ACTi Z79 vs Speco Technologies O4LT2: Specification Comparison
Both the ACTi Z79 and Speco Technologies O4LT2 are 4MP outdoor turret cameras designed for fixed-view perimeter and entrance surveillance. They occupy the same resolution class and share a turret form factor, making them direct cross-shop candidates for installers evaluating PoE IP cameras in the sub-$300 segment. This comparison examines imaging specifications, installation and environmental ratings, and integration capabilities based solely on the published specifications for each model.

How do the imaging specs compare?
The ACTi Z79 is specified at 4MP with a 2.8mm fixed lens at F2.0. It employs IR-based low-light technology described as adaptive IR, but no sensor size, minimum illumination figure, or IR range in meters is provided in the available specifications. WDR is listed as supported. Compression is H.265 and H.264 dual-stream. No maximum frame rate is stated in the provided spec data.
The Speco O4LT2 is specified at 4MP with a maximum resolution of 2688x1520 at 30fps, using a 1/1.79-inch CMOS sensor and a 2.8mm fixed lens with approximately 110° horizontal field of view. Night vision is achieved via white-light intensifier technology rather than infrared illumination — a meaningful distinction for color night imaging versus monochrome IR. WDR is listed. Compression covers H.265, H.264, and MJPEG. The O4LT2 also documents day/night operation. No minimum illumination figure is provided for either camera.
What about installation and environment?
The ACTi Z79 carries IP68 and IK10 ratings. IP68 indicates protection against continuous submersion beyond 1 meter — a higher ingress rating than IP67. IK10 is the maximum impact resistance rating under IEC 62262, denoting resistance to 20-joule impacts. The housing is described as metal. Power is PoE 802.3af with a maximum draw of 13W. Operating temperature is specified as -40°C to 60°C (-40°F to 140°F). Mounting options listed are wall and ceiling. No weight or dimensions are provided in the available specs.
The Speco O4LT2 carries an IP67 rating, which covers temporary immersion up to 1 meter for 30 minutes, but no IK impact resistance rating is stated. Power input is PoE or DC 12V — dual-input flexibility the Z79 does not list. Power consumption is 5.5W, meaningfully lower than the Z79's 13W maximum, which can matter on switch budget-constrained installations. Operating temperature is -40°F to 140°F (-40°C to 60°C), matching the Z79's range. The O4LT2 weighs 1.0 lb; no weight is specified for the Z79. Housing color is white. A 3-year warranty is documented for the O4LT2; no warranty term is provided in the Z79 spec data.
Which fits your VMS and analytics better?
The ACTi Z79 lists ONVIF compliance (Profile not specified in provided data) and is noted as compatible with VMS platforms via ONVIF. On-board storage via MicroSD is supported. Audio is one-way via built-in microphone. No edge analytics beyond motion are stated in the provided specifications.
The Speco O4LT2 specifies ONVIF Profile G compliance, which adds on-board recording and retrieval capabilities beyond basic ONVIF interoperability. Edge analytics are explicitly documented: motion detection, line crossing, and vehicle detection — reducing server-side processing load and enabling real-time alerting without VMS analytics licenses. Audio is two-way, which the Z79 does not support based on provided specs. No on-board MicroSD or edge storage is listed in the O4LT2 specifications.
Which should you choose: the Z79 or the O4LT2?
Our take: The O4LT2 is the stronger choice when edge analytics, two-way audio, and dual-power flexibility are priorities; the Z79 is the stronger choice when maximum physical hardening is required. Concretely: the Z79's IP68 rating exceeds the O4LT2's IP67, and its IK10 impact rating has no equivalent stated for the O4LT2 — relevant for exposed or vandal-prone mounting locations. Conversely, the O4LT2 draws only 5.5W versus the Z79's 13W maximum, preserving switch power budget on dense deployments. The O4LT2 also adds three documented edge analytics functions, ONVIF Profile G, and two-way audio — none of which are confirmed for the Z79 in available specs. The O4LT2 further documents a 3-year warranty; no warranty term appears in the Z79 data. Choose the Z79 for demanding physical environments; choose the O4LT2 where analytics, audio, and power efficiency drive the decision.

Frequently Asked Questions
Which should you choose: the Z79 or the O4LT2?
The O4LT2 is the stronger choice when edge analytics, two-way audio, and dual-power flexibility are priorities; the Z79 is the stronger choice when maximum physical hardening is required. Concretely: the Z79's IP68 rating exceeds the O4LT2's IP67, and its IK10 impact rating has no equivalent stated for the O4LT2 — relevant for exposed or vandal-prone mounting locations. Conversely, the O4LT2 draws only 5.5W versus the Z79's 13W maximum, preserving switch power budget on dense deployments. The O4LT2 also adds three documented edge analytics functions, ONVIF Profile G, and two-way audio — none of which are confirmed for the Z79 in available specs. The O4LT2 further documents a 3-year warranty; no warranty term appears in the Z79 data. Choose the Z79 for demanding physical environments; choose the O4LT2 where analytics, audio, and power efficiency drive the decision.
Is the Z79 or O4LT2 better for low-light performance?
The two cameras use different technologies: the Z79 uses adaptive IR illumination for monochrome night imaging, while the O4LT2 uses white-light intensifier technology, which produces color night images. Neither camera's minimum illumination figure is documented in the available specifications, so a direct lux-level comparison cannot be made from the provided data. The choice depends on whether color or range is the priority — white light provides color detail at close range; IR typically reaches farther in complete darkness.
Can the O4LT2 run analytics without a VMS license?
Yes, based on the provided specifications. The O4LT2 lists motion detection, line crossing, and vehicle detection as on-camera edge analytics, meaning these functions execute on the camera itself and do not require server-side VMS analytics modules. The Z79 does not document equivalent edge analytics in its available specifications.
Which camera is better suited for a location prone to vandalism or physical impact?
The ACTi Z79 is the documented choice for impact resistance. It carries an IK10 rating, the highest level under IEC 62262, indicating resistance to 20-joule impacts, along with a metal housing. The Speco O4LT2 does not list an IK impact resistance rating in its available specifications, so no equivalent comparison can be made on that metric.
