Despite all the great smart security cameras on the market right now, floodlight cameras are still the best option if you want a healthy dose of intruder deterrence and bright lighting alongside your video surveillance to eliminate dark hiding spots around your property. While they’re generally a bit pricier than regular security cams, the Blink Wired Floodlight Camera is currently 70% off, down to a record-low price of $29.99 (originally $99.99) for Prime Day.

This dual-LED wired model has 1080p video, color night vision, intelligent motion alerts, and a built-in siren. It’s compatible with third-party devices via IFTTT and Alexa voice controls, and is weather-resistant, though an IP rating isn’t stated. Along with a camera, the Blink Wired Floodlight features two LED floodlights with a combined brightness of 2,600 lumens (1,300 lumens each) with a 5,000K color temperature. This PCMag review, which gives it an "excellent" rating, notes that it's significantly brighter than the Blink Floodlight Mount, which doesn’t include a camera.

Both the lights and camera connect to the included fixture with mounting arms that give users a solid range of tilt and swivel adjustability, and a 143-degree field of view to minimize blind spots and capture broad areas. Users can view up to five minutes of live video at a time and receive motion notifications for free. To unlock more features, a paid subscription is required, and a hub (sold separately) is required for local video storage.  

Like other Blink devices, the camera can be controlled through the Blink mobile app, allowing you to livestream footage, take snapshots, and arm or disarm the system remotely. When armed, the camera automatically records video and sends alerts when motion is detected. At just $29.99, the Blink Wired Floodlight Camera is one of the cheapest ways to add bright floodlighting, video surveillance, and a built-in siren to your home's security setup.
