Each earned three out of a possible three stars from AV TEST. The company found "no noticeable vulnerabilities in the communication of the camera and app" in each camera, meaning that they're about as secure as IP cameras can get. However, AV TEST noted "optimization potential" for each camera's companion mobile app, suggesting that the user interfaces are not as user friendly as they could be. This is not a trivial issue — the more obtuse a UI, the less likely a user is to take charge of his or her own security, which could lead to vulnerabilities down the road. The D Link DCS 2132L and the Gigaset Camera scored only one star out of three, with potential vulnerabilities in just about every category tested. The only exception was that external camera controls were "secured" in the Gigaset. In particular, AV TEST cited " transmission of information" and " image transmission" in the D Link, and "vulnerable encryption" and "unsecured transmission of individual images" in the Gigaset. Readers may remember that the U. S. Federal Trade Commission sued D Link earlier this month for allegedly poor security in its routers and security cameras. The remaining cameras — the Netatmo Welcome, the Smartfrog Cam and the Withings Home — all got passable marks, with a mix of "secured," "vulnerable" and partially vulnerable features.

If that weren't reason enough to choose a secure camera, unencrypted transmissions could also leak your Wi Fi password or router credentials, giving an attacker complete control over your home network.
