IP Video Surveillance
IP is the abbreviation of Internet Protocol, transmitting video image by utilizing open internet protocols and standards for the purpose of recording and monitoring.
An application of video surveillance on IP creates pack of digitized video data which are transferred on a network using wired or wireless IP. It allows control and video recording on all zone covered by this network, while enabling the possibility of including other types of systems such as plans of control of access.
Because of its progressive scan, the video surveillance on IP is a famous technology, worthy of recognition, not only for the classical actual remote applications of surveillance and control, which it can ameliorate or revitalize, but also for a huge number of new applications in many areas as for instance:
Education: security and remote control of schoolyards, halls, schoolrooms and security of buildings.
Transport: remote control of the rail railway stations and quays, public highways and airports.
Banks: traditional applications of security inside banks and their subsidiaries and wherever there are ATMs (Automated Teller Machine).
Administrative services: applications of surveillance of security, often inserted into the actual and future systems of access control.
Trade: security and remote monitor for a more efficient and easier management of stores and shops.
Industry: control of the manufacturing technique, logistical systems, systems of stock control and storage (with a variety of a particular interest and which will not be treated in this file, which is the recognition of form in production lines).
Network Camera
Not to be confused with Web Cam, a network camera is a camera which is directly connected to network (and not in a PC).
The network camera links optic functions of a camera and the capacity of a small computer equipped with an internal Web server. A network camera has a computer network connection of RJ45 for direct switch connection.
This camera broadcasts its pictures in every post which makes it request via a navigator on Internet network.
The IP camera has been designed to transmit visual pictures on the Web without the need of using a computer. The camera IP is therefore considered to be autonomous.
Camera Server
A camera server contains all server particularity of a network camera but does not have integrated camera.
It is necessary to add an analogical video camera to the server of classical surveillance camera. The combination of server camera and analogical video camera is identical to a network camera. A camera server includes therefore a computer network using RJ45 connection and one or several coaxial connectors to link analogical cameras of the network.
When to use a network camera or a server camera?
The network cameras are the new standard of the video surveillance or the animation of Websites. They considerably give you the possibility to alleviate the expenses of installation and wiring. The cameras server allows to recover the existing installations and to make them accessible to the network of subscribers.
A second application of the cameras server consists in linking to the network of cameras having special optic or mechanical characteristics (cameras infrared, miniature, mobile cameras, etc).
How to view the images in real time?
To visualize the live pictures in real time on a PC linked to a computer network, special software is customized for this purpose. This functioning mode allows you to make very simple video surveillance in real-time on the network. It is in this mode of real time visualization that the cameras give the best performances in number of pictures per seconds.
How to visualize and to remote control a mobile camera in real time?
The system gives you the possibility via the visualization software to operate by remote control mobile cameras if required, for instance: in big expanses, big areas, large scale production lines and commonly where they need to pilot a camera to the right and to the left and downward and especially to focally zoom to most important details.
How to record all the images of all the cameras?
The system offers you a recording server« plug and play » which is enough to connect up on computer network and to automatically record all IP cameras and analogical cameras (across the cameras server). All this recording is stocked in hard disk (size of which must be proportional to the number of existing cameras and to the number of days which is required to record: 1 week, 1 month…)
How to visualize the recording
The system also offers you as part of this resolution; numerical recording, a visualization recording software. (without stopping them).
It is an intelligent software accessible from any PC of computer network via a navigator web (Internet Explorer or other one) to Choose the day of the sequence to show, to Choose the hour of the sequence to show, to Choose the month of the sequence to be shown, Visualization of files recorded in normal mode, Visualization of files recorded in mode time laps (very quick)
The Advantages of Video Server
- Use of existing computer wiring, visualization on PC, no specific monitor (TV or other one).
- Broadcasting of pictures, in real-time or in postponed time.
- Permanent recording or customized.
- Automatic deletion of recorded pictures.
- Visualization of recording via a simple WEB navigator.
- Function "digital video cassette recorder" with fast-forward.
- Increased security, no video traffic on the subscribers’ network during recording.
- Control and administration of the system from any post of the subscriber.
- Management of the rights of visualization to user level.
- Choose a Camera to be shown.
The Latest Information on Security Camera Video Surveillance
Newer models emerge each year for video surveillance cameras. Each new model comes designed specifically with more functionality, in addition to a plethora of updated and features to purchasers worldwide. With buyers fueling the market, this year will not be an exception, the market is thirsty for the unveiling of newest options in video surveillance systems. This new breed of cameras with the technological advances of, including; multiplexers, wireless, and DVR's, is generating a storm through the industry.
I propose to give you a perspective on the many aspects of video surveillance, and the resulting impact these brand new systems will have on the worldwide market.
Wireless Video Surveillance
As with the launch of any new surveillance systems in the past, there was always a strategy before the launch of new surveillance products. Leading companies such as Toshiba, Pelco, Sony, and Panasonic launch competitive marketing campaigns to overtake the competition in the race to saturate the market with their product.Back in 2005, wireless technology was introduced, at a technology conference in Japan. Since its birth, wireless surveillance systems have become increasingly popular, and seem to be the first choice for security in many homes and condominiums. This is chiefly because of the ease and reliability of use and implementation.
The benefits of wireless security include the higher secrecy level due to the elimination of any wires and the ability of the system to function anywhere., Many models also come with the ability of full range of movement including tilt, pan and zoom. The top of the line systems feature MPEG-4 for better quality images and frame rates to choose from if the user wishes to link to his or her system by a computer.
Multiplexing
With video surveillance systems comes the use of "multiplexers." These devices permit many signals to share one resource. Multiplexers usually need a demultiplexer. This reduces the multiple streams of data back at a lower rate stream of data.
This basically translates into the fact that in relation to surveillance cameras, multiplexers enable a system to send back a live data stream, at the same time as recording other streams ready for video playback.
Digital Video Recorders
As with any good surveillance system one needs a DVR to allow the user to record the data streams coming from the camera itself. There are many systems out there on the market today, some come equipped with a multiplexer built in and high quality hard disk recording. What will it cost the purchaser? I In monetary terms these systems can cost much less then a typical VCR and multiplexer combo.
With the need for security increasing on an almost daily basis, you can probably see by now, the above are some of the reasons why the new brands of video surveillance cameras and equipment have garnered so much interest. With technology advancements moving forward rapidly on an almost daily bais, these systems will remain a source of security and peace of mind for people for many years in the future.
How to Compare Video Security Systems
Keeping an eye on the safety of your home and family while you are at work across the city or on vacation halfway around the world is of increasing importance to many Americans today. Find out how to compare video security systems and discover the right tools for your home monitoring needs. Keep your family and your home safe.
Video security systems use a certain type of camera to keep an eye on your home. Surveillance cameras, night vision security cameras, wireless cameras, and infrared cameras are the most popular options used alone or in combination for a total security package. Surveillance cameras may be fake props designed to simply act as a deterrent or they may be covert lenses hidden in ordinary home items and record video without being obvious. Night vision security cameras are designed for low-light areas and, while helpful for dark outdoor areas, they can also be used in any dim rooms or areas of the home or yard. These cameras usually record in black-and-white in order to best capture the events within the scope of the lens. Wireless cameras are extremely popular because they are easy to set up and can be moved without hassle. Wireless cameras are often small and discreet without the telltale wires snaking up the wall or along the ceiling. This can be useful for particular home decorating or secrecy needs. No matter what situation you are seeking to remedy, chances are you can be helped by concrete footage.
The extent of video security systems used in the home depends on the size of the home and the particular requirements and needs of the family members that want to do the monitoring. There are a wide variety of systems available from the continuous monitoring akin to CCTV video security systems found in casinos to smaller single-camera systems that are simply triggered by movement. You may want to work with a professional to determine your individual security needs and find the right system for you. Certain areas of your home may benefit from motion recording only, while other areas might warrant continuous monitoring with software that allows you to view activity online while you are away from home. Cameras that automatically sweep the room are also available and allow a greater scope of view with less equipment.
Some of the other technology that complements video security systems include the installation of digital recording devices that allow the video to be stored and viewed at a later time. If you are not monitoring the surveillance as it occurs, as with security officers in a large skyscraper, the images are lost and wasted. Most families that are the victims of theft want a video recording to help aid the police in capturing the people responsible. Video images may not bring back your goods, but it may help prevent the same person from doing the same thing to your neighbor.
Investing in video security systems is a wise idea for many home owners and families interested in protecting their belongings and providing peace of mind.
