Today, video monitoring company Cernium announced that its Archerfish Quattro system is now available on The system, which comes with two color weatherproof cameras, sends video alerts to your mobile phone or e-mail when it detects unusual movements. The coolest thing about the system is that it can distinguish between cars and humans and, say, a stray cat darkening your company's doorstep, so you won't get bombarded with unnecessary alerts. The system costs $1,699 for two cameras and a three month subscription to the Archerfish account management portal. After the trial ends, the subscription is $7.99 a month for one device and $3.99 for each additional device.
