Evidence or Impressionist Art? Why Most Kingston Robbery Footage Is Useless
Every shopkeeper's nightmare isn't the break-in — it's the morning after, when you pull up the footage and discover that your four-camera system has produced an abstract painting. There's a figure, possibly human, definitely blurry, moving through a scene lit like a moody music video. The police ask if you have a face. You have a shape.
This isn't bad luck. It's a specification problem, and it was baked in at purchase.
The four ways footage becomes unusable
1. The wide-shot trap. One camera covering the whole yard feels efficient. It's also a pixel budget blown on scenery — the intruder gets maybe 40 pixels of face. At identification distances you need pixels on the subject, which means narrower views at the choke points.
2. The resolution that isn't. The camera says 4K on the box, but the recorder is compressing it to save drive space, the bitrate was set to "economy" during install, and the result is 4K-shaped mush. Resolution on the spec sheet and resolution on the evidence are different things.
3. Kingston's glare. A camera facing a bright storefront or a sunlit gate without WDR (wide dynamic range) renders the visitor as a silhouette in a white explosion. Our sun is not a minor character in this story.
4. Frame rate starvation. Setting 8 frames per second to stretch storage produces a slideshow — the moment a hand crosses the counter happens between frames.
What evidence-grade actually requires
- Enough pixels on target: the rule of thumb is ~250 pixels per metre at the identification point
- WDR on any camera facing bright outdoors, glass, or headlights
- Storage and bitrate set for evidence, not economy
- At least one camera per entry at face height (see: the tops-of-hats problem)
- Playback tested monthly, not discovered during the incident
How we approach it
Innovera designs surveillance around the question "will this hold up when it matters?" — camera selection, lensing, WDR, bitrate and retention set deliberately for Jamaican lighting and evidence standards. If your current system produces abstract art, .
