Security recorders are divided to 3 main categories. Because there is quite a confusion when referring to "DVR" we will explain in a nutshell the differences.
Standalone DVRs are simply a dedicated unit with embedded operation system which was manufactured for the sole purpose of accepting analog cameras input and storing them on hard drive. Standalone DVRs are usually pretty limited with features and are not upgradeable. The Graphical User Interface reminds an old VCR settings menu and requires the use of a remote control to manage the system. Standalone DVRs are the most cost effective option compared to the other alternatives.
PC Based DVR is a computer fitted with a Digital Video Recording card installed inside the computer case. Using a computer provides better processing environment for the DVR card, as computers have stronger processors than standalone DVRs. Most PC Based DVRs will accept Analog cameras input and recent improvements allow for a hybrid system where both Analog and Digital (IP) Cameras can be installed on the same computer.
Naturally, PC based DVR have a user friendly GUI (graphic user interface), and are managed using keyboard and mouse or over the network. This makes managing the system and backing up recorded video an easy task for the operator. PC Based DVRs offer advanced features such as several video compressions to choose from, email alerts and integration with other system.
PC Based DVRs are upgradeable and sometimes are capable of adding an additional DVR card if the system needs to expend. That provides a cost effective, feature rich, expendable security system.
Network Video Recorders are computers with software installed to manage IP and MegaPixel Network Cameras. Since IP cameras work on network, the quantity of cameras is limited by software licensing and unlike analog recorders there is no hardware limits on the recorder. if need arise to add more cameras simply purchase additional licenses and connect the new cameras.
Network video recorders are usually fitted with a large amount of storage capacity and additional storage is possible by adding additional drives or using Network Storage devices.
NVRs offer the most advanced video features and analytics however because IP cameras pricing are still relatively high the total cost of a system usually is more expensive than analog system.
Smart Security Camera installed a PC Based system in my Sporting Goods Store. It was a much needed system that I put off installing for fear that the cost would be out of my price range. Smart Security Camera’s representative helped me find a system that was within my budget, without trying to up sell me. They were very professional and patiently answered all of my questions.
The new system gives me the freedom to leave the store without having to worry about product loss. I highly recommend Smart Security Camera to anyone looking for a security system.-Aaron Norman, Sport Goods Imports Inc.
I'm amazed by smart security camera who computerized my whole entire restaurant operations, it stands to gain some very important benefits. Orders and money transaction are tracked and fully logged, check totals are always correct, all integrated with this wonderful 24 cameras CCTV system.
I'm able to remotely connect to my restaurant system to check on my 4 point of sales, my line of cooks, check on a period of 75 days of 24/7 recorded videos etc..
People work together better than before and waste is reduced by 50%, as well as theft is completely eliminated. At the decent price I paid for computerization of my systems I received a peace of mind and an increase of 15% benefits, I'd greatly suggest smart security camera for computerized systems.-Scott Meredith, Silver Fish Lounge, Ft.
