The MobiCam Digital DL Portable Multi-Camera Audio/Video Monitoring System is a versatile, handheld monitoring system--equally ideal for baby monitoring and do-it-yourself surveillance in the home. Both the high-resolution, LCD monitor and camera are portable, making it easy to carry them with you from room to room. Voice-activated audio and video alert you to changes in your home, office, or nursery, and night-vision mode ensures that you can see what's happening outside or after your newborn baby is asleep. With the ability to incorporate up to three additional cameras (sold separately), the MobiCam Digital DL offers peace of mind and security in almost any environment.
