Integrate Grandstream GDS3720 Series Video Door Station with Speco NVRs
The Grandstream GDS3720 series video door stations offer standalone access control via the Secure Access app, allowing users to control who can access a facility and at what times. They include a 4MP camera that can be viewed live from the app and can record access events to a local micro SD card. They can be made an extension of a Grandstream UCM phone system, allowing users to grant access to visitors who push the doorbell button. They can also be added to a Speco NVR for 24/7 recording.
