Defender NS8B4PTZ-1T AI Powered Sentinel 4K Wired Security Camera System: 360° PTZ with AI tracking
Meet the Defender AI Powered Sentinel 4K Wired Security Camera System – your new, overachieving security guard that never sleeps. With its 360° surveillance and AI auto-tracking, it’s like having eyes in the back of your head (literally). Got a thing for smart tech? You’ll love the smart human detection that sends real-time alerts straight to your phone, plus two-way audio so you can tell the pizza guy where to leave the box. And hey, the blue-red flashing light isn’t just for show – it’s like a disco for burglars, but they’re not invited. Thanks to 4K CLEARVU tech, you’ll get footage so crisp, you can count the leaves on your neighbor’s tree. And when the sun clocks out? No problem. Vibrant color night vision keeps things clear up to 100ft, even when it’s darker than your morning coffee. Plus, it’s weather-rated and uses Power over Ethernet, because who has time for complicated setups?
Why you’ll want this:
- 4x 4K UHD cameras mean no blind spots – unless you count the one behind your fridge.
- AI that’s smart enough to spot humans (and ignore your cat’s midnight adventures).
- Lights and a siren that say ‘move along’ to unwelcome visitors.
- 4K resolution with WDR makes everything look like a movie – except it’s your backyard.
- See in color at night, because black and white is so last century.
