The UGREEN LP793 (35579) is a compact, portable infrared camera lens detector engineered to locate hidden pinhole cameras, mini spy cameras, camera pens, and lighter cameras in hotel rooms, rental properties, Airbnb accommodations, changing rooms, bathrooms, offices, and meeting rooms — anywhere unauthorised surveillance is a privacy concern. Weighing just 13 grams with a 5-metre detection radius, 4x infrared LED lamp beads, a double-layer HD crystal viewing mirror, a smart light-sensing chip, USB-C recharging, and 720-hour standby battery life — the LP793 is the essential travel privacy tool for business travellers, frequent hotel guests, and security-conscious individuals.
HOW IT WORKS — INFRARED LENS REFLECTION DETECTION
The LP793 uses optical infrared detection — a method that exploits the unique reflective properties of camera lenses. All camera lenses — regardless of how small, disguised, or hidden — reflect infrared light in a distinctive way when illuminated with an IR source. The LP793's 4x infrared LEDs emit a controlled IR beam; when the beam strikes a camera lens, the lens retro-reflects the infrared light back toward the viewer as a bright glowing spot visible through the LP793's red-filtered crystal viewing mirror. The human eye cannot see this reflection without the filter — the LP793 makes it immediately visible as a bright, unmistakable light point against a dark field.
This detection method works on all camera lens types regardless of brand, size, or disguise — pinhole cameras embedded in smoke detectors, alarm clocks, USB chargers, books, picture frames, ventilation grilles, or any other common household object can be detected using the LP793's infrared scanning method.
4x INFRARED LED LAMP BEADS — FOCUSED IR ILLUMINATION
Four infrared LED lamp beads focus on dangerous sight lines, providing a concentrated, even IR illumination pattern across the detection field. The four-LED configuration provides more complete coverage than single-LED alternatives — reducing shadowing and dead spots during scanning that could allow a camera to be missed. The 5-metre detection radius enables quick and easy scanning of an entire room with a large detection range without requiring close proximity to suspected concealment locations.
DOUBLE-LAYER HD CRYSTAL VIEWING MIRROR — CLEAR, AMPLIFIED DETECTION
The LP793's double-layer high-definition crystal viewing mirror serves as a precision optical filter that passes the specific wavelength of infrared light reflected by camera lenses while blocking the surrounding visible light that would otherwise wash out the detection image. Looking through the mirror while scanning creates a high-contrast red-field view where camera lens reflections appear as intense bright spots — immediately distinguishable from ordinary surface reflections and ambient light sources.
SMART LIGHT-SENSING CHIP — DISTINGUISHES CAMERAS FROM ORDINARY LIGHT SOURCES
The smart chip identifies peeping light sources, filtering ordinary reflective surfaces (mirrors, glass, metal) that would otherwise generate false positives. Without a smart chip, every reflective surface in a room triggers a detection response — making the scanner unusable in normal furnished environments. The LP793's intelligent chip reduces false positives by distinguishing the characteristic retroreflective signature of a camera lens from the diffuse or specular reflections of ordinary surfaces.
THREE LIGHTING MODES — OPTIMISED FOR DIFFERENT ENVIRONMENTS
Three lighting modes adapt to different indoor lighting conditions:
- Solid mode: continuous IR illumination for direct pinhole camera detection — optimal in dark or dim environments
- Slow-flash mode: pulsed IR illumination that highlights lens reflections and is suited to various indoor lighting conditions with ambient light present
- Off mode: LEDs disabled for standard use
Scanning is clearer after turning off the room lights, though the LP793 functions without turning off the light.
720-HOUR STANDBY + 60-MINUTE ACTIVE USE PER CHARGE
720 hours of ultra-long battery standby from the 60mAh internal battery — the LP793 is ready to use on demand throughout extended travel without requiring regular recharging. 60 minutes of active scanning use per full charge via USB-C — sufficient for a complete hotel room scan and additional scanning sessions between charges. USB-C charging shares a cable with smartphones and laptops for convenient travel charging.
13g ULTRA-LIGHTWEIGHT — KEYCHAIN PORTABLE
At just 13 grams and a compact PC+ABS body, the LP793 slips into any pocket, keychain loop, travel pouch, or laptop bag accessory compartment without any meaningful weight or bulk addition. The LP793 is designed to be carried at all times during travel — available for use whenever a new accommodation or private space requires checking.
