Annual service (member rate)
Q: How often should an intercom system be serviced in South Africa?
Intercom systems should be serviced annually. Service includes speaker and microphone test, video camera lens clean, power supply voltage measurement, cable and connection inspection, and gate release relay test. In coastal areas like Cape Town and Durban, salt air accelerates speaker diaphragm corrosion and connector oxidation — making annual service particularly important.
What the annual intercom service covers
✓Speaker and microphone test — audio clarity measured; corroded diaphragms cause muffled or no audio
✓Video camera clean and check — lens cleaned; night vision IR LEDs tested; image quality verified
✓Power supply voltage test — transformer output and supply voltage verified to specification
✓Cable and connection inspection — SANS 10142 compliant; cable condition, gland seals, connector corrosion checked
✓Gate release relay test — relay contacts tested; corroded contacts are the most common cause of gate not releasing remotely
✓Housing seal inspection — outdoor unit weather seals checked; moisture ingress destroys circuit boards
✓Indoor unit test — all indoor handsets tested for full functionality

Frequently asked questions
What brands does HomeGuard Pro service?+
All major SA brands: Kocom, Samsung, Commax, Urmet, Golmar, and generic audio intercom systems. Video and audio both covered.
My intercom crackles — is that a service issue?+
Yes. Crackling is typically a corroded speaker connector or deteriorating cable. Left unattended, it progresses to complete audio failure.
Can a failed intercom be repaired or replaced?+
Most failures are at connector or speaker level — both repairable at low cost. Complete board failure from moisture typically requires unit replacement. Your technician diagnoses and quotes before any work proceeds.
