Geovision SD4825W-IR00 vs i-PRO A-475-P: Specification Comparison
Both the Geovision SD4825W-IR00 and the i-PRO A-475-P are 4MP PTZ cameras with IR night vision, PoE connectivity, and ONVIF compliance—placing them squarely in the same resolution class and camera type for cross-shopping purposes. The key differentiation lies in zoom range (25x vs. 4x optical), PoE class (802.3at vs. 802.3af), and VMS ecosystem depth. This comparison is drawn entirely from the provided specifications; where a spec is absent for either model, that is noted explicitly.

How do the imaging specs compare?
Both cameras deliver 4MP resolution and use H.265/H.264 compression. The Geovision SD4825W-IR00 offers a 25x optical zoom lens, making it suited for large open-area surveillance where distant subject identification is required. The i-PRO A-475-P provides a 4x optical zoom varifocal lens, more appropriate for shorter-range applications in the 40–60 ft forensic-ID range cited in its product bullets. Neither model's sensor size, horizontal field of view, or maximum frame rate is provided in the supplied specifications.
On low-light performance, the SD4825W-IR00 specifies 'Super Low Lux' minimum illumination alongside integrated IR, and lists WDR as a supported feature. The A-475-P specifies integrated IR but does not provide a minimum illumination figure or an explicit WDR designation in the supplied specs. The SD4825W-IR00's IR range is not numerically specified; the A-475-P's IR range is listed as 150 feet. Neither camera's exact IR wavelength or WDR dynamic range in dB is provided.
What about installation and environment?
The SD4825W-IR00 is PoE+ (802.3at) powered, which allows it to draw higher wattage over a single Ethernet cable—useful for a motorized 25x zoom dome with integrated IR illuminators. Mounting options listed are wall and ceiling. The A-475-P operates on standard PoE (802.3af) at a stated 13W, meaning it is compatible with a broader range of existing PoE switches without an 802.3at budget requirement. Its mount type is listed as 'Rack,' which is atypical for a PTZ camera and may reflect a data entry artifact; the supplied specs do not include a ceiling or wall mounting designation for this model.
IP/IK ingress and impact ratings, operating temperature range, and enclosure material are not provided in the supplied specifications for either camera. Buyers requiring outdoor-rated or vandal-resistant deployment should consult the manufacturer datasheets directly before specifying either unit.
Which fits your VMS and analytics better?
The SD4825W-IR00 declares ONVIF compliance and lists compatibility with Geovision's GV-Control Center VMS. No additional third-party VMS certifications are provided in the supplied specs. The A-475-P declares ONVIF Profile S and lists verified compatibility with i-PRO NVR, Milestone, Genetec, and Axis Camera Station—a broader set of named enterprise VMS platforms from the provided data.
The A-475-P includes audio input and streaming capability, plus VMD (Video Motion Detection) edge analytics, per the supplied specs. The SD4825W-IR00's specs do not list audio input/output or any edge analytics features. Neither camera lists an SD card slot or onboard storage specification in the provided data.
Which should you choose: the SD4825W-IR00 or the A-475-P?
Our take: The SD4825W-IR00 is the stronger choice when long-range PTZ surveillance is the primary requirement—its 25x optical zoom versus the A-475-P's 4x optical zoom represents a substantial reach advantage for perimeter, parking lot, or campus-wide coverage. It also requires PoE+ (802.3at) infrastructure, whereas the A-475-P runs on standard 802.3af at a stated 13W, lowering switch compatibility requirements for the i-PRO unit. The A-475-P counters with a documented 150-foot IR range, audio input, VMD edge analytics, and named certification on Milestone, Genetec, and Axis Camera Station—capabilities not present in the SD4825W-IR00's provided specs. For integrators operating in Milestone or Genetec environments who need 802.3af compatibility and built-in audio, the A-475-P is the more ecosystem-ready option. For deployments demanding wide-area optical reach over a certified Geovision or ONVIF infrastructure, the SD4825W-IR00's zoom capability is the defining differentiator.

Frequently Asked Questions
Which should you choose: the SD4825W-IR00 or the A-475-P?
The SD4825W-IR00 is the stronger choice when long-range PTZ surveillance is the primary requirement—its 25x optical zoom versus the A-475-P's 4x optical zoom represents a substantial reach advantage for perimeter, parking lot, or campus-wide coverage.

The A-475-P counters with a documented 150-foot IR range, audio input, VMD edge analytics, and named certification on Milestone, Genetec, and Axis Camera Station—capabilities not present in the SD4825W-IR00's provided specs. For integrators operating in Milestone or Genetec environments who need 802.3af compatibility and built-in audio, the A-475-P is the more ecosystem-ready option. For deployments demanding wide-area optical reach over a certified Geovision or ONVIF infrastructure, the SD4825W-IR00's zoom capability is the defining differentiator.
Is the SD4825W-IR00 or A-475-P better for low-light performance?
The SD4825W-IR00 specifies 'Super Low Lux' minimum illumination and WDR alongside integrated IR, but does not provide a numeric IR range in the supplied specs. The A-475-P lists integrated IR with a 150-foot range but does not specify a minimum illumination value or WDR in the provided data. Neither camera's exact lux floor is given, so a definitive low-light ranking cannot be made from the supplied specifications alone—consult the manufacturer datasheets for measured lux values.
Which camera is easier to integrate with Milestone or Genetec VMS?
The A-475-P lists verified compatibility with both Milestone and Genetec in its provided specs, in addition to ONVIF Profile S. The SD4825W-IR00 lists ONVIF and Geovision GV-Control Center only; no Milestone or Genetec certification is present in the supplied data. For those VMS platforms, the A-475-P carries a lower integration risk based on the available information.
Do I need a PoE+ switch to run the SD4825W-IR00, and does the A-475-P work on standard PoE?
Yes—the SD4825W-IR00 specifies PoE+ (802.3at) as its power input, which requires a switch port capable of delivering up to 30W. The A-475-P specifies standard PoE (802.3af) at a stated 13W draw, making it compatible with a wider range of existing PoE infrastructure without an 802.3at upgrade.
