Trail cameras have come a long way, improved sensors, improved AI species detection. WiseEye cameras are leading the way. Check out the rat video here in the video section β†’ Gallery

Cuddeback CuddeLink Wireless Trail Camera System
Is anyone using these cameras (from USA !)? This system of cameras link together with all of the photos being sent to one base unit.

We are interested to find out from any groups who are currently using the Cuddeback Link system - how well it detects smaller animals (rats, hedgehogs, stoats etc), and any pros and cons you may have encountered. Plus how many cameras you may be operating.
Ideally we would like to set up more cameras on some traps to review predator / trap interactions, plus monitor some of the bird species in a local wetland.
Thanks for any feedback.
