Dome-shaped surveillance camera / dome cover for removing rainwater and dust.

Abstract

Removes rainwater and dust from the dome cover of dome-type surveillance cameras, and reduces wasted power by utilizing sensors. [Solution] A soft felt pad (with a magnet) is attached to the back of the dome shutter, and when the dome shutter is opened or closed, the felt pad comes into contact with the surface of the dome cover, removing rainwater and dust. The magnetic felt pad makes replacement easy. Furthermore, dome shutters for use in extremely cold regions have a heater built into the felt pad.

Description

[Technical Field]

[0001] [Background technology]

[0002] Dome-type surveillance cameras are installed both indoors and outdoors. Indoors, they are typically installed on ceilings and interior walls, while outdoors they are installed on exterior walls or poles. However, rainwater and dust can adhere to the dome cover, making it necessary to maintain the monitor's clarity. One method is to use a cleaning nozzle to remove dirt from the dome cover with a cleaning solution, but this method is avoided due to the high cost of the cleaning solution. [Prior art documents]

[0003] Patent Publication No. 2022-053153 Means for solving the problem

[0004] Valeo of France will begin mass-producing a device in 2026 that will use centrifugal force to spin the dome cover at high speeds of approximately 10,000 rpm to blow away dirt from the dome cover caused by water droplets, snow, mud, salt water, insects, bird droppings, etc., as a measure to reduce the amount of cleaning fluid used.

[0005] Dome-type surveillance cameras must be highly durable in both hot and cold temperatures and have high performance that allows them to be installed both indoors and outdoors.

[0006] Regardless of whether they are used to monitor suspicious individuals, cameras need to be set up to be inconspicuous in order to reduce the sense of intimidation felt by ordinary people.

[0007] In today's society, where crime prevention measures are becoming increasingly important, the introduction of surveillance cameras is essential.

[0008] The biggest feature of dome surveillance cameras is that they cover a 360-degree field of view and can track moving objects. The camera automatically scans in all directions to provide a wide view.

[0009] Pallet-type (cylindrical) cameras are excellent for long-distance monitoring and are equipped with zoom and infrared functions, making them suitable for nighttime monitoring. PTZ allows for Pan (horizontal rotation), Tilt (vertical tilt), and Zoom (magnification) operations. Box-type cameras have a smaller monitoring area than dome surveillance cameras.

[0010] The biggest feature of dome-type surveillance cameras is that they minimize blind spots and allow a single camera to monitor a wide area.

[0011] To get the most out of your surveillance cameras, you must pay close attention to maintenance. If the monitor image is unclear, the surveillance camera cannot be used effectively. It is essential to take measures to prevent the dome cover from deteriorating due to rainwater and dust.

[0012] The purpose of this application is to remove rainwater and dust from the dome cover and reduce power consumption by utilizing sensors.

[0013] Maintenance is essential for a surveillance camera to withstand the harsh environments of rain, dust, and extreme temperatures. On windy and rainy days, the dome cover must be repeatedly cleaned of rainwater and dust.

[0014] The retractable lens shutter is made up of 16 to 20 folding blades, or a sufficient number if necessary, and covers the entire dome cover, making it possible to protect against rainwater and dust.

[0015] Dome surveillance cameras do not need to be operated 24 hours a day; it is enough to make the most of the sensor function and open and close the dome shutter as needed.

[0016] A soft felt pad (with a magnet) is attached to the back of the dome shutter, and when the dome shutter is opened or closed, the felt pad comes into contact with the surface of the dome cover, removing rainwater and dust. The magnetic felt pad makes replacement easy. In addition, dome shutters for use in extremely cold regions have a heater built into the felt pad.

[0017] Operating surveillance cameras indefinitely results in unnecessary power consumption. Infrared motion sensors have motion detection functions, so using them in conjunction with other sensors can save power. Ultrasonic sensors take advantage of the property of ultrasonic waves reflecting off objects. Active sensors detect infrared rays emitted by objects. Passive sensors can be installed outdoors and are attached to ceilings, exterior walls, poles, etc. Motion sensors are also used in lighting for entrances, parking lots, hallways, and staircases, and are used everywhere, including automatic doors and automatic flushing systems. Dome-type surveillance cameras can also save power by utilizing their sensor functions. [Brief explanation of the drawings]
