When shopping for 4K resolution security cameras, consider the following key features to ensure you choose a system that meets your needs:

- Resolution.

4K resolution provides ultra-high-definition video quality, offering four times the detail of 1080p Full HD. This is especially important if you need to identify faces, license plates, or other fine details.

- Night vision.

Look for cameras with infrared (IR) LEDs for night vision. The range of night vision can vary, so choose a camera that can cover the area you need to monitor in low-light conditions. Some 4K cameras also offer color night vision, which can provide more detailed images in the dark.

- Field of view.

The field of view (FOV) determines how much area the camera can cover. A wider FOV is useful for monitoring large areas, while a narrower FOV may be better for focusing on specific points of interest.

- Motion detection.

Many 4K security cameras come with built-in motion detection, which can trigger recording or send alerts when movement is detected. Some advanced cameras also offer human and vehicle detection to reduce false alarms.

- Two-way audio.

Cameras with two-way audio allow you to communicate with people on the other end, which can be useful for monitoring pets, talking to delivery people, or deterring intruders.

- Storage options.

Consider how the camera stores footage. Some cameras offer local storage via an SD card, while others rely on cloud storage. Cloud storage often requires a subscription but provides the convenience of remote access to footage.

- Weather resistance.

If you plan to use the camera outdoors, make sure it is weather-resistant. Look for an IP (Ingress Protection) rating, which indicates the camera's resistance to dust and water. For example, an IP65 rating means the camera is dust-tight and protected against water jets.

- Connectivity.

Most modern 4K security cameras connect to your home network via Wi-Fi, but some may also offer Ethernet connectivity for a more stable connection. Ensure the camera is compatible with your existing network setup.

- Smart home integration.

If you have a smart home system, look for cameras that can integrate with it. Many 4K cameras are compatible with popular smart home platforms like Amazon Alexa, Google Assistant, and Apple Home Kit.
