Expectations
Single Vehicle Entry/Exit ๐ป
To ensure optimal Gate Report system performance, it is essential that only one vehicle enters or exits the gate at a time.
The system is designed to process and accurately identify individual vehicles. Multiple vehicles within the camera's field of view simultaneously may result in inaccurate or missed data points.
The client is responsible for maintaining traffic flow to ensure that the Gate Report system can capture clear images of each vehicle independently.
False Positives โ
The system might mistakenly identify something other than a license plate as a license plate. This can happen if there's an advertisement, a person wearing a numbered shirt, or any other object that resembles a license plate within the camera's view. This can lead to missed vehicle entries or inaccurate data.
It's important to understand that we cannot guarantee 100% accurate results in all situations. Factors like multiple vehicles, obstructions, and objects that mimic license plates can impact the system's performance.
The client is responsible for maintaining a clear view for the camera.
The ANPR camera shall be free of stationary vehicles parked in front of the camera, signs containing text or numbers that could be triggered by the Gate Report system.
If false positive event volumes exceed normal patterns we may consider your site a breach of the Gate Report fair usage policy and suspend the processing of events.
Client-Provided Data ๐
To accurately assess the Gate Report system's performance, Evercam requires clients to choose one of the following options:
Provide Manual Logs: The client will provide manual logs or manifests of all vehicles entering and exiting the site for the first two weeks after installation. This data will be used to verify the accuracy of the Gate Report system.
Report Individual Errors: If the client chooses not to provide Manual Logs, they will be solely responsible for identifying and reporting any missed vehicle events within the Gate Report system. Without a benchmark like Manual Logs, neither Evercam nor the client can independently verify the systemโs overall accuracy. Therefore, Evercam will rely exclusively on client-reported incidents to assess system performance.
Calibration Period
A 14-day initial setup period is necessary for thorough system calibration and data refinement. During this time, client-provided data is crucial for identifying and correcting discrepancies.
Duplicate Entries and Other Reporting Considerations ๐
Our ANPR system may generate duplicate license plate entries within the reports. This is often due to vehicles stopping or parking within the camera's view, causing multiple captures of the same license plate. Additionally, trucks with two license plates can sometimes lead to incorrect plate cropping and duplicate entries.
It's important to note that our system requires a 48-hour verification period to ensure the accuracy of the data. During this time, our system will analyze the captured data to identify and correct errors.
To guarantee optimal system performance, we recommend a 14-day initial setup period to allow for thorough system calibration and data refinement.
While we strive for accuracy, it's essential to understand that these factors can influence the data produced by the ANPR system.
If duplicate event volumes exceed normal patterns we may consider your site a breach of the Gate Report fair usage policy and suspend the processing of events.
Please note: Duplicate entries and other reporting nuances should not be considered system errors but rather expected outcomes in certain conditions.
Visible Plate
Vehicles without a license plate will not be logged. This includes vehicles with badly damaged, dirty, or non-visible license plates.
Proper Registration Plate Mounting ๐ช
For accurate ANPR detection and reliable Gate Report logging, all vehicles must have registration plates that are securely and correctly mounted. This includes:
Plates must be mounted horizontally โ text should be upright and readable left to right.
Plates should be installed in their standard position (centred on the front or rear of the vehicle).
Plates must be fully visible and not rotated, obstructed, or relocated in a way that deviates from standard road compliance.
Improperly mounted plates (e.g. turned 90 degrees, positioned at extreme angles, or placed in unconventional areas) may fail to trigger a Gate Report event.
Obstructions ๐ง
Obstructions (people, machinery, etc.) that interfere with the cameraโs field of view may result in missed events.
Non-Evercam Gates
Entries/Exits through gates not covered by Evercam Gate Report will not be logged. If vehicles begin to use out-of-service gates, inaccurate results are expected.
Power Supply ๐
Loss of power to the Gate Report camera system will result in unlogged events.
Install Conditions
If the installation site conditions differ from the agreed-upon plan, including issues with the location or installation process, Evercam reserves the right to postpone installation. In this case, we will work with you to create a revised plan. A refund, minus site visit costs, will be issued.
Traffic Flow Compliance
Our ANPR camera system is designed to optimally capture license plate information when vehicles approach the gate in a straight line, perpendicular to the camera's view. Any significant deviation from this path, such as vehicles entering or exiting at an angle greater than 30 degrees, may result in missed license plate captures and inaccurate reporting. To ensure accurate data collection, it is essential to maintain a consistent traffic flow pattern as outlined in the Gate Plan.
Deviations from the specified traffic flow can lead to reduced system performance and potential inaccuracies in the generated reports.
Weather Conditions ๐ฆ๏ธ
Weather (rain, snow, fog) can reduce image clarity and result in unlogged events.
Speed Conditions
Vehicles going over the specified speed in the Gate Report Specification plan can result in unlogged events (50km/h).
Context Field of View ๐ญ
The context camera's primary and sole priority will be to capture the vehicle and only the vehicle while overlapping the field of view of the ANPR camera. It is not to be prioritised for any other purpose or product (time-lapse, BIM, site visibility, etc.) without first prioritising the Gate Report product.
