FAQ
Site Assessment Questions
Are installation surveys and repair visits the same?
Submitting this enquiry costs nothing. A new-installation survey and a repair diagnostic visit are different. HJ confirms free-survey eligibility, any diagnostic or travel charges and the appointment before attendance.
How does the AI-assisted assessment work?
You send us your property details and, ideally, a few photos over WhatsApp. Our team uses AI-assisted analysis alongside our own installation experience to give you a fast preliminary read — likely camera count, coverage gaps, suitable system types — well before we ever step on site. It's a starting point, not a substitute for the in-person survey that finalises your actual system design and quote.
What should I send for a useful preliminary assessment?
Photos of your property's entry points, perimeter, and any areas you're specifically concerned about, plus a rough idea of the property size and which systems you're interested in. A simple floor plan or sketch helps too, but isn't required.
Does a preliminary assessment replace the site survey?
No — it's a fast, useful starting point so you know roughly what to expect before we visit. The in-person site survey is what finalises your exact system design, camera placement and quote, since photos can't fully capture things like cable routes, lighting conditions or building materials.

Survey, Repair & Outstation Visits
New installation & quotation
Site surveys for new installations are free. Send your requirements and HJ will arrange a convenient visit time.
Existing-system diagnosis & repair
A repair visit is different from a new-installation survey. Diagnostic attendance, labour and replacement parts are confirmed with you before work is authorised.
Outstation & travel
Share the exact site location. Travel charges, technician availability and the visit schedule are confirmed before attendance; listing a service area does not mean every visit is free.
