2K Security Camera: Protect Your Home Safety
Many people, especially beginners, get confused by the terms and jargon used for security cameras. They might wonder what "2K" stands for and what it means in a 2K security camera.
In this article, we will explain what a 2K security camera is, its types, usage, and everything else you need to know before making a decision.
Let's start with the basics.
Part 1. What is a 2K Security Camera?
The word "2K" represents the resolution of the security camera. It means 2560 pixels in each row and 1440 pixels in each column. So, its resolution is 2560 x 1440 pixels, which is also known as 1440p and QHD (Quad High Definition).
With that being said, any security camera offering the said resolution is called a 2K security camera. It has a 4-megapixel (MP) image sensor for high-quality video. It is widely used and a perfect option for surveillance and ensuring indoor/outdoor security.
Part 2. Types of 2K Security Cameras
2K Wireless Security Camera
A 2K wireless security camera does not require a wire for power and network. It has built-in rechargeable batteries that power it and is usually connected to a small solar panel to charge itself. Therefore, it is suitable for outdoor places where the solar panel can receive radiation from the sun. But you can also use it indoors.
For network connection, there are two options. Some cameras can be connected to a Wi-Fi network and transfer data through a router. In comparison, some cameras can work on 3G/4G LTE. They require a nano SIM card with a data plan.
2K Wired Security Camera
Wired cameras can be divided into two types: DC-powered and PoE.
A DC-powered camera is powered through an adapter, which is connected to the nearby outlet. So, you can place it anywhere, and they do not require a wire for the network. Instead, they use Wi-Fi to transfer data through a router. It can be used for indoor as well as outdoor security.
A Power over Ethernet (PoE) uses an ethernet cable for data transfer and power. The cable is connected to an NVR or PoE router. It is a more reliable option for outdoor surveillance.
2K Security Camera System
A 2K security camera system is a complete set of multiple 2K cameras, a central control or NVR, and a transfer medium, which could be Wi-Fi or ethernet cable. If you want to cover your complete outdoor/indoor area, you need to use a camera system. All cameras are connected to one NVR and are controlled from a central point.
Part 3. When to Use a 2k Security Camera?
A 2K camera is a great fit for a wide range of purposes. It offers high-quality visuals within a modest budget, which makes it a good option for many people.
It gives clear and crisp videos of the individuals, pets, and vehicles in the covered area. You can ensure security and surveillance 24/7, whether it be your home or business.
Here are a few uses of a 2K security camera:
- Home entrances, including the main door and back doors.
- Baby, children, and pet monitoring
- Garage
- Driveways
- Backyard
- Small businesses
Comparison: 2K vs 4K Security Camera
The main difference between a 2K security camera and a 4K security camera is the resolution. A 2K security camera has a resolution of 2560 x 1440 pixels. It has a 4-megapixel (MP) image sensor. In contrast, a 4K camera has a resolution of 3840 x 2160 pixels. It is an 8-megapixel (MP) camera, which is much more powerful.
Therefore, a 2K camera has decent quality and image details. In contrast, a 4K is much clearer and more detailed; it can even read number plates and logos on objects. Even at night, they offer brighter and clearer images.
A 2K camera is definitely a decent option to save money. It also requires much less storage space for recordings and bandwidth for data transfer. It is widely compatible with devices and components of the security system. On the other hand, a 4K camera is much more expensive and requires two times more storage and 4-5 times better bandwidth.
