ACTi Q450 vs Pelco IMF82-1I: Specification Comparison
Both the ACTi Q450 and Pelco IMF82-1I are 8MP fixed-lens cameras targeting wide-area coverage with a single unit, making them legitimate cross-shop candidates for installers seeking to reduce camera count on a run. The Q450 uses a dual-imager panoramic bullet form factor delivering 180° horizontal coverage, while the IMF82-1I is a ceiling-mount fisheye offering both 180° and 360° dewarped views. This comparison covers imaging performance, installation requirements, and VMS/analytics integration based strictly on published specifications.

How do the imaging specs compare?
Both cameras share an 8MP resolution ceiling, but their optical architectures differ substantially. The ACTi Q450 uses two fixed 2.8mm lenses to produce a 180° horizontal field of view, with Adaptive IR illumination for active night vision in complete darkness — no minimum illumination figure is published in the provided spec sheet. The Pelco IMF82-1I uses a single 2.7mm f/2.5 lens (with a separately noted focal length of 1.4mm in the spec data) to achieve either 180° or 360° fisheye coverage at a maximum resolution of 3264×2448, with a published minimum illumination of 0.10 lux and no integrated IR illuminator.
On WDR, both cameras list WDR support; the Pelco IMF82-1I specifies a dynamic range of up to 83dB, while the ACTi Q450 does not publish a dB figure. Frame rate is only specified for the IMF82-1I at 12.5 fps at full resolution — the Q450 provides no frame rate figure in the supplied specs. The IMF82-1I's lack of IR means it depends entirely on ambient light for night vision, where its 0.10 lux sensitivity is the sole low-light safeguard; the Q450's Adaptive IR provides an active illumination advantage in zero-lux environments.
What about installation and environment?
The ACTi Q450 is PoE-powered at 13W, placing it within standard 802.3af (Class 3, max 15.4W) budget, which simplifies switch planning. No IP or IK rating is published for the Q450, and no operating temperature range is specified in the provided data — installers must consult the full datasheet before deploying in harsh or outdoor environments. Its panoramic bullet form factor implies wall or pole mounting oriented for horizontal sweeps.
The Pelco IMF82-1I requires PoE+ (802.3at, Class 3) for operation, demanding a PoE+ capable switch or injector. It carries an IP52 rating (limited dust ingress protection, protected against vertically dripping water) and an IK10 impact rating, confirming resistance to physical vandalism. Its operating temperature range is -10°C to +60°C, and its Environment Rating is listed as Indoor. The fisheye form factor supports ceiling, wall, pole, pendant, and corner mounting. Dimensions are published at 6" × 6" × 2.4". A 5-year warranty is specified for the IMF82-1I; no warranty term is stated for the Q450.
Which fits your VMS and analytics better?
The ACTi Q450 declares ONVIF compliance without specifying a Profile (S, T, or G), and is described as compatible with ONVIF-compliant VMS platforms broadly. No edge analytics, on-board storage, or audio capability is listed in the provided specs. The Pelco IMF82-1I holds ONVIF Profile S, Profile T, and Profile G certifications — Profile G specifically covers on-board recording, aligning with its microSD local storage support. Audio input (microphone supported) is also specified on the IMF82-1I.
On analytics, the IMF82-1I includes Pelco Smart Analytics with 8 on-camera behavior detection capabilities (object detection, loitering, line crossing, and others). The Q450 lists no edge analytics in the provided specification data. For buyers whose VMS lacks server-side analytics or who need edge-autonomous detection, the IMF82-1I's on-camera intelligence is a concrete differentiator. For buyers running a Pelco VMS ecosystem, Profile G compatibility and integrated analytics will reduce server-side load. ACTi's Q450 will suit any ONVIF-compliant platform but contributes no analytics at the edge based on the specs provided.
Which should you choose: the Q450 or the IMF82-1I?
Our take: The IMF82-1I is the stronger choice when the deployment requires ceiling-mount 360° coverage, on-camera analytics, on-board storage, and a verified vandal rating — it delivers 8 on-camera behavior detections, IK10 impact resistance, microSD local storage, ONVIF Profiles S/T/G, and a 0.10 lux low-light floor in a single unit with a 5-year warranty. The Q450 is the stronger choice when active IR illumination is non-negotiable for zero-lux perimeter coverage: its Adaptive IR provides light the IMF82-1I entirely lacks. Power budget is a practical delta — the Q450's 13W fits standard 802.3af switches, while the IMF82-1I demands PoE+ infrastructure. If the site already runs PoE+ switches and needs edge-autonomous detection or 360° dewarped views indoors, the IMF82-1I is the more capable unit; if the perimeter runs dark and existing switches are 802.3af-only, the Q450's IR and lower power draw are operationally decisive.

Frequently Asked Questions
Which should you choose: the Q450 or the IMF82-1I?
The IMF82-1I is the stronger choice when the deployment requires ceiling-mount 360° coverage, on-camera analytics, on-board storage, and a verified vandal rating — it delivers 8 on-camera behavior detections, IK10 impact resistance, microSD local storage, ONVIF Profiles S/T/G, and a 0.10 lux low-light floor in a single unit with a 5-year warranty. The Q450 is the stronger choice when active IR illumination is non-negotiable for zero-lux perimeter coverage: its Adaptive IR provides light the IMF82-1I entirely lacks. Power budget is a practical delta — the Q450's 13W fits standard 802.3af switches, while the IMF82-1I demands PoE+ infrastructure. If the site already runs PoE+ switches and needs edge-autonomous detection or 360° dewarped views indoors, the IMF82-1I is the more capable unit; if the perimeter runs dark and existing switches are 802.3af-only, the Q450's IR and lower power draw are operationally decisive.
Is the Q450 or IMF82-1I better for low-light and nighttime use?
The ACTi Q450 is the stronger low-light option for zero-lux environments because it includes Adaptive IR illumination — active IR means the camera generates its own light in complete darkness. The Pelco IMF82-1I has no integrated IR illuminator; it relies solely on ambient light, where its published minimum illumination is 0.10 lux. In environments with some residual lighting (parking structures, lit lobbies), the IMF82-1I's 0.10 lux sensitivity may be adequate, but in true darkness the Q450's IR provides coverage the IMF82-1I cannot match without external lighting.
Which camera needs less from my switch infrastructure — the Q450 or the IMF82-1I?
The ACTi Q450 draws 13W and is powered by standard PoE (802.3af), which is supported by the vast majority of managed switches in the field. The Pelco IMF82-1I requires PoE+ (802.3at), which delivers up to 30W but is only available on PoE+-capable switches or injectors. If your existing switch infrastructure is 802.3af-only, the Q450 installs without hardware changes; deploying the IMF82-1I will require confirming or upgrading switch port capability.
Does either camera support on-camera analytics or local video storage without a server?
Yes — but only the Pelco IMF82-1I. It includes Pelco Smart Analytics with 8 on-camera behavior detections (object detection, loitering, line crossing, and others) and supports microSD on-board storage, with ONVIF Profile G compliance enabling standardized local recording. The ACTi Q450 lists no edge analytics and no on-board storage in the provided specification data. If autonomous edge detection or server-independent recording is a requirement, the IMF82-1I is the only option between the two.
