AI PTZ Dome — Dual-Use 3K
The cost-effective PTZ. 3K (3072 × 1728), 4× motorised zoom (2.8–12 mm), 20 m smart IR, 355° pan and 0–90° tilt — and the commercial story that matters: a PTZ camera at the cost of a fixed camera. The CA-1100 is the dual-use PTZ — operator-driven for control-room CCTV, AI-paired for precise scan-and-follow on difficult-to-aim installs. The custom NW-supplied aluminium housing fits it onto traffic-signal heads and standard lamp columns where a fixed camera would otherwise be the only option.
PTZ everywhere — not just where the premium budget reaches.
Traditional PTZs sit on dedicated masts at premium junctions — a small number of expensive cameras at the few sites where the cost is justified. The CA-1100 changes the math. At a price point close to the fixed bullets in this range, PTZ becomes specifiable on every traffic-signal head, every lamp column, every overhead bracket where a fixed camera was previously the only option. The custom NW aluminium housing handles the mount.
Two deployment patterns make the case:
Standalone operator mode. Control-room CCTV with active operators. The human drives the camera; the 4× zoom (90° → 25°), 355° pan and 0–90° tilt give a full hemispherical reach from a single mount. Town centres, critical-asset perimeters, event security.
AI-paired mode. Sit the CA-1100 alongside a wide-FoV AI bullet (CA-1010 or CA-1060). When SenseView detects an incident, the PTZ targets the location and zooms in automatically. The PTZ becomes the AI's investigation tool — and on a difficult mount, the same PTZ control lets the camera be precisely positioned remotely after install. No second cherry-picker visit.
F1.5, 0.005 lux colour, 20 m smart IR — competent across day-and-night conditions. For pure colour-at-night specialist work, the CA-1010 remains the answer. PoE 802.3af keeps the infrastructure simple.
A PTZ at the price of a fixed camera.
3K (3072 × 1728) at 25 fps PAL with a 4× motorised zoom (2.8–12 mm, F1.5). 20 m smart IR for night work. 355° pan, 0–90° tilt — near-full hemispherical coverage from one mount. 1/2.8″ progressive-scan CMOS with 0.005 lux colour minimum. PoE 802.3af (standard PoE, not PoE+) for straightforward infrastructure. Custom NW aluminium housing options for traffic-signal heads, standard lamp columns and overhead brackets.

What the hardware does.
Custom aluminium housing — signal heads, lamp columns, brackets
The CA-1100 alone is a competent compact PTZ. What changes the deployment case is the NW-supplied custom aluminium housing, designed to fit the camera onto highway infrastructure where conventional PTZ enclosures won't go. Standard housing options include traffic-signal heads, lamp columns and overhead brackets — keeping the visual profile slim, matching the colour and finish of existing street furniture, and meeting the structural / wind-load expectations of the host fitting.
The result: PTZ functionality available at the points councils already have power and infrastructure — not just at premium dedicated mast sites.
Housing model and finish specified per site by the NW design team. Compatible with standard 24 V DC and PoE 802.3af infrastructure already present at most signal-head and lamp-column sites.
355° pan, 0–90° tilt — full hemispherical reach
Continuous 355° pan (a small dead arc at the cable wrap), 0–90° tilt — from horizontal to straight down. A single CA-1100 covers a full hemisphere from one mount point, with a 5° gap directly behind. The operator can sweep an entire town square from a single corner install, or scan a critical-asset perimeter from one elevated mount.
Up to 256 preset positions, with auto-cruise and pattern-scan sequences. SenseView (Mode C) can drive the camera to detected event locations automatically — the AI bullet detects, the PTZ targets. Pan speed: up to 100°/s manual, 60°/s preset call.
The 4× optical zoom (2.8–12 mm) gives 90° wide for area scanning down to 25° narrow for face / plate / sign detail at the zoom limit.
3K imaging with 20 m IR for day-and-night work
3K (3072 × 1728) at 15 fps full-resolution PAL, stepping up to 25 fps at 1080p and below — well above 1080p, with pixel headroom for plate-readable zoom at the 12 mm narrow end. F1.5 aperture gives 0.005 lux colour minimum — competent in lit urban-night conditions, though for pure colour-at-night work the CA-1010 holds detail deeper into the dark. As the scene darkens further the camera switches to monochrome at 0.001 lux (visible spectrum, IR cut filter retracted, IR illuminator off); below that, the 20 m smart IR illuminator engages for 0 lux operation. Three light stages, one continuous transition.
120 dB true WDR keeps mixed-lighting scenes balanced. 3D digital noise reduction. IP66 and IK10 — fully weather-sealed and impact-rated for street-furniture installation.
The CA-1100 deploys in Mode A or Mode C.
The CA-1100 supports Mode A (capture & stream) and Mode C (video → AI box → SenseView). Mode B (on-camera AI events) is not the right deployment for an operator PTZ — a human in the loop is doing the cognition in Mode A, and a NOW Wireless AI box runs richer classification in Mode C than any on-camera processor could provide. Pick the deployment, not a workaround.
Capture & stream
The primary mode for operator-driven CCTV. Camera streams live 3K to a control-room or roadside NVR. Operators drive pan / tilt / zoom from the SenseView UI or any ONVIF console. 256 presets, auto-cruise, pattern-scan for unattended sweeps.
Smart events → SenseView
Not currently integrated with SenseView. The camera publishes on-camera smart events natively via ONVIF (line crossing, intrusion, region entry / exit, unattended object, object removal, face detection, audio exception). SenseView does not consume these from this model at present. For operator-driven PTZ use this is rarely the binding constraint — a human drives the camera in Mode A, and the AI box runs richer classification in Mode C. For low-bandwidth event-only sites where on-camera Mode B is essential, choose CA-1010, CA-1040, CA-1050 or CA-1060.
Video → AI box → SenseView
Full 3K stream to a NOW Wireless Nvidia AI box. The AI box runs vehicle / person / cyclist classification, plate enrolment, journey-time, DVLA cross-reference — and feeds SenseView. SenseView commands the PTZ to target detected events. Used for scan-and-follow workflows and precise remote commissioning on difficult installs.
What the AI platform adds.
The CA-1100 delivers a controllable 3K stream. SenseView turns the camera into either a fully operator-driven CCTV asset (Mode A) or an AI-targeted investigation tool (Mode C). Mode A and Mode C are both fully supported.
