A 3MP wireless security camera system typically consists of several 3MP cameras wirelessly connected to a central recording device or network video recorder (NVR). The cameras are capable of capturing high-quality footage at a resolution of 2048×1536 pixels, making it easier to identify faces and other details in footage.
Wireless cameras are convenient because they don’t require installing long cables to connect. Instead, they communicate wirelessly with the NVR or router. However, they may require power, which means they need to be located near an electrical outlet or powered by batteries.
When choosing a 3MP wireless security camera system, it is important to consider factors such as the range of the wireless signal, the durability of the camera, and the storage capacity of the NVR. Some systems also offer additional features such as motion detection, night vision, and remote access through mobile apps or web browsers.

What is 3MP?

3MP refers to the resolution of the image taken by the camera, usually expressed as the total number of pixels in the image, also known as pixel density. In this case, 3MP means that the camera can capture an image of 3,2048 pixels, that is, the image has 1536 horizontal pixels and <> vertical pixels. Higher resolutions generally provide sharper images and better detail, but also require more storage space and cost more. When choosing a camera, you need to balance resolution and cost with your specific needs

merit

Compared with ordinary HD cameras or 720P/1080P surveillance cameras, 3MP cameras have the following advantages: Higher resolution:
3MP cameras have a total of 3,3 pixels per image, which is nearly 720 times that of 1080P and 3P HD cameras, so it can provide clearer and more detailed images.
Wider field of view: Under the same monitoring area, 3MP cameras have a wider field of view, can capture more detailed information, and are more powerful, which can fully cover the monitoring scene.
Clearer night vision: 3MP cameras use higher quality night vision sensors to provide clearer and more vivid surveillance images at night or in low-light environments.
Compared with low-resolution surveillance cameras, 4MP cameras can provide higher quality surveillance images and wider surveillance field of view, which is very helpful for surveillance scenarios that require more detailed information. Compared with 3K resolution cameras, <>MP cameras are more practical and economical in terms of price, storage and bandwidth costs, and can also provide a high-quality surveillance experience.

Pixel and resolution

A pixel is the smallest unit of an image, representing a small dot in an image, which can be understood as an atom of the image. Resolution is the number of pixels that describe the horizontal and vertical directions in an image, usually expressed in terms of the number of pixels, such as 1920×1080. It can be thought of as a statistical indicator of the number of pixels in an image.
In a display device, pixels occupy a physical space, and the size of this space can be described in terms of pixel density. Pixel density refers to how many pixels are in a unit of length, usually inches. Therefore, pixel density also affects the sharpness and detail of the image, and generally the higher the pixel density, the sharper the image will be.
However, it should be noted that the size of the pixel is determined by the physical characteristics of the display device and the pixel density, not by the resolution. Therefore, pixels cannot be equal to a specific resolution, but are described and processed as the smallest unit in an image.

Application scenarios

3MP wireless security cameras have higher resolution and clearer image quality than traditional cameras, so they are suitable for many different application scenarios. Here are some scenarios where a 3MP camera might fit:

Home security: 3MP cameras can be installed at the doorstep or indoors to monitor areas such as entrances and exits, hallways, or rooms to improve home security. Commercial security: Shops, offices, warehouses and other places can use 3MP cameras for monitoring, helping managers better understand the situation of the place, improve security and management efficiency.
Scenic spot monitoring: 3MP cameras can be installed in every corner of the scenic spot to ensure the safety and tourism experience of tourists.
Building monitoring: 3MP wireless security cameras can be installed on building exterior walls, parking lots, corridors and other areas to improve building safety and management efficiency.
Traffic Monitoring: 3MP wireless security cameras can be installed on the road to monitor traffic conditions and improve traffic management efficiency.

purchase

If you want to buy a 3MP wireless security camera, here are some shopping tips: Resolution:
First, you need to decide on the resolution you need. In general, a resolution of 3MP can already provide higher image quality, but if you need a higher resolution or more detailed image details, you can also choose a higher resolution camera.
Perspective: Different cameras have different perspectives. In general, the larger the viewing angle, the larger the monitoring range. Therefore, you need to consider the size of the area that needs to be monitored, and whether wide-angle monitoring is required.
Night vision: Night vision is important if you need to monitor in low-light conditions. In general, the better the night vision function, the better the camera will monitor at night.
Motion detection function: Some 3MP wireless security cameras come with motion detection function, which can automatically start recording when motion is detected, improving monitoring efficiency.
Storage and data sharing: The camera’s storage and data sharing capabilities need to be considered in order to store and access the data captured by the camera. Some 3MP wireless cameras can connect to cloud storage or view live video or playback history through a phone app.
Brand and price: Finally, you need to consider brand and price. Different brands of 3MP wireless cameras may have different features and prices, you can choose the camera that suits you according to your needs and budget.
