Planned update:
Have a question now? Contact our teamShould we choose an on-premises server or a cloud-based system?
Choose around your IT policy, data location, remote access needs and available IT resources. On-premises puts infrastructure under your organisation’s management; cloud reduces the need to maintain a local application server. We review both options against your requirements.
When is an on-premises solution the better choice?
It may suit organisations with an established IT team, internal hosting requirements or restricted internet access. Agree responsibility for backups, updates, availability and remote access before choosing this architecture.
When is a cloud-based solution the better choice?
Cloud can suit organisations seeking centrally managed software and access across several sites without maintaining a local application server. Check connectivity, data location, retention, subscription terms and the provider’s backup arrangements.
Does an on-premises system need a dedicated physical server?
Not necessarily. A supported virtual server may be suitable, depending on the selected platform. Your IT team should confirm operating system, resources, backup, security and availability requirements before installation.
How do sensors and data loggers communicate?
Depending on the system, devices use Ethernet, Wi-Fi or dedicated radio communication such as LoRa-based technology. Wireless devices typically send readings through a gateway or access point, which connects to the server or cloud platform. Technologies and devices are not automatically interchangeable.
Do all wireless loggers use our Wi-Fi network?
No. Some use a dedicated radio network and a gateway connected to your IT network. Others connect directly to Wi-Fi. The choice depends on coverage, IT policy, battery requirements and the selected equipment.
Will the wireless signal reach through walls or into freezers?
Coverage depends on building materials, metal enclosures, equipment position and interference. We assess the proposed locations and verify communication on site. External probes can allow the logger to remain outside a freezer while measuring inside it.
What happens if the internet or network connection fails?
Loggers with local memory can continue recording within their storage capacity and configured operating conditions. Uploading, dashboards and remote alerts may be interrupted. Recovery and backfilling depend on the system, so outage behaviour should be specified and tested.
What happens during a power failure?
Battery-powered loggers can continue measuring while their batteries last. Gateways, network equipment and servers may need UPS protection. If power-loss detection is required, it should be included explicitly in the design and alarm tests.
Which parameters can we monitor?
Depending on the selected sensors and interfaces, a solution can cover temperature, humidity, differential pressure, CO₂, oxygen depletion, liquid nitrogen level, airborne particles, door status, power loss and 4–20 mA signals. Each parameter requires suitable equipment and an agreed measurement range.
Can one system cover several departments or sites?
A suitable platform can centralise multiple locations with separate access permissions and alarm recipients. We define the sites, expected expansion, connectivity and licensing requirements before selecting the architecture.
How often should readings be recorded?
The interval should reflect process risk, how quickly conditions can change and the required evidence. Recording, transmission and dashboard refresh intervals may differ. We agree each separately and check the selected equipment supports them.
How are alarms delivered?
Depending on the platform and configured services, alerts can be sent by email, SMS, voice call or other supported channels. Delivery relies on the relevant network and notification service. We agree recipients, channels and test scenarios before handover.
Can an unanswered alarm escalate to another person?
Where supported, escalation rules notify additional recipients if an alarm is not acknowledged within an agreed time. We define responsibilities, schedules and escalation steps, then test them with your team.
Can we avoid unnecessary alarms when a door is opened?
Suitable systems allow alarm delays and other configurable conditions. These should be based on permitted excursions and process risk, rather than simply suppressing notifications. Door status can provide useful context where an appropriate input is available.
Can different staff have different permissions?
Platforms with role-based access can separate viewing, alarm acknowledgement, configuration and administration. We agree the required roles and account policy with your organisation. Available controls depend on the selected software.
What is an audit trail and why does it matter?
An audit trail records relevant actions and changes with their timing and user identity. It supports traceability and review of electronic records. The recorded events, retention and review procedure should be checked against your requirements.
Does the system support GxP and 21 CFR Part 11 requirements?
We can select systems with features that support applicable requirements, including access controls, audit trails and record protection. Compliance also depends on validated intended use, configuration, procedures and staff practices. Software features alone do not establish compliance.
How often do sensors need calibration or verification?
The interval depends on the instrument, application, manufacturer guidance, risk assessment and applicable requirements. We agree calibration points, acceptance criteria and the procedure for replacing or checking sensors without leaving critical locations unmonitored.
What information do you need to prepare a proposal?
Send the rooms or equipment to monitor, parameters and ranges, point count, alarm needs, preferred hosting model and IT restrictions. Include any URS, drawings, retention requirements and qualification needs. We can help turn these into an agreed scope.
Qualification and validation
5 questionsWhat do URS, IQ, OQ and PQ mean?
URS defines user requirements. IQ verifies installation against the approved design and requirements. OQ verifies operation across specified conditions. PQ demonstrates performance under agreed conditions representative of intended use.
Do we need every qualification stage?
The scope depends on intended use, risk, applicable requirements and existing evidence. We agree the required stages, any design review and justified use of supplier documentation before testing.
Is temperature mapping the same as qualification?
Mapping assesses temperature distribution across a defined space and test scenario. It can form part of qualification, but does not replace all installation, operational or performance checks.
How long will mapping or qualification take?
Duration follows the agreed protocol, operating cycles, loading conditions and risks. There is no single duration for every application. Door-opening, recovery and other challenge tests are included where relevant.
What documents will we receive?
Deliverables are agreed in advance and may include the URS, approved protocols, calibration evidence, test records, deviations and a final report. Acceptance criteria and responsibility for review and approval should be clear before work begins.
Technical service and maintenance
5 questionsWhat is the difference between maintenance and repair?
Preventive maintenance is planned work intended to keep equipment operating reliably. Repair addresses a fault. The work and parts required depend on the equipment condition, manufacturer guidance and agreed scope.
How often should equipment be serviced?
Follow the manufacturer’s recommendations and applicable requirements, taking account of use, condition and your maintenance programme. We help define an appropriate schedule for the specified equipment.
What information should we send about a fault?
Include the manufacturer, model, serial number, location, error message and a description of what happened. Photos and service history can help assess the next step. Follow your site’s procedures if the equipment may be unsafe to use.
Can the work be completed at our site?
This depends on the model, required tests, parts and working conditions. We confirm whether an on-site visit or workshop assessment is appropriate before scheduling the work.
Do you provide training and service records?
User instruction and documented service records can be included in the agreed scope. We confirm the training content, checks performed and records supplied for each job.
Equipment and distribution
4 questionsCan you help us select suitable equipment?
Yes. Start with the intended application, required performance, operating environment and available space. We review suitable options against your specification and budget.
Can you work from our technical specification?
Yes. Share the specification or URS and highlight mandatory requirements. We clarify ambiguities and assess the proposed configuration before preparing an offer.
Can installation and training be included?
They can be included where applicable. We define delivery, installation, commissioning, training and any qualification work separately so the responsibilities are clear.
How are delivery times and warranties confirmed?
We confirm lead times and warranty terms for the specific product and offer. Timing can depend on stock, configuration and manufacturer availability. The quotation sets out the agreed conditions.
