Surveillance cameras are an important part in maintaining the security of a business or a home. They reduce the likelihood of crime. High quality security cameras can be installed to keep away illegal activities. They can also help provide valuable feedback about employees and monitor their activities. Installing the cameras can be done by an expert. When buying surveillance cameras several factors are considered:

a) Indoor or outdoor requirements. Most outdoor cameras can be used for indoor. An outdoor camera should be weatherproof (tamper-proof and built with an exterior metal casing) so as to withstand extreme temperatures rain and heat and damage.

b) Lighting. Consider whether the camera will be used day or night or in a well-lit area. Day/Night cameras switch to black and white when the light is low.

c) Desired angle. For a wider angle perimeter view, consider a lens that have a shorter focal length. A longer focal length makes a single object occupy most of the field view.

d) Resolution. Sharp images results from a high resolution. Consider the resolution of the surveillance camera for better images.
