In the past surveillance was always conducted by patrolling security personnel who are on the lookout for criminal activity. Human error, focus on cost effectiveness and the fact that patrols cannot be everywhere all the time, have created a need for video surveillance.
There are only 3 reasons to have a CCTV system:
- To have a visual record of an incident for prosecution or future incident response
- To obtain visual information about an incident or situation that is currently taking place
- To deter any activities that you or your organisation find unacceptable
A camera is not just a camera. When buying a CCTV system it is important to specify the function of each and every camera. This is important and not something to be rushed as it will ensure the appropriate ROI because a system that is designed to meet a specific need performs long after the technology may become obsolete.
We can basically say that we are writing a mission statement or job description for each camera.
You can determine the requirements by answering the following questions per device:
- What is the purpose of the CCTV system as a whole?
- Are there requirements for real time monitoring or should video just be recorded for review at a later stage?
- What is each camera viewing? For what reason?
The function of the camera means that you will need to use different lenses and technologies to create specific fields of view.
Three factors will help you decide what lens to choose:
- What is the target? Is it a person, a group of people, a specific package or packages, vehicles or the global overview of a parking lot?
- What activity are you trying to observe? Is it theft, robbery, assault, trespassing, or package unattended?
- What is the purpose? Is it to view a fixed area, in which case a static camera is sufficient, or do you require a specific PTZ (pan tilt zoom) that can be controlled by an operator to do visual assessments and video based patrols?
