Description

A security camera with anti-blocking function

technical field

The utility model relates to the technical field of security cameras, in particular to a security camera with an anti-blocking function.

Background technique

Cameras can be divided into two categories: digital cameras and analog cameras. Digital cameras can convert analog video signals generated by video capture equipment into digital signals, which can then be stored in a computer. The video signal captured by the analog camera must be converted into a digital mode by a specific video capture card and compressed before it can be converted to a computer for use. Digital cameras can capture images directly, and then transmit them to a computer through a serial, parallel or USB interface. The cameras in the computer market are basically digital cameras, and the digital cameras are mainly USB digital cameras using new data transmission interfaces. Most of the products on the market are such products. In addition to this, there is a product that works with video capture cards, but it is not mainstream yet. Due to the rapid popularization of personal computers, the overall cost of analog cameras is relatively high, and they cannot meet the BSV LCD splicing screen interface and other reasons. The transmission speed of the USB interface is much higher than the speed of the serial port and parallel port. The analog camera can be used with a video capture card or a USB video capture card, which is very convenient to connect with a computer. The typical application is general video surveillance. Clean area camera, clean area embedded special camera is a special camera for real-time monitoring of key positions of important equipment in clean room in clean area. The camera is a pure flat panel, embedded in the color steel plate installation, zero sanitary dead angle, easy to clean, easy to install, fast multi-point control, compatible with mainstream video systems, webcams generally have basic functions such as video camera/communication and still image capture, etc. After the image is captured by the lens, the image is processed by the photosensitive component circuit and control component in the camera and converted into a digital signal that can be recognized by the computer, and then input to the computer through the parallel port or USB connection, and then processed by the software. Image restoration.

However, in the existing camera, dust will inevitably fall on the surface of the lens after long-term use. If it is not wiped, it will have a great impact on image acquisition, and the camera has no protective device, which is easily blocked by criminals.
