The Zetronix Nano 4K 4G LTE is a compact, modular camera core built for security professionals, field investigators, and property owners who need eyes on a location where there is no Wi-Fi. Insert a SIM card and the Nano connects to any major 4G LTE cellular network, streaming live 4K Ultra HD video straight to your smartphone from anywhere in the world. A 100MB SIM card comes in the box, with enough data to last for up to 30 days, which is a convenient way to get the product started before you switch to a SIM of your own. Replay footage saves locally in efficient 1080p to a MicroSD card of up to 256GB, so weeks of video stay on your own memory card. Eight tool-free snap-on mounts let you redeploy the same core in seconds: lapel, vest, and belt clips for visible on-body documentation, plus magnetic and adhesive bases, an enclosure faceplate, a swivel wall bracket, and a tripod thread adapter for fixed camera builds. A rechargeable lithium-ion battery delivers up to 6 hours of runtime, or run it continuously on USB or AC power. Motion detection sends alerts to your phone, optional date and time stamps keep your records organized, and a low-light sensitive lens with a 90-degree wide viewing angle captures clear detail across a room. Intended for lawful use only: overt on-body recording by security and field professionals, or monitoring of property you own or manage.
