GEM Co-ax 2MP Lite Varifocal Bullet 2.8-12mm

Overview

The GEM Co‑ax 2MP Lite Varifocal Bullet (model CAM1600W) is a professional‑grade analogue/hybrid surveillance camera designed for both domestic and commercial environments. With a full metal bullet housing, a wide‑range 2.8‑12 mm varifocal lens, and multi‑format output (TVI, CVI, AHD or CVBS), it delivers flexibility and performance. According to the official specification:

• 2 MP resolution (Full HD)

• Varifocal lens 2.8‑12 mm 

• “4‑in‑1” multi‑format (TVI, CVI, AHD, CVBS) output 

• Full metal body / bullet‑style housing

• Designed for covering larger areas with a more substantial presence

Key Features & Benefits

• Varifocal 2.8–12 mm lens: This zoom‑adjustable lens gives you the flexibility to tailor your field of view — from a wider angle (when set near 2.8 mm) to a tighter, more focused view at 12 mm. Ideal for installations where the exact area requiring monitoring might change or needs fine tuning.

• Multi‑format compatibility (TVI/CVI/AHD/CVBS): The camera supports multiple analogue/hybrid formats, making it highly compatible with a broad range of DVR systems and facilitating upgrades or integration into mixed‑technology systems.

• 2 MP resolution: Provides Full HD (1920 × 1080) clarity for detailed monitoring and recording. This is sufficient for recognition tasks (faces, evidence capture) while being efficient in storage and bandwidth.

• Robust bullet housing: With a full‑metal body the CAM1600W gives a professional and durable appearance, withstanding typical indoor or outdoor usage, and its larger housing offers deterrence value.

• Hinged bracket: Offers adjustable mounting, making it simpler to install and aim for optimal coverage angles. 

• Ideal for larger area coverage: The combination of the varifocal lens plus bullet form factor means this camera is well‑suited for driveways, car parks, building perimeters, industrial yards, and similarly sized areas.

Applications

• Commercial premises: retail outlets, warehouses, factories where flexible angle coverage is needed.

• Residential/small business sites: driveways, garden perimeters, side entrances, garages.

• Upgrade paths: replacing older analogue cameras while retaining existing cabling and DVRs (thanks to the multi‐format support).

• Mixed systems: Integrates easily where some cams are AHD/TVI and others CVI/CVBS, simplifying inventory.

Installation & Considerations

• The 2.8‑12 mm lens should be manually adjusted at installation to frame the desired scene — for example, a wider view for general coverage, and a tighter zoom for specifically monitoring a doorway or passage.

• Since this is a “Lite” version (per the spec descriptor), ensure that the IR illumination and environmental/housing rating match the installation location (e.g., outdoor full exposure vs sheltered).

• Confirm compatibility of your DVR/recorder format (TVI, CVI, AHD or CVBS) and ensure proper DIP‑switch or menu configuration to switch formats if needed.

• Although the body is full metal, the specification does not list a specific weatherproof ingress rating (e.g., IP66/IP67) in the publicly cited spec. If exposed to harsh weather or marine environment, consider additional protective housing or verifying the rating with the vendor.

• Cable runs: Use suitably thick coaxial cable (e.g., RG59 or RG6 with power) and ideally separate power feed or regulated supply to maintain image stability over long runs.

Why Choose This Camera?
Choosing the GEM CAM1600W means opting for a reliable, flexible, full‑HD bullet camera with a manually adjustable varifocal lens and multi‐format output — giving you both current value and future flexibility. For installers or system integrators looking for a robust, professional bullet camera without more expensive motorised lenses or IP networking, this camera offers strong performance. The full‑metal build also adds physical deterrence and aesthetic credibility for commercial projects, while the lens flexibility allows precision in framing critical zones.
