The questions you have to ask before choosing your video surveillance camera are mainly four:
· what is the place to keep under control? Internal or external?
· what is the budget to be allocated to the purchase?
· What is the degree of accuracy of the camera you are looking for? Do you want to analyze faces and small details? Or do you want a broader overview?
· will the cameras be visible or hidden?
