If you are thinking about investing in a CCTV system for your home or business, don’t be fooled into thinking that one size fits all. It is just not the case. With lots of systems being bought over the internet now, you will want to be sure that you are educated about the system prior to shopping so when the salesperson starts asking you questions, you will know what he is talking about. Here are a few things to know prior to starting your search for the right system.
1. What am I trying to cover- Before you start shopping, you will need to think about what you are trying to accomplish with this system. Am I just trying to cover entries into my home/business, or am I trying to cover outlying areas too. If you are trying to cover outlying areas, that is going to be very important to give the person assisting you. Take a look around and try thinking like a thief. Where would I hide, how would I approach the door, etc. This will help make sure you have all your bases covered.
2. The next thing is where my focal point? Find a distance you think would give you the best coverage and measure that distance to give you a reference to choose lens sizes.
3. Next would be resolution- The higher the number of TV lines on an analog camera, the better the picture will appear on your recording. Also take into account how much lighting is available at night. The more light you have available, the better picture you are going to get. It might just be worth adding some landscape lights to maintain that color picture all through the night instead of having the picture turn black and white.
4. Another thing to consider is leave room for expansion. When most people set their system up and running they realize that they missed an area or wish that they could add just one more camera. Thinking ahead will help with this but having the capability to add another camera or two down the road could really help you achieve your final goal
