Questions
- How accurate is the on-device recognition?
- Mode A (ESP-WHO on the ESP32 itself) enrols about seven faces and needs even frontal lighting; under side lighting our bench measurements fall well below what a panel expects. Mode B posts the frame to a Flask service running dlib and does far better with unlimited enrolments. Both are shipped, and the report measures and compares both rather than claiming a number we have not tested.
- Why is a separate base board included?
- Programming an ESP32-CAM without the CH340 base board means jumper-wiring an FTDI adapter and holding GPIO0 low by hand on every upload. The board costs us ₹120 and removes the single most common source of support calls.
- Does the report come with it?
- Yes. Every kit ships with the editable report (.docx and .pdf), a 20-slide PPT, circuit and block diagrams, commented source with pinned library versions, 25 viva questions with answers, and a printed wiring sheet in the box.
- Can I change the topic or add a feature?
- Tell us on WhatsApp before you order. Small firmware changes are usually fine; a different sensor means a different kit and a different price.
- Is there cash on delivery?
- No. Prepaid only — UPI, card or netbanking. It keeps the price where it is.
- Will the report match my college format?
- The .docx is unlocked and editable, so you add your college name, roll number and guide. The chapter skeleton follows the standard Anna University / AICTE structure.
