TD-9622︱20X 1080P NETWORK IR HD HIGH SPEED DOME CAMERA

TD-9622
20X 1080P NETWORK PTZ CAMERA

Camera design
Elegant appearance, precise core
TVT TD-9622 20x 1080P network IR high speed dome adopts an aluminum housing to protect the camera body and the digonal & concave-convex surface design brings a great convenience to installation. The camera has 1/3 inch CMOS sensor and supports 20x optical zoom.
Definition test
Image performance stable and fluent
【Definition test】
With the setting of 1080P@30fps,4Mbps,
adjust the lens to the lowest zoom times and focus on the definition test card, the horizontal definition is about 1050TVL,and vertical definition is about 1000TVL,even the edge definition is about 900TVL.The definition performance is good
PTZ control
Excellent,accurate control
This PTZ camera adopts a user-friendly WEB GUI menu,supports a selected
rectangular area enlarge. The Pan range: 360°continous rotation; Tilt range:90°auto rotation. Supports 255 preset position with a speed at up to 240°/s horizontally and vertically. The test engineer set 4 different point of view,different optical Zoom preset position and input 1 cruise group,during a period’s test,cruise image is almost the same as the preset.So it proves the camera’s capability of an excellent,accurate control.
Stream test
Stable and perfect surveillance
【Stream test】
With a setting of 1080 p @ 30 FPS, 4 Mbps ( h.264 compression), and then start the steam test software, the average stream is about 4.5 Mbps -- very smooth and steady
Low illumination test
Excellent image quality
【WDR off/on】
Following is the light handling capability test, put the camera in the condition which has a big illumination difference in front and back ground( Illumination for front scene>30000lux,for background<100lux) When switch off WDR,the light is dark around the image and distributed unevenly. Switch on the WDR manually,adjust to level 1,the effect of WDR can be seen;adjust to level 2, the WDR effect is dramatically enhanced,
the light on the people face shows a strong difference to previously.
【Low illumination test】
Then put the camera into the darkness box, switch on the illuminometer and adjust the zoom times,lower the illumination,when the illuminometer goes to 8.4Lux(F1.6),the image switches to night mode;then adjust to color mode.
According to the test result,when the illuminometer displays “0.00”lux(F1.6),the image noise is large (this can be reduced via adjusting the 3DNR level),but the image is still clear enough to be recognized . So this camera has an excellent performance in low illumination.
Smart IR compensation test
Surveillance anytime,anywhere
【Smart IR compensation】
Final test is smart IR compensation. When switch off all the lights,IR turns on automatically, image is good.According to the test result,when test engineer walks in from 20m away with a pillow, watch the compensation area change,when test people is 1.3m away, the focal point was focused on the center of pillow. So the PTZ camera has an incredible performance at
smart light compensation function.
