ACTi A818 vs i-PRO X25700-V2LN: Specification Comparison
Both the ACTi A818 and i-PRO WV-X25700-V2LN are 6MP outdoor fixed dome cameras targeting perimeter and general surveillance applications where varifocal optics, IR night vision, and edge analytics matter. The A818 offers a wider 5x optical zoom range (2.7–13.5 mm) with a declared 150 dB WDR figure, while the X25700-V2LN pairs a higher-resolution 1/1.8-inch sensor with an Ambarella CV52 SoC for deeper AI analytics and a 132 dB Super Dynamic range. This comparison covers imaging, installation, and integration trade-offs drawn strictly from published specifications.

How do the imaging specs compare?
The ACTi A818 uses a 1/2.7-inch CMOS sensor and a 2.7–13.5 mm (5x optical zoom) varifocal lens, giving it a longer reach at the telephoto end and a wider field at the wide end. Its declared WDR is 150 dB (marketed as Extreme WDR), and minimum illumination is 0.01 lux in color and 0 lux with its 850 nm IR LEDs active at an 85 m throw distance. Maximum frame rates are 30 fps at 1920×1080 and 25 fps at 2688×1520. The A818 resolves to a maximum of 2592×1944 pixels (approximately 5 MP native capture), outputting at up to 6 MP equivalent.
The i-PRO WV-X25700-V2LN uses a larger 1/1.8-inch CMOS sensor and records natively at 3840×2160 (4K UHD), outputting full 30 fps at that resolution. Its motorized varifocal lens spans 4.3–8.6 mm (2x optical zoom), a considerably narrower zoom ratio than the A818's 5x. WDR is rated at a maximum of 132 dB with Super Dynamic enabled at level 31. Minimum illumination is 0.03 lux (B/W, 50 IRE, F1.5, 1/30 s), and the built-in IR illuminator reaches 70 m. The larger sensor, wider aperture at F1.5, and built-in gyro-based image stabilizer are distinct imaging advantages, but the A818's 5x zoom range and 85 m IR throw address longer-distance identification needs.
What about installation and environment?
The ACTi A818 is rated IP68 and NEMA 4X, meaning it is fully submersion-rated and suitable for wash-down environments, along with an IK10 vandal resistance rating (50 J per IEC 60068-2-75 implied by IK10). It operates from −30 °C to +60 °C and weighs 1,046 g (2.31 lb). Power is accepted via DC 12 V or PoE Class 3 (IEEE 802.3af), with a maximum draw of 13 W. The pigtail cable terminates in RJ-45. Mounting options listed in specs include wall, pole, corner, and rack via accessories.
The i-PRO WV-X25700-V2LN carries IP66/IP67 and NEMA 4X ratings—one step below the A818's IP68—and also achieves IK10 (50 J, IEC 60068-2-75). Its operating temperature range is broader: −40 °C to +55 °C (PoE-on cold limit −30 °C). It accepts DC 12 V (1.2 A) or PoE+ at 14 W (PoE Class 4). The camera is specified for wind resistance up to 40 m/s (~89 mph) and weighs approximately 1.1 kg (2.43 lb). Dimensions are ø154 mm × 105 mm (H). The A818's IP68 rating offers a meaningful advantage in flood-prone or high-pressure wash-down installations; the X25700-V2LN's −40 °C lower cold limit is an advantage in extreme-cold deployments.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profile S, G, T, and M, ensuring broad VMS compatibility. The ACTi A818 includes Video Motion Detection, People Counting, Smoke Detection, Face Detection, and Tampering Detection as listed edge analytics. It supports H.265, H.264, and MJPEG compression. Audio support includes 2-way with mic-in, line-in, and line-out. On-board storage capability is not stated in the provided A818 specifications. The A818 holds Taiwan IoT Cybersecurity Certification Level 1. No signed firmware or secure boot claims are listed in the provided A818 specs.
The i-PRO WV-X25700-V2LN runs on an Ambarella CV52 SoC and adds AI-class analytics: AI Motion Detection, Face Detection, Vehicle Detection, Audio Detection, and AI Sound Classification (gunshot, yell, vehicle horn, glass break). It supports up to 4 VMD areas, Scene Change Detection, 8 privacy zones, and VIQS. On-board storage accepts microSD/SDHC/SDXC up to 512 GB. Audio is full duplex (3.5 mm stereo I/O). It specifies signed firmware, secure boot, HTTPS encryption, and SNMPv3 among supported protocols. Safety certifications include UL 62368-1, c-UL, CE, and IEC 62368-1. EMC compliance covers FCC Part 15 Class A and EN55032 Class A. The X25700-V2LN's broader AI analytics stack, on-board storage, and deeper cybersecurity certifications make it the stronger fit for enterprise VMS environments requiring edge intelligence and local redundancy.
Which should you choose: the A818 or the X25700-V2LN?
Our take: The A818 is the stronger choice when installation priority is extended zoom reach, wash-down-rated ingress protection, or cost-sensitive deployments where a 5x optical zoom (2.7–13.5 mm vs. the X25700-V2LN's 2x, 4.3–8.6 mm) is required to cover long corridors or perimeter fences from a single camera. Three concrete spec deltas favor each: the A818 delivers 85 m IR range vs. 70 m, IP68 vs. IP67, and 150 dB WDR vs. 132 dB. Conversely, the X25700-V2LN wins on sensor size (1/1.8 inch vs. 1/2.7 inch), native 4K resolution (3840×2160 vs. 2688×1520 max), AI Sound Classification (gunshot/glass break), on-board storage up to 512 GB (not specified on A818), and a lower cold-start temperature of −40 °C vs. −30 °C. Choose the X25700-V2LN where AI analytics depth, local storage redundancy, or arctic-range operation is required.

Frequently Asked Questions
Which should you choose: the A818 or the X25700-V2LN?
The A818 is the stronger choice when installation priority is extended zoom reach, wash-down-rated ingress protection, or cost-sensitive deployments where a 5x optical zoom (2.7–13.5 mm vs. the X25700-V2LN's 2x, 4.3–8.6 mm) is required to cover long corridors or perimeter fences from a single camera. Three concrete spec deltas favor each: the A818 delivers 85 m IR range vs. 70 m, IP68 vs. IP67, and 150 dB WDR vs. 132 dB. Conversely, the X25700-V2LN wins on sensor size (1/1.8 inch vs. 1/2.7 inch), native 4K resolution (3840×2160 vs. 2688×1520 max), AI Sound Classification (gunshot/glass break), on-board storage up to 512 GB (not specified on A818), and a lower cold-start temperature of −40 °C vs. −30 °C. Choose the X25700-V2LN where AI analytics depth, local storage redundancy, or arctic-range operation is required.
Is the A818 or WV-X25700-V2LN better for low-light performance?
On specified numbers, the A818 achieves 0.01 lux in color and 0 lux (IR on) with an 85 m IR throw at 850 nm. The X25700-V2LN is rated at 0.03 lux (B/W, 50 IRE, F1.5, 1/30 s) with a 70 m IR range. The A818's lower lux figure and longer IR throw favor it in large unlit areas; however, the X25700-V2LN's larger 1/1.8-inch sensor and F1.5 maximum aperture provide more photon-gathering capability, which is not fully captured by lux figures alone. Buyers should evaluate both figures together rather than relying on either spec in isolation.
Which camera is better suited for extreme outdoor environments?
The A818 holds an IP68 rating (full submersion) and NEMA 4X, making it the better choice for flood-prone or pressure wash-down sites. The X25700-V2LN is rated IP66/IP67 and NEMA 4X, plus adds a specified wind resistance of up to 40 m/s and a lower operating temperature floor of −40 °C versus the A818's −30 °C. For cold-climate or high-wind deployments, the X25700-V2LN has the edge; for submersion-risk environments, the A818's IP68 is the differentiator.
Does either camera support on-board edge storage?
The i-PRO WV-X25700-V2LN specifies microSD/SDHC/SDXC support up to 512 GB for local edge recording. The provided ACTi A818 specifications do not include any reference to on-board storage or SD card support. Buyers who require local redundancy or failover recording without a continuous NVR connection should verify A818 storage capability directly with ACTi before specifying it in that role.
