Defender 4K Wired Security System impressions: First-class video, economy app

The 4K smart cam juggernaut is rapidly approaching. With the excellent Arlo Ultra blazing a trail earlier this year, prepare yourselves for a swarm of slinky new security cameras — packing ultra high-definition (UHD) image quality and other trinkets  — to hit the market in the coming months.

While you may expect these dazzling new devices to arrive with hefty price tags, the $450 Defender 4K Wired Security System proves that may not be the case. It’s a 4-camera system supported by a stand-alone 1 TB network video recorder (NVR), negating the need for ongoing cloud subscription fees. 

While it may not have all of the bells and whistles of pricier packages like Swann’s new 4K Security System, it promises to deliver a high standard of smart surveillance, with an 8.3 MP sensor delivering that 4K (3840 × 2160 resolution) goodness.

Complex, clunky cabling

Of course, a low price typically leads to compromise. Defender 4K cameras are compact and built for the elements, with an IP67 weatherproof rating, but they’re not particularly pretty and lack advanced features like the integrated PIR sensors you’ll find on premium competitors. The supporting plastic wall mounts feel cheap and only offer vertical adjustment, making camera positioning more difficult than it should be.

Cabling is also quite complex, with individual — and chunky — 12-volt DC power and BNC data connectors favored over a more convenient power over Ethernet design. All four cameras connect to a single power supply and directly to the NVR, so you’ll certainly need to think through your wiring design and power outlet availability ahead of installation. Considering Arlo Ultra’s wire-free design and easy installation, Defender 4K looks to be quite the dinosaur.

Pin-sharp 4K, narrow field of view

You’ll be delighted with Defender’s 4K images, which are crystal clear, with accurate colors and balanced contrast. Night vision delivers well-illuminated images with good range. Video quality and detail impresses, whether you’re monitoring the feeds on a small 4K monitor or big-screen TV. However, a horribly narrow field of view of just 79 degrees is well behind most modern smart cameras. In fact, it’s less than half of what the Arlo Ultra provides, so you’ll need to position your cameras carefully to cover your property’s entrance and exit points.

Dated mobile app

Like most modern NVR systems, you can choose to manage cameras and recordings directly using a supplied USB mouse or via an accompanying mobile app. We found Defender’s NVR software to be responsive. Accessing camera feeds and configuring recordings was easy enough, although if you’re new to multi-camera security apps, you’ll need to invest plenty of time getting up to speed with Defender’s advanced settings and technical terms.

We found connecting the supporting mobile app to be trickier than most security systems, requiring settings that need to be tweaked on both NVR and a smartphone, as well as a scan of a QR code on screen (which didn’t work) or a second QR code stuck onto the NVR hardware. The clunky setup experience provided a clear indication that Defender’s app — and overall user experience — lacks the friendly, intuitive design we expect from modern smart home devices. 

Monitoring our four cameras via the mobile app was reasonably straightforward, as was accessing previously captured recordings. But while we admire the jump to 4K resolution, Defender 4K feels outdated in others areas. It lacks both the seamless usability of modern smart home security systems and misses out on advanced features such as variable alert triggers, notification filters, person or facial recognition, and third-party device integrations.

Conclusion

A price tag of $450 is certainly attractive for a 4-camera UHD NVR system, but you’ll need to invest a significant amount of time installing, configuring, and, in some cases, battling Defender 4K’s old-school hardware, interface, and feature design to overcome its limitations.

A hand pressing the Nest Doorbell button.

In addition to the best home security cameras, you can keep your family safe by installing a video doorbell like the Google Nest Doorbell. If you don't have one yet, you're in luck because you can get the wired version of the device from Amazon's Woot for just $75, which is less than half its original price of $229. You'll need to hurry if you want to take advantage of the $154 in savings though -- while there's still several days before the offer expires, it's very much possible that stocks run out within the next 24 hours.

Why you should buy the Google Nest Doorbell
The battery version of the Google Nest Doorbell appears in our roundup of the best video doorbells, but if you already have wiring in place or if you prefer not to deal with recharging batteries, then you should go for the wired Google Nest Doorbell. The two versions are mostly the same aside from their power source, with features like 24/7 streaming that will let you look through the video doorbell's camera, alerts when it detects that someone is standing at your door, and the ability to talk with visitors and delivery people.

Why you should buy the Colgate Hum Electric Toothbrush
The Colgate Hum toothbrush, especially at this price, allows for an introductory tour of the world of smart toothbrush and app-driven dental care without taking one's wallet hostage. From a functionality perspective, the interesting thing about the Colgate Hum toothbrush is how it uses an app to track how you brush your teeth. It'll even give pointers, based on your brushing technique, about what parts of your mouth ought to be given more attention with its vibrating bristles. Though, as our Colgate Hum toothbrush review is quick to point out, the system isn't perfect — you can fool it by pretending to brush your teeth — and is obviously no substitute for regular dental visits.
