Rhinoceroses are a rare species, and it’s humans that are to blame for that. These herbivorous mammals have been sought out for centuries for their horns — keratin extensions of their noses — which are believed to have healing properties in traditional Asian medicine. The Western medical community has disproven that this is actually true, but many people in China and Yemen still try to acquire rhino horns on the black market.

Keeping rhinos safe from poachers who sell to the black market has been quite a challenge — particularly in the areas where rhinos are found in Africa and Asia. However, according to io9 and the WWF, the Javan rhinos in Indonesia’s Ujung Kulon National Park have just gotten an upgrade in security with the quadrupling of cameras. The former count of just 40 cameras is now 160, thanks to a donation from the International Rhino Foundation.

There are less than 50 Javan rhinos left, which means there are three cameras for every existing one. It should go without say that the cameras aren’t always where the rhinos are, but the more there are, the more rhinos can be observed, along with other animals — and potential threats to their livelihood. And what’s not to like about watching a rhino on camera?
