Cameras are an important part of NoPileups. Selecting the right cameras for your tunnel helps NoPileups prevent collisions more effectively.
Your in-tunnel cameras must meet these requirements to work with NoPileups:
- IP-based - NoPileups uses IP-based cameras
- Waterproof (IP66 or better) IP66 cameras are rated against high pressure spray from 360 degrees and have ingress protection for dust-sized particles
- Support MJPEG/H.264 compression - H.265 compression is not officially compatible with NoPileups, and should not be used
- WDR (Wide Dynamic Range) - WDR during video compression can make video alterations for lighting changes
- Have a main and sub stream (3 total streams preferred) - Sub stream uses smaller image sizes (768x480) to stream video using an RTSP link
- Support HD resolutions
- Support at least 12 frames per second - Framerates above 12 can create excess network latency, while framerates below 12 can cause NoPileups to not work as well
- Support RTSP (Real Time Streaming Protocol)
- Minimum 100 Megabit connectivity - If the camera uses more, ensure the network can handle the excess load
- Camera field of view between 90 and 110 degrees - Gauge the distance from the camera to the rail and use a millimeter lens that provides a good shot of the vehicle. Smaller cars are harder to detect for tracking. Using digital “zoom” means we have a less quality image
Cameras that use 360-degree views will not work with NoPileups.
If you need to add cameras to your tunnel, there are a few things to consider beyond the minimum requirements.
The cameras you select will need to be cleaned regularly. Choose models capable of repeated, thorough cleaning.
Waterproof cameras are a must, but also consider the water-resistance of the mounting hardware. The more resistant your cameras are, the less work you'll need to do over time.
Cameras with varifocal lenses are not required but allow for fine-tuning.
Dome-style cameras are highly recommended for use with NoPileups, as their housings are less prone to water damage and easier to clean. In addition, because of their shape, dome-style cameras are less likely to move due to various tunnel conditions.
Here is a short list of manufacturers whose cameras work exceptionally well with NoPileups:
- Digital Watchdog
Recommended PoE Gigabit Switches
NoPileups requires a gigabit connection between the camera switch and the NoPileups Server. The system also requires that all ports on the switch be PoE (Power over Ethernet). Here are our recommendations for gigabit switches with PoE:
- Buffalo 8-Port PoE Gigabit Switch
- Buffalo 16-Port PoE Gigabit Switch
- D-Link 8-Port PoE Gigabit Switch
- D-Link 24-Port PoE Gigabit Switch
