DVR is an integrated system which accommodates different combination of multiplexers, quads, video recorders and alarm controllers. This system represents a great step forwards beyond any of conventional analogue surveillance systems. The system not only performs monitoring, motion detection, alarm control and different electric/electronic devices control at the same time, but also stores images from camera into hard disk for playback later.
Through networking it can be easily accessible from anywhere and at any time. Further, the system employs an easy-to-use interface which maximizes the efficiency of the surveillance.
We are proud in introduction of these user-friendly systems to you. The system is best equipped with advanced technologies.
Recording device which is a part of a CCTV camera system. The DVR replaces time lapse recorders as well as Multiplexers. They are composed of a computer hard drive and video inputs. Typical configurations include 4 channels, 8 channels, and 16 channels.
There are many advantages to using a digital video recorder such as motion activated recording.
Recording times are based on the amount of disk space available and the frame rate specified.

PC Based DVR
DVR Cards enable the user to convert their computer into a Digital Video Recorder. The DVR Card(s) is typically installed in an available PCI slot of a computer. DVR cards are bundled with video surveillance software which allows the user to record and display multiple cameras simultaneously from the camera site or a remote location.
A DVR card is the most recommended for long term surveillance. This will allow for motion activated recording, timer recording, remote access, and many other features.
For laptops a USB capture card or USB DVR will connect via a USB port and provide very basic surveillance. you will then use the software that came with the USB hardware to record the video.
What are the minimum requirements for a PC to be used with your DVR cards?

Why H.264 compression technology?
The new industry standard H.264 compression technology is causing a revolution in the Video world, enabling higher quality, lower bit rates, lower system cost and new applications. New H.264 system provides the same low-latency video that has been delivered by traditional MPEG-4 based systems but with a reduction of up to 50% in bandwidth and storage requirement – or to put it another way, H.264 system can deliver significantly higher video quality for the same bandwidth – to save your internet resource (or higher transmission speed) and hard disk place also. Motion Detection.
Keep in mind however, that using motion detection can GREATLY reduce the hard drive use. The likelihood of your camera actually recording all day will be very slim. It may only record for a few hours per day on motion detection, making the figure more like less than 1Gb per day.
PC Based DVR
PC based DVR with the H.264 Compression Standard is available in 32, 48 and 64 Channels (By default al inputs are with Video & Audio).PC based professional digital security product adopts most advanced H.264 video compression algorithm and OggVorbis audio compression technology.
Newly designed PC based DVRs are more compact, steady and incorporated with 1GB RAM, 500GB HDD, DVD WR, Keyboard, Mouse and Windows XP "Professional operating system".
Compare the sizes and components. Coming with all the components compressed into one box, stand-alone DVRs are compact while PC-based DVRs are created around a computer and come with attachments like the separate CPU, keyboard, a USB mouse and monitor. A stand-alone DVR occupies less shelf space while performing similar functions.
Understand the utility of both DVRs. Get the stand-alone DVRs for fundamental requirements. They offer recording, viewing and programming ease, along with Internet access while the PC-based DVRs accommodate advanced features such as improved screens, improved motion detection facilities and Internet viability.
Compare the user friendliness of both. The stand-alone DVRs can be handled by any layman due to its clear-cut program interface and control buttons. It requires no special computer expertise. However, a PC-based DVR requires specialized computer knowledge.
Compare the storage space. Although the stand-alone DVR has ample recording and storing space, the PC-based DVR features as much as 7 times more storage because of a larger CPUs and memory.
Check out sophisticated features. The PC-based DVR has superior characteristics such as better reception of playback programs, colored bars for easy search, four times better speed, CD-ROM burner, DVD burner and easily attachable hard drives.
Acquaint yourself with the surveillance functions of both the equipments. The stand-alone DVRs come with up to 16 video inputs and are suitable for small space surveillance. On the other hand, the PC-based ones can accommodate as high as 32 and hence are ideal for malls, movie theatres, departmental stores, hospitals and industry units.
Compare the prices. The PC-based DVRs are more expensive than the stand-alone ones.
