There are a huge number of factors to consider when choosing the right surveillance camera for your needs. Each situation will require a different surveillance camera, for instance if you want to film an outdoor area with CCTV cameras, you will have to know if you want to record both day time and night time, in which case will the area be lit at night enabling you to see? If not then do you need to install lighting or do you go for a surveillance camera that has IR or a camera that has a large dynamic range? meaning that it can adjust for dark areas to make them lighter so that you can see what is being recorded rather than seeing a black image.
Here is a list of camera elements that you need to consider when making your decision:-
- Camera Resolution – Resolution is the number of pixels in the image that is recorded. The higher the resolution the more information that is captured.
- Bandwidth – If you have chosen to implement an IP surveillance network you will need to make sure that you dont overload the network with data.
- Power – Does the camera need a power source or can you provide power over the network, this is otherwise known as POE.
- Field Of View – The camera can have a wide field of view which means it will see a large area, or it will have a narrow field of view, generally for focusing on a specific area.
- Dynamic view – The amount of light that the camera can capture can have a huge impact on the image, if there is a lot of light in the background the foreground image might appear black and therefore obscure a face/details on a camera with a low dynamic field.
- Video Compression –
- Housing –
