Home security cameras usually come with a tradeoff. You either run wires through your walls or climb a ladder every few weeks to recharge a battery. The TP-Link Tapo SolarCam C402 Kit skips both. It’s currently $39.98 on Amazon, down from its usual $59.99, and price trackers confirm this is its lowest tracked price to date.

Setup is straightforward: Mount the camera, position the panel where it gets steady sun, and let it handle the rest. TP-Link says around 45 minutes of direct sunlight per day is enough to keep the battery charged, and with an IP65 rating, the housing is designed to handle rain and dust. That makes it a budget-friendly option for a backyard, driveway, or shed where running power lines would be inconvenient.

Video tops out at 1080p and is not ultra-smooth, but it is detailed enough to identify someone approaching your door, and its 125-degree field of view captures a broad stretch of yard without the heavy curve you get from some wide-angle lenses. At night, you can switch between standard infrared for black-and-white video or use the built-in spotlight to capture color footage. The color mode looks better when there’s at least some nearby lighting, like a porch light or streetlamp, notes this PCMag review. There is also two-way audio for speaking to visitors and a built-in siren if you want an audible alert.

For storage, you can insert a microSD card up to 512GB, sold separately, or opt for Tapo’s cloud plan at $3.49 per month after a 30-day trial, which adds 30 days of video history and smart clip organization. On the plus side, it supports person, pet, and vehicle detection even without a paid subscription (which is not always the case with budget cameras). It also supports Amazon Alexa, Google Assistant, and IFTTT, though Apple HomeKit is not included. The main compromise is the 15fps video and the fact that you are relying on sunlight, so placement matters. For $40, though, this is one of the simpler ways to add a wire-free outdoor camera that does not demand constant maintenance.
