Definitions

  • the present invention relates to a case for concealing and storing a monitoring television camera, in particular, a color camera.
  • a monitoring power camera there has been a monochromatic camera stored in a colored translucent dome-shaped cover so that it cannot be seen from the outside.
  • a high-resolution monochromatic camera is constructed using a CCD solid-state image sensor as the camera, and simultaneous monitoring is performed using a monitor television, and burn-in and distortion are generated with low residual images. Images can be obtained.
  • the monitoring force camera as described above uses a colored cover, there is an inconvenience that even if the color camera is stored, the primary colors cannot be reproduced due to the filtering action of the power camera. Conversely, if the force bar is made colorless and transparent, there is a disadvantage that the inside can be seen as described above.
  • An object of the present invention is to provide a case for a surveillance power camera capable of solving the above-mentioned problems and concealing and storing a camera.
  • the present invention provides a base, and a cover made of transparent plastic for concealing a color camera mounted on the base, and on a front surface or a back surface of the cover, It comprises a case for a surveillance power meter that has a relatively transparent half-mirror film made of spatter, nigergel and iron formed by the sputter method.
  • the cover covering the front of the camera is a half mirror and is colorless and translucent, it can be used for the CCD solid-state imaging device in the camera. Indicates the color of the subject as it is.
  • the reduction in incident light halo due to the half mirror is sufficiently ensured by the high sensitivity of the CCD solid-state imaging device and the function of the video processing circuit, and a monitoring image with excellent image quality and reproducibility can be obtained.
  • FIG. 1 is a partially broken side view showing a camera case in an embodiment J of the present invention.
  • FIG. 2 is a schematic diagram showing a connection relationship between the camera case of FIG. 1, a power supply, and a monitor television.
  • FIG. 1 is a partially broken side view showing the structure of the force lens case in the embodiment.
  • reference numeral 1 denotes a base installed on a wall surface or a ceiling surface in this case, and has a circular shape formed of a suitable plastic material.
  • 2 is a dome-shaped force par attached to the surface of the base 1 (the lower end in the case of a ceiling-mounted type).
  • the main body is made of, for example, acrylic resin. Made of transparent plastic.
  • the force par 2 is arranged concentrically so that the circular opening is located slightly inside the periphery of the base 1 and completely conceals the force camera 3 installed on the surface of the base.
  • the tip 3a of the camera 3 faces the lower left of the figure at the reference position, but adjusts the angle appropriately to see the intruder's face in the set position range You can do it.
  • a half mirror film 4 is coated on the inner surface of the force par 2.
  • the half-mirror film uses a cathode made of, for example, an alloy of chromium, Nigger, and iron, and supports the power member 2 on the anode facing the cathode to scatter the above-described cathode material, thereby covering the cover. It is deposited on one inner surface to form a plating layer.
  • the inside of a sputtering mechanism (not shown) in which such an electrode structure is arranged is, for example, a vacuum degree of 2 to 5 ⁇ 10 2 torr. It is maintained and a voltage of several thousand volts is applied between both electrodes.
  • the details of the sputtering method are appropriately selected according to the transparency, thickness and the like required for the half mirror film 4.
  • the camera case of the present invention in which the force par 2 having the half-mirror film thus formed is mounted on the base 1, has an appearance effect of a kind of interior decoration as a dome-shaped mirror. With sufficient power, it can function as a case for the camera.
  • Fig. 2 is a schematic diagram showing the connection relationship between the monitoring power camera case of the present invention, the monitor television 5 and the camera power supply 6, and the power supply 6 is connected to the camera built into the case. 7, the video signal from the camera's CCD solid-state imaging device is transmitted to the monitor television 5 via the coaxial cable 8, and the power captured by the monitor television 5 is transmitted to the monitor television 5. The first image is displayed.
  • a decorative power monitoring power lens that does not make the attendees aware of the power camera.
