Resolution dictates the clarity and detail of the captured footage. In 2025-26, common resolutions range from Full HD (1080p) to 4K (2160p) and even higher. Higher resolutions allow for clearer identification of individuals, license plates, and fine details, especially when zooming in. Look for cameras with good pixel density and advanced image processing for sharp, detailed images.

Night Vision

Essential for round-the-clock surveillance, night vision allows cameras to see in low-light or no-light conditions. This is typically achieved through infrared (IR) LEDs that illuminate the scene with invisible light. The range of the IR illumination (measured in feet or meters) and the quality of the image produced in darkness are critical factors.

Field of View (FoV)

The FoV determines how wide an area the camera can capture. A wider FoV means the camera can cover more ground with a single unit, reducing the number of cameras needed. Lens types (wide-angle, telephoto) and sensor size influence the FoV. For large areas, a wide-angle lens is preferred, while a telephoto lens is better for focusing on distant subjects.

Durability and Weatherproofing

For outdoor installations, cameras must be able to withstand environmental factors like rain, dust, extreme temperatures, and potential vandalism. Look for IP ratings (Ingress Protection) for dust and water resistance (e.g., IP66, IP67) and IK ratings for vandal resistance (e.g., IK10).

Storage Options

Recorded footage needs to be stored. Common options include:

  • Local Storage: MicroSD cards inserted directly into the camera. Offers convenience but limited capacity.
  • Network Video Recorder (NVR) / Digital Video Recorder (DVR): Dedicated hardware devices that store footage from multiple cameras. NVRs are for IP cameras, DVRs for analog. Offer larger storage capacities.
  • Cloud Storage: Footage is uploaded and stored on remote servers. Offers accessibility and off-site backup but usually requires a subscription fee.

Motion Detection and Alerts

Most modern cameras feature motion detection, which triggers recording or sends alerts when movement is detected. Advanced systems in 2025-26 offer customizable motion zones, person/vehicle detection, and intelligent alerts to reduce false positives from environmental factors like falling leaves or passing cars.

Audio Capabilities

Some security cameras include built-in microphones for capturing audio. Two-way audio, allowing for real-time communication through the camera, is also a feature found in many modern devices, useful for deterring intruders or communicating with visitors.

Many cameras integrate with mobile apps for remote viewing and control, and some support protocols like ONVIF for broader compatibility with NVRs and VMS (Video Management Systems).

How Security Cameras Work

At their core, security cameras capture light through a lens and convert it into an electrical signal. This signal is then processed and either displayed in real-time or recorded. The process can be broken down into these fundamental steps:

  1. Image Capture: A lens focuses light onto an image sensor (like a CMOS or CCD sensor). This sensor converts the light into digital data.
  2. Signal Processing: The digital data is processed to create a video stream. This involves adjusting color, brightness, and contrast.
  3. Transmission: The video stream is transmitted. For analog cameras, this is via coaxial cable to a DVR. For IP cameras, it's via an Ethernet cable or Wi-Fi to a network, then to an NVR or directly to the cloud.
  4. Recording/Storage: The video stream is recorded onto a storage medium (SD card, NVR/DVR hard drive, or cloud server).
  5. Viewing: Footage can be viewed in real-time or played back from storage. Modern systems allow remote viewing via internet-connected devices like smartphones, tablets, or computers.

Advanced features like motion detection involve algorithms that analyze the video stream for changes, while AI-powered cameras utilize complex machine learning models to interpret the visual data for specific object recognition or behavioral analysis.
