The Portal Guardian dismantles this paradigm. It transforms your door into an intelligent access point with a 3.5-inch HD display, a 120-degree wide-angle lens, and real-time electronic viewing that turns every visitor into a clear, identifiable image before your hand touches the lock.\u003c\/p\u003e\n\u003cp\u003eDesigned for apartment dwellers, homeowners, and small business operators, the system captures what traditional peepholes miss: peripheral approach, package deliveries, and nighttime visitors. The integrated doorbell function and infrared night vision ensure that darkness is not a blind spot. Installation requires no wiring, no drilling, and no professional — it replaces your existing peephole in under three minutes, delivering enterprise-grade door surveillance at residential accessibility.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eBefore you open the door, know who stands behind it.

The Portal Guardian fills the security gap between a basic peephole (which distorts and records nothing) and a full smart doorbell system (which requires Wi-Fi, wiring, and monthly subscriptions). For seniors who want to screen visitors without approaching the door, for parents who want to know when children answer the doorbell, and for small retail back-offices that need discreet delivery-door monitoring, this device delivers enterprise-grade door surveillance at a single purchase price with zero recurring costs.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"product-faq\" style=\"max-width:800px;margin:30px auto 0;\"\u003e\n\u003ch3 style=\"color:#1A3A5C;font-size:20px;margin-bottom:15px;border-bottom:2px solid #1A3A5C;padding-bottom:8px;\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom:18px;padding:15px;background:#f9f9f9;border-radius:6px;\"\u003e\n\u003cp style=\"font-weight:700;color:#1A3A5C;margin-bottom:8px;\"\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Does this require Wi-Fi or an internet connection?\u003c\/p\u003e\n\u003cp style=\"color:#4a4a4a;line-height:1.7;\"\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. The Portal Guardian is a fully standalone device. All image processing, display rendering, and photo storage happen locally on the device. There is no companion app, no cloud subscription, and no dependency on your home Wi-Fi network. The only external requirement is 4×AA batteries, which last approximately 6 months under typical usage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:18px;padding:15px;background:#f9f9f9;border-radius:6px;\"\u003e\n\u003cp style=\"font-weight:700;color:#1A3A5C;margin-bottom:8px;\"\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Will it fit my door?

Metal doors within this thickness range work perfectly — the camera unit and interior display connect through the existing peephole hole using the included threaded cylinder. If your peephole aperture is outside the 14–28mm range, a simple drill-bit expansion is all that is needed. No wiring, no external mounting brackets, no permanent modifications to the door surface.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:18px;padding:15px;background:#f9f9f9;border-radius:6px;\"\u003e\n\u003cp style=\"font-weight:700;color:#1A3A5C;margin-bottom:8px;\"\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How clear is the night vision?

At typical doorway distances of 0.5–1.5 meters, the IR illuminator produces clear monochrome images with sufficient facial detail for identification. For best results, avoid pointing the outdoor unit directly at a bright streetlight, which can cause IR sensor saturation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:18px;padding:15px;background:#f9f9f9;border-radius:6px;\"\u003e\n\u003cp style=\"font-weight:700;color:#1A3A5C;margin-bottom:8px;\"\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Can multiple people in the household monitor the door?\u003c\/p\u003e\n\u003cp style=\"color:#4a4a4a;line-height:1.7;\"\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The indoor display unit is a single screen mounted on the interior side of your door. Anyone in the room with the display can view the live feed or browse captured photos. For multi-room monitoring, there is no wireless streaming capability — this is a focused, privacy-first device.
