The most significant difference between Google's two Chromecast with Google TV options is resolution. While 2020's Chromecast with Google TV can output video in 4K at 60 frames per second, the new Chromecast with Google TV (HD) can only manage 1080p in up to 60 frames per second. So if you've got a 4K TV, you'll need to buy the older, $50 Chromecast with Google TV to take advantage of all those pixels. Meanwhile, TVs that top out at 1080p are a good match for the $30 Chromecast with Google TV (HD).
Storage space, a sore spot for many users of the original 4K Chromecast with Google TV, is also unchanged in the 1080p version. Both come with just 8GB, which can be limiting if you use a lot of different streaming services. Neither model has expandable storage built in, but either one will accept a compatible USB-C hub, so you can add additional storage using a USB-C hub if you need it.
Knowing the differences, it's pretty simple to figure out which Chromecast with Google TV is right for you. Assuming price isn't a consideration, the older 4K model should be your go-to if you intend to use it with a 4K display, as the HD model only goes up to 1080p. And if you happen to have a 1080p display that supports Dolby Vision, the 4K edition might also be better for you, as the 1080p model offers HDR10 and HDR10+, but not Dolby Vision.
If your screen is 1080p or lower and doesn't support Dolby Vision, the $50 Chromecast with Google TV won't have any advantages for you over the $30 HD model. So go for the Chromecast with Google TV (HD) if your TV or budget calls for it.
A 1080p camera provides a resolution roughly 2 times higher (1920×1080) than its 720p counterpart. It means it captures double the size a 720p camera does, which makes 1080p a great tool for surveilling medium-size areas like offices, shops, backyards, medium-size warehouses. You may need more cameras of this type if you want to get a large warehouse covered by your video surveillance system.
One more thing to know about 1080p cameras is that they provide a lower image quality when zoomed compared to 5MP (2592×1944) and 4K (3840×2160) cameras. The zoomed image of 5MP and 4K is clear and detailed, yet the 4k allows to see even more details given its deeper zoom. When it comes to resolution, 4K camera covers a 1.5 larger area than the 5MP one.
When it comes to the field of view, you might expect the 4K camera to reign supreme. You would be absolutely right. Given millions of pixels packed in one image and built-in wide-angle lenses (Megapixel security cameras are often packed with wide-angle lenses), 4K cameras provide a wider field of view. And while it is possible to reconfigure 5MP and 1080p cameras so that they cover wide areas, there is no point in it. The edges of the image will be obscure and you will fail to recognize any physical traits of people, number plates, and other small details.
ZOSI 1080p camera with better image quality and better resolution, and the price is equivalent to a 720P camera. Again, it becomes a good investment when aimed at surveilling a space that is compatible with its resolution. 4K Camera is the most expensive video surveillance option. However, it captures a large area which allows you to buy only a few cameras to record the whole parking lot, warehouse or supermarket.
Security camera with 1080p resolution is your go-to option if you have a limited budget and need small areas surveilled, such as driveways, front doors, farms, small shops, garages, boats, and motor homes.
Given their low resolution and blurred image, 720p cameras are not a recommended choice if you look for a reliable surveillance solution. You can buy instead of the best and cheap 1080p or 5MP security cameras for below $100 which is close on the price spectrum but provides a much better image quality.
On the whole, all four cameras differ in many ways. While the 720p camera comes at a lower price, it is a weak player in the video surveillance field. You are much better off choosing one of the remaining cameras. 5MP and 1080p cameras fit a medium budget and provide decent image quality and resolution that prove the surveillance system is not installed in vain. If you want, though, to get the best of the best on the market now, go for a 4K camera with 12-megapixel resolution, multifold digital zoom, and a wide field of view.
The 1080 and 720 in 1080p and 720p stand for vertical screen resolution, or height, in pixels. The more pixels there are in an image, the clearer it will be. As such, a screen resolution of 1920x1080 (two million pixels when multiplied) should appear twice as sharp as a resolution of 1280x720 (fewer than one million pixels). Meanwhile, the p in 1080p and 720p stands for progressive scanning, which updates full frame images more quickly than traditionally interlaced content.
HD DVDs contain 720p content and sometimes 1080p, while all Blu-ray discs contain 1080p content. Regular DVD quality can vary considerably, with some displaying content at a resolution lower than 720p, such as 480p. Moreover, there are still DVD players around that only carry support for up to 480p or 480i, meaning a viewer cannot get the full experience of any high-definition DVD they insert into the player.
Netflix typically streams at 720p, but with the release and expansion of what it calls "Super HD," users are able to stream more and more content at 1080p quality with a high-speed internet connection. Apple TV allows users to choose between 720p and 1080p streaming. DirecTV displays a "1080pHD" logo on 1080p pay-per-view content, and all their latest DirecTV Cinema content is in 1080p. On YouTube and Vimeo, high quality videos often allow for 720p or even 1080p streaming.
Modern smartphones, like the iPhone 5c/5s, the Samsung Galaxy S5, and the HTC One, tend to film at 1080p quality and at 30 frames per second, if not better. Again, resolution is not all there is to picture quality, but for the average user, modern smartphones' video recording capabilities have the potential to be just as good for casual video-making as cheap camcorders.
Screen resolution can be especially important in video gaming. Because there are more pixels in 1080p, less anti-aliasing is required for a smooth visual experience. This means that 1080p will not only likely look better than 720p, but will lead to a better gaming experience overall, as anti-aliasing can slow down a console or computer.

It means that if you need to monitor a large area with four 720p HD security cameras, only ONE single 4K CCTV security camera will get the job done, leaving no blind spots and no opportunity for potential thieves.
In the same H.264 video standard, there is no doubt that 4K ultra HD security cameras would require more bandwidth usage and storage consumption, compared with 1440p IP cameras, 1080p IP cameras and 720p IP cameras.
Important Note: Actually, some high quality 1080p Full HD security cameras might also offer you clear images with vivid details, just like the Reolink Argus 2E 1080p rechargeable battery security camera (shown as below).
Now that you have learned the differences among 4K security cameras, 1440p security cameras, 1080p security cameras and 720p security cameras, you can be off to choose the one that best meets your security needs and budget. 2b1af7f3a8
