How to Choose a CCTV System

Your selection of cameras and DVR largely depends on your application and budget. 

If you are looking for a CCTV System for your home, most likely you will use dome cameras as they are smaller, less intrusive or threatening and esthetically designed, and can fit in easily in your living room, dining room or hall ways.  For your porch, walkways and back yard, you would normally use Infra Red Bullet Cameras as they are weatherproof and cost less than Box Cameras with its lenses and housing.

Most homes may need only 4 or at most 8 cameras, making the Embedded DVR the cost effective choice.  The Embedded DVR is also easy to use, has limited functions so there is no fear of messing it out, and sits in your living room like a DVD player.  It can be linked to your internet, allowing you to view the cameras over the internet on a computer or laptop, and over smart phones like IPhone or Samsung's Galaxy.  Most of these DVRs have Apps online which you can download to your hand phone.

If you are looking for a CCTV System for the office, the configuration would be quite similar to choosing for a home.  Depending on the size of the office, you may need up to 16 cameras.  Embedded DVR can handle up to 16 cameras.

If you are looking for a CCTV System for a retail shops, the only difference may be using adding a box camera with zoom in lens to watch the cashier counter.

If you are looking for a CCTV System for a plant or commercial building, depending on your requirement, you may use Speed Dome Cameras, Box Cameras for exterior perimeters, and PC-Based DVR as you may have more cameras, and need tighter surveillance and specialised functions.
