Ellipsoidal head

There are 2 types of Ellipsoidal heads:

* Ellipsoidal head 2:1 acc. ASME VIII Div. 1 and 2
* Ellipsoidal head 1,9:1 acc. NF E 81-103

The dimension values 2:1 respectively 1,9:1 are the ratio between the small and the large axis of the ellipses. Both head shapes correspond nearly to the geometry of the Semi-ellipsoidal head acc. DIN 28013. The dimensions can be approximately calculated as follows:

I'm using camera application. I can webcast Ip video to view my site from anyplace.

With my new webcam software, I can run a streaming webcast of my apartment visible from the Internet. This opens up a number of possibilities, the surface of which has not even been scratched in today's world. I can use this webcast for surveillance purposes, allowing me to watch what's going on in my site at any time from a remote watching pc.
As long as I have the webcamera running and a remote station with Online access, I can watch the site. With the software and the webcam, I can change the settings to capture picture, sense movement (if I don't want to keep the webcam running at all times), or use a combination of a live feed and recorded video to realize a protection system that takes full benefit of new technology.
With a capture card, I can simply move relevant video and screenshots to use on any pc.
With sensitive data on my pc and precious stuff in my site, it only makes sense to have a security setup that I can monitor whenever I feel that my privacy is being compromised. If I owned a small company or lived with roommates, I couldn't imagine living without it.

Broadcasting online video and sound from capture card through web camera computer application

Security application

If you find yourself with a need to record security video with a webcamera over an area, camera computer software may be the right choice for you. Using this application, it is possible to set up a camera to detect motion and begin recording once it does.
Depending on your needs, the sights and sounds that are picked up by the camera may be stored on a hard drive, or if the captured video needs to be accessible off-site, can be webcast using the server's broadcasting function to a webpage.
Depending on the quality of the webcam and the viewer's video card, the picture that is recorded may be as clear as a high-definition tv signal. Using a install like this, it is possible to provide a measure of protection for an area while the economics of the situation do not justify hiring a security firm or setting up a professional monitoring system.
This do-it-yourself approach can save money while not compromising on protection.

New professional protection software works with any web camera, IP cameras, and major capture cards.

Surveillance software has become so complicated that the typical businessman who has been busy minding his office instead of pouring over electronics and ip technology articles can be easily overwhelmed when it comes time to setup or renew his security system.
Luckily, there is modern professional security application that simplifies much of the decision making. You don't necessarily have to get rid of a working analog CCTV system in order to update to a broadcasting video that can be watched from any ip connected computer or 3G phone. Video capture cards can digitally convert the snapshots for broadcast. Until yesterday, there had been no real attempts to standardize the new Internet cameras; every make and manufacturer functioned a little differently. And when you connect cameras into the join, using one application to control them all was unwieldy.
Professional security software is now accessible that will work for any webcamera or IP webcam and for most capture cards as well. You can monitor anything your movement sensors are picking up at your home or company while you can be half a globe away. The software itself may not be easy, but it can make life simpler for you.
