The U7 Pro XG brings WiFi 7, a 10 GbE PoE+ uplink and a silent metal-heatsink design to UniFi’s flagship ceiling AP line. Full specs, an interactive 3D model, comparisons and FAQs.
SIP trunking replaces traditional PSTN and ISDN telephone lines with an internet-based voice service, letting businesses make and receive calls over their existing data connection. It reduces line rental costs, simplifies number management, and scales instantly without waiting for a carrier to provision physical circuits. This guide explains how SIP trunking works, what you need to get started, and how it compares to hosted PBX and UCaaS.
Power over Ethernet has transformed IP camera installations by delivering both data and electrical power over a single network cable. No more running separate mains power to every camera location, no more electrician call-outs for each new device. But a well-designed PoE camera network requires more than just plugging cables in — you need the right switches, proper VLAN segmentation, bandwidth planning, and protection against the elements.
When planning a surveillance system you will inevitably face the question: should we use a standalone NVR appliance or deploy a software-based Video Management System on standard server hardware? Both approaches record, store, and play back IP camera footage, yet they differ significantly in scalability, cost structure, flexibility, and complexity. This article compares the two so you can make an informed decision for your next project.
Choosing the right resolution for your IP cameras is one of the most important decisions in any surveillance project. Higher resolution captures more detail, but it also demands more bandwidth, storage, and processing power. This guide walks you through the most common IP camera resolutions, explains pixel density and identification distance, and helps you match the right resolution to each area of your site.
RAID (Redundant Array of Independent Disks) is a fundamental storage technology that combines multiple drives to improve performance, provide redundancy, or both. Understanding the different RAID levels and their trade-offs is essential for anyone designing server or storage infrastructure. This guide covers every common RAID level in detail.
Virtualisation has transformed modern IT infrastructure, allowing organisations to run multiple operating systems on a single physical machine. At the heart of every virtualised environment is the hypervisor. This article explains the two types of hypervisors, compares the leading platforms, and helps you decide which is right for your needs.
Choosing between NAS, SAN, and DAS storage architectures is one of the most important infrastructure decisions an organisation can make. Each approach offers distinct advantages in performance, scalability, and cost. This guide breaks down all three, compares protocols and use cases, and helps you pick the right fit for your environment.
Recovery Time Objective (RTO) and Recovery Point Objective (RPO) are two of the most critical metrics in disaster recovery planning. Understanding the difference between them, and how to calculate each for your organisation, is essential for building a backup and DR strategy that actually protects your business.
The 3-2-1 backup rule has been a cornerstone of data protection for over two decades: keep three copies of your data, on two different media types, with one copy stored offsite. In an era of ransomware, cloud storage, and immutable repositories, the rule has evolved but its core logic is more relevant than ever. This article explains the original rule, modern variations, and how to build a backup strategy that actually works when disaster strikes.
