Key Features
- 5MP Resolution at 2592 × 1944: At full 5MP (4:3), you get roughly 2.5× the pixel count of 1080p — enough to identify faces and read badge numbers at distances that would leave a 2MP camera guessing. The sensor also outputs 3.8MP in 16:9 for widescreen VMS layouts without cropping the scene.
- 3.3–10.2mm Varifocal Lens (101° to 30° HFOV): The 3.1× zoom range lets one SKU cover everything from a wide lobby entrance (101° HFOV) to a focused corridor or doorway (30° HFOV). That flexibility cuts SKU count on multi-room government projects where wall-to-wall fixed lenses would require three or four different models.
- 120 dB Dynamic Range: Scenes with simultaneous bright windows and shadowed interiors — think lobby entry vestibules, server room glass walls, or courtroom perimeter doors — stay usable in both zones at once. This is a meaningful spec advantage over cameras capped at 90–100 dB WDR when you're dealing with high-contrast government building facades.
- IVA Pro Buildings Analytics (Person + Vehicle): On-board intelligent video analysis runs directly on the camera's 2 GB RAM / 8 GB flash platform, classifying persons and vehicles with filters for duration, size, aspect ratio, direction, and color. That means rule-based alerts without a separate analytics server — useful for unmanned federal entry points or after-hours perimeter monitoring where edge detection reduces network load on the NVR.
- H.265 Compression: H.265 reduces storage and bandwidth roughly 40–50% compared to H.264 for equivalent quality — directly relevant when recording 5MP streams 24/7 across dozens of channels. On a multi-camera government deployment, the codec choice alone can cut recorder storage requirements in half. MJPEG is also available for VMS workflows that require it.
- IEEE 802.3af / 802.3at Class 3 PoE (2.4–3.4W): Drawing only 2.4–3.4W, this camera sits well within standard 802.3af budgets — your existing PoE switch won't need upgrading, and per-port power headroom stays comfortable even on fully loaded 24-port switches. No separate power supply run needed.
- IK10 Impact Rating: IK10 is the top of the IEC 62262 impact scale, rated to withstand a 20-joule strike — equivalent to a 5 kg mass dropped from 400mm. For government lobbies, detention facilities, or any space with elevated vandalism risk, this rating provides real physical deterrence without needing an external housing.
- Micro SD / SDHC / SDXC Up to 2 TB + 5-Second Pre-Alarm Buffer: Local storage to 2 TB provides a meaningful on-camera redundancy layer when network connectivity is interrupted. The 5-second pre-alarm buffer captures the event lead-up — critical for incident review when the triggering action precedes the alert by a few seconds.
- End-to-End Encryption + RSA 4096 / AES-256 / xTS-AES: The camera supports full end-to-end encryption with compatible VMS platforms, RSA 4096-bit key exchange, AES/CBC 256-bit stream encryption, local storage encrypted via xTS-AES, and x.509 PKI certificate support. For government IT security officers, this is the spec sheet that satisfies a cybersecurity review — video authentication via MD5/SHA-1/SHA-256 further supports chain-of-custody requirements.
- -40°C to 60°C Operating Range: The operating temperature envelope covers the full range of unconditioned mechanical spaces — electrical rooms, covered exterior alcoves, and unheated utility corridors — without additional thermal housing.
- Privacy Masks (8 configurable): Eight independently configurable privacy masks handle HIPAA, FERPA, or facility-specific compliance zones (restroom adjacent areas, private offices) within a single camera's view — no extra software license required.
Integration and Compatibility
The NDI-3703-A-GOV conforms to ONVIF Profiles S, G, M, and T — the broadest conformance set in this class. Profile G covers on-camera storage management through the VMS; Profile T adds H.265 and metadata streaming for analytics integration. Any VMS with ONVIF Profile T support can ingest both the video stream and IVA Pro metadata simultaneously, enabling server-side alerting without a dedicated analytics module. The 10/100BASE-T Ethernet interface is standard; Gigabit is not required. Pan range of 355°, tilt to 85°, and 355° roll adjustment on the dome head make physical alignment straightforward during commissioning, including ceiling-to-wall transitions. For network video recorders, the camera's native H.265 and ONVIF Profile G storage support enables direct on-VMS management of the local SD card buffer.
Plan your PoE switch infrastructure alongside this camera using a PoE switch — at 2.4–3.4W per port, even a 150W budget switch handles 40+ of these cameras simultaneously.

Frequently Asked Questions
Q: What ONVIF profiles does the NDI-3703-A-GOV support?
A: The NDI-3703-A-GOV is ONVIF conformant to Profiles S, G, M, and T. Profile T is the current generation profile that adds H.265 streaming and rich metadata, while Profile G supports on-camera storage integration through a compatible VMS.
Q: How much power does the NDI-3703-A-GOV draw, and what PoE standard does it require?
A: The camera draws 2.4–3.4W and operates on IEEE 802.3af (Class 3) — standard PoE available on virtually every current managed PoE switch. It is also compatible with 802.3at (PoE+). No mid-span injector or upgraded switch is required if your existing infrastructure is 802.3af-capable.
Q: Can the NDI-3703-A-GOV store video locally if the network goes down?
A: Yes. The camera includes a Micro SD/SDHC/SDXC slot supporting up to 2 TB of local storage, plus a 5-second pre-alarm recording buffer held in internal memory. Local storage encryption via xTS-AES is supported, which is relevant for government and regulated-facility deployments.
Q: What analytics are available on the NDI-3703-A-GOV without a separate server license?
A: IVA Pro Buildings runs on-camera and classifies persons and vehicles as object classes. Filters include duration, size, aspect ratio, direction, and color — all processed at the edge on the camera's 2 GB RAM platform with no external analytics server required.
Q: What is the dynamic range of the NDI-3703-A-GOV, and where does it matter?
A: The camera delivers 120 dB of dynamic range. This is the spec to review for scenes with simultaneous bright and dark zones — lobby entries with exterior glass, covered parking transitions, or server room viewing corridors. At 120 dB, both the bright and shadow zones of the same frame remain detail-usable rather than blown out or crushed.
Q: What cybersecurity features does the NDI-3703-A-GOV include?
A: The camera supports RSA 4096-bit key exchange, AES/CBC 256-bit stream encryption, xTS-AES local storage encryption, x.509 PKI certificate authentication, and video stream authentication via MD5, SHA-1, and SHA-256 checksums. Full end-to-end encryption is supported with compatible VMS platforms. These are the specifications typically reviewed during a government or enterprise IT security assessment.
The NDI-3703-A-GOV is the model I'd spec for government facility interiors where both cybersecurity compliance and edge analytics are hard requirements. The combination of RSA 4096 / AES-256 encryption with IVA Pro Buildings running on 2 GB of on-camera RAM is the pairing that gets this past an IT security officer and a physical security director in the same meeting — without adding server-side analytics licenses to the project budget.
Technical Highlights:
- 120 dB Dynamic Range: At 120 dB, this camera handles the worst lobby and entry vestibule lighting I've seen — direct sunlight through glass doors simultaneously with deep shadow interiors — and both zones remain forensically usable in a single frame. Most mid-tier domes cap at 90–100 dB; that 20–30 dB gap is visible in evidence-review footage.
- IVA Pro Buildings at the Edge: Person and vehicle classification with direction, color, and size filters runs entirely on the camera's 2 GB RAM / 8 GB flash platform. For unmanned government entry points or after-hours monitoring, that means rule-based alerts without a dedicated analytics server consuming rack space and licensing budget.
- 2.4–3.4W PoE Class 3: This is genuinely low draw for a 5MP analytics camera. On a 150W 24-port switch, you can run 40+ of these without exceeding the power budget — which simplifies infrastructure planning on larger multi-wing facility projects considerably.
Deployment Considerations:
- The varifocal range of 3.3–10.2mm covers 101° down to 30° HFOV — set the lens during commissioning to match the specific room geometry rather than defaulting to wide; the IVA Pro analytics classification accuracy improves meaningfully when the subject occupies more of the frame.
- End-to-end encryption requires a compatible VMS — confirm your VMS version supports ONVIF Profile T and Bosch's encryption handshake before promising this feature to a government IT security officer during the design phase. Profile T conformance is confirmed; VMS-side support varies by vendor and version.
This camera fits best in federal building lobbies, controlled-access corridors, and courtroom perimeter coverage — anywhere the combination of IK10 physical hardening, on-board analytics, and documented encryption capability all show up on the acceptance checklist simultaneously. The NDI-3703-A-GOV (often searched as NDI 3703 A GOV) covers that intersection cleanly within a standard PoE budget.
