Cameras and Motion Sensors – Setting up Wireless Computer Controlled Security Camera System
While with a camera based surveillance system, you can always keep an eye on what is going on at your home or other premises, it requires you to keep an eye on the Internet enabled device that serves as the display. Chances of missing something important are always there if you take your eye off the display, though you can rewind and watch the video in case of any unpleasant event. Motion sensors are a step further. They keep on sending out infra-red waves at definite frequencies. If anything disturbs these waves, the motion sensors send out an alarm. It can be a sound notification that plays on the display that you are using for surveillance. It can also be an on-premises siren to scare off robbers or sends an alert to the nearest police station.
You have to consider a few questions before placing the cameras or sensors:
- What object/area are you trying to safeguard?
- How much area do you wish to cover?
- What kind of lighting is in the area?
Based on the above questions, you will need to check out the cameras that you will be purchasing. For example, if the lighting of the area changes frequently (example, you wish to place it outside to guard the gates), you need to buy a camera that has an Auto Iris. Similarly, if the light is always low at the area, you will need a camera with better Lux Rating (to see better in dark).
Once you have decided where to place the cameras, you need software that helps you connect these cameras and sensors to your computer. The software should also be able to send the images either to a fixed display, or to a roaming one – a smartphone, laptop, netbook, etc. Naturally, you won't be able to see all cameras at a time. The wireless computer controlled security camera system software has functionality to switch to different cameras as you select different areas under surveillance. Most of the times, you just need to change the name (actually the IP address of the camera). If you are also using sensors, you need not worry about them. They'll send you alerts only anything disturbs the radio waves. You can accordingly change the surveillance area and check out the reason for disturbance.
Thus, if you intend to install a wireless computer controlled security camera system, I recommend using motion sensors as well, so that you get instant alerts. This helps if you forget to check certain areas and offers you more peace of mind.
