Remote Access via Mobile/Cellular/Satellite Internet

In order to connect to any server over the Internet (such as SecuritySpy’s built-in web server for remote access to your CCTV system), the server must be exposed to the Internet via a public IP address.

Most standard home and commercial Internet connections (Fibre, ADSL, Cable) provide a public Internet address, which makes setting up remote access to SecuritySpy fairly straightforward, as described in the Remote Access section of the SecuritySpy Installation Manual.

However, Mobile/Cellular Internet connections (i.e. those that use a 3G, 4G or 5G modem to connect wirelessly over the cellular network) are becoming increasingly common, as their speed and reliability increase and costs decrease. Unfortunately, most mobile Internet connections do not provide a true public IP address, but rather provide a private address within the Internet provider’s network (this is called Carrier-Grade NAT). Therefore it is not possible to set up remote access in the same way. Typically, this is the case with Satellite-based Internet connections as well.

Some mobile Internet Service Providers (ISPs) can provide a true public IP address for an extra fee, but not all do.

The solution to this problem is to use a service called ngrok, which allows you to set up a secure tunnel to your server in order to provide access to it from the Internet. Here’s how it works: Continue reading

Protecting Yourself from Server Outages

When your SecuritySpy system is running autonomously at a remote location, there are a number of measures you can put in place to help ensure reliable operation, and to remotely control it if necessary, avoiding the need to physically visit the site to resolve any problems. Problems that may occur include computer crashes and router problems. Although such problems are rare, it is a good idea to implement some or all of the below suggestions, especially if the site is far away and a visit in person would be inconvenient.
