Serage SRDT5FW | 5MP TVI Night Light Turret Camera | 2.8mm Fixed Lens, 20m IR, IP66

Yes, in most cases - the SRDT5FW outputs AHD, HD-TVI, HD-CVI or CVBS (composite video baseband signal) over the same coaxial cable via ACP (AHD Coax Protocol), and it will run on existing RG59 or 5C-2V coax rather than requiring a new pull. The only re-cabling typically needed is if the existing run is in poor condition or exceeds sensible length for the resolution you intend to run.

The datasheet quotes a maximum of 300m using 5C-2V coax; this is a best-case figure and the manufacturer doesn’t publish a specific RG59 distance, so treat RG59 runs as shorter in practice. Actual usable distance depends on cable quality, connectors, and the video format selected, so test longer or older runs before final termination rather than relying on the headline figure.

Generally yes, provided the DVR’s input channel is set to a matching format (AHD, TVI, CVI or CVBS) - HD-over-coax formats aren’t brand-locked in the way some proprietary IP systems are. However, feature-level compatibility (such as ACP control, OSD menus or auto-format detection) can vary between manufacturers, so confirm with your DVR’s documentation or the manufacturer if you’re relying on those extras.

All four are ways of carrying video over coax; the SRDT5FW supports each, but maximum resolution and frame rate depend on which one you select - for example, 5MP is only achievable at 20fps in AHD/TVI mode, while CVBS caps out at 960H. In practice, use whichever format your existing DVR supports, and only choose between AHD/TVI/CVI on the camera side if your recorder gives you that choice.

5MP comfortably exceeds the 2MP-equivalent image quality typically expected for facial identification and evidential use, but specific URN or insurer requirements can vary by force or policy. Check the exact wording of your local requirement or insurer’s specification rather than assuming resolution alone is sufficient - factors like lens angle, lighting and storage retention also come into play.

Yes, it’s IP66-rated with a metal housing and an operating range of -30°C to 55°C, which covers most exposed UK external locations including driving rain and frost. As with any external camera, mounting it under an eave or canopy where possible will reduce direct weather exposure and help maintain the housing’s condition over time.
