CCTV Systems – Offering a Comprehensive Solution for All Your Office and Residential Security Needs
CCTV Systems is one of the most incredible security equipment that is now being used extensively at homes, restaurants, retail stores, supermarkets and offices for security purposes. These security systems offer complete peace of mind to the property owners enabling them to manage the security of the application area. Under this kind of security set up, the CCTV Cameras are installed in the application areas that need to be monitored and are directly connected to dedicated TV screens. Unlike a normal television set up, a security camera closed circuit television is dedicated to the purpose of monitoring the application areas and it does not convey any airwaves.
The common feature of business and home security CCTV systems is to help the manager monitor the activities of the area. Due to this reason, these systems are mainly used for highly crowded areas and those places that require higher security measures. They are often installed at places where security concerns are very high like airports, railway stations, banks, ATMs, jewelry shops, military installations, casinos, etc. Besides being installed in high security zones, they are also installed in areas where people are comfortable with the working environment like in offices, laboratories, schools, colleges, and so on. In such places, the CCTV Cameras are installed for recording the regular day-to-day activities, which is being monitored regularly by the management. Following are two most important benefits of using office or home security CCTV systems.
Prevention of crime:
Places that are well guarded by the CCTV Cameras fall in the category of highly secured areas, therefore the burglars and thieves usually try to keep away from intruding into such places for the fear of being watched. Further the CCTV set ups also enable the users to record all the activities at the application areas, which help the owners to indentify the thieves / burglars or deceiving employees during crime investigations.
Protection of The Habitants / Employees:
The most advanced CCTV Systems are the best security devices that offer complete safety to the users. Whether it has been installed at your office or home, you can stay relaxed knowing the fact that all the activities are being watched over and recorded. It has great usage in the offices / shops dealing with high value products like jewelry or important database or confidential information. Even the employees would feel safe working under the supervision of this security system as they would be sure that any loss made to the company would be easily detected by the help of CCTV recordings and only the culprits would be punished.

need to know how to install a cctv security system using a time lapse VCR?
I have a Sony time lapse VCR, three JVC CCTV cameras that I want to install on my house. I have an idea what kind of cable I need for connecting the cameras, but I don't know if I will be needing an additional device to connect the cameras to. I have heard of a four channel quad processor, but I,m not sure. Please anybody help me clear the smoke.
That all depends on how you want to view the images. With a VCR as with any single channel recorder there are three ways you can go.
1. Sequential switcher - sequences camera's. You can miss things with this method
2. Quad splitter - splits 4 images onto one screen. When you play back you will only see the split screen and have no control over it. You will see everything but at 1/4 the size.
3. Quad multiplexer - sequentially sends images to the recorder. Also has the ability to take those sequential images from the recorder and "play back" in order. You can view played back images in split screen what ever you like.
example: numbers indicate camera number
record
1, 2, 3, 4, 1, 2, 3, 4, 1, 2 , 3, 4
Playback through Multiplexer
1, 1, 1
Obviously depending on the multiplexer you purchase, there will be spaces between the images (Not real time). Truth be known, with what you will end up spending if you go this route, you may just want to consider a digital video recorder (DVR) All images are recorded onto a harddrive and you can view them in a similar manner as the multiplexer.
There are also multi channel PC cards available, but I would definately not recommend this option. Computers crash and the quality is not as good as a dedicated linux box.
There is abit more info on video surveillance on my website. It may help you in answering any other questions you may run into. http://www.keepsafesystems.ca

Home and Business Security CCTV Technology Evolving From DVR to IPTV
Like most businesses, the video security camera industry tends to centralize and consolidate its systems to reduce costs and take advantage of new upgraded technology. This article discusses the advantages of an unexpected jump that could cause the premature obsolescence of Digital Video Recorders in the business and home security industry. IPTV, or Internet Protocol Television, enables all business systems like access control, fire alarm, phone, and computers to operate under one network. Video transmission over a network utilizes what is known as a virtual matrix as opposed to CCTV matrix switches. To visualize the difference, think of the difference between the portable CD players people used to carry to play one album at a time and the iPods now in fashion that can store hundreds of thousands of songs.
In its first ten years of existence the DVR has created a seriously high quality method of storing video images without any of the degradation of the former standard, the analog VCR tape. DVR provides efficient fast search capabilities and easy reviewing of the video, however the digital cameras use a server with analog video inputs and they are hooked up by coaxial cable just like analog cameras. There are a limited number of inputs and outputs for connecting with other systems and devices so once the inputs are full, if you want to connect to a control center you have to add another unit. Another drawback is that most DVR software uses non-standard digitization, compression, and closed circuit codes. This makes high-level integration with communications centers difficult. Although DVR security cameras have integrated hi-tech features like motion video, pan, tilt, and zoom, the limits on their flexibility become obvious when compared to IPTV.
It seems surprising that a better format would appear so suddenly but IP solutions offer significant advantages that would lower overhead by reducing redundancy and peripherals, plus provide for a much easier management of the systems. This is especially true for multiple locations and companies providing or using centralized recording and monitoring. By using convergence technology only one infrastructure needs to be maintained that can control all functions: intrusion detection alarms, temperature control, IP video, etc. which reduces costs and enables easier merging with new technology and software upgrades.
Better compression methods have overcome the initial problems with the heavy bandwidth for transmitting used with IPTV. There are two main formats used: Motion JPEG and MPEG4. The lower bandwidth per video stream of the MPEG4 gives it an advantage over the browser-based MJPEG but it needs a codex or applet for browser Web viewing. In a control center, the virtual matrix allows switching any video stream to any decoder due to decoders connected to all the monitors.
With such technology it seems inevitable that companies will need to consider it in order to keep up with the software of the future. As things stand there are high-security capabilities to videotape at a different frame-per-second speed and to playback or monitor at any other speed. This would mean that video evidence of any crimes, fires, or emergencies, if recorded at low frames-per-second would provide more critical detail for investigators to view. There have been numerous crimes solved by police being able to see high-resolution images from nearby business security cameras.
