There are many different types of security cameras on the market, ranging from high-end, high-tech cameras employed by the military and various industries to the more economical versions often seen in convenience stores. These cameras are designed to meet different needs and environmental conditions.

Type of Cameras:

  • Day/Night Cameras - are designed for use in outdoor areas but can also be used indoors areas with poor lighting. Day/Night security cameras will provide a color picture during the day, when light is good. As night falls, and it gets darker, the camera will switch to black and white for better night time viewing. Day/Night Security Cameras have an extra sensitive imaging chip that allows it to capture a good picture in low light situations without using infrared lighting. This works well in areas that have street lights outside or an exterior light that can be left on at night. Keep in mind that cameras without infrared lighting will not capture an image with zero light.
     
  • Infrared Cameras - sometimes referred to as night vision cameras because of their ability to capture video in complete darkness, Infrared cameras use a infrared LED light installed on the outer lens of the camera. This allows the camera to capture and record images in the absence of light. Any object that has a temperature can be detected by infrared. Humans aren't able to see infrared light because it lies outside the range of visible light the human eye is able to detect.
     
  • Wireless Cameras - by nature, wireless cameras are very flexible; they can be placed anywhere without worrying about "wiring" them. Wireless cameras work via a transmitter and receiver device, unlike regular cameras, which require two wires, one for power and one to transmit images. Images can be relayed to a portable DVR device for completely wireless recording. Some wireless cameras run the risk of having interference from certain devices, such as cell phones, fluorescent lighting, microwaves and wireless internet devices. Another risk is the possibility that you video feed could be intercepted by others. When used right, wireless cameras are a very flexible and powerful surveillance/security camera.
     
  • Dome Cameras - One of the hottest trends in the video security industry is the use of the security dome camera. Versatile and unobtrusive, dome cameras are easy to mount anywhere. Many dome cameras have smoked or blackened coverings so there's no telling where the lens is focused. The dome itself offers protection from both the elements and vandals. CCTV dome cameras come in all shapes and sizes, and are available in day/night, infrared, weatherproof, and vandal-proof models. There are two main types of dome cameras, fixed and PTZ. Fixed dome cameras stay in a single position, whereas PTZ cameras the ability to zoom, tilt and pan.
     
  • Pan Tilt Zoom (PTZ) Cameras - These cameras get their name because of their ability to pan left and right, tilt up and down, and zoom in and out. They can do this due to a combination of a pan/ tilt head and a zoom lens. PTZ cameras are made for both outdoor and indoor applications. Outdoor PTZ cameras usually are weatherproof, heavy duty, and more robust than their indoor counterparts. Indoor PTZ cameras, not needing to endure the harsh elements, often employ lighter housings. A trend in the security industry is the popularity of PTZ dome camera. PTZ dome cameras operate in the same manner as traditional PTZ cameras but differ in that the camera is encased in a dome. PTZ dome cameras have several advantages over traditional PTZ security cameras. Domes can be darken or smoked to prevent telling where the lens is focused. Also, they can efficiently move in all directions, including 360 degree rotation and viewing straight down. PTZ security cameras are perfect for scanning large areas, zooming in on specific objects, and tracking movement across the scanning area.
     
  • IP Cameras - A network camera is connected to a computer IP network. Cameras capture analog images that are then transformed into digital images and streamed over an IP network via an Ethernet cable. Network cameras are broadcast over the Internet; however, each camera has its own stream and IP address. To view and record a feed, separate software must be installed. These network IP cameras allow you to monitor and surveillance your home or office anywhere in the world. An IP camera is a useful tool in ensuring security to your property and valuables, and an IP camera is designed to provide you with top security for your specific needs.
