Bosch NDE-3702-AL vs Bosch NDE-8702-RX: Specification Comparison
Both the Bosch NDE-3702-AL and NDE-8702-RX are 2MP (1920×1080) outdoor varifocal dome cameras from Bosch's FLEXIDOME line, designed for perimeter and surveillance applications. While they share the same resolution class and form factor, they differ meaningfully in sensor size, frame rate, low-light sensitivity, WDR performance, vandal resistance, and analytics depth — all factors that influence placement decisions in commercial and critical-infrastructure projects. This comparison examines those spec-level differences to help installers and IT buyers determine which unit fits their specific deployment scenario.

How do the imaging specs compare?
The NDE-8702-RX carries a larger 1/1.8" CMOS sensor versus the NDE-3702-AL's 1/2.8" sensor. This directly underpins the NDE-8702-RX's significantly lower minimum illumination figures: 0.009 Lux color / 0.0007 Lux B/W, compared to the NDE-3702-AL's 0.06 Lux color / 0.016 Lux B/W. For scenes with minimal ambient light — parking structures, loading docks, or unlit perimeters — the NDE-8702-RX requires roughly 6–7× less light to produce a color image. The NDE-8702-RX also delivers a wider dynamic range of 141 dB versus 120 dB on the NDE-3702-AL, a meaningful advantage in high-contrast scenes such as building entrances with bright exteriors and dark interiors.
Frame rate is another differentiator: the NDE-8702-RX is specified at 60 fps at 1080p, while the NDE-3702-AL is specified at 30 fps at 1080p. The 60 fps capability reduces motion blur on fast-moving subjects, which matters for forensic review of individuals or vehicles. Lens ranges differ slightly — 3.3–10.2 mm (motorized varifocal) on the NDE-3702-AL versus 4.4–10 mm on the NDE-8702-RX — giving the NDE-3702-AL a marginally wider minimum field of view. IR range is specified at 30 m for the NDE-3702-AL; the NDE-8702-RX datasheet does not provide a discrete IR range figure in the supplied specifications.
What about installation and environment?
Both cameras carry IP66 ingress protection and are rated for outdoor use, and both support wall, ceiling, pole, pendant, and rack mounting. Vandal resistance diverges: the NDE-3702-AL is IK10-rated (withstands 20 J impact), while the NDE-8702-RX achieves IK11 (withstands 50 J impact) — the highest standardized IK rating, making it the appropriate choice for exposed or high-risk locations such as parking garages, retail exteriors, or correctional environments where deliberate physical attack is a credible threat.
Operating temperature range also separates the two units. The NDE-8702-RX is specified for -50 °C to +60 °C (-58 °F to +140 °F), versus -30 °C to +50 °C (-22 °F to +122 °F) for the NDE-3702-AL. In extreme-cold climates — northern installations, cold-storage facilities, or high-altitude sites — the NDE-8702-RX's broader thermal tolerance is a direct installation requirement, not a preference. Both cameras list PoE+ (802.3at) as their power input per the provided specs, and both use shielded RJ45 connectors. Housing material for the NDE-3702-AL is specified as aluminum; the NDE-8702-RX housing material is not stated in the supplied specifications.
Which fits your VMS and analytics better?
Both cameras declare ONVIF compliance — the NDE-3702-AL specifies ONVIF Profile T with Auto-MDIX, and the NDE-8702-RX lists ONVIF without a profile designation in the supplied specifications. Both support H.265, H.264, and MJPEG compression and include local microSD/SDHC/SDXC edge storage. The NDE-3702-AL supports 3 simultaneous streams; the NDE-8702-RX supports 4 simultaneous streams, which may benefit installations feeding multiple VMS recorders, a live wall, and an analytics engine concurrently.
Analytics depth favors the NDE-8702-RX: it is specified with IVA Pro Buildings, IVA Pro Perimeter, and IVA Pro Privacy, versus IVA Pro Buildings only on the NDE-3702-AL. The NDE-8702-RX also lists a Crypto coprocessor (TPM) with RSA 4096-bit and AES/CBC 256-bit encryption in its Ethernet/security specification, and it is noted as a 'Trainer' camera — a designation associated with Bosch's AI training-capable edge analytics. The NDE-3702-AL lists TLS 1.2, AES 256, and AES 128 encryption. Audio input is built-in on both; the NDE-3702-AL explicitly notes a built-in microphone, while the NDE-8702-RX lists 'microphone supported.' Alarm I/O is specified on the NDE-8702-RX; it is not listed for the NDE-3702-AL in the supplied specifications.
Which should you choose: the NDE-3702-AL or the NDE-8702-RX?
Our take: The NDE-8702-RX is the stronger choice when low-light sensitivity, extreme-temperature tolerance, or advanced edge analytics are primary requirements. Its 1/1.8" sensor achieves 0.009 Lux color versus the NDE-3702-AL's 0.06 Lux — a 6.7× advantage in minimal-light environments. Its IK11 impact rating withstands 50 J versus IK10 at 20 J, making it the appropriate selection for high-vandal-risk installations. And its operating range of -50 °C to +60 °C covers deployments the NDE-3702-AL (rated to -30 °C) cannot. Additional differentiators include 60 fps versus 30 fps, 141 dB versus 120 dB WDR, a fourth simultaneous stream, and expanded analytics (IVA Pro Perimeter and Privacy beyond Buildings). The NDE-3702-AL is a practical fit where those extended capabilities are not required and where its wider minimum focal length (3.3 mm vs 4.4 mm) or any project-specific factors — such as price tier or mounting constraints — favor a proven mid-range varifocal dome.

Frequently Asked Questions
Which should you choose: the NDE-3702-AL or the NDE-8702-RX?
The NDE-8702-RX is the stronger choice when low-light sensitivity, extreme-temperature tolerance, or advanced edge analytics are primary requirements. Its 1/1.8" sensor achieves 0.009 Lux color versus the NDE-3702-AL's 0.06 Lux — a 6.7× advantage in minimal-light environments. Its IK11 impact rating withstands 50 J versus IK10 at 20 J, making it the appropriate selection for high-vandal-risk installations. And its operating range of -50 °C to +60 °C covers deployments the NDE-3702-AL (rated to -30 °C) cannot. Additional differentiators include 60 fps versus 30 fps, 141 dB versus 120 dB WDR, a fourth simultaneous stream, and expanded analytics (IVA Pro Perimeter and Privacy beyond Buildings). The NDE-3702-AL is a practical fit where those extended capabilities are not required and where its wider minimum focal length (3.3 mm vs 4.4 mm) or any project-specific factors — such as price tier or mounting constraints — favor a proven mid-range varifocal dome.
Is the NDE-3702-AL or NDE-8702-RX better for low-light performance?
Per the supplied specifications, the NDE-8702-RX is substantially more capable in low light. It requires only 0.009 Lux (color) and 0.0007 Lux (B/W) to produce an image, compared to 0.06 Lux color and 0.016 Lux B/W for the NDE-3702-AL. The NDE-8702-RX's larger 1/1.8" sensor versus the NDE-3702-AL's 1/2.8" sensor accounts for this gap. For poorly lit perimeters, underground parking, or any scene relying primarily on ambient light rather than IR fill, the NDE-8702-RX is the appropriate choice based on these specs.
Which camera is better suited for a vandal-prone or high-risk installation?
The NDE-8702-RX is specified at IK11 impact resistance — the highest standardized rating, capable of withstanding a 50 J impact. The NDE-3702-AL is IK10-rated, which covers 20 J. Both share IP66 ingress protection. If the deployment site involves risk of deliberate physical attack (exposed public areas, correctional facilities, retail exteriors), the NDE-8702-RX's IK11 rating provides a meaningfully higher level of mechanical protection per the specifications provided.
Can either camera operate in extreme cold, and does that affect my site selection?
Yes, and the difference is significant. The NDE-8702-RX is specified for operation down to -50 °C (-58 °F), while the NDE-3702-AL's lower limit is -30 °C (-22 °F). For installations in northern climates, cold-storage warehouses, or high-altitude outdoor environments where ambient temperatures can drop below -30 °C, only the NDE-8702-RX meets the operating envelope based on the specs provided. Both cameras share the same upper limit of +50 °C to +60 °C.
