FAQs about Bosch FLEXIDOME 3100I IR Security Camera

How good is the infrared at night?

The integrated IR system is one of the strongest practical features of the 3100i IR model.

Bosch rates the integrated illuminator for distances of up to 30 meters, or approximately 98 feet.

The lens is also IR corrected, and the IR intensity can be adjusted. The camera switches between day and night operation using an IR-cut filter.

That does not mean you should expect a perfectly illuminated 98-foot scene under every installation condition.

The 30-meter figure is a maximum viewing-distance specification, not a guarantee that every object at 30 meters will be equally well illuminated or identifiable.

Actual results depend on the scene, reflective surfaces, weather, mounting position, lens setting, and the size and reflectivity of the subject.

This distinction is particularly important with dome cameras because nearby walls, ceilings, signs, or other reflective objects can affect how IR behaves.

For normal entrances, driveways, building perimeters, loading areas, and similar installations, the integrated IR makes the camera considerably more flexible than a camera that depends entirely on ambient light.

Does the camera still work when there is almost no ambient light?

Yes. The IR illuminator is intended for scenes where normal ambient lighting is insufficient.

Bosch also combines this with low-light imaging, HDR, and day/night processing.

The interesting part is that the camera is not dependent on IR for every dark scene, according to TechPally.

In suitable low-light conditions, the sensor and image processing can still produce useful images before the camera needs to rely heavily on infrared.

That gives installers more options when dealing with changing lighting conditions.

What does IK10 actually mean in everyday use?

It means the housing has been designed to withstand a high level of mechanical impact.

That is useful for locations where someone might try to hit, tamper with, or damage the camera.

It does not make the camera indestructible.

An IK10 dome can still be damaged by sufficiently severe force, improper installation, or deliberate attacks using tools beyond the test conditions.

The rating should therefore be viewed as an important layer of physical protection rather than a guarantee against vandalism.

Is firmware something owners need to pay attention to?

Absolutely. This is one area where professional users should be more careful than casual buyers.

The NDE-3703-AL is part of Bosch's CPP14.3 platform.

Bosch's current knowledge base identifies the NDE-3702-AL and NDE-3703-AL as CPP14.3 cameras and explains that the Common Product Platform determines which firmware branch applies to a camera.

Current Bosch product documentation also lists CPP14 firmware releases for the 3100i family.

This is important because Bosch firmware is organized around its Common Product Platform system.

You should not simply download a firmware file because the version number looks newer.

Before updating, confirm the camera's exact model and platform.

This becomes particularly important in larger deployments.

Does the camera work with third-party VMS platforms?

It can. ONVIF support makes third-party integration much more realistic than it would be with a completely proprietary camera.

However, there is an important difference between compatibility and full integration.

A third-party VMS may display and record the camera perfectly while not exposing every Bosch-specific analytic function.

If your project depends heavily on IVA Pro Buildings, Bosch-specific events, forensic search, or other advanced functions, verify those features with the specific VMS before purchasing a large number of cameras.

This is one of the situations where an integrator's test installation is more useful than a product brochure.

What about Milestone and other professional VMS systems?

Bosch cameras are commonly used in professional VMS environments, and discussions around Bosch cameras frequently involve systems such as Milestone.

However, integration quality depends on the exact camera, firmware, VMS version, driver, and configuration.

The safest approach is to test the exact NDE-3702-AL or NDE-3703-AL with the exact VMS version you intend to deploy.

This is especially important if analytics events need to be passed from the camera into the VMS.

Does the camera need a special Bosch network?

No. It uses standard IP networking and PoE.

The camera can therefore be deployed on a normal managed Ethernet surveillance network, provided the switch, cabling, VLANs, PoE budget, and network architecture are correctly designed.

The PoE support is particularly convenient because one Ethernet cable can carry both power and network data.

For a professional installation, however, the network should be designed with security cameras in mind rather than simply connecting everything to the same unrestricted LAN.

How much power does it need?

The exact power requirement depends on the operating configuration, but the camera is designed for PoE operation.

This is another area where the IR system matters. Nighttime operation can change power consumption, so the PoE switch should have enough total power capacity for the camera under expected operating conditions.

This point becomes particularly important when many cameras are connected to the same switch.

The broader Bosch community has discussed PoE and power-related issues with other high-end FLEXIDOME models, including cases where cameras demanded more power than expected from network switches.

Those reports involve different models, so they should not be treated as evidence of a 3100i defect.

They are nevertheless a useful reminder to check the PoE budget instead of assuming every camera will draw the same amount of power.

What is the biggest mistake a buyer could make?

Buying the camera based only on the specification sheet.

The camera may have 5MP resolution, IR, HDR, analytics, and a varifocal lens, but none of those features can compensate for a poor installation.

Before buying, determine:

• What area needs to be covered?

• How far away is the subject?

• Do you need identification or general monitoring?

• What lighting exists at night?

• Is there a strong backlight?

• How much storage is required?

• What VMS or NVR will be used?

• Will analytics events need to be integrated?

• What PoE switch will power the camera?

• What network segmentation will be used?

• How will the camera be maintained and updated?
