SDTNOVA HD SDI Camera With Varifocal Lens

Features include a 1/2.8 CMOS sensor and HD-SDI 2 MP 1080P output with CVBS. It provides an OSD menu with D-WDR and DS-WDR, and a 2.8-12mm manual varifocal 3MP lens. The camera delivers real-time transmission with no compression and low signal loss. Best for security rooms or small-business surveillance that requires reliable, latency-free HD output.
Best for: Small to medium security setups needing clear 1080P streams with adjustable focal length. Choose this if you want straightforward, low-latency SDI output and a broad dynamic range via WDR modes. Limitations: Fixed 12V power requirement and manual focus control may require on-site adjustment.
SDTNOVA 3G-SDI HD Camera With Telephoto Varifocal Lens

Features include a 1/2.8″ high-sensitivity CMOS sensor with 3G/HD-SDI output and a 2.8-12mm manual varifocal telephoto lens. It supports multiple resolutions up to 1080P60/50/30/25P with CVBS output. The camera is compatible with switchers and other devices, providing real-time, low-latency transmission. Best for: Live production or security setups that require flexible frame rates and reliable SDI output with compatibility to complex AV ecosystems.
Best for: Users who need broad compatibility with video switchers and streaming encoders. Choose this if you plan multi-camera live streams. Limitation: Larger footprint than ultra-compact options.
MOKOSE Mini SDI Camera With 3.6mm Lens

This compact SDI camera uses a 1/2.8 CMOS sensor with 2 MP 1080P output and offers an OSD menu including D-WDR and DS-WDR. It ships with a 3.6mm fixed focal lens, delivering reliable HD imagery in tight spaces. Best for: Discreet surveillance or installations where space is at a premium. Limitations: The fixed 3.6mm lens lacks zoom, so field of view cannot be adjusted after installation.
Best for: Small offices or retail environments needing a minimal footprint camera without sacrificing SDI reliability. Opt for this when you want a simple, plug-and-play option. Caution: Fixed focal length reduces flexibility in setup changes.
MOKOSE 3G/HD SDI Camera With Varifocal Lens

Equipped with a 1/2.8 CMOS sensor, this camera supports 3G/HD-SDI and CVBS outputs. The 2.8-12mm manual varifocal lens offers wide-to-telephoto framing, and image quality reaches 1080P through uncompressed, low-latency transmission. Best for: Versatile production setups or security deployments that demand adjustable framing and robust SDI output. Limitation: Requires careful wiring to maximize 3G-SDI benefits in complex networks.
Best for: Live events or surveillance projects needing flexible focal length and solid compatibility with switchers. Avoid this if you need an ultra-wide fixed focal length for tight rooms; the zoom range helps but may complicate calibration.
SZYSDMOBCAM Micro HD / 3G-SDI Camera

Compact HD/3G-SDI camera with a micro footprint and 1080P/60 SDI output. It includes a small lens and supports uncompressed, low-latency transmission for real-time video. Best for: Concealed installations or spaces where camera size matters but SDI reliability remains essential. Limitation: The micro size may limit advanced lens options and long-term expansion in some setups.
Best for: Tight install environments or projects requiring discreet hardware with SDI output. Choose this if you need a tiny form factor without sacrificing SDI performance. Caution: Lens options are limited by the compact design.
Buying Guide: Key Considerations For SDI Cameras
- Output format and latency: Prioritize cameras that offer SDI with low latency and, if needed, CVBS as a compatibility fallback. For live production, aim for uncompressed 1080P at 60/50 FPS when possible.
- Sensor size and image quality: Larger sensors and modern CMOS sensors improve low-light performance and dynamic range. Consider cameras with WDR features (D-WDR/DS-WDR) for challenging lighting.
- Lens flexibility: Varifocal lenses (e.g., 2.8-12mm) enable precise framing, while fixed lenses simplify setup. Ensure lens mounting is compatible with your enclosure and view requirements.
- Form factor: Compact cameras fit tight spaces, but may limit lens options. Larger models often provide more robust control and better heat dissipation for longer sessions.
- Power and connectivity: Check whether the camera uses DC12V and ensure your power infrastructure supports it. Verify compatibility with your switchers, recorders, and video matrices.
- Compatibility with AV workflows: Cameras with 3G/HD-SDI outputs integrate more easily with professional switchers, encoders, and capture cards. Consider devices that support standard resolutions and frame rates you routinely use.
- Maintenance and installability: OSD menus help on-site calibration, but ensure you have access to on-screen controls and that the camera can be mounted in your space (ceiling, wall, or desk).
Frequently Asked Questions
- What does SDI mean for camera outputs?
SDI is a professional digital video interface offering clean, long-distance transmission with low latency and minimal compression, suitable for video production and surveillance.
- Is 1080P SDI sufficient for security cameras?
Yes, 1080P SDI provides clear, high-resolution images for most security and live streaming needs, with predictable performance over coaxial cables.
- What’s the advantage of a varifocal lens on an SDI camera?
A varifocal lens lets you adjust the focal length to fit a scene, improving framing without moving the camera, which is useful in surveillance corridors or classrooms.
- Can I mix SDI cameras with HDMI or IP cameras?
Yes, in many setups you can integrate SDI cameras with HDMI or IP cameras via switchers or encoders, but verify latency and synchronization across devices.
- Do SDI cameras require specific power supplies?
Most SDI cameras use DC12V adapters; verify the power requirements and ensure the supply has adequate amperage for continuous operation.
