ACTi Q450 vs Pelco SRXF3-8180-ERS: Specification Comparison
Both the ACTi Q450 and Pelco SRXF3-8180-ERS are outdoor-rated, 8MP fixed cameras designed for wide-area perimeter and entrance coverage using a single unit. The Q450 achieves its panoramic view through dual 2.8mm lenses in a bullet form factor, while the SRXF3-8180-ERS uses a single 2.7mm fisheye lens. This comparison evaluates their imaging characteristics, installation requirements, and platform integration capabilities for installers and IT buyers evaluating wide-area coverage solutions.

How do the imaging specs compare?
Both cameras deliver 8MP resolution with 180° horizontal field of view, but they achieve it differently. The ACTi Q450 uses two fixed 2.8mm lenses to produce its 180° HOV panoramic image, while the Pelco SRXF3-8180-ERS uses a single 2.7mm f/2.5 fisheye lens (aperture also listed as F2.0) with a maximum sensor output of 3264 x 2448 pixels at 12.5 fps full resolution. The Q450's frame rate at full resolution is not specified in the provided data.
Both units incorporate WDR and integrated IR illumination for low-light and day/night operation. The Q450 lists Adaptive IR with Day/Night switching. The SRXF3-8180-ERS specifies 850nm IR illumination covering the full 180° field, with WDR rated up to 83dB. Neither camera's IR range in meters is specified in the provided data for either model. The Pelco unit also supports de-warping for virtual PTZ views per its product description; the Q450's dual-lens approach delivers a stitched panoramic image directly.
What about installation and environment?
The Pelco SRXF3-8180-ERS carries IP66 and NEMA 4X environmental ratings plus an IK10 impact resistance rating, and is rated for operation from -40°C to +60°C. Its fisheye form factor supports wall, ceiling, pole, pendant, and corner mounting. It is powered via PoE+ (802.3at, Class 3). Housing color is white and dimensions are 6" x 6" x 2.81".
The ACTi Q450 uses a panoramic bullet form factor and is powered via standard PoE at 13W. Its IP/IK rating and operating temperature range are not specified in the provided data. This is a meaningful gap for buyers evaluating outdoor or harsh-environment deployments, where the Pelco unit's documented -40°C to +60°C range and IK10 rating provide verifiable specification assurance.
Which fits your VMS and analytics better?
The ACTi Q450 declares ONVIF compliance and is described as compatible with ONVIF-compliant VMS platforms. The Pelco SRXF3-8180-ERS specifies ONVIF Profile S and Profile T compliance, which are more granular conformance levels covering streaming and advanced video features respectively. Neither unit's specific VMS compatibility list beyond ONVIF is provided in the available specifications.
The Pelco SRXF3-8180-ERS includes Pelco Smart Analytics with 8 configurable behavior-based analytics onboard, microSD local storage support, HTTPS encryption, and microphone support for audio. The ACTi Q450 does not list onboard analytics, edge storage, audio capability, or HTTPS encryption in the provided specifications. For deployments requiring edge analytics, local recording redundancy, or audio capture, the Pelco unit offers documented capabilities that the Q450 specs do not address.
Which should you choose: the Q450 or the SRXF3-8180-ERS?
Our take: The SRXF3-8180-ERS is the stronger choice when environmental resilience, edge analytics, and detailed ONVIF compliance documentation are decision criteria. Pelco specifies IK10 impact resistance and a -40°C to +60°C operating range versus no equivalent ratings published for the Q450. The SRXF3-8180-ERS includes 8 onboard Smart Analytics behaviors and microSD edge storage, neither of which appears in the Q450's available specifications. ONVIF Profile S and T compliance on the Pelco unit provides more defined interoperability than the Q450's general ONVIF declaration. The Q450's dual-lens bullet design may be preferred where a lower-profile wall-mount form factor is operationally advantageous or where standard PoE (13W) infrastructure is in place and PoE+ is unavailable. Buyers should obtain full Q450 environmental and frame-rate specifications from ACTi before finalizing any outdoor or impact-risk deployment comparison.

Frequently Asked Questions
Which should you choose: the Q450 or the SRXF3-8180-ERS?
The SRXF3-8180-ERS is the stronger choice when environmental resilience, edge analytics, and detailed ONVIF compliance documentation are decision criteria. Pelco specifies IK10 impact resistance and a -40°C to +60°C operating range versus no equivalent ratings published for the Q450. The SRXF3-8180-ERS includes 8 onboard Smart Analytics behaviors and microSD edge storage, neither of which appears in the Q450's available specifications. ONVIF Profile S and T compliance on the Pelco unit provides more defined interoperability than the Q450's general ONVIF declaration. The Q450's dual-lens bullet design may be preferred where a lower-profile wall-mount form factor is operationally advantageous or where standard PoE (13W) infrastructure is in place and PoE+ is unavailable. Buyers should obtain full Q450 environmental and frame-rate specifications from ACTi before finalizing any outdoor or impact-risk deployment comparison.
Is the Q450 or SRXF3-8180-ERS better for low light?
Both cameras include integrated IR illumination and Day/Night operation with WDR. The Pelco SRXF3-8180-ERS specifies 850nm IR covering the full 180° field and WDR up to 83dB. The ACTi Q450 lists Adaptive IR and WDR but does not specify IR wavelength, IR range in meters, or a WDR dB rating in the available data. Based on published specifications alone, the Pelco unit provides more verifiable low-light performance detail.
Which camera requires less infrastructure — the Q450 or the SRXF3-8180-ERS?
The ACTi Q450 operates on standard PoE at 13W, meaning it is compatible with 802.3af PoE switches. The Pelco SRXF3-8180-ERS requires PoE+ (802.3at, Class 3), which draws up to 30W and requires a PoE+ capable switch or injector. If your existing switch infrastructure is 802.3af only, the Q450 may integrate with less additional cost, provided its environmental ratings are confirmed to meet site requirements.
Do both cameras support onboard recording if the network goes down?
Only the Pelco SRXF3-8180-ERS specifies local edge storage via microSD card in the available product data. The ACTi Q450 does not list onboard storage capability in its provided specifications. Buyers requiring local recording redundancy should confirm Q450 storage support directly with ACTi before deployment.
