The security camera system industry is being disrupted by 4K Ultra HD technology. In 2017, fewer than 1% of the global security camera market, but by 2022, one in five security cameras will be capable of 4K resolution, as per one of the security camera warehouse provider we spoke to, GetSCW. Here are 10 of the top reasons why the demand for 4K security equipment is growing so rapidly.
- Superior Resolution
Resolution represents one of the top features buyers demand from cameras, and the superior resolution of 4K makes it a compelling choice. Where traditional HD resolution provides a resolution of 1,920 x 1,080 pixels, 4K Ultra HD security camera systems bump this up to 3,840 x 2,160, equivalent to four times the pixels.
- Crisp Detail
Ultra HD resolution empowers 4K cameras to capture tiny details that would be missed by lower-quality cameras. Shapes are clearer, colours are more vivid and contrasts are sharper. This improves your chances of capturing critical surveillance details, such as facial features, hair and eye colour, and license plate numbers.
- Refined Zoom Capability
4K’s ability to capture small details can be further enhanced by Ultra HD cameras that include advanced zoom capability. The Lorex line of 4K security camera systems includes a limited number of select cameras with 4 times optical zoom capability. This means that in contrast to cameras that only use digital zoom, the optical zoom lens mechanically adjusts for a sharper image. Combining optical zoom with 4K Ultra HD resolution produces a superior image than optical zoom used with an HD camera.
- Automated Focus
Keeping objects in focus has been a problem for traditional security cameras. Today’s leading 4K cameras use smart focusing to automatically adjust to the required focal length. This ensures that details always stay crisp.
- Real-time Recording Rates
Low frame rates make video images look choppy, while higher frame rates capture motion more smoothly. All Lorex 2K and 4K cameras use a frame rate of at least 15 frames per second (FPS) to ensure that on-screen motion looks realistic and not jerky, and a few select 4K Noctural cameras even use 30 FPS.
- Infrared Night Vision
Ultra HD resolution helps 4K camera provides superior night vision. Nocturnal 4K security cameras, for instance, use high-powered infrared LED lights to illuminate the area in front of the camera lens. This lets the camera pick up details that would be invisible to the naked eye.
- Color Night Vision
Today’s best Ultra HD cameras can even support Color Night Vision. By adding external lights around the camera lens, Color Night Vision cameras can capture colour details even in very low-light conditions, with a full range of colour, high detail and strong contrast. In full darkness, the camera reverts to black-and-white infrared to ensure picture quality.
- Audio Integration
4K cameras don’t have to be limited to visual surveillance. The Lorex 4K line includes cameras with built-in microphones. Capture sounds as part of your surveillance, or use your 4K camera to let visitors talk to you remotely.
- File Compression
Because 4K Ultra HD footage records so much information, it can take up a lot of file space. 4K cameras use High-Efficiency Video Compression (HEVC or H.265) to reduce file size and optimize storage. This compressed footage then gets sent to a Network Video Recorder (NVR) for convenient storage and retrieval.
- Easy Installation
Installation can be one of the more expensive features of traditional security camera systems. Some 4K cameras are designed to be easy to install. Some models only require a single CAT5e cable with Power over Ethernet (PoE) to connect to a compatible NVR. Durable housing allows for safe outdoor installation.
