Analog CCTV System

Analog CCTV System has been in existence for many years and is commonly used in many application. Its attraction lies in the lower cost, the wide variety of cameras as well as the ease of implementation and usage.

  • a Digital Video Recorder (DVR) with hard disk for storage
  • analog cameras such as dome, IR dome, IR bullet or body camera
  • accessories including power adaptors, power supplies, baluun connectors and TV monitors

All of our analogue CCTV System can be linked to the network and allow you to view remotely on a laptop, desktop and mobile phones.

Digital Video Recorders (DVR)

Digital Video Recorders (DVR) record video images captured by cameras and stored them digitally on hard disks. There are 2 types of DVR, They are:

  • Embedded DVR
  • PC Based DVR

Embedded DVR comes complete with its own proprietary operating systems, Graphical User Interface and display capability and may include interface for mouse, panel and remote controller. It is typically equipped with at least one USB port for backup to thumb drives or other portable external hard disks.

PC-Based DVR are really personal computer installed with system specific video captured cards. The Video Capture Card may support 4 or 8 cameras, and will take up 1 PC Slot. A dedicated DVR software is installed, running on Windows or Linux platform.

Embedded DVR has greatly increased in its processing power in these past years that they have massively outstrip the PC-Based DVR in many applications.  PC-Based DVR are currently used only in large installation where they need videos to be kept for more than 90 days and they need the additional processing power of the pc to perform storage back-up.  And even then for such application, the customers may opt for a fully IP system instead.  So while we still see some applications with PC-Based, it is really in the decline.

Embedded DVR

We carry a wide ranged of embedded DVR.  Depending on the number of cameras you need, you can opt for:

  • 4 Channel DVR - maximum 4 cameras
  • 8 Channel DVR - maximum 8 cameras

Surveillance Grade Hard Disk

seagate surveillance harddisk for cctv systemDepending on the model selected, each DVR can support 1, 2, 4 and 8 hard disks.  How many hard disk you need and what kind of size depends really on how long you needed to keep the data as well as how many cameras is needed.

For a typical home with 4 cameras, a 500 GB hard disk is adequate for storage up to 1 month.  

We use only surveillance grade hard disk.  Unlike the normal hard disk in your computer, the hard disk in your DVR is expected to work 24x7, reading and writing every second.  It needed to be hardier and more rugged than normal hard disk.  Hence the cost is higher than normal hard disk. 

Even with the surveillance grade, it does not mean that the hard disk will not fail.  To ensure data integrity and no loss of video, it is good to replace the hard disk once every 3 years.

CCTV Cameras

Compared to cameras of previous years, the modern cameras are much smaller, sharper and cheaper. With advances made in technology and improvement in manufacturing, there is now so wide a range that it is impossible to include every variety of camera on this web site.

Hidden cameras are fast becoming popular for household surveillance and can be built into common household objects such as motion detectors, smoke detectors, clocks and photo frame. While it is ideal for catching the action, it does not deter crime and in some cases, may raise privacy issues. Hence it should be used only under special circumstances.
