Security cameras fail quietly. A spider web, a full hard drive, or an outdated firmware version can leave you with no usable footage on the one night you need it, and you will not find out until you go looking. A twice-yearly maintenance routine prevents nearly all of these silent failures. Here is the checklist we use on service visits across Houston.
Every Quarter: The 15-Minute Check
- Open your app and view every camera. Confirm each one shows a live, clear image.
- Pull up footage from three days ago on each channel. Recording that stopped weeks ago is the most common failure we find.
- Check the recorder for drive warnings or beeping.
- Verify motion alerts still reach your phone; a changed password or app update often breaks them silently.
Twice a Year: The Full Service
Lenses and Housings
- Wipe every lens and dome cover with a microfiber cloth. Houston humidity feeds a film of grime that softens night vision long before it is obvious by day.
- Clear spider webs and wasp nests from housings; webs reflect infrared light at night and trigger endless false motion alerts.
- Inspect seals and cable glands for cracking. A failed seal lets moisture into the connector, and corrosion follows within a season here.
Firmware and Software
- Update camera and NVR firmware. Updates patch security holes and fix recording bugs.
- Change default passwords if any device still has one. This is the single biggest security risk on older systems.
- Confirm the recorder clock is correct; a wrong timestamp can make footage useless as evidence.
Storage Health
- Check hard drive health in the NVR menu. Surveillance drives run 24/7 and typically last three to five years.
- Confirm your retention period is what you expect. Adding cameras shortens retention on the same drive.
- Replace any drive showing errors before it dies, not after.
Before Hurricane Season: The Houston Checklist
Do this every May, before storm season peaks.
- Tighten every mount and bracket; a camera that survives a storm loose will be aimed at the sky afterward.
- Trim branches near camera views and cable runs.
- Put the recorder and network gear on a UPS so cameras keep recording through power flickers.
- Export and back up any critical footage off-site in case of flooding.
- Test remote viewing from outside your network, since that is how you will check the property if you evacuate.
