Bosch NDI-3702-AL 2MP Indoor Dome Network Camera
Overview
The Bosch NDI-3702-AL is a 2MP wired network dome camera built for indoor and mixed-light surveillance where field-of-view flexibility and cost-effective 24/7 operation matter. The camera pairs a varifocal 3.3–10.2mm lens with integrated infrared illumination, letting you maintain usable images through day, dusk, and total darkness without adding auxiliary lights. It draws power and connectivity from a single PoE (802.3af) line — no separate power supply, no extra cabling runs. Support for H.265, H.264, and MJPEG compression gives you options: H.265 cuts storage overhead by roughly 50% compared to H.264 at the same quality, a meaningful factor when you're running 24/7 across multiple cameras. A built-in microphone enables audio capture for incident verification or two-way intercom workflows.
Key Features
- 2MP (1920×1200) Resolution: Adequate for identification and event documentation in medium-coverage areas — retail floors, office lobbies, warehouse entry points, corridors. Trades absolute detail for lower bandwidth and storage footprint. If you need closer facial detail at distance, consider a higher-megapixel IP camera variant in the same family.
- Varifocal 3.3–10.2mm Lens: Manual focal adjustment post-installation saves the cost and labor of lens swaps. Covers wide common-area views down to tighter entry-point framing, all within a single mount. No need to stock multiple lens types for different heights or distances.
- Integrated IR Day/Night: Built-in infrared illumination and automatic day/night switching eliminate reliance on ambient light or auxiliary floods. Operates in parking structures, unlit corridors, and storage areas where ambient light is scarce or absent. Removes a real installation constraint on fixture placement.
- H.265 (HEVC) Primary Codec: Supports H.265, H.264, and MJPEG. H.265 cuts data rate roughly in half versus H.264 at equivalent visual quality — on a 24/7 recorder with dozens of cameras, that translates to half the storage capacity needed or doubled retention time on the same drives. Bandwidth savings matter on congested networks or WAN-connected sites.
- PoE (802.3af) Power: Single twisted-pair delivery of power and data. Draws under 13W, so standard 802.3af PoE (15W available per port) supplies adequate headroom. No power supply, no conduit for separate AC lines, no wall outlets needed at the camera location. Simplifies rough-in and reduces point-of-failure dependencies.
- Built-in Microphone: Enables on-site audio recording for two-way intercom systems, incident verification, and compliance in access control lobbies or visitor areas. Audio integration with NVR or VMS systems requires local configuration of recording settings and microphone sensitivity.
- ONVIF Profile S Compliance: Works with Bosch Video Management Systems (BVMS), Milestone XProtect, and other enterprise VMS platforms. Standard RTSP/RTMP streams integrate with third-party encoders, automation, or custom integrations. No lock-in to a single ecosystem.
Integration and Compatibility
The NDI-3702-AL (often searched as NDI 3702 AL) connects to any standard PoE network switch or PoE injector. Confirm available PoE capacity on your switch — most modern managed switches allocate 15W per 802.3af port, leaving safe margin. Audio streams require configuration in the NVR or VMS to enable microphone input and set recording levels. For camera selection and deployment planning, balance the 2MP resolution against coverage distance; if subjects are 30+ feet away and facial ID is critical, spec a higher-megapixel model. Bosch cameras integrate cleanly with firmware updates and ONVIF discovery, reducing post-deployment surprises.
Typical Applications
Deploy the NDI-3702-AL in retail floors, office entry lobbies, education buildings, hospitality corridors, and light-industrial areas where discrete dome aesthetics matter and IR capability bridges variable lighting. The varifocal lens lets a single mount cover wide common areas or narrow entry doors without lens swaps. IR reach and microphone support fit access control turnstiles, reception zones, and inventory areas where audio verification adds compliance value. Compact form factor and low power draw mean minimal impact on architectural finishes.
Frequently Asked Questions
Q: Does the NDI-3702-AL support H.265 compression?
A: Yes. The camera supports H.265 (HEVC), H.264 (AVC), and MJPEG. H.265 is the primary codec and cuts bandwidth and storage roughly in half compared to H.264 at equivalent quality.
Q: What's the maximum power draw of the NDI-3702-AL?
A: The camera draws under 13W via standard PoE (802.3af). This leaves safe headroom on a 15W-per-port PoE switch.
Q: Is the NDI-3702-AL ONVIF compliant?
A: Yes. It supports ONVIF Profile S, enabling integration with Bosch BVMS, Milestone XProtect, and other enterprise VMS platforms.
Q: What is the infrared range of the NDI-3702-AL?
A: The camera includes integrated infrared illumination for day/night operation. Specific IR range depends on lens focus and scene reflectivity, but IR enables operation in dark or unlit environments.
Q: Can the NDI-3702-AL be used outdoors?
A: The NDI-3702-AL is designed for indoor and covered environments. If full outdoor exposure is required, consider a Bosch variant with higher IP ratings.
Q: Does the NDI-3702-AL include audio capabilities?
A: Yes. The camera has a built-in microphone input for on-site audio recording, two-way intercom integration, and incident verification workflows.

The Bosch NDI-3702-AL is a sensible pick for medium-density indoor surveillance where you want infrared capability, flexible framing, and straightforward PoE integration. The varifocal lens and 2MP resolution are straightforward tradeoffs: you avoid lens inventory and post-install swaps, but you don't get the detail density of a 4MP or 5MP sensor. The H.265 support is a real asset on constrained bandwidth or large multi-camera deployments.
Technical Highlights:
- H.265 Compression: Roughly 50% reduction in bandwidth and storage compared to H.264 at the same quality. On 24/7 operation across 10+ cameras, that difference between half and full storage capacity compounds fast.
- Varifocal 3.3–10.2mm Lens: Post-install focal adjustment eliminates lens swaps and inventory. Covers wide common-area views (3.3mm end) through tighter entry or perimeter detail (10.2mm end).
- PoE (802.3af) Power Draw <13W: Safe margin on standard PoE switch allocation (15W per port). Single cable run simplifies rough-in and reduces dependency on separate AC infrastructure at the camera location.
- Integrated IR and Day/Night: No auxiliary lighting or ambient light dependency. Operates in dark storage areas, unlit corridors, parking structures, and other low-light venues without compromise.
Deployment Considerations:
- 2MP is adequate for identification at typical indoor distances (lobby, retail floor, entry point), but falls short if facial detail is critical at 30+ feet or more. Right-size based on coverage distance and identification requirement.
- Audio input requires local NVR or VMS configuration for microphone sensitivity and recording enablement. Don't assume audio 'just works' — plan integration upfront, especially in multi-site deployments.
- Confirm PoE switch capacity before specifying multiple units. A 24-port PoE switch can comfortably power 10–12 of these cameras and still have headroom for other devices. Oversubscription is common but reduces margin for firmware updates or power spikes.
The NDI-3702-AL is well-suited to retail, office, hospitality, and education environments where discrete dome form factor, infrared operation, and audio integration justify the modest 2MP footprint. If your coverage distance is short and ID isn't critical, the bandwidth and storage efficiency of H.265 combined with flexible varifocal framing delivers real operational value.
