This sPoE security system uses proprietary cables to provide both power and signal between your NVR and IP cameras, allowing you to install your cameras anywhere without worrying about nearby power outlets. It not only saves your time and money when installing, but also makes the cable layout neat and tidy. To get remote access, download the Zmodo app on your smartphone (iOS or Android). After setup, you can enjoy four cameras simultaneous viewing on the Zmodo app, and you can also view the NVR from any computer by using the Zmodo user website from any web browser and logging in with your Zmodo App account.
