"DSP+Sensor" functional pairs in Proto-X IP video cameras
Proto-X IP video cameras consist of only state-of-the-art DSPs and sensors by the best worldwide manufacturers. The sensor is necessary for an optical image modification into an electric signal, and the processor (DSP) performs a primary conversion of the video signal: brightness correction, chromaticity, image contrast, as well as performs more difficult operations. The image quality depends on functions and capabilities of these parts.
To compare advantages of different functional pairs "DSP+Sensor" used in Proto-X IP video cameras, there is a summary table shown below:
|
SONY+HiSilicon
|
Aptina+TI
|
Aptina+HiSilicon
|
|
Sony+HiSilicon pair is distinguished by low heating, which protects radio elements from an overheating problem. Due to that fact it's possible to use the sensor and DSP on the same board. In this case there can be released a free space for locating additional modules, for example, PoE, audio input, SD-card slot. Proto IP-H2W20F36IR.
Aptina+TI pair is the most effective one, which forms an image with the resolution of 2-5Мр! The given pair is used for making 3Mp images in such Proto-X IP video camera models as Proto IP-T1W30V212IR and Proto IP-T1W30F36IR.
Aptina+HiSilicon pair is the most common one because of a low cost of it's components. It's characterized by excellent color reproduction and high sensitivity, and also makes an image of 1-2Mp. Proto IP-HW20F36IR.
 | Progressive DSPs, mounted in Proto-X video cameras, allow to process a video stream from a sensor with the resolution of 1920×1080 and max speed of 30 fps. |
 | A built-in algorythm of a video data digital processing enables to widen a dynamic range of a video camera. |
 | A digital algorythm of an optical distortion processing allows to obtain a sharply defined image apart from a focal distance. |
 | There is an ability to show an image from a video camera in a natural perception view apart from a mounting location. |
 | A video camera contains a power supply unit with PoE Ethernet cable, supporting 802.3af standard with the power supply of 15V on the device. |
 | A built-in audio signal processing module enables to lay an audio signal on a video stream from any external microphone or other audio source. |
 | A module supporting SD-card solid-state drives of 32Gb allows a video camera work in a fully-autonomous mode. |
It's always specified on our web-site, which type of functional pairs is used in one or another model. A more detailed technical information is located in "Specification" tab on every individual product page. If you have any questions, please, ask our engineers.
