Bosch NDV-5703-AL 5MP Varifocal Dome Camera
The Bosch NDV-5703-AL is a compact indoor dome designed for deployments where field-of-view flexibility matters but relocating hardware doesn't. Its 3.2–10.5mm varifocal lens delivers a 3.3× zoom range, allowing operators to dial in the right framing during installation or via remote lens adjustment—critical when mounting height limits physical repositioning. The camera outputs 5MP resolution across H.265, H.264, and MJPEG codecs, powered entirely by standard PoE (802.3af), which means a single Ethernet run handles both video and power.
Overview
This dome bridges retrofit and new-build installations where either separate power runs aren't feasible or where centralized PoE switching already exists. The varifocal lens reduces the need for multiple fixed-focal-length cameras to cover a space; instead, one unit with adjustable optics can address wide-area coverage, facial detail, or license-plate capture depending on your zoom setting. The NDV-5703-AL pairs an IK10 vandal-resistant housing (rated for 20-joule impacts—roughly a 5kg object dropped from 40cm) with IP54 environmental sealing, meaning dust and spray won't compromise internal optics or electronics. Infrared day/night switching and onboard IR emitters extend usable coverage into complete darkness, enabling true 24/7 surveillance without auxiliary lighting.
Key Features
- 5MP Resolution (2592 × 1944): Delivers sufficient detail for facial recognition and license-plate capture on standard network infrastructure, without requiring 4K storage overhead or exotic bandwidth provisioning.
- Varifocal 3.2–10.5mm Lens: Provides 3.3× optical zoom, letting you adjust coverage from wide framing to narrow focus without physically repositioning the camera—essential in retrofit scenarios or where mounting location is fixed.
- H.265 Primary Codec: Cuts bandwidth and storage requirements roughly in half versus H.264 without quality loss—meaningful savings when recording 24/7 across a multi-camera system. H.264 and MJPEG fallback options preserve compatibility with legacy VMS platforms and congested network segments.
- PoE (802.3af) Powered: Draws under 13W, eliminating separate 12VDC or 24VAC power runs and centralizing power distribution to a standards-compliant PoE switch or midspan injector. No additional breakers or conduit required.
- Infrared Day/Night: Automatic switching to monochrome capture and IR emitter activation extends surveillance into darkness without external floods or auxiliary lighting infrastructure.
- IK10 Vandal Resistance: Housing withstands 20-joule direct impacts, protecting against hammer strikes or deliberate damage in unsecured or high-traffic areas where accessible cameras face mechanical stress.
- IP54 Environmental Rating: Sealed against dust ingress and direct water spray from any direction. Suitable for covered entries, outdoor eaves, loading docks, and damp indoor areas—not submersible, so skip this for submerged or fully outdoor unprotected installations.
- Built-in Microphone: Audio input enables two-way communication and incident verification; integrates with audio event logging in VMS platforms supporting ONVIF audio streams.
- Compact Dome Form Factor: Discreet ceiling or wall pendant mount blends into retail, educational, and light-industrial environments; low visual profile reduces psychological alarm-fatigue in occupied spaces.
Integration and Compatibility
The NDV-5703-AL outputs ONVIF-compliant video streams, integrating with third-party VMS platforms including Milestone XProtect, Genetec Security Center, and open-architecture network video recorders. Codec flexibility—H.265 for bandwidth-constrained networks, H.264 and MJPEG for legacy or resilience-critical deployments—ensures compatibility across both new and aging infrastructure. PoE power simplifies electrical design: a single PoE-enabled network switch can simultaneously power and feed video to multiple NDV-5703-AL units and other PoE cameras without strain on standard 802.3af budgets (typically 15W available per port). Audio via the built-in microphone supports voice communication and integrates with VMS-native audio recording and analytics where supported.
When to Choose a Different Model
If your application demands submersion-rated sealing (e.g., poolside, wet-wash facilities, fully outdoor unprotected exposure), upgrade to a higher IP rating—IP67 or above. If the site requires extreme long-range IR (50m+) or significantly wider optical zoom, consider a higher-megapixel variant within the Bosch Bosch IP camera line that pairs zoom with increased resolution. If two-way audio is non-negotiable and the built-in microphone proves insufficient for your acoustic environment, consult the datasheet for audio sensitivity specs or consider an external audio solution via ONVIF integration.
Frequently Asked Questions
Q: Will the NDV-5703-AL work with my existing Milestone XProtect VMS?
A: Yes. The camera outputs ONVIF-compliant streams, and both H.264 and H.265 codecs are widely supported by Milestone. Audio input via the built-in microphone is also compatible with Milestone audio recording features.
Q: How much power does the NDV-5703-AL draw, and will it overload my PoE switch?
A: The camera draws under 13W at maximum operation, fitting comfortably within a standard 15W 802.3af PoE budget per port. A typical managed PoE switch can support multiple NDV-5703-AL units without power exhaustion.
Q: Can I adjust the zoom remotely, or is the lens only set during installation?
A: The varifocal lens is adjustable remotely via the camera's web interface or VMS integration, allowing operators to refine framing after deployment without physical access.
Q: What's the maximum infrared range in complete darkness?
A: The onboard IR emitters extend usable coverage into full darkness, though exact range depends on scene reflectivity and lens zoom position. Consult the datasheet for detailed IR performance curves at various focal lengths.
Q: Is the NDV-5703-AL suitable for outdoor mounting?
A: The IP54 rating supports covered outdoor locations (eaves, covered entries, loading docks under awnings) where direct rain and sustained water exposure are avoided. For fully exposed outdoor unprotected mounting, choose a camera with IP66 or IP67 sealing.
Q: Does the camera support edge recording or local storage?
A: The camera is a network encoder with no built-in storage. Recording occurs on a remote NVR or VMS platform. Some third-party platforms support edge-triggered recording via ONVIF events, but verify your specific VMS feature set.

The NDV-5703-AL hits a practical sweet spot for retrofit and cost-conscious deployments. The 3.2–10.5mm varifocal lens eliminates the guesswork around optical coverage during pre-site surveys—you mount once, zoom remotely. The PoE (802.3af) power draw is genuine differentiation: at under 13W, you won't fragment your switch's power budget across dozens of cameras like you would with power-hungry PTZ or multi-sensor units.
Technical Highlights:
- H.265 Codec: Reduces storage overhead by roughly 50% versus H.264 on equivalent resolution and frame rate. Across 10+ cameras on 24/7 recording, that's a meaningful difference in NVR sizing and retention math.
- IK10 Vandal Rating: 20-joule impact rating (5kg dropped from 40cm) puts this in the protected-location category. It won't survive determined attacks, but it handles accidental bumps and casual vandalism that would shatter lower-rated housings.
- IP54 Sealed: Dust and spray ingress are non-issues indoors and in covered outdoor spaces. The limitation is water submersion and prolonged heavy rain exposure—IP66 or IP67 required for those scenarios.
Deployment Considerations:
- Varifocal adjustment happens remotely, but only after commissioning. Don't expect field technicians to nail zoom on first try without a network connection during installation—test with temporary PoE injector or pre-stage zoom setting before final mounting.
- Built-in microphone is useful for two-way talk-back and incident verification, but audio quality isn't studio-grade. Use it for communication, not forensic voice analysis.
- IP54 sealing is adequate for covered loading docks, eaves, and indoor spaces with spray risk (kitchens, washdowns under cover), but fails in unprotected outdoor direct-rain scenarios. Know your environmental boundary.
Deploy the NDV-5703-AL where you need flexible framing without repositioning, centralized PoE power infrastructure already in place, and rugged-but-not-extreme environmental protection. Retail back-of-house, educational facility hallways, municipal building entries, and light-industrial covered work areas are ideal. Skip it if you need 50m+ IR range, submersion sealing, or true outdoor unprotected mounting—different model required.
