It all depends on the cameras selected. Surveillance trailer cameras typically record in high-definition resolutions, ranging from 1080p (Full HD) up to 4K (Ultra HD), depending on the system configuration.
-
1080p (Full HD, 1920×1080 pixels):
-
Standard for most trailers, offering clear detail for identifying people and vehicles.
-
Provides good balance between image quality and storage requirements.
-
-
1440p (2K, 2560×1440 pixels):
-
Offers higher clarity and detail, useful for recognizing faces, license plates, or distant activity.
-
Slightly increases storage and bandwidth needs.
-
-
4K (Ultra HD, 3840×2160 pixels):
-
Premium option for extremely detailed images, ideal for large areas or critical security zones.
-
Allows digital zooming without losing clarity, which is important for PTZ and auto-tracking cameras.
-
Requires larger storage capacity and higher network bandwidth for live streaming.
-
-
Specialty Cameras:
-
Thermal cameras produce heat-mapped images, which do not rely on pixel resolution the same way as visible-light cameras but can detect objects at long distances.
-
License plate recognition cameras are optimized for high resolution at targeted ranges to capture alphanumeric details clearly.
-
-
Recording Modes:
-
Most trailers allow continuous recording or motion-triggered recording, with resolution settings adjustable to balance image clarity vs. storage/bandwidth.
-
Cloud storage or local NVR/DVR systems may compress footage (e.g., H.264 or H.265 codecs) to maintain manageable file sizes without sacrificing necessary detail.
