A camera mounted infrared illuminator is used with most night vision infrared digital video surveillance and security cameras to provide invisible light that is used to create an infrared digital video. The illuminator is normally aimed in the exact same direction of the camera lens so that it can provide infrared light beams to illuminate the target area. Infrared illumination can be “seen” by the camera, but cannot be seen by the human eye.
What is a GeoVision DVR Security camera? GeoVision is a manufacturer of Internet Protocol or IP security cameras. A DVR or Digital Video Recorder is a device similar to the hard disk drive on a personal computer, in this case used to store digital video files. A GeoVision DVR security camera is an IP digital video security camera that can either be connected to a personal computer using either a GeoVision DVR PC card or via the internet. Perhaps a little background information and a closer look at GeoVision products will help to describe this concept in detail.
A low light in wall surveillance video camera has a multitude of uses. It can be used to monitor your children to ensure their safety and well being; it can be used to monitor an office,; it can be used as a nanny cam to monitor your nanny and child when you are not present; it can be used to monitor individuals that work in your home; or it can simply be used to keep a watchful eye on your important property.
An autofocus CCTV or Closed Circuit Television camera is an ideal choice for surveillance and monitoring when the field of view encompasses large differences in distances of the target or the target is moving and often changes its distance to the camera. Most autofocus CCTV camera lenses are zoom lenses; a variation of this type of lens is a vari-focal lens which can vary its focal length by manual adjustment.
A CCTV camera multiplexer is an electronic unit that is able to combine the video transmission signals from more than one camera into one single channel or transmission. These units are often used where processors, VCRs, Digital Video Recorders or DVRs, and monitors can only handle one input. The multiplexer, also known as a Mux, in essence reduces the multiple camera feeds by creating one output that combines all of the inputs to the multiplexer.
An outdoor motion activated security camera system is an ideal choice for perimeter coverage of a home or business. In addition, motion activation is a conservative, economical choice that produces excellent video surveillance and security results.
Nothing can give new parents the sense of comfort and peace of mind like a child room infrared camera. Innovative technology in the security camera field has produced high-tech cameras with sophisticated features for a variety of uses while maintaining affordable prices. Child room infrared cameras are not only great for use with newborns and infants but with toddlers and all young children. They also work great as nanny cams to help you monitor your child your child’s care giver while you are away.
Wireless 16 camera motion detector security systems are the ultimate solution for digital video camera surveillance and security. The wireless cameras not only provide quick and easy installation, but can be installed just about anywhere. In addition, the motion detection feature provides for conservative storage needs on Digital Video Recorders (DVRs) and if used with the Tilt-Pan-Zoom (PTZ) function can be used to track objects or individuals throughout a camera’s useful field of view.
A battery powered security camera can give you the freedom to install the camera in just about any location, especially if the camera is a wireless type. However, there are a few things you should know about battery powered security cameras before you make a purchase. The following should help to give you insight on how the power supply is normally handled for digital video cameras and the options available for battery powered units.
A wireless outdoor security camera system is quick and easy to install and is versatile enough to be used in almost any environment or situation. Technological advances have created optional features for the cameras that makes them even more useful and for a reasonable price.
A wireless outdoor security camera system may utilize one to several outdoor wireless cameras. Each camera has its own built in transmitter and antenna which it uses to send its video signal to a corresponding digital video receiver. Modern wireless outdoor security camera systems take advantage of the 2.4 or 5.8 GHz radio band technology (the same used for land-line based wireless telephones) for sending their signals.
This technology has various strengths or ranges that it can transmit the video signal. The range for this technology is often referred to as Line Of Sight or LOS. This means that the stated maximum range for the camera and receiver is based on a line of sight from one to the other without any obstructions in between that would occlude the line of sight. Of course, wireless outdoor security camera systems still function if an object is blocking the LOS path, but the range is reduced, based on the type of material. Some outdoor wireless cameras boast ranges as great as up to two miles.
The cameras used in wireless outdoor security camera systems are the same as those used in wireless indoor security camera systems with one major exception. Out door cameras are built placed inside a cover or enclosure that protects the camera from weather and other environmental elements. These cameras are normally rated based on an International Electrical code standard know as the Ingress Protection Code or Rating. The code is designated by the letters IP followed by two digits. Each digit represents a degree of protection that the camera is afforded by its enclosure. Generally, most outdoor cameras are rated at IP66 or IP67; look for one of these ratings when shopping for your outdoor wireless cameras.
An IP66 rating means the camera is dust tight (dust cannot reach working parts of the camera) and that it can also withstand powerful jets of water from any direction. IP67 has the same dust rating, but this rating indicates that the device could be submerged in up to one meter of water without causing harm. There are a variety of specialized outdoor cameras designed for protection from damage from humans as well as other factors. There are even wireless outdoor security camera systems that are rated to be able to survive explosions.
Wireless outdoor security camera systems are quick and easy to install. Since there is no video transmission cabling to install, just mount the camera and plug in the power supply and it’s ready for use. After all the cameras are in place, the receiver is setup to receive the cameras on the proper frequencies. The receiver passes the video signal over to the processor and Digital Video Receiver or DVR.
There are several optional features available for wireless outdoor security camera systems. The following is just a partial list of some of the more common options you may need:
• Day/night vision cameras that can capture video in very low light conditions
• Night vision infrared cameras that can capture video in standard lighting conditions as well as conditions of total darkness
• Cameras can record audio and video
• Pan-Tilt- Zoom functions that increase the useful filed of view of the cameras. These cameras when equipped with the proper programming software can use motion detection to track and follow individuals or objects (like cars in parking lots)
• Some outdoor cameras can be purchased that use rechargeable batteries instead of an AC power adapter supply. This eliminates the need for a power supply line to the camera
• IP (Internet Protocol) Ready Cameras that can be networked on the internet
As you can see, technology has made the wireless outdoor security camera system incredibly versatile, quick and easy to install, and economically priced as well. Regardless of where you need to place your camera or what you need your camera for, there is a wireless outdoor security camera system that can do the job.
Innovative technological improvements have made it easier than ever to make your CCTV camera remotely monitored. There are basically two types of Closed Circuit Television (CCTV) cameras, analog and digital; and both can be installed for remote monitoring.
There’s nothing like a security and surveillance system with quality outdoor security cameras. A good quality camera is rugged and well protected from the elements, yet sensitive enough in function to produce a video image with only the slightest amount of light. Quality outdoor security cameras need to be maintenance free as well, since these cameras are often mounted high atop poles, buildings or other difficult to reach locations.
Some of the most popular security surveillance systems are the wireless security camera with DVR systems. It’s not hard to understand why these systems are in demand. They are simple and quick to install, they are a complete standalone system with great versatility that lends them to almost any application, and they are affordably priced.
As people discover the benefits of multiple camera wireless security systems, they are becoming ever more popular. Innovative technology has provided additional optional features for these systems making them incredibly versatile in application without making prices skyrocket. In fact, multiple camera wireless security systems can actually save you money by eliminating or keeping security department staffing at a minimum.
