Ring's $249 (£195, AU$330 converted) Floodlight Cam is a definite improvement over your typical outdoor security light. In addition to being equipped with two LEDs, this Wi-Fi device also comes with an integrated 1080p HD security camera. Sign up for motion alerts in the related Ring app, where you can also set activity zones, create schedules and control the built-in 110-decibel siren. Starting at $3 per month, you can view saved video history on a contract-free basis.

Rainbow, aren’t they beautiful? Have you ever wondered how a rainbow is created? It is a simple physical phenomenon called dispersion of light. So, what is the dispersion of light?

There's clearly a lot of functionality packed into this thing, but I can't give it full marks for the following reasons:

Netgear's Arlo was one of the first products to popularize modern, DIY outdoor home security. Since then, plenty of other manufacturers have followed suit with related devices like the Nest Cam Outdoor and the Canary Flex. Weatherproof security cameras integrated into outdoor lighting is one subcategory that has developed slowly, but is now becoming an industry trend.

This an extremely bright, 5W light that shines exactly at 365 nm. Great for the following: Carpets, Inspections of bathrooms, Cat urine, UV Curing, Clean room ...

When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion. The simplest way to explain dispersion is through dispersion in the prism.

During testing, the area around the Floodlight Cam typically averaged 10 mbps for download speed and 1 mbps (or slightly less) for upload speed. The Ring app says anything above 1 mbps for download and upload is good, but this Ring support page says at least 2 mbps is best. Because of this, we experienced some lag times, pixelated video feeds and a two-way talk intercom that occasionally cut in and out.

An infrared light absorbing layer is used to reduce cross-talk in an imager by absorbing the infrared light that leaks from the neighboring pixels.

Splitting of white light into seven constituent colours when passed through the prism. Prism is an optical element which is transparent with flat, polished surfaces that refract light. Change in the direction of propagation of light when passed through a different medium is called refraction of light.

Now you're ready to opt-in to motion alerts, create activity zones and more. One important thing to note is that you have to create activity zones before you receive any motion alerts, even if you've already enabled motion alerts. Once I figured that out, everything worked well. I received prompt alerts tied to motion outside. You can adjust the sensitivity of the sensor, too, if you're getting too many notifications of your neighbor's cat.

Ring's Floodlight Cam costs more than Kuna and Toucan, but less than Netatmo's Welcome. At the same time, the Floodlight Cam has 1080p HD video resolution compared to Kuna and Toucan's 720p HD. The Floodlight Cam's $3 per month cloud storage fee is also less than Kuna and Toucan's. The Welcome camera, on the other hand, has internal local storage so you don't have to worry about a monthly expense at all.

Actually, light does disperse into its spectrum of colours in a glass slab as well. We can see this if we observe it in a particular way. Before we proceed you should know something about refractive indices. They aren’t constant. They vary with the frequency of light and hence the wavelength.

When light travels from one medium to another, the speed of its propagation changes, as a result, it ‘bends’ or is ‘refracted’. Now when light passes through a prism, it is refracted towards the base of the triangle. The refraction of light through the prism is well illustrated in the diagram given above.

The live feed was clear in day and night mode and it was easy to set motion and lighting schedules in the app. The main limitation of this device will likely be your Wi-Fi connection. Out here in the Kentucky countryside, the Wi-Fi is hit-and-miss.

Ring's Floodlight Cam is a fairly simple DIY installation, but it's a hardwired device. If you have any reservations about setting up a product that requires electrical wiring, hire someone to handle it for you. I enlisted one of CNET's technical gurus, Steve Conaway, to install the Floodlight Cam.

Newton was the first to conduct this experiment on passing light through a prism. He let sunlight pass through the prism expecting to see the white light on the screen placed at the other side but instead, he saw the spectrum of light after dispersion. He had a small hunch regarding the significance here but decided to do something else here to confirm it.

It took Steve about 30 minutes from start to finish, but we ran into an unexpected setback along the way. The width of the Floodlight Cam's baseplate didn't match up with the width of the standard-sized electrical box at the CNET Smart Home. So, we currently have just one screw holding up the whole thing. That workaround has worked surprisingly well for us during testing, but it wouldn't be ideal for a more long-term installation.

The Ring Floodlight Cam tacks on some additional features like activity zones and night vision (which Kuna and Toucan don't offer). Ring also promises to add Floodlight Cam support for IFTTT, Samsung SmartThings, Wink and even Apple HomeKit soon. (A Ring representative told me Floodlight Cam's are already outfitted with the Apple MFi chips needed for HomeKit, it's just a matter of activating them.)

The Floodlight Cam comes equipped with two 1,500-lumen LEDs, which are each roughly equivalent to a 100W incandescent bulb. That isn't incredibly bright, particularly if you install it high on your roofline like a typical floodlight. Of course, you can also install it lower so it doubles as a porch light.

While these limitations make Ring's clever floodlight-security camera hybrid slightly less recommendable, it's still well worth your consideration.

Ring's $249 Floodlight Cam goes a long way toward helping you keep an eye on the perimeter of your home. At the same time, I really wish it offered free cloud storage as an entry-level option. I also wish Ring had introduced smart home integrations at launch rather than making us wait. Even so, you should consider adding Ring's LED floodlight and HD camera to your outdoor security setup. It's only going to get smarter with time.
