As you go about purchasing CCTV, keep in mind the specific needs of your home or company. What is the purpose for your CCTV? The more you know about your goals, the more specific you can be when talking with a CCTV vendor.
One question is whether you will want to monitor the video footage. In other words, do you simply want to record the video footage or do you want to be able to monitor it as it is being recorded? Another option is to hire security companies who will monitor the live video footage for you.
Next, you want to think about the cameras themselves. How many cameras do you want? Where do you want to install them? Do you want fixed or movable cameras? Do you want to record in color or in black and white? Do you have a monitor to playback material? In many cases, you will need to buy a lens separately, so think about how much detail you want in your recorded images.
Finally, begin contacting surveillance vendors. When talking with the vendors themselves, make sure you understand how much you are paying and what you will receive for your payment. Is service included? What equipment is included? Do they offer monitoring contracts? Can you tie all your cameras into one network with burglar alarms and other security measures? Compare prices with more than one vendor, and ask friends and companies who have CCTV what they would recommend.
