A dog camera like the Eyenimal model weighing only 35 grams and measuring 6 x 4.5 cm is not much bigger than a regular collar pendant. The device has a memory chip with 4 GB and can record in AVI format for up to 180 minutes. You can transfer this to your PC via a USB cable. The camera system is compatible with all Windows software version 2000 and higher, as well as Linux and Mac OS 10.x. With a resolution of 680×480 pixels and 29 frames per second, you get a quality video that is worth watching. Sound is also recorded via the built-in microphone. As with other technical devices, the dog camera should not be used in negative temperatures or rain and wet conditions. Exceptions are cameras with a corresponding weatherproof housing.
