Trigger Delay
Trigger delay, often referred to as trigger speed, is the interval between when a sensor detects an object and when the camera captures an image. A rapid trigger speed (ideally less than 1 second) is crucial for capturing fast-moving animals, as slower trigger speeds may result in numerous empty frames. The relationship between trigger speed and detection zone is significant; a wider detection zone can help compensate for a slower trigger speed. This is especially important for cameras placed along trails where animals may pass quickly.
Causes of Slow Triggering
Sensor Performance
The performance of the motion sensor is crucial for achieving optimal trigger speed. PIR (Passive Infrared) sensors can exhibit variable sensitivity, which affects their ability to detect motion. Additionally, sensors with slower response times will naturally result in longer trigger delays.
Environmental and Subject Factors
Various environmental conditions and characteristics of the animals being monitored can affect sensor performance and contribute to slower triggering:
Environmental Factors:
Temperature fluctuations can impact the ability of PIR sensors to detect temperature differences from the background. This may lead to delays or false triggers.
Dense vegetation and improper camera placement can obstruct the sensor’s line of sight. For example, vegetation may block infrared signals, reducing the area covered by the sensor and causing delays in detecting passing animals.

Subject Factors:
The size of the animal affects detection. Larger animals, such as deer, have a more pronounced temperature difference from the background, making them easier to detect. In contrast, smaller animals, like squirrels, may be harder to detect due to their smaller size and minimal temperature difference from their surroundings.
The speed at which an animal moves can influence the likelihood of capture. Fast-moving animals, such as running foxes, may pass through the detection zone too quickly for the sensor to capture them.
The temperature difference between the animal and its environment is crucial. For instance, in colder environments, animals with higher body temperatures, like bears, can be more easily detected due to the significant temperature difference from the background. In warmer environments, the smaller temperature difference may make detection more challenging, leading to delays.
Camera Settings and Storage Factors
Camera settings and storage factors significantly impact trigger speed:
Storage Card Performance:
SD Card Quality and Write Speed: The quality and write speed of the SD card directly affect trigger speed. Low-quality or slow-write-speed SD cards can result in data writing delays, increasing trigger time.
Detailed SD card precautions can be referred to in this article：FAQ about SD Cards
Image Quality and Write Speed: Higher-quality images require more time to write to the SD card, which can affect subsequent triggers. Faster write speeds and efficient image processing can help mitigate this issue.
Camera Settings:

(PIR) Trigger Sensitivity: Increasing trigger sensitivity can enhance the sensor’s ability to detect motion more promptly.
detection Delay: Reducing the time between shots can minimize the delay in capturing an animal.
Side Sensor Sensors: Enabling side sensors can provide early warnings, helping the main PIR sensor detect motion more quickly and reducing primary trigger delays.
Image and Video Capture: Simultaneous image and video capture can lead to trigger delays as the camera writes the image to storage before starting video capture.
Burst Mode: Using burst mode, which captures multiple high-quality images in succession, can lead to delays due to the time needed to write each image to storage.
Power and Equipment Aging
Power supply issues and equipment aging can also contribute to slower triggering:
Power Issues:
Battery Power: Low battery levels can degrade both sensor and camera performance, leading to slower trigger speeds. Regular battery checks and replacements are essential for maintaining optimal performance.
Power Stability: Unstable power supplies can cause inconsistent triggering, affecting overall camera functionality. Ensuring a stable and reliable power source is crucial for optimizing trigger speed.
Solar Panel Usage: Using solar panels can effectively address power issues and extend equipment lifespan. Solar panels provide continuous power, reducing reliance on traditional batteries and minimizing battery-related delays. They also decrease the frequency of battery replacements, contributing to the overall longevity of the equipment.
Equipment Aging:
Component Wear: Over time, internal components such as sensors, processors, and batteries can wear out and degrade. This wear can impact performance and trigger speed. Regular maintenance and inspections can help mitigate aging effects.
Technological Obsolescence: As technology advances, older equipment may become outdated. Upgrading or replacing equipment with newer technology can address issues related to aging and improve trigger speed.

The Impact of Network Transmission on Cellular Camera Triggering
For cellular cameras, network signal does not affect the trigger speed of the camera, but it does influence the speed and success rate of uploading images to the GardePro app after shooting is complete. If you are located far from the camera's placement, you may not be able to promptly determine whether the camera has triggered normally through the GardePro app's gallery.
In such cases, there may be instances where the camera has successfully captured images, but the GardePro app has not received the pictures or has failed to load them, typically due to network issues. Users simply need to wait for the signal to improve and check whether the camera is functioning properly.
Additionally, network instability may cause delays, affecting your ability to view the camera's captured content in a timely manner. Therefore, it is crucial to ensure good network signal coverage when selecting the camera placement.
