2024 has flown by and is nearly over! YellowsBest thanks you for your interest, enquiries and support during the year.
Now into our 10th year of business, we look forward to continuing to assist in “Keeping Customers Operational” with Business Development activities, Enterprise Support services, Sustainable Systems maintenance and supply of Technologies and Products solutions throughout the New Year.
We wish you a very Merry Christmas, and look forward to hearing from you again in 2025.
Over the last nine years, @YellowsBestLtd has sought out new, surplus and refurbished products and spare parts to assist with the aim of supporting Customers to maintain rather than replace their infrastructure networks, and as we enter our landmark tenth year, we continue to do so.
The alternative of wholesale replacements requires prohibitive investment costs and long project timescales to implement. And it can be the case that suggested replacements cannot provide equivalent operational lifetimes which therefore become obsolete faster than existing deployments.
Given the investment that has been made over many years, coupled with the fact may operational requirements have not changed, it makes sense to keep systems in place. By suppling spares, offering repair services and technical assistance, we are able to support these aims.
Eventually, it does become necessary or desirable to undertake network refreshes. Often, we can help evaluate, source and implement suitable systems.
As discussed recently at the Engineering Design Show, we are able to utilise the capabilities of a network of local manufacturers to replicate and if necessary reverse-engineer components and products to meet exacting performance requirements.
When replacing existing networks, we are able to offer to Remove, Resell and/or Recycle existing equipment, generating revenue from the ‘Value Recovery’, and importantly ensure that items are disposed of in the most ethical and environmentally respectful way.
Certain product families continue to prove their excellent availability and reliability, and we are fortunate to continue to be able to provide stock of many of these items, either in new, surplus or refurbished condition.
Examples of such products follow; should there be anything specific you require, please do not hesitate to get in touch; we look forward to hearing from you!

Wonderful Sporting Competition!
The summer of sport continues with the fabulous event that is the Olympics, bringing together competitors from nations from all over the world. This time hosted in Paris, showcasing the widest diverse collection of the most popular together with some lesser known sporting activities.
Following our favourites!

Whatever the sport you’re interested in and whoever you follow, good luck and best wishes for an exciting and interesting competition.
Keeping Customers Operational
@YellowsBestLtd continues with our aim of Keeping Customers Operational by seeking out new products and legacy equipment spares to maintain new and well-established networks. Recent enquiries have been fulfilled supplying refurbished and surplus stocks of equipment cards, as well as built-to-order cables and connectors to suit exact requirements.
We would welcome any enquiries for the supply of similar or alternative parts, or support services to provide hardware repairs. Please get in touch; we look forward to hearing from you!
Continuing in Operation, Still Available for Supply
The ‘Dynanet’ product family is a range of PDH telecommunications products first launched by Nokia over 20 years ago. This equipment has proven to be incredibly reliable and dependable, extensively deployed by Operators, Utilities and Transport companies to provide resilient and highly available transmission networks.
A continuing challenge for public and private network owners is the ongoing maintenance of infrastructure systems to support their business needs. In many cases, it makes sense to continue to operate legacy systems which are still fulfilling unchanged requirements, rather than contemplate costly and time-consuming change-outs and replacements.

Public Safety, Utility and Transport organisations over many years have deployed Private Mobile Radio (PMR) infrastructure equipment with high availability and reliability to provide to provide dedicated, secure communications networks.
Modern implementations of PMR utilise the digital TETRA standard, which provides interoperability between systems and terminals from a range of manufacturers.
@YellowsBestLtd our mission is “Keeping Customers Operational”, by continuing to provided spares solutions, hardware repairs and support services to ensure continued long-term operations and maintenance.

Organisations that deploy, own and maintain infrastructure systems and networks make considerable investments in time and money, and it makes complete business sense to maximise the return on these investments. Even if it were desirable to make wholesale replacements, such projects take time to undertake. Ideally, if the equipment is performing satisfactorily and operational requirements have not changed, then is better to keep the existing equipment maintained for as long as possible.
Critical infrastructure systems are typically built to last, with high availability and reliable system components, and interchangeable spare parts. But sooner or later, repairs to elements are needed. During initial deployment and warranty periods, this is not normally an issue, but over time, these services become more specialised and difficult to obtain, as vendors advance their portfolios and discontinue older products.
@YellowsBestLtd specialises in ‘Keeping Customers Operational‘ by sourcing equipment spare parts and hardware repairs to modern and legacy systems. Should you have any requirements, please get in touch; we would be very pleased to hear from you, and look forward to being of assistance.

Many business operations depend on the security delivered by professional standard CCTV cameras, offering reliability, availability and a wide range of advanced features for mission-critical surveillance applications. One manufacturer that provides an extensive range of such products is Bosch; one of their latest models we feature here.
This example of a robust PTZ IP camera is suitable for deployment in extreme outdoor locations that require reliable 24-hour security monitoring. It features a range of advanced imaging technologies as well as Bosch’s Intelligent Video Analytics.
Featuring a 1/2″ 2MP CMOS sensor and a 6.6-198mm motorized zoom lens, the camera captures video at resolutions up to 1920 x 1080 at 60 fps in a 58.3 to 2.1° field of view. The camera delivers color video in lighting conditions as low as 0.0047 lux and uses an automatic IR cut filter to switch from color to B&W for day/night functionality.
An integrated high-speed pan/tilt system with an anti-backlash drivetrain provides 360° continuous panning and 290° tilting at up to 120° and 90° per second, respectively. Housed in an IP68- and IK10-rated enclosure and equipped with a window defroster, the camera is suitable for use in vandal-prone outdoor locations. Audio input and output ports allow for two-way talk while an SD card slot enables onboard storage of footage. ONVIF compliance ensures compatibility with a wide range of surveillance devices.
