Overview

VistaZ image

VistaZ is designed for fully autonomous operation in retail environments where external power is unavailable or undesirable. It combines a rechargeable battery with ambient light energy harvesting to enable long-term, maintenance-minimized deployments.

When to Choose VistaZ​

VistaZ is recommended when:

  • External power is not accessible
  • Long-term autonomy is preferred
  • Coolers or freezers operate under consistent indoor lighting

Power & Battery Architecture​

  • Rechargeable 18650 Li-ion battery
  • Ambient indoor light energy harvesting
  • Battery continuously recharges under normal store lighting
  • No external power cables or connectors

Battery Performance & Lifecycle​

Battery performance depends on:

  • Cellular connectivity quality
  • Number of images captured per day
  • Door opening frequency
  • Ambient light availability

General Assumptions​

  • Typical usage: 1 image + 1 ping per day
  • Approx. 20 door openings/day
  • 12+ hours of indoor lighting

Key Notes​

  • Complete discharge does not indicate end of battery life
  • Repeated deep discharge shortens usable lifespan
  • LTE Cat-M1 with good signal can support higher image frequency

Off-Season & Low-Light Behavior​

  • If device is placed into sleep mode before prolonged darkness:
    • Recharge occurs within 3–5 days once light is restored
  • If not placed into sleep mode:
    • Recharge may take up to 30 days after extended darkness

Battery Replacement​

  • Battery replacement is required after several years of operation
  • Replacement must be performed by authorized personnel
  • Process is simple and fast when performed correctly

Handling Guidelines​

  • Do not puncture, drop, or immerse the battery
  • Do not puncture solar panels
  • Follow shipment and disposal regulations for Li-ion batteries
