Thanks for your cooperation! 1. True or False (34*1) 1. H.265/High Efficiency Video Coding (HEVC) is the successor codec to H.264. The primary goal of the new codec is around 50 percent better compression efficiency than H.264. ( True ) 2. By adopting Predictive Encoding, Noise Suppression and Long term Bitrate Control, Hikvision H.265+ can save the bandwidth greatly in certain scenarios. ( True ) 3. When the sensor size is fixed, longer focal length will make large FOV. When the focal length is fixed, larger sensor size will make large FOV. ( False ) 4. Flow analysis camera can count how many people in a certain region, and their waiting time. (True) 5. Compared to 1080P, 1080P lite can get almost the same quality with lower bitrate. ( True ) 6. For Hikvision people counting application, users can get the people flow statistics from web client, iVMS 4200/HikCentral and NVR. ( True ) *** 7. For Hikvision people counting application, users can save the people flow statistics even there is no SD card in the camera. ( False )*** 8. People counting camera can focus on a target and track it until it disappears in the image, thus Hangzhou Hikvision Digital Technology Co., Ltd. All Rights Reserved. effectively filtering the repeated count of the loitering target.. ( False ) (prevent) *** 9. Hikvision NVR can export its IP channel as an Excel that is only readable but not editable, and this excel can be imported to another NVR of the same model. ( True ) 10. For the application of VCA functions such as line crossing, object removal detection, etc., NVR has integrated in its firmware, regardless of IPC models ( False ) (FaceSearch, Plate, Heat) 11. ColorVu camera can only provide black &white image when there is no illuminance (0lux). ( False ) 12. If an IPC is plugged into the POE port of an NVR, and NVR is in the same LAN with the operator PC. Then the operator can enable the NVR virtual host function to login the web page of the IPC. ( True ) 13. To remote playback the NVR record file by transcoded stream, it requires not only the NVR, but also the IP camera should support transcoded stream. ( True ) 14. When an IP camera has SD card on board, it will always store pre--record videos in the SD card, even ANR function is not triggered. ( True ) (Triggered or Enable) 15. In the ANR application scenario, ANR synchronized recording can be found in the record file list. ( True ) 16. For Hik--connect, Sharing function is not supported under visitor mode ( False ) 17. Hik--Connect visitor account can’t be upgraded to official account. (False) 18. To build a RAID 5, at least 3 hard drives are required. (True) Hangzhou Hikvision Digital Technology Co., Ltd. All Rights Reserved. 19. If you forget the device password, you can extact key file from SADP tool and send to Hikvision technician for resetting ( True ) 20. Image/Video adjustment are supported on playback interface of NVR 4.0( True ) *** 21. Sensitivity should be modestly adjusted lower if you want vehicles instead of the pedestrian to trigger the alarm. ( False ) 22. Acusense devices filter non--human targets by measuring their temperature. ( False ) 23. When PTZ camera is zooming in or zooming out, the IR always keeps the same angle and power. ( True ) 24. PTZ smart tracking 2.0 support human & vehicle classification ( True ) 25. When WDR function is enabled, max frame rate can be set as 60 fps ( True ) 26. If we set smart tracking duration as ‘0s’, the PTZ camera will always track the moving object until it is out of the camera’s coverage. ( True ) 27. ROI (Region of Interest) function assigns more encoding resource to the region of interest, thus to increase the quality of the ROI whereas the background information is less focused. ( False ) 28. A higher frame rate camera which can reach up to 50/60 fps is advantageous when there are some fast movements in the video stream. ( True ) 29. The OSD information such as date, time, channel information and even some text can be overlaid on the live video of Hikvision camera. ( True ) 30. Hikvision cameras can be activated via web browser, SADP and client software. ( True ) 31. Hikvision NVR can support eSATA function, which can be used for recording or capture storage. (True )
