Clients are often faced with the option of choosing between n Standalone (embedded) DVR (Digital Video Recorder) or a PC Based DVR System. When deciding on which system is best suited for your project, it is important to note the following differences:
• Standalone DVR is older technology which is based on a Standalone unit with all components included namely CPU, DVR Card, Hard Drive(s),etc.
• The OS (Operating System) and DVR Software is on a chip.
• A PC Based DVR System is a normal PC which is equipped with a DVR Card and the necessary input/output ports and accessories.
Clients must ask the following questions when deciding between the 2 options:
• Why do I need a CCTV System
• What does the CCTV System need to do
• Conditions under which the system will be used

Variables such as recording and/or real time viewing capabilities and the the ability to change/upgrade are the most critical aspects to consider when making your decision .

Advantages of a PC Based DVR System

They are flexible. They are easily upgradeable and can be expanded to include as many hard drives as required, CD Burners, DVD Burners and Internet Capabilities.
PC Based Digital Video Recorder Security Systems are normally considered easier to operate.
A PC Based DVR System can easily be upgraded from a 4 channel DVR to a 32 channel DVR with little effort or cost.

Advantages of a Standalone DVR

Standalone Digital Video Recorders are normally equipped with Linux as operating system(embedded) which is excluded from the outside world.
The advantage of this is that it is less succeptable to virus attacks and subsequently less maintenance intensive.
Standalone DVR’s are more diverse in utilization in extreme conditions. PC’s are normally sensitive to temperatures and will subsequently affect your decision although this problem could be addressed by ensuring the correct housing of equipment. Standalone DVR’s are also not subjected to Microsoft Anti-Virus software and subsequent continueous updates.
Standalone DVR’s can unfortunately only expand to 16 channels.
An important aspect to keep in mind when making your decision is that more features and functionality requires more training and skills. 
It must also be noted that technology changes fast. A PC based DVR System is considered a more adaptable system and thus an advisable option.

Advantages of both DVR Systems:

PC-BASED DVR
• Utilization of existing IT infrastructure for remote monitoring and backup
• Maintenance by company’s IT technician
• Upgradeable Computer Hardware (HDD size, Processor
   Speed, Graphics etc)
• DVR channels can be upgraded
• Easy availability of spare parts
• Familiarity of Windows Software
• Stability of Win2K’s NTFS file system

• Similar to a VCR 
• Can be used for mobile applications
