  Analysis on Four Advantages of High - Definition PTZ Camera

  Dome camera (PTZ Dome) is an integrated dome camera with fast running speed, optical zoom, precise positioning and flexible control. It has been widely used in safe city, airport, rail transportation, electric power, education and industry. And other industries. With the entire monitoring industry digital, network, high-definition development process, network PTZ camera in product development has also entered a new stage.

  Power over Ethernet

  ALL IN ONE, that is, a network cable to achieve all the data transmission, is an important advantage of network monitoring. Ethernet power supply IEEE 802.3af (48V DC at the POE switch, maximum power 15.4W) is only suitable for powering the fixed network camera and the fixed dome camera.

  High PoE, 802.3at supports 50-57V DC in the voltage range, 53VDC scale, 30W maximum power support. Fully available to the dome camera and its shield power supply. Through the High PoE, the network dome does not need any video lines, audio lines, control lines, power lines, etc., just link a cable, you can achieve the cable connection.

  In order to shorten the network HD PTZ camera installation time, and better guarantee the installation of fast ball quality, more network PTZ camera, especially outdoor HD PTZ camera at the factory, it has been configured IP66 shield, pre-installed Of the bracket, that is, out of the box (Out-of-the-box).

  High PoE with Out-of-the-box, you can quickly install the network fast ball, and can fully guarantee the quality of installation.

  Automatic flip structure

  PTZ dome camera according to its different mechanical structure, can be divided into high-speed dome and PTZ camera two types, two types collectively referred to as PTZ dome camera.

  High speed ball with shaft drive, robust structure, to achieve 360 degrees of continuous rotation, but the higher cost. The PTZ camera with gear drive, due to the existence of limit, can not achieve 360 degrees rotation, but the cost is low. And can achieve 360 degree rotation, but also to ensure lower manufacturing costs. That is: 360 degrees automatically flip PTZ camera, this technology is also used in high-definition PTZ camera.

  This kind of spherical camera with the same PTZ camera, the use of gear transmission, but also limited. When the camera is rotated 360 degrees horizontally, the camera will rotate 180 degrees horizontally in 0.1 second and 180 degrees in the vertical direction after reaching the limit. After the limit is reached, the camera will continue to rotate in the direction controlled by the person , Thus achieving a 360 degree continuous rotation.

  In the case of the camera does not require a long continuous rotation, both want to achieve 360-degree monitoring, but also hope that the low ball price is low, this automatic transfer structure of the camera is a very good choice. Under normal circumstances, this automatic flip structure of the dome camera, the horizontal rotation speed and vertical selection speed can reach 300 degrees / second speed, and according to the zoom situation, automatically adjust the rotation speed, so as to ensure the precise speed limit The

  More flexible control

  HD PTZ camera technology development, making the monitoring application needs to further improve. In particular, based on networked camera control and operation, requires high-definition PTZ network camera can quickly respond to control commands, and to achieve the camera rotation and zoom.

  Normally, the HD PTZ camera has two main control modes: joystick control and center point control. When using the remote bar to PTZ control of the camera, it is difficult to achieve accurate positioning, control difficulties. But through the "center point control" mode, can completely solve the problem.

  "Center point control" mode, the mouse in the image shows a bit "+" icon, in the monitoring image, where the mouse point, the camera will be the center of the point, automatically rotate, pinpoint to the point. When you want to enlarge a target, you can press the left button while dragging the mouse, frame the target, you can achieve the target of the automatic level, vertical positioning and amplification.

  "Center point control" mode, only suitable for mouse control, not suitable for remote control.

  Local storage

  By supporting up to 32GB of local storage in the camera's built-in SD / SDHC card slot.

  As a result of the use of H.264 encoding format, 720P format, 32GB SD card, can still be stored for 2 days.

  SD card storage, more for storage based on different events, when the camera is blocked, event alarm, network interruption, etc. video, and support the event of pre-video, so as to ensure the integrity of the event video.

  When the network is restored, the SD recording is imported into the centralized storage by manual or automatic mode.

  Local storage as a centralized storage of backup and supplement, can further ensure the reliability of monitoring.
