Which industry accreditations do you hold?
In the UK, reputable firms usually carry NSI Gold or SSAIB certification. These schemes audit everything from staff vetting to tool calibration. Anyone can buy cameras; accreditation proves they follow recognised standards such as BS EN 62676.
You can check certificates on the SSAIB public directory for peace of mind.

Do you design with open standards like ONVIF and OSDP?
Open standards prevent vendor lock-in. If the installer promises a “closed ecosystem” that only they can service, think twice. ONVIF Profile T lets any compatible recorder talk to any compliant camera; OSDP secures card-reader data in integrated systems.

How do you handle cyber-security?
Default passwords, unencrypted logins and open ports are a burglar’s best friend. A competent installer should mention HTTPS, VLAN segregation, regular firmware updates and written patch schedules. If they look puzzled, move on.
