Building Traffic Safety Programs that Deliver Lasting Results

At Sitestream, the front end of a vehicle speed detection program typically begins with a purpose-built, radar-based camera for fixed installations and LiDAR-based portable cameras for handheld applications.  Radar and LiDAR are universally accepted by law enforcement and courts across the US for speed detection. The underlying science for both is widely recognized - and as such - speed measurements are considered valid evidence.

In a nutshell, when a vehicle passes through a Sitestream enforcement zone, the system:

• Detects the vehicle's speed

• Compares that speed to the posted speed limit and enforcement threshold

• Determines whether the vehicle meets the criteria for a potential violation

In a nutshell, when a vehicle passes through a Sitestream enforcement zone, the system:

• Detects the vehicle's speed 

• Compares that speed to the posted speed limit and enforcement threshold 

• Determines whether the vehicle meets the criteria for a potential violation

Once a vehicle exceeds the enforcement threshold, the system automatically captures evidence associated with that event, such as:

• Time and date of the violation

• Recorded vehicle speed

• Posted speed limit

• Lane information

• High-resolution images of the vehicle

• Video evidence when applicable

• Location information

The objective is to create a complete evidentiary record of the event.

Our speed enforcement systems capture only the information relevant to speed violations. We use rear-facing cameras, capture only violating vehicles and adhere strictly to authorized data handling and retention policies.

Once captured, the violation data is securely transmitted to our secure review environment.

Our backend processing software incorporates:

• Data integrity controls

• Audit trails

• Chain-of-custody records

• Secure data storage

These safeguards support both program transparency and legal defensibility.

A critical step in our violations acceptance process is human review. Our team of trained and vetted reviewers typically verify:

• Vehicle speed vs. enforcement threshold

• Vehicle make, model, color information

• Image quality

• Compliance with program rules and policies

• The evidence as it relates to enforcement action

This review process helps avoid errors and ensures that only valid violations are queued for police approval.

Once all requirements are satisfied, a citation is mailed to the vehicle owner for payment or contest options. 

Citations include:

• Date and time of violation

• Location of violation

• Vehicle speed

• Posted speed limit

• Registered owner details

• Registered vehicle details

• Photographic evidence

• Payment and adjudication instructions

• Information regarding appeal rights
