A cellular game camera would typically store all images on the SD card even if they are not going to be sent wirelessly.
Full resolution images are stored on the card, while users only get compressed images usually sized at 640×480 resolutions.
Thumbnails or low res images are one of the main concerns users have about wireless trail cameras, nevertheless it is important to find out the cost of getting full resolution images before deciding which device to buy.
In the worst case scenario, the cheapest option could be to pull the flash card out the camera and download all high quality pictures to a computer or any device that has a memory card reader, however the whole idea behind having a wifi trail camera is to get the images sent to one’s mobile device, which is accomplished even when lower quality images are sent.
Low VS high resolution images
Low resolution images provide a good expression of what the high resolution image captured. Although they are lower in quality they are viewable images, and for less money users are able to receive much more images sent to them wirelessly, so don’t be carried away just because of this.
While in some cases it may have no cost, certain brands may have data packages where consumers can choose how many thumbnail images they´ll like to receive per month at a certain cost.
In contrast, full resolution images are of much higher quality. They are megapixel shots, depending on the device´s capacity (8MP, 10MP, 12MP, etc), and allow much clearer viewing and zooming in full quality of the subject or animal that triggered the cam.
Although all images are stored in their highest resolution on the internal card, they can also be requested via WiFi depending on the company, who may also have a cost for individual or group of images.
Tips to consider about poor picture quality
At some point users may experience troubles with images either appearing dark or bright. Here are some useful tips to consider:
- If night images are dark:
Verify if the battery power indicator is full.
Review the user´s manual which specifies what is the ideal flash range since targets could appear darker at further distances
- If day images appear too dark or too bright:
Verify if the camera is not focused at the sun or other light sources
- If night images are bright:
Ensure the device is directed to the correct target area and keep in mind that if you have an IR flash cam and the target is between 3 meters of the camera certain pictures may come out bright
- If you are repeatedly receiving red or green images:
It could be due to a sensor problem, which may require service from the vendor
- If your pictures appear with stripes or marks:
A combination of low lighting conditions and rapid moving targets could cause these stripes. Read your manual to see if the camera can be changed from a higher to a lower resolution, which may render better results
Video problems are also related to this subject, and generally the same tips can be considered in application, correction or improvement of its quality; however if you notice that videos are coming out shorter than the length you previously configured it could be due to a full memory card.
