Integrated 12V Boost Power
An onboard boost circuit supplies clean 12V power from the included 3.7V PPE LiPo battery. SDR v2 eliminates external adapters, unstable step-ups, and field improvisation.
Battery Powered and Rechargeable
Includes a PPE 3.7V 1800mAh LiPo cell that provides more than four hours of continuous runtime. PPE batteries use unique polarity and must be used with SDR v2. Recharge using the PPE 2-in-1 Fast USB-C LiPo Charger (sold separately).
Stealth Mode Switch
A hardware toggle disables WiFi for silent operations, NAC evasion, and reduced RF exposure. Ideal for sensitive environments and low-profile placement.
Discreet Mounting System
A magnetic rear plate and adhesive hook-and-pile strips allow quick mounting near doors, cabinets, badge points, and choke areas. No tripod, long standoff, or visible setup required.
