Digital Video Recorder

The DVR replaced the previous model of multiplexer added with VCR. The previous model supported three hour long tapes with twenty five images per second while that playback had to be done through the multiplexer. With time and faster processors came along DVR which can record up to 480 IPS, the storage of thirty days can be turned to sixty or ninety as one desires. And this system brings the new feature of recording only when there is any motion in the place, called Video Motion Detector (VMD) and that saves up a lot of space creating a lesser load on the memory bank. With the pros of DVR security system comes the cons.Hard drives which might easily fail can compromise a bunch of important surveillance footage. The maximum resolutions offered by them remained around 640x480, which is VGA quality. The medium quality videos leave doubts about which can quite often be a dead end in an important point of the investigation in Houston, TX. DVR system is hard to update owing to the video cards, software and the operating system.

Network Video Recorder

The limitation in a DVR is that it compresses the live video feeds analogously while storing them on the memory disk. The NVR holds back digital images which are not yet compressed from the IP camera. The NVR is a better recorder than the DVR which at times can cause lapses. The NVR apart from being such a great recorder supports all video resolutions up to 1080p giving the users great view of what is happening. Being less expensive than the DVR systems due to the absence of cables, at the time the NVR system is preferred. The system provides great changeable memory disks. The systems come with a very user-friendly format and user interface and the touch screen feature adds to the user friendliness. Videos can be copied from the system to a personal hardware or PC for further investigation.

Which one to buy?

The NVR records better with a more stable connection which is through a network switch or router in other cases. The transmission process is one of the more striking features in the difference between the two. The NVR system provides the customers with better quality, better transmission, high definition videos and is less expensive than its only competitor in the Houston market. NVR is a more common choice among customers.

"Steve I just wanted to thank you and your partner Ray Kindsfather for the fine work you men did installing the security cameras around my home. The quality of the pictures is excellent, the clarity in day or infrared mode is exactly what I was looking for. What good is a camera if you can't identify the person and these cameras will greatly assist the police in identifying a perpetrator. The computer side of the job is easy and fast with very little adjustment time for me in finding what I want to see. Software and hardware get A+++++ no doubt about. The Ring is equally easy to use and the quality of the camera is equally strong. The installation was clean and fast. You maintain a clean site, it’s like you were never here. You answered all my questions with pin point accuracy. Integrity suits you well. Your answers were honest and to the point. Refreshing in today’s world. All and all you and Ray make a strong team at DWS Technology LLC. I have no problem recommending you to friend or family, home or business. God bless you both with your business. I will call you for future installations. "

"Ray, in reviewing several different security cameras there were many good products, but none met my criteria of clarity and no long-term contract. Raymond, you showed me one product that caught my attention with the clarity and distance viewing that I could not get with other systems. The zoom after a few feet became distorted with the other systems but with the Alibi NVR package you demoed, we could zoom in and out with clarity which made this product stand out from all the rest. The NVR system is so simple, in fact, anyone can configure the system to suit their needs. You can monitor your home from your smartphone or tablet and having security cameras makes it a great deterrent for criminal activity. DWS Technology delivered as promised! Your installation crew worked clean and treated my home as if it was their own. Great attention to detail! I will recommend DWS Technology to anyone! Great job guys!"
