Tv new "weapons" 3ccd camera pan and tilt b - Electrosurgical Cables Manufacturer
IV-related 1, camera matching 3CCD camera selection from the first CCD camera size (image acquisition CCD), horizontal resolution, SNR, Minimum illumination, SDI signal parameters into account, and then matching the lens can be considered Finally, from Other factors to consider specific camera manufacturer and model. Generally speaking, the smaller the size of CCD and the cheaper price, from the video conference point of view, 1 / 3 "has been fully meet the requirements, but due to the lens of this type of matching is not a lot, large meeting room may need matching one / two "or 2 / 3" camera. all involve television or broadcast system, the proposed use of CCD 1 / 2 "or 2 / 3" system, in order to ensure the video images can be compatible with the television system, and workplace conditions An optional SDI interface with cameras, to provide further transmission characteristics.
It is noteworthy that many users now on the market with a 1 / 4 "below the 3CCD camera pan and tilt system, which is not desirable, the price of such machines with 3CCD camera pan and tilt system, rather, at the same time Because the CCD layout is too small and can not obtain a higher sensitivity and the sensitivity is simply not suitable for broadcast, but generally such machines as one machine PTZ, camera, camera integrated in a device , lens focal length is short, do not Optional lenses can and can not adapt to the needs of important occasions, such machines generally close to the surveillance of technical indicators or household-level camera, does not meet the demanding occasions.
2, Lens optional Selection from supporting the camera lens, camera object distance was the size of the field of view, close-up format to be matching, the lens needs a few millimeters can be calculated out according to the actual situation:
Camera matching formula Lens matching formula
Where H is the height of the object being shot, l is the distance between the object being shot, image distance about equal to the lens focal length f, H 'The sensitive CCD camera for the corresponding region of H values, is the field of view.
In matching lens, the first choice you need to know how CCD cameras, such as 1 / 3 ", 1 / 2" or 2 / 3 ", so that the corresponding H 'value, then as long as the objects that need to be proactive height and distance can be calculated how much we should choose the focal length of the lens. calculated as follows:
F = (H ÷ H ') × l Note: the lens calculator provides a variety of calculation methods that can automatically carry out operations, such as the known focal length lens or field of view, we can calculate the height of the object to be proactive and width.
V. Conclusion Beijing World Trade Technology Development Co., Ltd. O-lin should request the relevant state ministries and commissions and market needs, developed a new generation of large-scale digital 3CCD video camera remote control system, to fill gaps in the system in the world. The system can be used for sports venues, meeting rooms, auditorium, studios, OB vans, school teaching, theater, shopping, weather information, traffic information, city landscape, dangerous situations such as live video, broadcasting and for the record, especially in better reflect the large stadiums this advantage.
With the scientific and technological development, 3CCD camera pan and tilt system will be in the stadium for more and better applications, users will be more and more choices, Beijing O Lin WTO will try our best efforts customers most in need of high-tech products to allow customers to install affordable, with good. I believe the joint efforts of the industry, the company can bring the best products, the most comprehensive system dedicated to the needs of our customers together to create their own national radio and television control products.

I want to use a camcorder as a webcam and PTZ?
I have no idea where to start. I have asked a couple people from the Sony website and they are useless. I don't think they know what I'm trying to ask or something because they are no help at all. All I want is to use a camcorder as a webcam, and at the same having a remote control in my hand being able to pan, tilt, and zoom it. I am looking to buy from sony. What do I need to do this? Is it the tripod that zooms, pans, and tilts? I am lost! Please help! =( thanks.
There is no single device that can control the pan, tilt and zoom if you are supplying the camera. Since the camera has the zoom... and the pan/tilt head will be made by some other company...
The cheap consumer web cams that do pan/tilt/zoom like those from TRENDnet and many others do what they do because the pan/tilt mechanism was built WITH the zoom function - all together.
There are more sophisticated security/surveillance cams that were also built with pan/tilt/zoom as port of their design.
If you insist on suplying the camcorder, a tripod or pan/tilt head mounted to the tripod can take care of part of the equation - but the zoom part in the camera gets tricky... you either need to magically integrate the camcorder's wireless IR remote with the pan/tilt function or the camcorder needs a LAN and THAT needs to magically integrate with the pan/tilt function. Since you did not tell us WHICH Sony camcorder you are using, for all we know, it can't even do the web-cam part anyway... but we have no way to know.
To the best of my knowledge, Sony does not have a consumer-grade PTZ camera or a pan-tilt tripod head... but they do have them in the professional products area... The Sony BRC200 and BRC700 are pretty good. For PTZ security cams, the Sony EVID70 and EVID100 are good, too.
For a cheap pan/tilt head, try the Bescor MP-101.
