Knowra Camera trap Camera trap A remotely triggered camera records animals when they pass a location, usually without a person present. Motion or heat sensors commonly activate its camera and flash.
Passive infrared sensor : A sensor that detects changes in infrared radiation, often caused by a warm moving object. Many traps use its detection of animal heat and movement to trigger the camera.
Wildlife monitoring : The repeated collection of information about wild animals, populations, or habitat use. Camera traps provide a noninvasive way to monitor wildlife across sites and seasons.
Animal behavior : The actions and responses of animals, shaped by their biology and environment. Species movement and activity patterns affect whether animals encounter a trap.
Acoustic monitoring : The use of sound recordings to detect or study animals and other environmental sounds. Audio can detect vocal species that remain outside a camera's field of view.
Motion detection : The identification of movement within a monitored area by a sensor or imaging system. Movement is one of the main cues that starts a camera trap recording.
Wildlife population estimation : The estimation of animal population size or density from observations and statistical models. Repeated photographs can help estimate populations, especially when individuals have recognizable markings.
Species identification : The determination of an organism's taxonomic identity from observable traits or other evidence. Images may show only partial views, so identification can be uncertain.
Track and sign survey : A wildlife survey that identifies animals from footprints, droppings, nests, or other traces. Animal traces can reveal passage that a camera missed or could not identify.
Camera trap placement : The selection and positioning of a camera trap site to capture targeted wildlife activity. Position and angle shape which animals enter the detection zone and appear in images.
Occupancy modeling : A statistical method for estimating species presence while accounting for imperfect detection. Camera-trap records often miss animals that are present, making detection probability essential.
