The high speed dome is the most sophisticated camera front end of the surveillance system and has the best overall performance. It is complex to manufacture and expensive, and can adapt to high density and most complex monitoring occasions.
High Speed ​​Ball Features
The high-speed ball has several basic functions. The first is the fast operation speed, the second is the smooth operation, and the third is the accurate positioning.
1. High-speed function: Preset position speed is required to emphasize fast, basically reaching over 250 degrees/second; the second manual speed emphasizes smoothness, the control is sensitive and flexible, can not be too fast, can't be stiff, and supports variable speed.
2. Preset function: It must have more than 64 preset positions. At the same time, the preset position must be accurate. The preset position can also be memorized after power off.
3, cruise scan: must be able to set the high-speed ball can cruise scan function between the various preset positions.
Speedball has some advanced features: 1. Trajectory memory function: It is required that the high-speed ball can store multiple arbitrary trajectory routes, and at the same time, the trajectory path can be invoked through settings.
2. Menu display function: It can display a complete operation menu, through the menu to modify the operating speed, preset dwell time, operating mode, etc., through the menu can modify the camera parameters, and programming, automatic tracking, privacy shielding Other functions.
3, comes with alarm input and output: an alarm input and output module is added to the high-speed ball.
4, network high-speed ball, fiber optic high-speed ball: In the high-speed ball and then integrated network video server module or optical module.
Dome camera installation troubleshooting 1. The ball machine power no action, no image, the indicator light does not shine Check the power cord is connected to the wrong: If the wrong connection, please follow the correct method to connect the power cord. Check whether the power supply is damaged: If the power supply is damaged, replace it to ensure that the power supply is not damaged. Check if the fuse is damaged: If it is damaged, replace it to ensure that the fuse is not damaged. Check the power cord for poor contact: If it does not contact properly, reconnect the power cord or replace the power cord.
2. There is a self-test on the power-on, there is an image, and it is not possible to check whether the address and baud rate of the dome camera are set. If there is any error, set the matching address code and baud rate. Check whether the protocol settings are correct: If yes, set the corresponding protocol. Check whether the RS485 control line is connected correctly: If there is any error, please connect according to the correct method.
3. The self-test cannot be performed. There is an image but there is a noise test. Check for mechanical failure. Please correct the internal mechanical structure of the dome camera. If the camera is tilted, please correct it. The power may not be enough: Please replace the power supply that meets the requirements and try to place the switching power supply near the dome.
4. The image is unstable. Replace the qualified video cable and check if the video cable is in poor contact. The power may not be enough: Please replace the power supply that meets the requirements, and place the switching power supply near the dome.
5. The blurring of the picture may focus on the manual state, control the dome camera or call any preset position, and the dome camera can resume auto focus. The transparent cover is dirty and the transparent cover is cleaned.
6. Do not stop or delay the dome control to check if the ball machine's matching resistance is added at the farthest point. If the distance from the control dome is not added, please add a matching resistor. The power may not be enough: Please replace the power supply that meets the requirements, and place the switching power supply near the dome.
