Calculate exact equipment specifications before booking an install. Use our trade diagnostic calculators below to find the correct CCTV camera lens for face identification, calculate NVR hard drive storage, plan outbuilding Wi-Fi bridges through solid stone, or check TV fireplace heat safety.
Instant database of 358+ television models across Samsung, LG, Sony, Hisense & TCL. Calculate exact VESA patterns, bolt specifications (M4/M6/M8), wall substrate fixings (Dot & Dab, Drywall, Masonry), and eye-level viewing height in 30 seconds.
Plan perimeter coverage, 10ft mounting heights, and calculate exact 30-day NVR hard drive storage (TB) across 1080p, 4MP, and 4K cameras.
Interactive 5-step troubleshooting tool for No Signal errors, picture pixelation, missing Freeview channels, loft amplifier faults, and FM/DAB radio issues.
Calculates the exact focal length (2.8mm to 12mm) needed for police-evidentiary facial identification (250 px/m) vs Recognition (125 px/m). Prevents wide-angle smear on long drives.
Calculates exact hard drive storage capacity required for 30-day continuous recording across 4K, 5MP, and 1080p cameras, comparing H.265+ smart codecs to standard compression.
Calculates 60GHz wireless link speeds, Fresnel zone clearance, and compares 20m–100m trenching costs against point-to-point wireless bridges for outbuildings and garden offices.
Evaluates external black UV Cat6 routing, internal stud drops, and MoCA coax adapters. Solves thick plaster and carpet disruption with zero mess.
Calculates aerodynamic drag force in Newtons on Gen 3 and Mini flat panels. Verifies whether a chimney lashing cradle or heavy-duty wall bracket is required for your exposed ridge.
Compares hardware purchase, monthly tariffs, expected weather latency, and 24-month total cost of ownership between Starlink satellite and external 4G/5G mast antennas.
Calculates mantelpiece heat deflection and safe mounting heights above log burners, gas fires, and open grates. Prevents OLED panel delamination and premature motherboard failure.
Calculates vertical drop distance, viewing angles, and neck strain angles from sofa distances of 2m to 5m, determining whether a mechanical drop-down mount is required.
Aggregates power draw across PTZ heaters, ColorVu warm lights, and Wi-Fi 7 access points. Prevents intermittent camera rebooting caused by power supply budget shortfalls.
Calculates electrical resistance over 20m to 100m cable runs. Demonstrates why copper-clad aluminium (CCA) drops below 44V minimum threshold and burns out switch ports.
Diagnoses whether existing UK consumer chime wiring has sufficient voltage (16V–24V AC at 30VA) for Ring, Nest, or Eufy video doorbells, preventing chime hum and battery drain.
In-depth technical guides addressing real homeowner struggles across the UK, with interactive calculators embedded directly into the solutions.
Why standard 2.8mm wide-angle lenses fail beyond 4 metres and what focal length is required for police-evidentiary facial identification at 10m or 15m.
Discover why powerline plugs fail across split RCD consumer units, and how external solid copper Cat6 drops or MoCA 2.5 coax adapters deliver full Gigabit speeds with zero mess.
While these calculators provide reliable trade estimates, physical site conditions often require hands-on adjustments: reflective white rendered walls causing IR glare, 2-foot Yorkshire gritstone attenuating radio frequencies, or high-level chimney stacks requiring non-drill lashing cradles.
