Today’s security camera market is a fast-growing field with a variety of features to choose from. For starters, this can be confusing at first, especially when buying a multi-camera system. Which features are the most important, or more importantly, which are the most important for your security needs? This article will try to explain some of the features of these security cameras with some explanations to help you better understand What features to consider when purchasing a security camera system.
1) Video resolution
One of the first and most important things to consider when choosing a security camera is video resolution. Older cameras use standard definition analog resolution, which is still used today. Due to older technology, analog cameras tend to be cheaper and provide the ability to record for longer periods of time while using less memory / hard disk space. However, analog cameras lack the fine details that HD cameras have. Megapixels, or high-definition video, can produce images several times larger than simulated images, which allows them to capture larger details, including faces, tattoos, and other details, if these videos are later used as evidence, These details may be important.
The higher the pixel value of the camera, the more detail you can tell from the lens. Keep in mind that when the resolution exceeds 1080p (high definition), the maximum frame rate will decrease. This is because each frame rendered at extremely high resolution is encoded with exponentially more memory and network bandwidth.
2) Infrared night vision mode
Some security cameras have built-in functions for viewing in total darkness using infrared. Its working principle is that the infrared light (invisible to the naked eye) emitted by the infrared light surrounding the camera lens is realized. The human eye cannot see infrared light
When the light goes out or the sun goes down, there is not enough visible light to hit the camera’s image sensor, and these infrared LEDs will turn on automatically. Part of the infrared light emitted by the camera is reflected back when it hits the target, and the remaining infrared light is captured by the infrared sensor, which is usually located directly above the camera lens. Infrared images often lack color, but allow small, important details to be clearly seen.
3) Wired and wireless
Most security cameras now use wireless wifi access, which eliminates the trouble of wiring. Easy installation. Most of the wireless wifi access is in the 2.4G frequency band, so ordinary 1000M wireless routers can be easily implemented.
4) cloud storage
The most important thing about the security camera is that there is an accident, and you need to retrieve the video to see it. The camera has a recording method. One is an SD card, which is inserted into the camera. One is cloud storage. You only need to pay a small monthly fee or even free, and you can view it anytime, anywhere through the mobile APP. The advantage of cloud storage is that when the camera is damaged or lost, it can still be easily viewed by mobile phone.
