- Can I connect external telemetry?
Yes. The camera includes an Ethernet port that supports external modems, including satellite modems. It also has a built-in 4G GSM modem.
- Can I use my own SIM card?
Yes. The QC4 is not shipped with a SIM card—users must provide one. The WebUI allows you to configure the APN for your SIM.
- What is the surface velocity measurement range?
Landscape 2mm lens: 80 m. Portrait 4mm lens: 120 m.
- How many cameras does QC4 have?
Two stereo cameras (four lenses total): one Landscape (2mm lens with IR filter) and one Portrait (4mm lens without IR filter).
- Do both stereo cameras record video?
Yes. Each stereo camera records video from both lenses. The system selects the best data source for processing, based on video quality and timing.
- What is the field of view of the cameras?
Landscape 2mm lens: 110°. Portrait 4mm lens: 80°.
- What is the stereophotogrammetry measurement range?
Landscape: 20 m. Portrait: 35 m.
- Is there a cost for AWS data storage and processing?
Yes, there is a monthly fee.
- What type of batteries are used?
Enepower BCB-786269. One battery in the camera and three in the battery box.
- Can QC4 integrate with third-party cloud services like GovCloud?
No. QC4 currently operates only on AWS.
- Can discharge data be exported to external services (e.g., Hydstra)?
Yes. Data can be exported via API to external platforms or websites.
- How much data is stored in the cloud and for how long?
Up to 12 months per site. You’ll be notified when nearing the limit and given a 3-month grace period to download data. API automation is available.
- What are the software requirements?
The WebUI and cloud interface run on any modern web browser and device.
- Does the cross-section survey require XYZ format?
QC4 accepts XYZ formats
- Will users see “Raw-external” and “Learning-external” discharge data?
Yes, both are visible and exportable.
- How accurate must the external water level sensor be?
Recommended accuracy is ±0.1% FS for best results.
- Can QC4 process flow if external water level is delayed?
Yes. QC4 records video independently and will process flow once updated water level data is received via API.
- What is battery life (camera + battery box) without solar charge?
Approx. 5 days with 1-hour daily IR-light scheduling. Actual performance varies by conditions.
- What is battery life (camera only) without solar charge?
Approx. 1 day under similar conditions. Not an official figure.
- What is overall battery life expectancy?
Under ideal conditions, 5–10 years.
- If one battery fails, will QC4 still operate?
Yes, the system remains operational.
- Do batteries need to be replaced at a service center?
Yes. Battery replacement must be done at an authorized center for warranty and sealing integrity.
- Can QC4 use two external water level inputs at once?
No. Only one sensor input is supported at a time.
- Can I use multiple water level sensors via API?
Yes. Redundant sources can be managed via API, but only one will be active at a time.
- Can I use my own external lighting?
Yes, if it’s within output limits (unofficially 12V DC, 3A Max, 36W).
- Can I use a high-power light?
Yes, but an external power source is required. The camera’s IR output can trigger the light.
- Can point cloud data help with camera setup and cross-section accuracy?
Yes. This capability is in development.
- Will QC4 ship directly to customers?
No. QC4 ships to RIC/service centers, which then distribute to customers.
- Does QC4 provide a rating curve equation?
No. It currently provides only a stage-discharge table.
- Can QC4 measure at night?
Yes. The system uses IR or white light. Accuracy depends on light type, brightness, and surface conditions. Lighting is managed by the camera.
- What water level sensor comes with QC4?
The MJK 1400 sensor with 7070D connector. It supports plug-and-play connection, 4–20mA communication, and WebUI configuration.
- Can I use my own 4–20mA level sensor?
Yes. Users can configure third-party 4–20mA sensors via the WebUI and connect using the supplied termination kit.
