Step 1
Understand platform-based DVRs. They are predominantly software-driven systems that depend on a platform, like computers.
-
Step 2
Understand stand-alone DVRs. They are independent DVRs that run on their hardware and don't need any external software. It is just a cabinet that combines all the devices and components required on a single board.
-
Step 3
Compare the flexibility of both the systems. A platform-based DVR can be upgraded using different software or hardware as the requirement arises. While this makes it flexible to use, it also makes the DVR vulnerable to hardware-software conflicts and related problems. On the other hand, a stand-alone DVR has embedded software in its IC chip, which cannot be modified or tampered with in any way. It means that it is a rigid system but it also eliminates any chance of hardware-software conflict and makes for a highly reliable DVR.

Step 4
Understand the difference in features. The most important feature of a platform-based DVR is that it's customizable. It can be attached to hard disks, CD/DVD burners and support Internet and telephone access. This is impossible with stand-alone DVRs.
-
Step 5
Understand the difference in utility between the two. With its flexibility and sophistication, a platform-based DVR is ideal for surveillance activities and for large organizations where the system will be handled by experts. A stand-alone DVR is perfect for users who want it independent of their PC or want to use it with their VCR. A platform-based DVR comes with a bigger memory depending upon the PC and can be connected to the Internet, making it better than a stand-alone DVR for commercial uses.
