Security cameras give you the ability to monitor any or all activities occurring outside or inside your home or business 24/7. To capture images at night, infrared security cameras are equipped with detector chips that are sensitized to detect near or visible-infrared radiation. Infrared security cameras transmit clear defined video images directly to monitor screens whether it is semi-dark or completely dark. Equipped with the technology to tilt capture, pan and zoom, security cameras work even better than the human eye due to their ability to offer real-time, factually objective images of intruders. This gives the law enforcement authority the info they require to quickly find the burglar and make an arrest. Types of Security Cameras There are two major types of security camera systems: Analog cameras and Network cameras (sometimes called IP security cameras). Analog Security Cameras Analog security cameras are connected directly to a Digital Video Recorder (DVR). The cameras are connected to the DVR using transmission cables. The DVR acts as the heart of the system. It receives video images from the camera, compresses it and stores it on the hard drive to be retrieved later. Modern DVRs also convert analog videos to digital format and are able to stream the video over the internet using an inbuilt web server. The DVR is the intelligence behind the camera and is responsible for all alarm inputs, notifications, schedules, motion detection and much more. Network or IP Security Cameras Network security cameras are very different from analog systems since each camera does the work of the DVR. Generally, a network camera is a standard security camera that also compresses videos, converts the video to digital format and streams it over the Ethernet or the internet. Since video images are compressed and converted to digital format at the camera, the camera can stream video images over a network to a PC or a network video recorder that will record the compressed video. Some top benefits of network security cameras are that is possible to add additional cameras to the network and that the cameras and easy to install. How to Install Security Cameras For efficient results, it is essential to set up your security cameras properly. If you do not have any experience with electronics, it is recommendable you hire a professional to do the installations on your behalf. Most security cameras are not complicated, and thus, you may be able to install the equipment yourself. The location of the camera's lens is vital. The distance between the subject and the camera should be considered carefully. Ensure the right areas in focus and clearly visible. If you are installing the camera on a structure or wall, ensure it is mounted properly so that it won't shake and distort the image. Remember to mount an appropriate weatherproof casing on all outdoor cameras to protect them from harsh elements, tampering, and vandalism. These are just some important details you should know about how cameras work. Installing the right security cameras allows you to protect your home or business from criminals, discourage criminal activity within their visibility and help deter employee pilferage in organizations. Surveillance cameras may also enhance employee productivity by discouraging unnecessary downtime.
