Megapixel cameras reduce security costs for retail and forecourt sites, writes Gordon Smith, Managing Director of GVD.
Megapixel cameras work harder than analogue cameras as they cover a wider field of view and retain a sharper quality of picture even on recorded footage and when zoomed in. For retail car parks, shopping malls or retail chain stores megapixel cameras give you more flexibility to survey a larger area using less cameras and less money. Image quality is high, leading to easy identification of people and a clear view of commercial transactions. In contrast to DVRs where the playback capability is often lower than the quality of live recording, the image quality you get from an IP solution remains consistent over time.
Retail chains can save money by bringing all video surveillance back to one central control room for monitoring where a security team can access and act on video information rather than having one dedicated CCTV control room at each retail outlet.
The picture above illustrates how one IqinVison Sentinel Proline 5MP camera can do the work of 10 analogue cameras. As you can see when zoomed in the quality of the picture is retained so that you can read the registration plate on the car. To get this image from an analogue camera you would need it at the car level and positioned directly at the registration plate. With one 5MP camera you are able to get a wide view of up to seven lanes of cars. – imagine the savings in a Forecourt solution for this. You would save on installation time, cable costs, cameras and ongoing maintenance.
Forecourt options:
IP solution
1 x 5MP IQinVison Sentinel Camera
Use 1 channel on Milestone NVR
1 single CAT 5 cable for data and power
Maintenance – 1 Camera
Efficiency – One camera to view for playback.
Analogue solution
10 coax cables for cameras and 10 local power supplies
Use 10 channels on DVR
10 x D1 resolution analogue cameras
Maintenance – 10 cameras
Efficiency – 10 cameras to view for playback.
Now, ask yourself the question is an IP security solution really more expensive than an analogue solution?
