Achieving Clarity in CCTV Contracts
- When designing and installing CCTV systems it is an important function to have the subscriber approve in writing upfront, each of the viewing areas of the installed cameras that you install, before permanently mounting same. This is best achieved by using a video test monitor, which helps minimize customers stating afterwards that they are unhappy with the video image and/or the installed location of the camera.
- To the extent cameras you install at a protected premises do not pan, tilt, zoom or auto-focus it is crucial you note the aforementioned within your contract so that there are no ambiguities or misunderstandings with your subscriber.
- Never use verbiage in your proposal or contract regarding the camera capabilities you install that are unrealistic. Examples would be: the cameras provide crystal-clear imaging; the cameras can see with no surrounding light; and/or that the cameras will be able to identify a perpetrator(s) in every instance.
- Also notable in the fine print of your contract should be a disclaimer that the cameras you install do not see through fog, snowstorms and other uncontrollable weather-related conditions.
