How Does Remote Video Surveillance Work? Full Guide

In the Internet of Things world, it’s no surprise you can remotely view your video surveillance system even when you’re not at home.

Your video surveillance network, though closed to the rest of the world, has to be accessible to you from wherever you are, so your security camera installer has to set up your network to allow that.

This is done by configuring your Local Area Network to accept Internet traffic through certain authorized ports, allowing remote video surveillance.

But how does remote video surveillance work without letting everyone into your surveillance system? Read on to find out.

How Remote Video Monitoring Works 

Remote video monitoring allows you to access live feeds from your CCTV security cameras using a laptop or mobile device, no matter where you are.

Instead of hiring security guards for CCTV monitoring, you can conveniently view the surveillance footage using mobile devices and other gadgets with remote CCTV monitoring.

Surveillance cameras are typically connected to a local network or the internet, allowing authorized users to access the live video feed and recorded footage from remote locations. These digital cameras capture video footage transmitted over the internet to a central monitoring station or cloud-based server.

Video footage is transmitted in real time or stored on a server, cloud-based, or video analytics platform for later retrieval. Advanced remote surveillance systems may include features such as motion detection, artificial intelligence, alert notifications, and access control. 

Live remote video monitoring provides a convenient and effective way to secure properties, businesses, and public spaces from virtually anywhere with remote video cameras and an internet connection.

Remote CCTV monitoring works by installing CCTV cameras equipped with network connectivity at desired locations. Using a secure login, authorized users can access the live video monitoring feed and recorded footage remotely via computer, smartphone, or tablet.

An Introduction to IP Addresses

Every Internet Protocol device has an IP address that routes requests and replies to the right place. IP addresses are similar to telephone numbersnumbers – a series of digits used to identify the device a transmission is sent to. The most common protocol today is IPv4, but a longer version called IPv6 is also available.

There are two basic kinds of IP addresses, dependent on what kind of network they’re used on. Small, local wireless networks like your home or business connection based around your router and modem use private IP addresses. The other side of every router has a public IP address, which others can use to access a server or website accessible to the public.

Live Video Monitoring Through Private IP Addresses

Every device on your local network has a unique IP address. These are generally pulled from a pool of numbers and assigned randomly as devices come on and off the network.

Addresses on your Local Area Network are generally in a designated range – a common range is to Your router often appropriates the address, and all your other devices follow. You can assign a device a permanent IP address for your IP cameras, which lets you reach that device at any point as long as you remember what that address is.

Public IP Addresses

From outside your network, your router is visible through a different IP address that your Internet provider assigns. Small businesses and residential networks have dynamic addresses that change periodically based on power fluctuations and outages, so your public IP address might differ from yesterday’s. It is important to note that video surveillance works.

This presents a problem if you want to view your video surveillance system remotely. You can’t check your network’s public address unless you’re on it, so you need a way to reference it without constantly checking it.

Understanding a DDNS is crucial to understanding how video surveillance works. After setting up port forwarding and DDNS, you can enter a domain name into an Internet browser and log into your NVR or Video Management System just like you would when you’re on the network.

Getting Remote Video Monitoring to Work Through Port Forwarding

Simply entering your DDNS into a browser won’t necessarily get you to your NVR—you’ll have to tell your router to let certain traffic through the firewall and which device to send it to. This is done through port forwarding, which assigns specific ports to specific devices on your network.

Any traffic requesting those ports will be let through the firewall and into the device, allowing you to remotely interface with a computer or server on your local network. When you set up DDNS, you’ll generally be routed to port 80 by default, but traffic using the standard http:// Internet protocol will be sent through port 8000.

Once your network has configured the settings, your device needs to be configured to allow remote viewing of your video monitoring system.

Video Surveillance Integration

Integration of security systems offers a complete solution for securing your property. Security cameras provide live feeds and recorded footage that can be accessed remotely via mobile apps or web portals. Since the control room allows authorized personnel

Trained professionals monitor feeds in real time, with motion sensors triggering alerts and recording movement. Integration with a video alarm activates alerts and notifies authorities of suspicious activity as seen on live or recorded video. Mobile apps and web portals allow remote access to live video feeds and recorded footage.

Advanced analytics detect anomalies, while cloud storage ensures secure video data storage. To enhance security, you can use two-way audio for real-time communication and integration with access control systems to track movement within premises.

Remote PTZ control adjusts viewing angles and tracks objects or individuals. With remote monitoring, you can monitor any unusual activity from anywhere with internet access.

How secure is remote monitoring?

Security measures such as encryption, password protection, and secure authentication protocols are typically employed to ensure the security of video monitoring systems. 

It’s essential to follow cybersecurity best practices to minimize the risk of unauthorized access to video feeds and recordings.

Also, trained security professionals can team up with security guards and other security personnel to avoid false alarms and provide immediate response and enhanced security solutions.

What happens to the recorded footage when remote monitoring is used?

Video monitoring systems record footage stored locally on a network video recorder (NVR) or remotely in the cloud. 

Recorded footage serves as evidence in case of investigations, so the security team should keep the recording devices’ data for around 90 days. Also, the retention period for recorded footage may vary depending on security system settings and storage capacity.

How do you set up a remote surveillance camera? 

First, choose a CCTV camera with internet connectivity to set up a remote surveillance camera for video monitoring. Install the CCTV cameras with an alarm system in the desired location and connect them to your local network router. Configure the camera’s settings through a web browser or dedicated software, ensuring proper resolution and security features. 

Enable remote access by setting up port forwarding or using a dynamic DNS service. Secure the CCTV camera with strong login credentials and encryption. The security team can test the CCTV systems by accessing the video feed remotely from a computer or smartphone.

Key Takeaways

Remote video monitoring offers a powerful means of enhancing security within your property from anywhere in the world. Using CCTV cameras with an alarm system, footage is captured and transmitted over networks, allowing remote access via computers, smartphones, or other devices.

Whether you’re ensuring public safety, monitoring your home or business, or keeping an eye on remote locations, video monitoring provides peace of mind and security at your fingertips.
