What safety camera should I pick? How will I put this down? Questions like these have to be addressed if you decide to make your home or workplace healthier. Here we will do an overview of exactly what you need to know in order to pick the right security camera for your installation needs and to know the best location. Mammoth Security Inc. New Britain offers excellent info on this.
Choosing the best camera
For various reasons cameras have different features. If the area and items to be under surveillance are determined then the camera features must be decided next to better match the organization’s security needs.
Set, or Pan, Tilt, and Zoom (PTZ)? Have you ever got the impression when you step into a building that someone was watching you? How about just taking a look at you? Look up and you could see one of two cameras: Fixed or PTZ. The fixed camera is just looking at a single angle. The PTZ camera will scan the scene with movements such as up and down, left and right, zooming in and out. Compact cameras are cheaper ($200 to $500 for fixed versus $2000 or more for PTZ), and are thus used more commonly. Fixed cameras are normally not tracked on a regular basis although generally PTZ. PTZ cameras are often widely used to track the cameras from a central control room when security personnel are inaccessible.
Digital Image or Megapixel? Think about the image quality of an HD television compared to the image quality of the television you were used to when you were a teenager, and think of the image quality of the films today compared to the image quality only 10 years ago. Enhancements from normal to high-definition camera quality mean that smaller objects in videos can be detected and used as evidence or indicators during a surveillance video investigation. Approximately 4 percent of surveillance video cameras sold in 2008 were high-definition but due to the image quality. High-definition cameras are constantly being used by organisations. Surveillance cameras can have a resolution of up to 16 megapixels while a high definition television has a maximum of 3 megapixels.
IP or analogue? The disparity between the two is the same between a videocassette (analog) recording camcorder and an all digital camcorder (IP). Although it is possible to transmit all forms through a network, an analog camera needs an adapter to do so. One big benefit of using IP video surveillance cameras is that only IP cameras can have megapixel resolution. However, most thermal and infrared cameras are available in analog form only. In the video surveillance market, IP cameras are rapidly replacing analog cameras and currently represent around 20 percent of those sold.
Colour, Infrarot or Thermal? Color can be useful in low lighting for surveillance cameras but this is just about the only time. In this case it would be beneficial to have an infrared or thermal camera, as they produce black and white images. Black and white images as color images would not blend together in the dark. Color cameras would therefore be better suited for daytime or well-lit areas monitoring. Infrarot or Thermal are more suitable for darker areas. Infrared cameras use infrarot illuminators to produce a clear picture. Such special lamps make infrared cameras considerably more costly than color cameras, like 2 to 3 times more. Thermal cameras are much more expensive, and can cost between $5000 and $20,000. These cameras create outlines of objects and require no illumination, and will be perfect for areas such as in the middle of the desert or forest.
Place, position, place
A key aspect of surveillance is the security camera, and its location is as important as the security camera itself. It would be as successful to place the camera at the wrong position as placing a blindfold over the lens. A camera has the very function of surveying operation and protecting land. While positioning a camera one needs to consider the security assets and all potential ways in which people can reach the secure area, known as chokepoints.
Assets: Cameras should be mounted at those places where the important assets are most easily shielded. There are objects and areas essential to a specific company or organization. Areas of goods, safes, costly art walls and expensive equipment are only a few examples of properties. Often known as assets are the areas where important operation happens, such as parking lots, checkout counters, and lobbies.
Chokepoints: These are all possible ways to reach a given area. Cameras strategically located at these points of entry allow for a cost-effective surveillance network. Types of chokepoints include driveways, doorways, doors, rooms, windows and even open chimneys.
