EVOCAM HALO Controller

Screen layout

Top toolbar, control panel (tabs) on the left, live video in the center and the captured image list on the right. From connecting the device to imaging, measuring and reporting, everything happens in one window.

• HALO Port / Cap Connect — connect the HALO device (COM port) and the camera
• Capture · Save + Overlay — capture the current frame, or save it with the measurement overlay
• DATE — stamps the capture date and time in the top-right corner of saved images
• Left tabs — Zoom · Focus · Exposure · Light · Save · Measure · Annotate · Report
• Click a thumbnail in the captured list to open it at full resolution

Lens · zoom

In the Zoom tab, set the lens and the camera zoom ratio, and jump to frequently used magnifications with the Quick Zoom buttons.

• Select the lens, then enter and apply the camera zoom ratio
• Quick Zoom buttons move to a preset magnification instantly
• The live image shows the current magnification and focus / exposure status in the top-left corner

Focus · Focus Stacking

Switch between auto (AF) and manual (MF) focus. For samples with height differences, Focus Stacking merges several focus levels into one image that is sharp all over.

• Auto / Manual focus
• Focus Stacking — merging several focus levels

Exposure · lighting

Adjust brightness and lighting for the sample in the Exposure and Light tabs. Camera mode, mirror / flip, noise reduction and color gain are changed in Image Settings.

• Exposure settings, lighting brightness and direction
• Image Settings — camera mode, Mirror / Flip, noise reduction, color gain

Saving and loading presets

Save frequently used viewing conditions to Preset 1–3 and recall them with one button, so you do not have to set them up again for every part in repetitive inspection.

Measurement — length · angle · circle

In the Measure tab, measure length, angle and circles with two clicks. Results collect in the measurement list below, and Save + Overlay saves the image with the measurement lines.

• Distance · Angle · Circle and other measurement tools
• Calibrated zoom buttons jump straight to a calibrated magnification
• Line color and width, decimal places and unit are set in Settings › Measurement

Edge-detection measurement

The software finds the edge automatically, reducing errors caused by where you click. It quickly measures the diameter and position of features with clear edges, such as round holes.

Annotate

Mark defect locations or add notes with text, shapes and arrows in the Annotate tab. Click with Select and drag to move them.

• Color, line width, font size and double-headed arrows are set in Settings › Annotation

Inspection reports (Report)

Choose the mode that suits your workflow. Recipe mode repeats "scan barcode, capture image, add row" and exports the session to one Excel file; Excel Template mode inserts values and images into the selected cell of a template that is already open.

• Define the columns (date, barcode, input, defect type, image, etc.) in the Recipe Editor
• Start Session → scan, then Enter or Add Row → Export…
• Scan button — reads the QR code / barcode / Data Matrix (including dot-peen marks) in the live image
• Excel Template mode requires Microsoft Excel on the PC

Save settings · backup

In Settings › Save, choose the save folder, whether every Capture is saved automatically, and the file format (PNG lossless / JPEG smaller files). Calibrations, settings and report recipes can be backed up to one zip file and restored.

• Calibrations › Backup All Settings… / Restore Settings…
• The state just before a restore is kept automatically, so it can be undone
• Calibrations belong to a specific device and lens; restoring them onto another device may give values that do not fit
