It is well known the fact that, at this moment, on the video surveillance equipment's market, there are solutions that provide access to an IP camera using the web browser on a mobile phone. We will present you, herein, the advantages of the 3rdeye technology towards the mobile phone's web browser access.
The web browsers' type and version may vary from one producer to another and, even from one phone model to another of the same producer. This can lead to real functionality issues; the video surveillance won't work the same on the mobile phones with web browsers. Moreover, there is more than one video streaming technology that the IP cameras use, therefore, the chance of two mobile phones to be compatible would be even lower and using the web browser in order to access the IP video cameras almost impossible. With 3rdeye, these compatibility issues practically, don't exist, as we use the same dedicated client application that works on every Java MIDP 2.0 enabled cell phones.
For the IP video cameras, the video stream's parameters (e.g. the size of the image, the clarity and the compression rate) are set when configuring the system or initiating the connexion; they are maintained the same during the whole length of the connexion and for all the clients that connect to the respective video camera. The advanced algorithms used by 3rdeye's Video Streaming Server allow, for each mobile phone (considering the phone's display and the GPRS connexion's band width), the real time adaptation of the video stream's parameters: the size of the image, the frames per second rate, compression rate and the quality of the image. Another major advantage offered by 3rdeye technology is the possibility of simultaneous view of different areas in the video camera's visual field, by each client, with specific zoom level for each area. Moreover, the system's architecture allows using video cameras based on different technologies (CCTV, IP cameras, wireless cameras, web cams etc), the cameras being accessed unitary by the client application due to the fact that the Video Streaming Server provides the same video stream format, regardless of the video source's type.
One of the most important parameters presented in the technical specifications of the video surveillance systems is the frames per second rate (fps rate). Accessing the IP video cameras through the mobile phone's web browser won't allow you maximum performances, regarding the fps rate, when using a GPRS connection. The compression and video streaming advanced technology, both developed by Cratima, makes the fps rate exceed the 10 fps limit, taking into consideration the quality of the GPRS connection. Therewith, the adaptive compression algorithm optimizes the band width's usage, obtaining, in this way, a very low data transfer (approx. 100Kb per minute), considering the fact that the fps rate is very high and the quality of the image is very good.
