Description

[Technical Field]

[0001] The present invention combines a waterproof surveillance camera with a specific low-power radio transmitter-receiver. When the camera detects motion, it records an image in the camera body, while the transmitter transmits a specific low-power radio signal, and the receiver notifies of an abnormality via sound or light. The present invention provides such a surveillance camera system at low cost. [Background Art]

[0002] Conventionally, battery-powered outdoor security cameras with waterproof housing and recording functions have been widely sold to prevent theft of vegetables, materials, vehicles and the like. In order to extend battery life, many such surveillance cameras have a function of detecting human movement via an infrared sensor and recording images. However, there has been a problem that only checking recorded images after the occurrence of damage is possible, and there is no function to notify the owner when the damage occurs.

[0003] As an improvement measure, there is a method of displaying video on a monitor using WIFI or "BLUETOOTH" (registered trademark), but this results in high cost. Furthermore, it is sufficient to intimidate intruders at the site via sound or light and prevent theft damage before it occurs, without the need to check video. [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] The problem to be solved by the present invention is, as described above, to provide a low-cost solution that intimidates at the site where theft is occurring via sound or light, thereby preventing damage before it occurs. [Means for Solving the Problem]

[0005] The present invention is a surveillance camera comprising a motion sensor, and a motion detection output unit that detects a motion sensor signal and outputs the signal to a transmitter, wherein the surveillance camera starts photographing when detecting the motion sensor signal and transmits the signal to the transmitter,[ A control unit that receives and controls signals transmitted from the motion detection output unit of the camera body, The surveillance camera system is characterized by comprising a transmitter equipped with a transmitting circuit that emits low-power radio waves, a receiving circuit that receives low-power radio waves emitted from the transmitter, and a receiver equipped with a control unit that controls the signal from the receiving circuit and transmits it to an alarm unit that emits sound and light. [Effects of the Invention]

[0006] The surveillance camera of the present invention When the motion sensor detects movement, the transmitter emits a low-power radio signal, which is sent to a receiver that alerts the user to the anomaly with sound and light, while the camera itself begins recording. This allows for immediate notification of anomalies even in environments without internet access, and enables immediate deterrence at the scene of a theft. Furthermore, the captured images can be reviewed later, allowing for an accurate understanding of what happened. [Brief explanation of the drawing]

[0007] [Figure 1] Figure 1 is a diagram showing the configuration of the surveillance camera system. [Figure 2] Figure 2 is a block diagram of the surveillance camera system. [Modes for carrying out the invention] [Examples]

[0008] This invention is designed for outdoor installation, as it aims to notify the owner or deter intruders on-site if the camera detects an anomaly, even in locations without an internet connection. It is intended for use in fields, greenhouses, warehouses, parking lots, and similar locations.

[0009] Figure 1 is a block diagram of one embodiment of the present invention, in which the camera body 100 consists of a transmitter 200 equipped with a microphone for audio input, a motion sensor 10 for detecting movement, an amplifier 20 for amplifying the signal transmitted by the motion sensor, a motion sensor detection output unit 30, a memory for recording images, a power supply 40, a transmitting circuit 220 for transmitting low-power radio signals, a receiver 300 equipped with a circuit for receiving low-power radio signals, and an alarm unit 350 such as a speaker.

[0010] The motion sensor 10 uses, for example, a PIR type pyroelectric infrared sensor with λ = 5 to 30 μm. When the motion sensor detects movement, the amplifier 20 amplifies the signal and transmits it to the motion detection output unit 30 installed on the camera body 100.

[0011] The motion detection output unit transmits the signal amplified by the amplifier 20 from the motion sensor 10 to the transmitter 200.

[0012] The power supply 40 can be any DC power supply, such as a battery, AC adapter, or solar panel. In this invention, DC 5V is used. It is basically always in standby mode, but to prevent battery drain, a switching circuit sends a signal to the receiver only when a DC control signal is input.

[0013] Other aspects, such as the microphone, operation indicator LED, illuminance sensor, camera, and image recording method using recording media, are the same as existing technologies, so we will omit their explanation.

[0014] The transmitter 200 consists of a control unit 210 that receives and controls signals output from the motion detection output unit 30 of the camera body, a transmission circuit 220 that emits a low-power radio signal to the receiver, and a power supply 230.

[0015] The receiver 300 consists of a receiving circuit 310 that receives a specific low-power radio signal transmitted from the transmitting circuit 220 of the transmitter 200, a control unit 320 that controls the signal, an amplifier 330 that amplifies the signal, an alarm unit 350 that emits sound, and a power supply 340. Here, a chime is taken as an example of the sound output function.

[0016] The specified low-power radio as used herein refers to a communication means that can be operated without obtaining a radio station license pursuant to the Radio Law. For example, the transmitter 200 and the receiver 300 are wirelessly connected via a frequency of 300 MHz. Although approximate, wireless communication can be performed over a distance of about 300 m.

[0017] In the above-described first embodiment, when the motion sensor 10 transmits a signal, the camera body starts capturing an image, the transmitter 200 transmits a specified low-power radio wave, the receiver 300 receives the radio wave, and an alarm unit 350 (a chime is used in the present embodiment) sounds, whereby an abnormality can be immediately notified to the owner located at a place away from the site. Of course, since images are stored in the camera body, they can be checked at a later date.

[0018] It is also possible to install a plurality of receivers. If one receiver is installed around the site, an immediate threat can be achieved. On the other hand, if another receiver is installed near the owner, an abnormality can be immediately notified to the owner.

Examples

[0019] In the second embodiment, light is used as the alarm unit 350 of the receiver 300 to achieve a threatening effect. The camera body and the transmitter are the same as those in the first embodiment, so descriptions thereof are omitted.

[0020] When the receiver 300 receives the specified low-power radio wave from the transmitter 200, a receiving circuit 310 receives a signal, a signal is transmitted from a control unit 320 to the alarm unit 350, and a light source of the alarm unit 350 lights up.

[0021] For example, if a red rotating beacon is set to light up, the threatening effect at the site is high.

[0022] Of course, multiple receivers may be installed to notify the owner of any abnormalities. Furthermore, receivers that emit sound and light separately, or receivers that emit both sound and light, may also be used. [Industrial applicability]

[0023] As described above, the present invention is a surveillance camera system that can immediately notify the owner of any abnormalities and simultaneously take photographs, even in environments where the internet is unavailable. It can be used in agriculture, forestry, and for installation in private parking lots. [Explanation of symbols]
