What is the difference between a PC-based DVR and an Embedded DVR?

PC-Based DVR

  • Expandable (Can add additional cameras and/or storage).
  • Easy to maintain. If a component fails, an end user can replace it.
  • Can integrate with POS/cash registers.
  • Better PTZ integration.
  • Can work with IP cameras, as well as Analog cameras.
  • Ability to have more than one  user accounts.
  • Easier to interact by using the on-screen menus and a mouse, giving it more features and options.
  • However, when running a PC-based system you are vulnerable to hackers, crashes, viruses, attempts and system freezes.


Embedded DVR

  • Cheaper.
  • All embedded DVRs have some type of TV Output, whereas not all PC-Based DVRs do.
  • Takes up less physical space.
  • Does not create noise.
  • Can be hidden and remotely accessed with a remote (remote requires IR repeater).
  • Less susceptible to viruses.
  • Extremely stable and reliable since they contain fewer parts. The software is often written in basic machine code or Linux code which tends to be more stable than Windows software.
  • With an embedded CCTV system you gain the stability (an average of 100 times more stable).
  • Lower hardware and software cost.
  • Smaller mechanical size.
  • Easy to operate.
  • Operations and settings return to previous conditions after power loss resumes.


A PC-based digital video recorder (DVR) is basically a personal computer that has been modified with hardware and software to work as a DVR. An embedded digital video recorder is a machine that has been manufactured specifically to work as a DVR. In embedded DVRs there is typically one circuit board with software burned into the chip.

What is an IR camera?

IR stands for Infrared. Infrared camera is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light. Instead of the 450–750 nanometre range of the visible light camera, infrared cameras operate in wavelengths as long as 14,000 nm (14 µm). It can be used either in daylight or in TOTAL darkness.

What should I look for in a CCTV that is meant for night time application?

You should look for CCTV which is equipped with infrared LED, namely the IR Camera. IR camera enables the users to capture images even in a total darkness.  Infrared Cameras are most suitable for low light areas or total darkness areas. Infrared LEDs surround the lens and shine infrared light, illuminating the scene.  During the day it is able to present colour images, while during the night, images would be black and white.

How many days/weeks of recording can I store?

The recording will have to depend on how many bytes your storage has. For 1 terabyte (TB), it should store at least 1 month’s worth of recording or more.
