims

1. A security door monitor having a portable storage medium, comprising:

a night-vision camera module mounted outside a door for capturing images outside the door;

a microphone for capturing sounds outside the door;

a sensor for detecting whether any object is approaching the door from outside; and

a host module mounted behind the door and in signal communications with the night-vision camera module, the microphone, and the sensor having

a box;

a touch-control liquid crystal display (LCD) disposed outside the case;

a portable storage medium connecting interface provided on the case; and

a multimedia processor mounted in the box to connect to the touch-control LCD, the microphone, the sensor, and the portable storage medium connecting interface.

2. A door monitor having a portable storage medium as in claim 1, wherein the night-vision camera module has a frame, a plurality of infrared (IR) light-emitting diodes (LED'"'"'s) mounted around the frame for night-vision illumination, and an image capturer mounted inside the frame.

3. A door monitor having a portable storage medium as in claim 2, wherein the image capturer is a CCD or CMOS image sensor.

4. A door monitor having a portable storage medium as in claim 1, wherein the multimedia processor is further connected with a digital-analog (D/A) converter for converting compressed digital monitoring image data into analog data and sending the analog data to a television or community security monitoring system.

5. A door monitor having a portable storage medium as in claim 1, wherein the multimedia processor is further connected with a high-definition multimedia interface (HDMI).

6. A door monitor having a portable storage medium as in claim 1, wherein the sensor is a passive infrared (PIR) sensor.

7. A door monitor having a portable storage medium as in claim 1, wherein the portable storage medium connecting interface is a memory card connector and the portable storage medium is a memory card.

8. A door monitor having a portable storage medium as in claim 1, wherein the image compression format of the multimedia processor is MPEG-4.

9. A door monitor having a portable storage medium as in claim 1, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

10. A door monitor having a portable storage medium as in claim 2, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

11. A door monitor having a portable storage medium as in claim 3, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

12. A door monitor having a portable storage medium as in claim 4, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

13. A door monitor having a portable storage medium as in claim 5, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

14. A door monitor having a portable storage medium as in claim 6, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

15. A door monitor having a portable storage medium as in claim 7, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

16. A door monitor having a portable storage medium as in claim 8, wherein the host module has a power supplying unit for providing a DC working voltage and built in with a high-capacity rechargeable battery.

17. A door monitor having a portable storage medium as in claim 4, wherein the multimedia processor is further connected with a digital-analog (D/A) converter for converting compressed digital monitoring image data into analog data and sending the analog data to a television or community security monitoring system;

and a high-definition multimedia interface (HDMI);

wherein the portable storage medium connecting interface is a memory card connector and the portable storage medium is a memory card.
