"feature": "180° Panoramic Surveillance in 4K 8MP Ultra-High Definition\nDual-lens camera design provides an immersive view of your outdoor areas, so you capture every detail with no blind spots. 4K 8-megapixel resolution battery security camera will snap crisp, un-pixelated shots of faces and license plates (even when zoomed in) in ways that 2K and 1080p systems can't!"
},
{
"feature": "Smart Detection: Reduce False Alerts\nAdvanced Person / Vehicle / Animal detection algorithm reduces false alerts - and only notifies you when it matters."
},
{
"feature": "Beyond Night Vision with ColorX\nColorX optics feature enlarged f/1.0 aperture and 1/1.8” sensor - resulting in 2X light intake and sensitivity. Unlike infrared night vision or spotlights, ColorX doesn’t cause reflection – so you can catch license plate numbers at night. ColorX also corrects for extreme light & shadows, and renders colors faithfully – so your nighttime footage looks like it was shot in mid-day!"
},
{
"feature": "Flexible and Safe Storage - No Monthly Fees\nSolar camera features an on-board microSD card slot (up to 512GB capacity) so you can record directly to the device. Access footage anytime from your Reolink app. Camera keeps recording, even when Wi-Fi is down! You can also record to a Reolink Home Hub or Wi-Fi NVR (sold separate). No subscriptions and no hidden fees."
},
{
"feature": "Two-way Audio Mic + Built-in Siren and Spotlight\nCommunicate with anyone as they approach your camera - listen to everything in view. Warn away intruders automatically when motion is detected with a booming Siren and bright Spotlight."
},
{
"feature": "Always-On Solar Power\nIncludes a 6W solar panel that can mount close to camera or away from the unit with the supplied 2.3-ft cable. Can also run solely on battery power for a limited time."
},
{
"feature": "Time Lapse\nWitness hours, days, even weeks of footage in fast-forward. See a construction project rise from the ground-up or watch breathtaking sunrises and sunsets - in one short, condensed video."
},
{
"feature": "Adapts to Your Wi-Fi Network\nUnique dual-band Wi-Fi connectivity keeps your wireless connection stable and reduces interference by working seamlessly with both 2.4 GHz and 5 GHz Wi-Fi bands."

Argus B740X’s dual-lens camera design produces a seamless panorama view of your entire yard, with zero blind spots. 4K ultra-high definition (8-megapixel) resolution means your footage is crisp and un-pixelated - even when zoomed in on faces or license plates! Person/Vehicle/Animal detection algorithms greatly reduce false alerts. Features ColorX optics that let you see nighttime scenes in bright, vivid colors, without the need for a glaring spotlight. During the day, ColorX will correct for extreme shadows and highlights, exposing hidden details you would normally miss. Mount camera and solar panel to outdoor walls, ceilings, eaves or even trees. Perfect for light-commercial and residential properties with reliable Wi-Fi.",
