We use Closed Circuit Television Cameras (CCTV) for surveillance, security, property protection, monitoring employee performance and to monitor areas that may be deemed unsafe for human habitation. The output of these cameras is feed into a security digital video recorder (DVR). This DVR can store the video for viewing later, feed the video into a security center or connect to the Internet for viewing from anywhere in the world on your computer or smart phone. This gives great flexibility to view your CCTV network now, in real-time, from your office or workplace or have a time stamped recording of the video for use later. The Security DVR can be a stand-alone unit with ample recording space or the DVR can very small and integrated with the camera and the recording done on a memory card.
In choosing a CCTV system the home owner or business owner may have different needs and preferences. The business owner may want to spend the time, effort and money to install a wired system incorporating not only video, but also power cables. Home owners may not want route wires through walls and they may want to take the CCTV system with them to a new home. The home owner would then select a wireless system that is easier to install or relocate.
When selecting cameras for a CCTV system we have many choices, and most of them have specific uses for specific conditions.
Indoor Cameras are the most common CCTV camera and are used in offices, homes, schools and retail establishments. An indoor camera can be either wired or wireless and color or black and white.
If security is required around the clock or 24 hours a day we can use Infrared Day/Night Cameras. These cameras can record in daylight, but also in almost complete darkness. To ensure a good image these cameras utilize infrared LEDs that illuminate the area or subject, but are not seen by the human eye, so the intruder will not know they are being recorded.
The Dome Camera has a small camera placed in the dome-shaped housing. The camera can be aimed toward a specific area or adjusted for a wide field of view. The dome camera is usually placed on a ceiling, but can be placed on a wall or even the floor as desired. This camera is good for view a large area with lots of people and the camera is very discreet.
