Montasser, can you elaborate on your setup? Where is the recorder? Where is the ATM? What separates them?
Generally, ATM cameras are hardwired direct to the recorder, either a small form factor one in the ATM machine(s) or to the facility on site.

recorder at city , ATM on the highway 20 miles away , we've many ATMs in other remote locations need to be connected to the same recorder.
also that camera should give overview from 8M height also the expected bandwidth will be 1.5Mbps
there is no infrastructure like fiber optics cables or any wired communication way , we've to use a practical wireless communication but not satellite
Edge recording would be far more reliable in this case. Like John had mentioned you still need connectivity and mobile would be the way to go. You could consider programming the camera to trigger an output which would in essence reboot the current modem for you. Just a thought although this may complicate things long term. Short term- find a reliable modem. Try Sierra Wireless modems as they work extremely well.

This can be done with Ubiquiti AirMax products. The size and scope is hard to tell from your basic info. Depending on how closely the ATM's are to each other, elevations of each site, etc will make a large impact on viability and cost.

In our experience, 20 miles on existing Ubiquiti products would require absolutely perfect conditions to achieve. At best in a highly rural area with zero interference (-95 dBm), and no trees or buildings in the FZ, each location would likely need at least 80' towers and 3' parabolic dish antennas (assume no uptilt). If all of the above conditions hold true, expect roughly 15 - 25 Mbps aggregate with significant latency.
We've had good experiences with Ubiquiti but at that distance your best options are to look at the PTP650 line from Cambium. Significantly better interference rejection, NLoS and a much higher modulation rate. It certainly requires a greater initial investment but the performance and reliability are second to none.
John is correct, the mobile carriers may offer the best solution. In the US, the 24 hour disconnection problem can be resolved on "the V" carrier by purchasing a static IP and using a good modem such as the Cradlepoint COR600.
PTP wireless is likely not a realistic solution for this use case but regardless, I hope this helps. Good luck.
