3. What is “CCTV” Traditional surveillance system can be applied to observation from a distance by means of analogue video camera, the video camera also called CCTV (Closed-circuit television). An analogue video signal output from CCTV to recorder by coaxial cable. Before digital video and IP network technical become popular and standardization, traditional analogue video camera system already have 67 years history (The first CCTV system was installed by Siemens AG at Test Stand VII in Peenemünde, Germany in 1942).Peenemünde Most of market analysis report indicate that : compare with IP base video surveillance, CCTV still have large market share in worldwide Note: referecen data from Wiki o Video Encoder Introduction

4. What is “Video Encoder” An IP video encoder converts analog video(CCTV) signals into IP video streams. The IP video encoder can stream digitized video over IP networks in the same way that an IP Camera can. Because an IP Video encoder uses IP protocols, it can stream video over any network that IP can use, including via a modem for access over a phone or ISDN connection. With the use of a video encoder attached to an analog camera, the video from an existing surveillance system can be converted and networked into a new IP surveillance system.

5. Why “Video Encoder” In the video security industry a video encoder is a device to which one or more video sources can be attached. Video encoders are used to give existing analog systems network connectivity. Video encoders are essentially transmission/ telemetry / monitoring devices. Viewing is done using a web browser or in some cases supplied software. These products also allow the upload of images to the internet or direct viewing from the internet. In order to upload to the internet an account with an ISP (internet service provider) may be required. Note: referecen data from Wiki o Video Encoder Introduction

11. 11 H.264 H.264 is a best standard for video compression. It is also known as MPEG- 4 Part 10, or MPEG-4 AVC (for Advanced Video Coding). H.264/AVC is capable of providing good video quality at substantially lower bit rates than previous standards without increasing the complexity of design. In the IP surveillance application, H.264 will be a better compression method where there are demands for higher frame rate and higher resolution videos. H.264 can reduce the size of video stream around 80% compared with the Motion JPEG and as much as 50% than MPEG-4. Thus less network bandwidth and storage space are required. o Technology Brief

12. 12 H.264 Quality The improved compression performance of H.264 comes at the price of greater computational cost. H.264 is more sophisticated than earlier compression methods and this means that it can take significantly more processing power to compress and decompress H.264 video. A video frame compressed at the same bit rate compared as below figures: o Technology Brief * Picture source: Vcodex White Paper: An overview of H.264

13. 13 HTTPS for network security Hypertext Transfer Protocol over Secure Socket Layer or HTTPS is a URI scheme used to indicate a secure HTTP connection. It is syntactically identical to the http:// scheme normally used for accessing resources using HTTP. Using an https: URL indicates that HTTP is to be used, but with a different default TCP port (443) and an additional encryption/authentication layer between the HTTP and TCP. o Technology Brief

14. 14 HTTPS (cont.) The HTTPS cannot be enabled if there is no certification on the device. There are three possible ways make you can enable the HTTPS, create certificate request and upload the certificate file which is signed by third party already, create self-signed certificate automatically and Create self-signed certificate manually. o Technology Brief

15. 15 Privacy Mask for personal secret Privacy Mask feature allows you to block out certain sensitive zones for privacy. You can set up to five privacy mask windows in the same screen. Privacy masks will appear on all video streams and recording videos and will overlap with motion detection windows. As seen in the figure below, the masked area does not detect any motion. o Technology Brief
