Nowadays, it has become a trend by homeowners to set up a home security camera in order to have a secure home. Being unfamiliar with such devices may seem to be complex in terms of installation and technicality. However, the setting up of a video surveillance in this modern time is no longer a complicated task to achieve and is as easy as installing a home entertainment system. This topic will discuss how home surveillance systems came to be a major instrument in security, the features and advantages in owning one and basic information on each part’s basic functions.

Keeping track of events in a particular area is the main purpose of a video surveillance. Once a video has been recorded, it will then be sent to a viewing screen and the data registered on a storage device. Such video recordings are very helpful in the prevention or interruption of criminal acts and can assist an investigator in the identification of crime suspects. The first ever documented function of a video recording was in 1942 when the launching of V-2 rockets were being monitored and recorded.

The CCTV or closed-circuit television is the use of video cameras to transmit a signal to a specific place. The video surveillance camera was first implemented in Olean, New York in which purpose is to capture recordings on illegal street activities. After crime investigators have found ways on how to catch wanted criminals using security cameras, it has become a sought-after utility in businesses and even homes as a security camera can intimidate lawbreakers from pursuing an illegal activity.

The basic components of a home surveillance system consist of a security camera, transmission device, monitor, and recording device. However, these components can be used to make a simple system or a versatile and complicated system. Cameras can be used indoors or outdoors, and different lenses are designed for different applications and functions. Lenses are defined by their focal length and field of view. Focal length determines how clear something appears to be at a distance, while field of view determines the size of the area captured by the camera. While cameras are available with pan/tilt/zoom functions for more control, fixed cameras with a standard focal length and field of view are plenty for a home security system.

The feed from the security camera can be transmitted through coaxial cables, fiber optics or a network connection. The former is generally preferred for shorter distances, while the latter two options work better for longer distances. All connection options work well, so homeowners can choose whichever type they prefer.

Viewing screens are manufactured to accept video signals only and can reach a size of 17 to 52 inches. Users can view diverse on a single screen and can cycle between different camera feeds at the same time. Experts on video surveillance recommend digital video recorders for the reason that they acquire and record footage at an excellent resolution making it easy to spot a specified footage.

Find the right security cameras for your security camera needs. They can help in the protection of your household or organization with little to no cost to you. Recent reports often show that security cameras greatly reduce crime levels.
