Am I able to connect any brand of wifi ip surveillance camera or does it need the be the fortress brand?
Hello Bryan, It would need to be the Fortress brand in order to connect, the 3rd party cameras would not be compatible with our app. Thanks, Jessica Customer Service Manager
Do I need a SIM card with this system? Also, do I need a landline for the calling capabilities?
Hello Melanie, The S03 system only works with a phone line or WiFi, it is not compatible with the SIM card. If you want it to call out it will need a phone line. Thanks, Jessica Customer Service Manager
