Product Features
What's in the Box
Compact, Smart, Stylish, and Built to Last
Tidy Installation with Optional Bracket
The optional spacer bracket hides cables in the base, adds side trunking holes, and its 52 mm height raises the camera for a better view.
Ultra-Compact Dome Design
A modern take on the classic bullet camera, BabyBullet measures just 71 × 66 mm at the front, 100 mm bullet length, and only 175 mm overall. The most compact in our range, yet still packed with all the high-tech features you expect.
BabyBullet vs Premio
Both part of our Fantastech-4 range, BabyBullet is far smaller than Premio. Premio has a 5× auto-zoom lens and four Fusion Light bulbs, while BabyBullet has two – ideal for homes and small businesses, with Premio for larger sites.
Modern, Familiar Styling
With an IP67 metal body built for the harshest British weather, BabyBullet works indoors or out. Traditionally suited to outdoor use, it can be mounted on ceilings or walls, with an adjustable arm to set the perfect angle.

Zxtech Advanced People & Car Detection Technology
Powered by 4GB of integrated DDR3L memory, this camera is engineered for uncompromising 24/7 stability. It seamlessly handles 4K main stream, sub-stream, AI processing, ONVIF and snapshot services simultaneously, while supporting larger AI models for precise human and vehicle detection, line crossing and intrusion alerts. The expanded memory headroom also ensures smooth high-bitrate performance today and capacity for future AI upgrades — a level of internal architecture many lower-memory cameras simply cannot match.
Powered by Sony STARVIS™ technology using the IMX415 sensor for true 4K and IMX335 for 5MP, built on a large 1/2.8” sensor for enhanced light capture and reduced noise, this system delivers ultra-low light performance down to 0.0005 Lux, ensuring intruders remain clearly visible even in near-dark conditions. Advanced 120dB to 140dB Wide Dynamic Range balances extreme contrast scenes, making it ideal for strong backlight environments, doorway protection and licence plate clarity, providing the high-quality image foundation essential for precise and reliable AI detection in real-world surveillance scenarios.
Introducing Zxtech’s advanced 4K CCTV system, powered by a 2 TOPS AI engine for fast, real-time intelligent detection. Beyond standard features such as Motion Detection, Mobile Alerts, Masking and Scheduling, our cameras utilise dedicated AI processing to accurately identify humans and vehicles while reducing false alarms from rain, animals or moving shadows. Create precise intrusion or line-crossing zones and receive instant alerts or trigger recordings the moment a real threat is detected. With hardware-level AI performance built directly into the system, Zxtech delivers proactive, reliable security designed to prevent incidents rather than simply record them.

What is Stealth IR, Colour LED & Fusion Light?
What is Stealth IR, Colour LED & Fusion Light?
Stealth IR – No-glow infrared for discreet black-and-white night vision.
Colour LED – Powerful 4000K white floodlights that activate in low light, delivering crystal-clear, full-colour images even at night.
Fusion Light – A Zxtech innovation combining Stealth IR and Colour LED in one bulb. Starts in neighbour-friendly Stealth IR by default; when optionally activated by the user, AI switches between discreet black-and-white and ultra-bright colour night vision on motion detection for maximum security.
Deep bases aren’t essential but are perfect for a tidy, professional look. They hide cables neatly inside, allow side cable entry, and even raise the camera height for a better angle. Think of them as spacers, brackets, or junction boxes for the sleekest finish.
