-
Multi-camera control function
Select different camera only by mending dial switch setting, no any hardware or software needed. It supports SONY, HITACHI cameras and so on.
-
Proportional pan
Horizontal and tilt speed change automatically with the zoom changes. When zooming wide, the camera speeds down; then zooming narrow, the camera speeds up to catch better tracing effect.
-
Auto scan
Auto scan refers to the function of 3600 continuous scan the images at certain speed on the horizontal lever when keeping the pitching angle unchanged. The left and right limits can be set for continuous scan at certain speed on the horizontal lever.
-
Auto flip
When the camera tilts downward and goes just beyond the vertical poison, the dome rotates 180°. When the dome rotates, the camera starts moving upward as you continue to hold the joystick in the down position. Once you let go of the joystick after the dome rotates, joystick control returns to normal operation. The auto flip function is useful for following a person who passes directly beneath the camera.
-
Preset
Any position of dome camera PTZ can be conserved. We call it preset (pre-established position). The preset can be transferred and cleaned.
-
Preset tour
The dome camera will transfer pre- established preset 1-8 every 10 second. It will leap over to next preset position if position in not among 1-8.
-
Pattern
The PTZ orientation move track of the camera can be stored, we call it pattern. The pan& tilt’s UP, DOWN, LEFT, RIGHT and the lens’ FAR, NEAR can be stored. Also we can call the presetting. This function can be used to record and simulate the operator’s operation process.
-
Zero test
The camera will turn to horizontal and tilt zero by preset 34 when the inevitable desynchronizing appears or the operator wants to find zero position during working process. It can reset the orientation and is convenient for operator
-
Low pharosage (colors/ black& white swift) function
The camera automatically changes CCD pharosage according to surrounding light. Color image changes to black& white one in low pharosage; black& white image changes to color one in high pharosage.(related to camera)
-
Auto focus
The camera automatically adjusts lens focus to keep clear image if auto focus mode. Manually operate FAR or NEAR focus adjustment can also adjust focus. The dome camera will recover auto focus adjustment function if operate horizontal, vertical rotation or control lens zoom.
-
Auto iris function
The camera automatically adjusts iris to keep normal brightness in auto iris mode. Manually operate OPEN or CLIOSE iris adjustment button can also adjust iris. The dome camera will recover auto adjustment function if operate horizontal, vertical rotation or control lens zoom.
-
Backlight compensation
The object will become black as the shadow if strong light appears in background. Backlight compensation function can compensate the brightness automatically to dark objects in bright light background and adjust the brightness background to avoid the image full of brightness and get clear image. Too strong backlight can make the object illegibility.
-
WDR (Wide Dynamic Range)
If there is quite dark and quite bright in the image, WDR can make the darkest and brightest balance to keep clear image
-
Privacy Zone
Be sure protected zone be blocked when using the speed dome camera. The covered image moves with the rotation of pan/tilt and varies with zoom, to keep the privacy zone covered.
