What is real time video ?

Optic / Lens Determine the coverage Lens type – Auto Iris / Manual Iris / Fixed Iris

What do you need to see? Classification  Target can be distinguished between human and animal. (i.e. an upright human or animal walking on four legs) Detection  A target is determined to be present in the camera’s field of view. (i.e. something in the field of view is present and/or moving) Recognition  Human target is determined to be a threat by the type of clothing and/or equipment being carried. (i.e. friend or foe) Identification  Human target can be identified as a specific individual. (i.e. a specific person)

Camera Technology Day / Night Switching Wide Dynamic Range Light Sensitivity – Lux Resolution – Megapixel / HD / 4 CIF

 True B/W Mode with IR filter removed  Sensitivity increase in mono mode Dinion XF Day/Night Color Mode Dinion XF Day/Night Mono Mode Day/Night Switching

Wide Dynamic Range Technology Enhance the image when the camera is capture the image with the uneven light and strong back light.

Illumination - Lux  Camera output signal standard is 1 V pp (full video)  IRE (Institute of Radio Engineers) value The full signal is 140 IRE (1 Vpp) The video part is 100 IRE The synchronization part is 40 IRE

Video Streaming Video Compression Technique Advantage Introduction to the IP Imaging Technology

What is IP CCTV / IPVS ?

Utilized the advantages of IP network, computer hardware and software. Live and Recorded Video are fully encode into digital format ! IP Camera are addressable, can be access anywhere UTP Cable

Video Streaming

Video streaming using unicast Unicast – the sender will sent a video to the receiver that request the video, Max 5 receiver. Video stream 1 Video stream 2 Video stream 3

Video streaming using multicast Multicast – the video will distribute by switcher to a set of receiver, Max 50 receivers with RCP+ Protocol. Broadcast – the video will distribute by switcher to a set of receiver, Unlimited receivers.

Video Compression Image over compress

Joint Photographic Experts Group – JPEG Motion-JPEG compression technique -Compress each video frame separately into JPEG image -Priority is given to image resolution – cause longer image delay over low bandwidth. -Every images have a consistent file size Key Advantages -Technology is simpler, can lower the price for the hardware.

MPEG Compression Technique

Question 1.How far the camera can see ? 2.How clear is your camera image ? 3.How long can the video record ? 4.What compression technique Uniview IPC use ? 5.What is the different between HD and Megapixel IPC ? 6.What is the advantage of the IP CCTV against Analogue CCTV? 7.What is the purpose for the Infra – red illuminator ? 8.What is the advantage of the Wide Dynamic Range ( WDR) ? 9.What type of lens will use for detection purposed ? 10. How Many frame per second for real time video ?
