How does it send email notifications if there is no internet access? Does it host own email server and can send emails only to clients on the local network? Do I need to host a local email server like EmailEnable and then the NVR can connect to it as a client and send emails to other local clients?
Is there a way to connect a 2G/3G/4G module in order to send alerts to a mobile phone?
Under “Trigger Events” in
I see “Buzzer, Voice Prompts, Email, Snapshot, Recording, Alarm Out, PTZ Activation, etc.”. Does “Alarm Out” mean I can connect VNR to my existing alarm central that does include a module for sending SMS’s? I kind of feel this can’t work out of the box and would require that both systems have a matching protocol.
Can the software of these NVR’s be extended in any way? I understand everything is closed source but is there any API at all I can use to connect other devices to send and receive signals from NVR?
Looking into "Interoperability ONVIF 2.4, SDK, CGI" now
