The strong sunlight outside caused issues for cameras without WDR, making details of cars entering and exiting the parking garage difficult to discern.Īt night, the cameras all stayed in color mode due to the illumination inside parking garage.Īll cameras were tested with H.264 and minimum exposures normalized to 1/30s.

The rest of the cameras first notice the car once it enters the shadows of the parking garage roof.Īt night, all cameras remain in color mode due to the abundant illumination provided inside the parking garage. We can get a better view of the driver dependent on how each camera handles the car's front headlights.Ĭameras were mounted at about 8', aimed at the entrance and exit lanes of the parking garage. This location allowed us to view cars exiting the parking garage from the top level, facing forward.ĭuring the afternoon with clear skies, cameras with strong WDR performance are able to capture the vehicle moving into the scene from the top. Inside the parking garage, cameras are mounted ~7' high due low ceilings. The wind was still very active at this time, so slight sway can be seen in the clips.Īt night, street and building lights provide bright but inconsistent lighting. Cars are traveling ~30-45 MPH here, and we can see further down the road.ĭuring the afternoon with clear skies, we get a good look at a parking lot and a few buildings in the middle ground.
Similar to our eastern shot, we can see the continuation of the street below atop the parking garage. In this scene, cameras were mounted about 70' high above the streets below.ĭuring the afternoon on a clear day, we can see cars traveling ~30-40 MPH on the street, along with pedestrian traffic.Īt night, we can get a good view of cars moving through the scene, as well as see the flashing lights of a firetruck responding to a fire alarm in the building across the street. Ambient street light behind the cameras is also visible. In this scene cameras were aimed at a baseball field viewing spectators and the game itself.Īside from a few lights that illuminate the street leading from the baseball field, this scene is ~1-2 lux with clear skies and moonlight. The 5 MP camera would sometimes switch from black and white to color, depending on the amount of light in the scene. The wind was blowing steadily, and would pick up speed occasionally.ĭuring the early night, traffic was steady, and the wind began to calm down. Time of day was late afternoon, with steady amounts of traffic through the intersection. Time of day was early afternoon under mostly clear skies, and we can see cars and individuals walking through the parking lot.Īt night, scene lighting stays relatively bright, resulting in the cameras staying in color mode rather than switching to black and white.įor the intersection, we mounted cameras ~10' high, monitoring traffic moving ~15-30 MPH through the intersection, as well as pedestrian traffic. We had our test subject enter and exit the building as is typical.Īt night after a quick rain shower, fluorescent lights are on above the entrances to the office building.Ĭameras were mounted ~10' above the ground, looking out at a shopping center parking lot. This scene was shot on a clear, sunny day. In this scene, the cameras were located at the corner of an office building, about 10' high, viewing two entrances, one used by employees, the other by visitors. Set the right expectations about what quality / details / limitations the cameras have.Learn the key performance patterns across cameras and scenes.See for yourself the tradeoffs amongst cameras in applications / scenes you are using.Notice the significant difference in performance: This field is ~1-2 lux with the exception of the back area near the street lights.
Here's one of the 16 shots so you can get a feel of what they consist of / provide:

Then for each of these 16 shots, we prepared side by side comparisons plus video clips and full size image exports. Here's an overview of the day time shots: We tested entrances, fields, intersections, parking lots, parking ramps, vehicle exits, and city streets.

16 total shots - 6 cameras, side by side, from 720p to 10MP, were recorded at 8 different scenes.
