Features of 4K Security Camera Systems you should Look out for.

Number of Channels

Security camera systems come with a range of features. There are 1, 4, 8, 16, 23, and 64 channels available. Eight-channel NVRs can handle up to 4 cameras while sixteen-channel NVRs can handle up to 2 cameras.

The number of channels a security camera system has is determined by the number of cameras you will need. There are many factors to consider, such as whether or not you want wireless connectivity and what kind of coverage area your home needs.


DVR stands for Digital Video Recorder, which is used to process the video at the recorder. NVR refers to Network Video Recorder, which processes the video on camera itself. While DVR needs to process the video at a time, NVR does it without delay.

Wired vs Wireless

4K security camera systems come in two types: wired and wireless. Wired cameras are connected to the power source and internet by a cable, whereas wireless cameras are connected to the internet over Wi-Fi. Wire-free security camera systems have battery-powered and connect via Wi-Fi as wireless cameras do.

Night Vision

Night vision cameras are able to automatically activate in dark or low-light conditions. Color night vision allows for increased clarity of images when capturing video footage. The best 4K security camera system should have a wide-angle lens, HD resolution, long battery life, and a built-in microphone.

Camera Resolution

Some cameras might advertise 4K but you only get 1080p video quality. The camera’s sensor should be at least 8 megapixels and 12 megapixels for 4K resolution live viewing and recording.

Performances in Adverse Conditions

Security camera systems should provide good performance in adverse conditions. The 4K cameras that are available today don’t perform well under harsh weather, such as heavy rain or snow.

Do you need a 4K monitor for 4K security cameras?

4K security camera systems need a 4K monitor to get the best out of your system. The quality of life you’ll be able to have with a 4K monitor is far superior to what you can do if you use an HD or LED/LCD screen. If it’s not clear, the amount of pixels on your screen determines how well it will display colors and images from both cameras.

It’s IP67-rated and features night vision up to 120 feet, so it can withstand any weather condition or lighting situation.
