First things first, you need to know how many pixels (the resolution) is needed for home monitoring.
Basically, the HD security cameras, short for High Definition cameras, should be capable of identifying the license plate and human faces, so that it can capture the culprit with necessary details if anything happens.
In that case, 1080p HD security cameras or higher resolution HD IP cameras are what you are exactly looking for, according to the PPF (Pixel Per Foot) calculation, a widely acknowledged measurement for facial and plate identification. And 40 PPF is the baseline for proper recognition.
For example, you want to see an object that is 40 feet away clearly:
|PPF (=Horizontal Pixel/Distance)||40 Feet Distance of View||Can You See It Clearly|
You may also calculate the PPF of the HD security camera yourself by inputting the desired viewing distance into the above formula to check whether you can see things clearly that far away.
Obviously, the more PPF you get, the more details the HD security camera can offer.
And currently, in 2021, the most widely used HD IP cameras are among the resolution range of 2MP to 8MP as the higher HD CCTV is becoming more affordable these days.
So what's the HD security camera resolution really like? Here are several HD IP camera video samples in the real-world uses from users worldwide.

Important Note: The HD security camera video quality is NOT all about resolution. And that's why you will find some claimed super HD CCTV cameras still product horrible images. So choose a reputable brand is really important to promise not only high resolution but also true clear videos, with better lens and manufacturing.
Good HD security cameras are not only measured in pixels.
What makes a good HD surveillance camera? What kind of HD IP camera should you buy? There are a lot more to consider when buying an HD security camera or NVR kit, including night vision, WiFi, zoom, 3rd-party compatibility and more. Let's take a look.
1. HD CCTV Cameras with Night Vision
Many people asked in forums for "suggestions to purchase and set up a 1080p or 4MP crystal clear HD security cameras with strong night vision".
Nowadays most HD security cameras feature night vision function for round the clock monitoring, while there could be differences in their night vision image clarity and viewing distance in low light conditions.
Quality night vision HD security IP cameras feature infrared LEDs, capturing clear footage of night vision, even in 0 Lux no light conditions when human eyes fail to identify a thing.

2. Wireless HD Security Cameras
HD IP security cameras can be divided into 2 types: wired, and wireless, namely WiFi-enabled HD cameras.
Most wireless HD security camera reviews speak highly of this type, for its easy setup. People who don't have a lot of technical know-how will still be able to complete the installation without an issue.
And recently, with the emergence of the battery powered security cameras, the setup has become a real no-brainer! Just put in the batteries, it is ready to work and capture high definition videos instead of a fuzzy figure.
And this kind of wireless HD security cameras is usually small, helping to keep your camera concealed if you want it to remain covert. No wires, not as big, easier to hide if you want to keep it out of sight.
Editor's Note: The wire-free HD security cameras can do 1080p video recordings at best, currently, to provide you with enough details if anyone tries to invade your house.
3. A High Definition Security Camera with Zoom
If an HD security camera has adjustable zoom lens and focus, you can zoom in to see a closer view of far-away objects, and zoom out to get a wider view. Zoom can be divided into digital zoom and optical zoom.
Nowadays, HD surveillance cameras selling usually come with optical zoom, which will not damage the original video quality after zooming in. If your HD security camera system is 1080p, and has a 2X optical zoom lens, it still captures images with 1080p HD resolution when you magnify it 2 times bigger.
A more advanced type – HD PTZ IP camera with 4X optical zoom, not only allows zooming in and out, but also enables a 360° endless horizontal and 90° vertical rotation. Not a single detail will escape from the video monitoring.
Good news is that HD security cameras are highly affordable these days!
But don't be cheated by those dirt cheap HD IP cameras without real-world video samples. A good way to avoid being fooled is to check the videos from the users in Amazon store or the official online store video section to make sure you get what you wanted.
As for the HD security camera price, it will differ between different camera resolutions. The price range would be roughly like the following:
|2MP (1080p)||Around $50|
|4MP (1440p)||Around $50|
|5MP (1920p)||Around $65|
|4K (2160p)||Around $150|
|4MP HD security camera system||Around $400|
|5MP HD IP camera system with NVR||Around $450|
|4K/8MP HD IP camera system with NVR||Around $550|
Generally speaking, 5MP HD security camera is greatly sufficient for home and small business applications, and right now 4K is super expensive for decent quality stuff, as you may have noticed.
HD security camera system with an NVR/DVR is usually more expensive. The NVR lets you record the HD videos for viewing later. An HD security camera system with 4/8/16 channel NVR/DVR features more than just a single camera. 4/8/16 channel means 4/8/16 HD cameras at most can work with the network video recorder at the same time.
Here is a list of top-selling HD security cameras in 2021, covering a wide resolution range you may be looking for, with rich features at a highly affordable price.
