# Frigate NVR & CCTV Setup
**Last Updated:** May 2026
**Host:** jgpc — `192.168.88.41`
---
## Hardware
| Component | Details |
|-----------|---------|
| Machine | Lenovo jgpc P710 |
| CPU | Intel Xeon E5-2623 v4 @ 2.60 GHz (4 cores / 8 threads, boost to 3.2 GHz) |
| RAM | 24 GB |
| GPU | NVIDIA GeForce GTX 1050 Ti (4 GB VRAM) |
| OS Disk | 234 GB SSD (`/dev/sda2`) |
| Media Storage | 14 TB HDD — mounted at `/mnt/14TB-HD/frigate/media` |
---
## Frigate Docker Setup
| Item | Value |
|------|-------|
| Image | `ghcr.io/blakeblackshear/frigate:stable-tensorrt` |
| Container name | `frigate` |
| Config path | `/srv/docker/frigate/config/` |
| Media path | `/mnt/14TB-HD/frigate/media` |
| Compose file | `jgpc/frigate/docker-compose.yml` (this repo) |
| Web UI | `http://192.168.88.41:5000` → `https://cameras.jgitta.com` |
| RTSP port | `8554` |
| WebRTC port | `8555` |
**GPU acceleration:** Container runs with `runtime: nvidia` and `NVIDIA_VISIBLE_DEVICES=all`. The GTX 1050 Ti handles:
- LPR (licence plate recognition) via GPU
- Birdseye re-stream encoding via `h264_nvenc`
- ONNX object detection via the `onnx` detector
**Shared memory:** `shm_size: 1024mb` — required for frame buffers across 6 cameras.

## Camera Inventory
All cameras are **Reolink** PoE units on the `192.168.88.0/24` subnet.
| Camera | IP | Model notes | Mount location |
|--------|----|-------------|----------------|
| front_driveway | 192.168.88.105 | Dual-lens panoramic (7680×2160 = two 4K sensors stitched) | Front driveway |
| front_yard | 192.168.88.104 | 4K 811A | Front yard |
| shop | 192.168.88.103 | 4K 811A (uses HTTPS for API) | Shop / outbuilding |
| deck | 192.168.88.101 | 4K 811A | Deck |
| back_yard | 192.168.88.102 | 4K 811A | Back yard |
| front_right | 192.168.88.100 | 4512×2512 sensor (non-standard resolution) | Front right |
---
## Camera Stream Settings
All cameras confirmed via Reolink API (May 2026):
| Camera | Main Resolution | Main Codec | Bitrate | FPS | I-frame | Sub Resolution | Sub Codec |
|--------|----------------|------------|---------|-----|---------|----------------|-----------|
| front_driveway (.105) | 7680×2160 | H.265 | 10240 Kbps | 20 | 1x | 1536×432 | H.264 |
| front_yard (.104) | 3840×2160 | H.265 | 6144 Kbps | 25 | 1x | 640×360 | H.264 |
| shop (.103) | 3840×2160 | H.265 | 6144 Kbps | 25 | 1x | 640×360 | H.264 |
| deck (.101) | 3840×2160 | H.265 | 6144 Kbps | 25 | 1x | 640×360 | H.264 |
| back_yard (.102) | 3840×2160 | H.265 | 6144 Kbps | 25 | 1x | 640×360 | H.264 |
| front_right (.100) | 4512×2512 | H.265 | 8192 Kbps | 20 | 1x | 896×512 | H.264 |
**I-frame interval** set to 1x on all cameras so Frigate can start/end recording clips cleanly without waiting for a keyframe.

## go2rtc Stream Architecture
Chrome/Firefox cannot play H.265 (HEVC) via MSE (Media Source Extensions), so each camera requires two go2rtc streams:
```
camera_h265 → native H.265 RTSP from camera
└─ consumed by Frigate ffmpeg for RECORDING (stream copy, no re-encode)
camera → ffmpeg:camera_h265#video=h264 (software H.265 → H.264 transcode)
└─ served to browser via MSE WebSocket for LIVE VIEW
camera_sub → native low-res H.264 RTSP sub-stream
└─ consumed by Frigate for OBJECT DETECTION only
```
**Key behaviour notes:**
- go2rtc uses **lazy initialization** — transcoders only start when a browser opens the live view, and shut down ~30 seconds after the last viewer leaves. This causes a 2–3 second gray screen on first view, which is expected and unavoidable.
- The `_h265` streams are kept alive continuously by Frigate's recording ffmpeg processes, so recording starts instantly.
- The `#hardware` flag for NVENC transcoding in go2rtc causes EOF crashes with Reolink cameras and **must not be used**. Software transcoding (`libx264`) is used instead.
- Reolink cameras drop RTSP connections every 5–20 minutes (firmware behaviour). go2rtc reconnects automatically; this produces a brief gray screen, not static.
### shop camera note
The shop camera (`192.168.88.103`) redirects HTTP → HTTPS. All API calls to shop must use `https://` with `-k` (skip cert verification).

## Frigate Camera Detection Zones
| Camera | Detect Resolution | Tracked Objects | Notes |
|--------|------------------|-----------------|-------|
| front_driveway | 1536×432 | person, car, dog, cat, license_plate | Has zone + LPR; alerts require `front_driveway_zone` |
| front_yard | 640×360 | person, car, dog, cat | — |
| shop | 640×360 | person, car, dog, cat | Motion mask on upper-right and mid-frame |
| deck | 640×360 | person, car, dog, cat | Two motion masks |
| back_yard | 640×360 | person, car, dog, cat | Two motion masks |
| front_right | 896×512 | person, car, dog, cat | Motion mask on upper-centre |
---
## Recording & Retention
| Type | Retention |
|------|-----------|
| Alert clips | 30 days |
| Detection clips | 30 days |
| Motion clips | 30 days |
| Continuous | Disabled |
| Snapshots | 30 days |

## Known Issues & Quirks
- **Reolink H.265 sub-stream firmware bug:** On some Reolink firmware versions, setting the sub-stream to H.265 produces a corrupted bitstream that go2rtc rejects with 404. Sub-streams should always remain H.264.
- **front_driveway panoramic:** The 7680×2160 resolution is two 4K sensors stitched side by side. The wide 1536×432 detect resolution in the Frigate config accounts for this.
- **front_right non-standard resolution:** Camera reports 4512×2512 rather than standard 4K. Model unknown — may be a 5MP variant or older sensor.
- **Swap pressure:** jgpc runs ~5.5 GB swap used under normal load. Monitor if adding more cameras or enabling Birdseye.
