Camera Placement
![Page 19: Bus Surveillance System](https://reader035.vdocument.in/reader035/viewer/2022062300/563db9e2550346aa9aa0ce22/html5/thumbnails/19.jpg)
How Many Cameras? The number of cameras
is usually prioritized by desired system results and available budgets.
Recent trending is that most agencies have 5 to 6 cameras per 40’ vehicle installation.
1 or 2 cameras are used for outside viewing of the vehicle.
Additional considerations
![Page 20: Bus Surveillance System](https://reader035.vdocument.in/reader035/viewer/2022062300/563db9e2550346aa9aa0ce22/html5/thumbnails/20.jpg)
Lens Considerations
Camera lens sizes vary from 2.9MM to 16MM
Proper lens selection provides investigators with recorded images that have good proximity for image objects and good field of view.
For inside the cabin (4,5 & 7) lens sizes are usually 6MM or 8MM. Stairwells (6 & 2) usually are 4MM.
Outside cameras can vary depending upon application with considerations including license plate recognition, grade level crossings and intersection traffic.
