Security Cameras vs Surveillance Camera’s – Pros and Cons Explained

There is a big difference between Surveillance Video Camera Systems and Security Camera Systems. It all comes down to the way you use your CCTV System. A Surveillance System is one you would typically see in the large stores, shopping malls, casinos, airports, sport venues, etc., – basically, anywhere there is a security guard watching cameras in real time.

Use of Pan Tilt Zoom Cameras (PTZ Cameras) could be very beneficial for Surveillance Systems. Security guards controlling PTZ Cameras can readily pull up all the details he or she requires to properly judge the situation and prevent instances such as shop lifting, property damage, robberies, etc. In other words, Surveillance Systems are used to act on the spot rather than after the fact.

There are few major differences in design of Surveillance System and Security Camera System. One, and probably the most important difference is that with Surveillance System we can actually use less cameras and have less detailed view of the area than with Security Camera System. Since we will usually act on the spot, there is no need for positive identification on the video footage. There is no need for close up facial shot or license plate camera. Simply, when a security guard sees something is not right, he can approach the suspect and request identification or hold the person for public protection or police to arrive. The same thing applies to the identification of vehicles. Surveillance Systems should also feature real-time display.

Security Camera Systems are an entirely different basket of eggs. Since there is real time, active monitoring, video footage will be used to try to identify the person, car etc. Thus, there is a need for much more detailed picture. Cameras located in very specific areas should be focused on obtaining as much details as possible. Examples thereof would be cameras located in elevators, at the exits and entrances, focused on capturing faces of people or vehicle license plates. The more detailed picture the easier it is later to use video footage as evidence in court.

Remember that not all cameras in Security Systems need to get every detail. If it is possible to catch the person’s face at the entrance, than the rest of the cameras are used only to track person’s movement and activity; the same thing applies to vehicle. If vehicle’s license plates are captured at the gate, and then again on the wide angle camera of the parking lot we see this car hitting other parked car, that picture does not need to show explicit detail. As long as we can track this car from the moment it enters the parking lot to the moment it hits other vehicle, this is all we need.

It is important to have a time stamp on every static picture, and if using more than one DVR, time on all DVR units must be synchronized. Real time display is not really important in this case, since there is nobody there to watch it live.

Since there is a difference between Security and Surveillance CCTV System, it is important to consider it when choosing the way you secure your premises. Camera locations, Camera Lenses and PTZ option along with Real Time Display DVR are the most important factors to consider.
