Your Cameras Saw Everything — Your Recorder Forgot All of It
Here's a Kingston classic: something happens on the premises — a break-in, a delivery gone missing, a car clipped in the lot — and everyone turns to the CCTV system like a courtroom witness. The cameras were recording. The red light was on. And when you open the footage... corrupted files, missing hours, or a drive that now clicks like a maraca.
The cameras didn't fail. The recorder did, and the culprit is usually the same: power.
What a power cut does to a recorder
An NVR or DVR is a computer with a hard drive spinning inside it. When JPS drops the power mid-write, the drive's write head is interrupted mid-operation. Do that once and you might lose a file. Do it weekly — which is to say, do it as a Kingston business in outage season — and the drive degrades sector by sector until it either corrupts its index or dies outright.
Brownouts are sneakier. The lights don't fully go out, so nobody notices, but the voltage sag is enough to make drives and power supplies stutter. It's death by a thousand flickers.
The other way outages eat footage
Even when the recorder survives, the system goes dark during the outage itself. If your cameras, recorder, and network switch all die when the power does, you've bought a surveillance system that takes a break at the exact moment things get interesting.
The fix is boring and cheap
- A UPS on the recorder and switch. Not to run for hours — just long enough for clean shutdowns and to ride through the short cuts. Ten minutes of runtime covers most events.
- A surge-protected feed. Outage restoration is when the nastiest spikes arrive.
- Drives built for surveillance. Desktop hard drives are rated for office hours; surveillance drives are rated to write 24/7. They're not interchangeable.
- A weekly footage check. Not whether the cameras show a picture — whether playback works. Finding out the footage is gone during the incident review is the worst possible QA process.
How we approach it
Innovera designs surveillance systems for Jamaican conditions — which means power conditioning and backup are part of the spec, not an afterthought. If your footage keeps "going missing," — the diagnosis is usually quick.
