1. Housing / shroud / body
Most of the ball machines need to be used outdoors, so waterproof and dustproof are very important. Generally, the main body of the ball machine is made of metal, and the sealing is very good. The IP protection level can reach IP65 and IP66. The transparent cover of the lens and infrared is generally made of acrylic material to ensure good light transmission while ensuring hardness.
The ball machine generally uses two mounting methods, hoisting and wall mounting, and needs to be used with the corresponding mounting bracket.
2. Infrared light / infrared light control board
PTZ generally use high-power IR lamps such as dot matrix, laser, OSRAM or laser.
In order to match different magnifications of the lens, the low beam, high beam. When the lens magnification changes, turn on the different lights so that the illumination angle and distance of the infrared light match the lens. Some can also dynamically adjust the power of the infrared light to achieve better night vision.
3. Movement (lens module / network coding board / interface board)
The lens can be selected with different zoom ratios as needed. For example, 18 times, 20 times, etc.
Like the ordinary IPC, the core part of the network coding board of the movement is also composed of DSP+sensor. The original signal output of the movement is typically output via a 30-pin LVDS interface (SONY EH6300 calibre) or a 36-pin YUV interface (Hitachi SC110 calibre). Then access to the network code board for encoding compression.
4. Motor motor (slip ring / limit)
The PTZ Camera can be rotated up and down/left and right, and there are two stepping motors respectively. The ball machine rotates 360°, and the camera needs to access the external tail wire. At this time, the outer tail wire needs to be introduced by means of the slip ring. Some domes consider adding a limit switch to the rotating pan/tilt. Some limit switches are physical switches and some are controlled on a single program.
5. PTZ decoder board
Control the PTZ motor to rotate, preset points, cruise and other functions, you need to use the decoder board. Including the address code of the PTZ device, the protocol, the baud rate, the PTZ control parameters in the network coding version and the matching of these three parameters, the PTZ can be controlled through the network. (The movement zoom does not need to go through the decoder board.)
6. Power Board
Power the PTZ camera and take into account certain anti-surge functions.
7. Tail line
Generally, the tail line has DC power supply and RJ45 network port. Ball machines with extra features can bring these functions out through the tail line.
