Ajax 5MP 2.8mm Fixed Lens BulletCam

FAQs

What is the difference between the 2.8mm and 4mm lens versions?

The 2.8mm lens version offers a wider field of view (100°–110° viewing angle) compared to the 4mm version (75°–85° viewing angle). The 2.8mm lens is better suited for monitoring larger areas or rooms where you need maximum coverage, while the 4mm lens provides more detail at greater distances with a narrower field of view for focusing on specific zones like doorways or pathways.

How does the smart infrared backlight work?

The BulletCam features intelligent infrared illumination that automatically adjusts the intensity of the IR LEDs in real-time based on the scene. This prevents overexposure of objects that are too close to the camera while ensuring distant objects remain visible. The system provides up to 50 meters of infrared illumination range, delivering clear black-and-white footage in complete darkness without the washed-out appearance common with fixed-intensity IR systems.

Can I use the BulletCam without an Ajax NVR?

Yes, the BulletCam can operate as a standalone device. You can install a microSD card (32-256 GB capacity, V30 speed class or faster recommended) directly into the camera for local video storage. The camera can still be monitored and managed through the Ajax mobile and desktop applications without requiring an NVR.

What storage options are available for video recordings?

The BulletCam supports three storage options: local recording to a microSD card installed in the camera (32-256 GB), recording to an Ajax NVR hard drive when connected to the network video recorder, or cloud storage if a cloud archive subscription is activated through your Ajax account.

Does the camera support Power over Ethernet?

Yes, the BulletCam supports PoE (Power over Ethernet) according to the 802.3at/af standard. This allows the camera to receive both power and data through a single Ethernet cable, simplifying installation and reducing cable clutter. Alternatively, you can power the camera using an external 12V DC power supply (±20% tolerance, minimum 1A current recommended).

What is the maximum recording resolution and frame rate?

The BulletCam (5 Mp/2.8 mm) can record at a maximum resolution of 2880 × 1620 pixels at 25 frames per second, which is classified as 3K UHD quality. The camera supports various resolution options down to 1024 × 576 pixels, with frame rates adjustable from 3 to 25 fps depending on your bandwidth and storage requirements.

How do I add the camera to my Ajax system?

You can add the BulletCam to your Ajax system by scanning the QR code located on the camera enclosure using the Ajax mobile app. Alternatively, you can manually enter the device ID found on the QR code. The camera can be added as a standalone device or paired with an Ajax NVR if one is present on your network. Only system administrators or PRO users with configuration rights can add devices to the system.

Can the camera distinguish between different types of motion?

Yes, the BulletCam features AI-powered object recognition that can identify and distinguish between humans, pets, and vehicles. You can configure the camera to send notifications or activate sirens based on specific object types, significantly reducing false alarms from irrelevant motion such as moving foliage or passing shadows.

Is the camera suitable for outdoor installation?

Yes, the BulletCam is specifically designed for outdoor use. It features an IP65-rated weatherproof metal enclosure that protects against dust ingress and water jets from any direction. The robust metal housing also provides vandal resistance. The camera operates reliably in temperatures ranging from -30°C to +60°C (-22°F to +140°F), making it suitable for harsh weather conditions.

What is True WDR and why is it important?

True WDR (Wide Dynamic Range) is a hardware and software technology that helps the camera capture clear images in scenes with both very bright and very dark areas simultaneously. This is particularly useful when monitoring entrances with bright outdoor light and darker indoor areas, or parking lots with strong overhead lighting and shadowed zones. True WDR ensures details are visible in both zones without overexposure or underexposure, unlike basic digital WDR found in lower-end cameras.

Can I access the camera remotely?

Yes, you can access the BulletCam remotely through the Ajax mobile apps (iOS and Android) or Ajax PRO Desktop application. The camera uses secure, encrypted connections via the Ajax Cloud, allowing you to watch live streams, review archived footage, and adjust camera settings from anywhere with an internet connection.

Does the camera record audio?

Yes, the BulletCam includes a built-in digital microphone that supports the G.711 audio codec. Audio capture and playback can be enabled in the camera settings, allowing you to record and review video with synchronized sound. This can provide valuable additional context for security events.

How many users can access the camera simultaneously?

The BulletCam supports up to 200 users per space, with granular access controls. System administrators can configure specific permissions for each user, including view-only access, and can set up temporary access links for contractors or guests. Up to 5 users can view live streams simultaneously from a single camera.
