The Redvision CCTV Hub: a cost-effective and robust solution for construction site security
Most legacy CCTV systems were designed for permanent buildings with fixed infrastructure, including structured cabling, dedicated comms rooms and stable power. On construction sites, you rarely have that luxury. Common limitations include: Fixed network dependence. Conventional network video recorders and encoders expect a wired network. Getting fibre or copper to every tower or scaffold run is expensive and slow.Single-camera 4G routers. Basic cellular routers bolted to a pole might work for one camera but quickly become a bottleneck when you need multiple viewpoints.Analogue holdovers. Older systems still built around analogue cameras and encoders struggle to deliver the resolution and intelligence you need from an IP camera solution.Cable vulnerability. Exposed cabling is easy to damage accidentally with machinery (or deliberately by... Read More
How does an IP camera work?
An IP camera (internet protocol camera) captures, processes and transmits video over an IP network. Unlike older analogue devices, IP CCTV security cameras encode video inside the camera itself and stream footage to network video recorders (NVR), video management systems (VMS) or cloud services, making them suitable for scalable CCTV camera solutions. Whether you’re an installer specifying a CCTV camera system for a university campus, a security consultant designing perimeter protection for a prison or a facilities manager seeking better retail CCTV coverage, IP security camera systems are an essential part of modern video surveillance. This guide will explain the different types and functionality of IP cameras, where they add the most value and what to look for when specifying... Read More
PTZ security cameras: how they work and when to use them
PTZ security cameras pack a lot of capability into a single device. They can move automatically or by operator control, zoom in over long distances and process video directly inside the camera. But how do these cameras actually work, and when should you choose them over fixed cameras? Whether you’re a CCTV installer or a security manager planning protection for a university campus, city centre or high-security site, this guide will explain the different mechanical elements and functionality of PTZ security cameras, where they add the most value and what to look for when specifying or installing them. What makes PTZ security cameras different? At the highest level, a pan–tilt–zoom (PTZ) camera is an active device: it can rotate horizontally... Read More
Why are ONVIF cameras the safest choice for your CCTV system?
The short answer? To avoid vendor lock-in and future-proof your projects. ONVIF is a manufacturer-neutral set of specifications that define how IP cameras and other video devices and management systems communicate. Profiles group features so that integrators can match the functionality they need rather than relying on vendor-specific APIs. For installers, specifying an open standard at the design stage protects your client from painful, expensive rip-and-replace cycles. If your customer gets locked into a proprietary recorder or CCTV camera ecosystem (no ONVIF camera support), they can be forced into costly overhauls when a vendor changes strategy, discontinues firmware updates or — in the worst case — stops trading. To ensure long-term interoperability and competitive procurement, ONVIF compliance is also frequently... Read More
Are your CCTV cameras NDAA compliant?
They should be. Using non-compliant CCTV cameras can cost you contracts, create legal and financial liability, and damage your revenue and reputation. Government and many public-sector contracts now require suppliers and contractors to avoid covered vendors and components defined in Section 889 of the National Defense Authorization Act (NDAA). Getting this wrong can disqualify a bid, force expensive rip-and-replace work and expose your CCTV camera installation to regulatory and cyber risks. So, when you’re specifying a CCTV camera (or an entire security camera system) for a new site — whether a high-security government facility like a prison or a large-scale rollout for a university campus — always check it’s NDAA compliant. Why NDAA compliance matters for installers and integrators If... Read More
