Security cameras are not a luxury. They are a necessity. If something happens in your business or home where the police are involved, the first question they ask you is if you have a camera system. If your answer is no then you get relegated as crime documentation rather than crime investigation. Criminals, vagrants and bullies are less likely to commit their atrocities in an area where they notice cameras.
No camera system is worth anything if you cannot use the equipment effectively. Hull Productions sells and uses the easiest camera system in the industry.
IC Realtime and Speco Camera Systems offer the best bang for the buck while being the easiest systems to retrieve and backup incidences.
