ACTi Q450 vs Pelco SRXF3-8360-I: Specification Comparison
Both the ACTi Q450 and Pelco SRXF3-8360-I are 8MP fixed cameras designed for wide-area panoramic coverage, making them legitimate cross-shop candidates for installers seeking high-resolution, broad field-of-view surveillance without PTZ complexity. The Q450 achieves its panoramic view via dual 2.8mm lenses in a bullet form factor suited to perimeter and outdoor-oriented deployments, while the SRXF3-8360-I employs a single fisheye lens in a ceiling-mount dome optimized for indoor 360° coverage. This comparison evaluates imaging capability, installation fit, and integration depth based solely on published specifications.

How do the imaging specs compare?
The ACTi Q450 delivers 8MP resolution through two fixed 2.8mm lenses, each covering 90°, combining for a 180° horizontal field of view. It features Adaptive IR with Day/Night switching and Wide Dynamic Range. No minimum illumination lux value is provided in the Q450 specifications, and no specific IR range in meters is stated. Compression support includes both H.265 and H.264, with H.265 offering a bandwidth efficiency advantage over the Pelco unit.
The Pelco SRXF3-8360-I also carries an 8MP sensor, resolving at 3264×2448 (though a separate spec entry references 3840×2160, introducing an internal inconsistency in the provided data). Its single 2.7mm f/2.5 fisheye lens delivers both 180° and 360° viewing modes depending on dewarping configuration. A stated minimum illumination of 0.10 lux provides a concrete low-light benchmark absent from the Q450's specs. Frame rate is specified at 12.5 fps at full resolution; no equivalent figure is provided for the Q450. WDR is confirmed on both units, with the SRXF3-8360-I specifying up to 83dB WDR range.
What about installation and environment?
The ACTi Q450 is powered via standard PoE at 13W and is housed in a panoramic bullet form factor, implying suitability for wall or pole mounting on building perimeters. No IP ingress protection rating, IK impact rating, or operating temperature range is stated in the Q450 specifications, which limits confident outdoor deployment verification based on spec alone.
The Pelco SRXF3-8360-I is rated IP52 for ingress protection and IK10 for impact resistance, and draws power via PoE+ (802.3at, Class 3), requiring a PoE+ capable switch or injector. Its operating temperature range is specified as -10°C to +60°C (with a separate storage temperature reference of -10°C to +70°C). The unit is classified as an indoor camera and is available in white housing with support for surface mount and in-ceiling mount configurations. Dimensions are 153.5mm × 153.5mm × 71.3mm. A 5-year warranty is stated for the SRXF3-8360-I; no warranty term is specified for the Q450.
Which fits your VMS and analytics better?
Both cameras declare ONVIF compliance. The Q450 states general ONVIF compliance compatible with ONVIF-compliant VMS platforms; no specific ONVIF profile (S, T, or G) is listed in the provided specs. The SRXF3-8360-I specifies ONVIF Profile S and Profile T, giving integrators a more precise interoperability reference. Neither camera lists an ONVIF Profile G for on-board recording management.
The SRXF3-8360-I includes Pelco Smart Analytics with 8 behavior detection algorithms built into the edge device, along with microphone/audio support and local microSD storage. On-board memory is specified at 4GB RAM and 4GB Flash. The Q450 lists no edge analytics capability, no audio input or output, and no on-board storage in the provided specifications. Buyers requiring on-camera analytics or local redundant recording should note these are only confirmed features of the SRXF3-8360-I.
Which should you choose: the Q450 or the SRXF3-8360-I?
Our take: The SRXF3-8360-I is the stronger choice when the deployment is indoors, requires certified ONVIF Profile S/T interoperability, demands on-camera behavioral analytics, and needs a concrete low-light specification (0.10 lux) for audit or procurement documentation. Versus the Q450, it adds IK10 impact resistance, a 5-year warranty, 8 behavior-detection analytics, microSD edge storage, and audio support — none of which appear in the Q450's published specs. Conversely, the Q450's dual-lens 180° bullet form factor and H.265 compression support suit perimeter and outdoor-oriented coverage where bandwidth efficiency and weatherproof mounting matter, though the absence of a stated IP rating, operating temperature range, or lux value for the Q450 means those outdoor credentials cannot be confirmed from spec alone. Specify the SRXF3-8360-I for interior analytics deployments; evaluate the Q450 only after obtaining its full environmental ratings from ACTi.

Frequently Asked Questions
Which should you choose: the Q450 or the SRXF3-8360-I?
The SRXF3-8360-I is the stronger choice when the deployment is indoors, requires certified ONVIF Profile S/T interoperability, demands on-camera behavioral analytics, and needs a concrete low-light specification (0.10 lux) for audit or procurement documentation. Versus the Q450, it adds IK10 impact resistance, a 5-year warranty, 8 behavior-detection analytics, microSD edge storage, and audio support — none of which appear in the Q450's published specs. Conversely, the Q450's dual-lens 180° bullet form factor and H.265 compression support suit perimeter and outdoor-oriented coverage where bandwidth efficiency and weatherproof mounting matter, though the absence of a stated IP rating, operating temperature range, or lux value for the Q450 means those outdoor credentials cannot be confirmed from spec alone. Specify the SRXF3-8360-I for interior analytics deployments; evaluate the Q450 only after obtaining its full environmental ratings from ACTi.
Is the ACTi Q450 or Pelco SRXF3-8360-I better for low-light performance?
Based on the provided specifications, only the SRXF3-8360-I has a stated minimum illumination figure: 0.10 lux. The Q450 lists IR and Day/Night capability but provides no lux value, so a direct numerical low-light comparison cannot be made from spec alone. If a documented lux rating is required for your project, the SRXF3-8360-I is the only option with that data on record.
Can both cameras integrate with third-party VMS platforms?
Both cameras declare ONVIF compliance. The SRXF3-8360-I specifies ONVIF Profile S and Profile T, which defines the level of interoperability more precisely. The Q450 states general ONVIF compliance without specifying a profile. Installers working with VMS platforms that require a specific ONVIF profile declaration should confirm the Q450's profile level directly with ACTi before specifying it.
Which camera requires less infrastructure — standard PoE or PoE+?
The ACTi Q450 operates on standard PoE at 13W, compatible with 802.3af switches. The Pelco SRXF3-8360-I requires PoE+ (802.3at, Class 3), which draws up to 30W and necessitates a PoE+ capable switch or midspan injector. If your existing switch infrastructure is 802.3af only, the Q450 avoids the need for infrastructure upgrades; the SRXF3-8360-I would require either switch replacement or per-port PoE+ injectors.
