How to choose a Video Surveillance System for Your Home?

The need for security at home and office and the monitoring over the employees at the workplace are the main reasons why people are looking up to a video surveillance system. Every individual wishes to keep their goods, property and his dear ones safe enough. These security systems not only capture images and videos, but can also be used to watch the live footage of any suspicious activity taking place.

But, are all the surveillance systems the same? Like every other technology, here too there are a number of factors, one would need to consider before investing in the entire system. These factors are the basic ones that will help people to know what they really need. Its only after you are clear with this, that you can move on to the next advanced features you wish to consider about the camera. Let us take a look at all these basic features one by one.

IR Security Camera

  1. The Place where the Cameras would be installed: This is extremely important as you need to know the kinds of cameras that you will have to invest in. Indoor cameras are quite simpler as compared to the outdoor ones as they are used for normal capturing of images and videos and come without weather proofing. The indoor cameras are also quite cheaper as compared to the outdoor ones.
  2. The Kind of Camera you want: There are two basic kinds of cameras; the Black and White and the Color ones. You can select any of these as per your requirement. The Black and White cameras allow you to install a surveillance system at a lower cost. Moreover, these cameras give excellent results in dim light. They are best used at restaurants and outdoor night monitoring. They also respond well when IR Illuminators are being used along with them. However, it is good to have at least one colored camera around as it is ideal for positive suspect recognition.
  3. Stationary or Potable Cameras: You need to decide whether you will need to move the cameras now and then, or you would simply let it remain where it is being installed. The wireless cameras offer great portability making sure that the camera can be uninstalled and reinstalled easily. The Wired cameras add in a little more complexity in the process of installation. The wired ones are cheaper than the wireless ones.
  4. You wish to watch it Live or just Record it: You will want to take the live footage of the activities taking place in areas where immediate response is required. The examples are hospitals and child care. Whereas, in places where you need not respond immediately, you can prefer the recording of videos.

Apart from these, you can also consider the points such as the range of the cameras, the lens used, the image quality, etc. There are many more such factors that one would like to consider. But, those factors would only keep adding to the cost of the system. If you just need a simple

The need for even illumination for Network Cameras

We all have known the importance of installing night vision network cameras to obtain better images and footage during the dark. It is during this time that the cameras are capable to capture things that are not visible to the human eye. Images are better captured with the use of the IR Illuminators installed along with these cameras. These illuminators are mainly used for the Infrared light that they provide so that the cameras can capture a clear image. This light is invisible to the human eye and thus does will not give an idea about a camera being installed in a place.

The clarity of the image or the video footage obtained highly depends on the kind of IR light emitted by the IR Illuminator. You will rather prefer buying a camera that provides high resolution images. But, higher the resolution of a camera, more evenly distributed the light has to be. These cameras will not be able to capture an image if the IR light from the illuminators is focused in a single direction. The light emitted by this device needs to be focused evenly throughout the range of the camera.

Consider a situation that you are driving a car on a highway. It is pitch dark and you can only see the road and a little more because your headlights are on. Suddenly a car is coming from the opposite direction that also has its headlights on, will cause disturbance in your sight. This is because the light was quite evenly distributed while you were alone, but later as another car appeared, a flash of light coming from a single direction will suddenly prick your iris. This will affect your vision for a while. This is a similar case in cameras as well.

Cameras with a lower resolution give out images that are made of less number of pixels of larger size. Whereas, the high resolution images obtained are the ones that contain high number of pixels, each made up of a smaller size. The larger the pixel, the more it can capture an image. The smaller the pixel, the more amounts of minute details are required. Hence, the quality of lighting may affect these too. Larger pixels may not need even distribution of light, but the smaller ones will need enough of light to be distributed in each of them. Thus, even distribution of the IR Light is required while we expect a network camera to give out clearer images.
