Dahua IPC-MFW7849Y-Z4-T8A 8+8MP Dual-Sight Polarlight Bullet WizMind Network Camera – 20‑80mm Zoom + 180° Panoramic
Triple‑Lens, Dual‑Channel – Ultimate 180° Panoramic with Extreme Detail
- Premium 1/1.2" CMOS Sensor (Channel 1): 8MP (3840×2160) with ultra‑low 0.0003 lux color illumination for exceptional low‑light performance.
- Powerful 20–80 mm F1.1 Telephoto Zoom: Motorized P‑Iris lens with massive F1.1 aperture – detection range up to 1,048 m (3,439 ft).
- 180° Panoramic Channel (Dual 3.6 mm F1.0 Lenses): Two 1/1.8" CMOS sensors with fixed F1.0 lenses deliver seamless 180° horizontal FOV at 8MP (4976×1452).
- Dual Micro‑PTZ & Independent Area Lighting: Remotely adjust lens angles for both channels; control warm light zones independently (8 LEDs on detail, 4 on panoramic).
- Simultaneous AI on Both Channels: Unlike other dual‑sight models, CH1 and CH2 AI functions can be enabled at the same time for comprehensive intelligence.
- Polarlight & Time‑Division Exposure: Extreme low‑light sensitivity (0.0003 lux) plus time‑division exposure ensures clear capture of people, vehicles, and non‑motor vehicles moving at different speeds.
- All‑Weather Rugged Design: Glass heater for defogging, IP67 weatherproof, wide operating temperature -40°C to +60°C (–40°F to +140°F).

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.

Love these.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I have them in black and white. I use them everyday in all shoes. These are very versatile and a great quality material. They take a looong time to wear and they stay in place. Very washable and good material. They are not too thick and they do not shrink. I do air dry mine. They do not hold smells even in the summer heat.

The perfect sock!
Size: 6-10, Color: Halo Gray/Assorted
The only socks that I can wear with my hey dudes. They stay on my ankles and never slid down into the shoe. I will forever order these as long as they are available. They are comfy too!
