Axis Q6135-LE storage & retention (2MP, H.265)

The Q6135-LE's 2MP sensor streamed at a typical 6 Mbps in H.265 is the figure that drives every downstream number here, and it lands at roughly 65 GB per camera per day of continuous recording. H.265's smart-codec compression is doing real work in that figure: at the same 2MP resolution and frame rate, plain H.264 typically pushes noticeably more bits per second for a comparable picture, so the per-camera daily footprint would be higher without it. The 65 GB/day baseline in this preset already reflects the H.265 encode.

Scaling from one camera to a fleet is linear: 16 cameras times 30 days of continuous recording works out to roughly 31 TB of usable storage. Add cameras or extend retention and the total moves in step - double the cameras or double the days and storage roughly doubles too. At 16 cameras, the resulting head-end still falls within the Entry NVR class; larger counts or longer retention windows push the architecture into higher tiers.

Use the calculator's controls to see this move in real time: drag the camera-count slider, change the retention-day setting, or switch the recording schedule and watch the storage total recompute immediately. Switching from an always-on schedule to a motion-only one applies a duty-cycle factor that reduces the effective recording hours per day, which can meaningfully cut the storage total for scenes with long quiet periods.

The calculator will not tell you the real bitrate variance a Q6135-LE produces on a busy versus a quiet scene, since 6 Mbps is a typical average and actual footage varies with motion, lighting and compression complexity. It also does not account for RAID or redundancy overhead, any separate failover or long-term archive tier, network write-bandwidth limits at the switch or NVR, or the exact drive make-up (count, capacity, RAID level) needed to physically house the total. Those remain engineering decisions for the specific site.
