Common Issues & Quick Fixes

Field-tested solutions from our engineers — before you call us, try these first

Likely cause: DNS latency or Wi-Fi channel congestion.

Fix: (1) Change your DNS to 8.8.8.8 / 1.1.1.1 in network settings. (2) Log into your router and switch the Wi-Fi channel from Auto to a fixed one — try Channel 1, 6, or 11 for 2.4 GHz. (3) If your router is older than 3 years, the firmware may be throttling speeds — check for updates in the admin panel.
Likely cause: Hard drive failure or loose SATA connection.

Fix: (1) Power cycle the DVR/NVR — a full shutdown and restart clears false HDD errors in 30% of cases. (2) Check Storage > HDD in the DVR menu — if it shows "Uninitialized", initialise the drive from within the menu (this wipes footage). (3) If it shows "Error" after restart, the drive needs replacement — typically a surveillance-grade SATA drive (WD Purple or Seagate SkyHawk series). Do not use desktop drives in CCTV systems.
Likely cause: Failing HDD, misconfigured SMB settings, or a duplex mismatch on the network port.

Fix: (1) Run SMART diagnostics — in Windows Server, open CrystalDiskInfo or run wmic diskdrive get status. A "Caution" or "Bad" result means the drive is failing. (2) Check Task Manager > Performance > Disk — if it shows 100% disk usage, something is hammering the drive in the background (often Windows Search indexing). (3) Check the NIC is set to 1 Gbps Full Duplex, not Auto, in Device Manager.
Likely cause: Bad patch cable, port disabled in config, or a blown PoE port.

Fix: (1) Swap the patch cable first — a crimped cable accounts for 60% of single-port failures. (2) Try the device in a known-working port to rule out the end device. (3) If using a managed switch, check if the port was administratively disabled — look in the switch's port management section. (4) For PoE ports, if the connected device is drawing more power than the port budget allows, the port shuts itself off — check PoE budget in the switch dashboard.
Likely cause: DNS failure, IP conflict, or ISP line issue.

Fix: (1) Open Command Prompt and run ipconfig /release then ipconfig /renew to get a fresh IP. (2) Run ping 8.8.8.8 — if this works but websites don't, it's a DNS issue. Run ipconfig /flushdns. (3) If ping fails too, check if other devices have the same issue — if yes, the problem is the ISP line or the router, not the laptop. Restart the router and modem.

CCTV Storage Guide

Approximate storage for 1 camera, continuous 24h recording:

Resolution Per Day 30 Days
1 MP (720p)~7 GB~210 GB
2 MP (1080p)~14 GB~420 GB
4 MP~28 GB~840 GB
8 MP (4K)~56 GB~1.7 TB

*Motion-triggered recording reduces storage by 40–60%.
