ACTi B511A vs i-PRO X22700-V2L: Specification Comparison
Both the ACTi B511A and i-PRO WV-X22700-V2L are 12MP indoor fixed cameras, placing them in the same resolution class for cross-shopping purposes. However, their form factors differ fundamentally: the B511A is a fisheye hemispheric dome delivering a 198.5° panoramic field of view from a single mount point, while the X22700-V2L is a conventional dome with a motorized varifocal lens. Buyers evaluating these units are typically choosing between wide-area panoramic coverage with edge counting analytics versus directional 4K coverage with AI-driven object classification and extended IR reach.

How do the imaging specs compare?
Both cameras deliver 12MP resolution, but their optical designs serve fundamentally different coverage strategies. The B511A uses a fixed 1.65mm fisheye lens on a 1/1.7" sensor to produce a 198.5° hemispheric view, capturing an entire room from a ceiling mount at up to 30 fps at 1920×1080 or 18 fps at 4000×3000. Its WDR is rated at 130 dB and minimum illumination reaches 0.003 lux (color, F2.8), with IR illumination extending to 20 meters at 850nm. The X22700-V2L uses a motorized varifocal 4.3–8.6mm lens (2.0x optical zoom) on an approximately 1/1.8" CMOS sensor, delivering a 52°–101° horizontal field of view and 30 fps at 12MP. Its Super Dynamic WDR is rated at a maximum 132 dB (at level 31), and minimum illumination is 0.03 lux in B&W with IR LED active — ten times higher than the B511A's rated figure.
IR reach is a significant differentiator: the X22700-V2L extends to 70 meters (230 ft), versus the B511A's 20-meter IR range. The X22700-V2L also adds an image stabilizer using a gyro sensor (at 30 fps), motorized focus, and an extra digital zoom up to 12x at reduced resolution (640×360). The B511A's fisheye optic inherently limits per-pixel detail at distance but maximizes spatial coverage per mount point. The X22700-V2L includes fog compensation and adaptive black stretch controls not listed in the B511A spec sheet.
What about installation and environment?
The ACTi B511A is rated for indoor use only; no IP ingress protection rating is listed in the provided specifications. The i-PRO X22700-V2L carries an IP67 rating (dust-tight, temporary immersion) and IK10 impact resistance per IEC 62262, giving it a significantly higher mechanical and environmental protection level despite also being designated for indoor use. Neither unit is spec'd for outdoor deployment based on the provided data.
Both cameras operate over the same ambient temperature range: -10°C to +50°C. The B511A is powered by PoE Class 3 (IEEE 802.3af, up to approximately 15.4W) or DC 12V; its spec sheet lists PoE+ (802.3at) Class 3 in one field while referencing IEEE 802.3af in another — buyers should confirm the exact draw before switch port planning. The X22700-V2L is explicitly rated PoE+ (802.3at) at 14.0W (PoE Class 4) or DC 12V at 14.2W. The B511A weighs approximately 446g (0.983 lb) and supports wall, pole, pendant, corner, and rack mounting. The X22700-V2L weighs approximately 820g (1.9 lbs); its listed mount types in the provided spec fields are pole, corner, and rack — pendant and wall mount options are not confirmed in the supplied data. The X22700-V2L's aluminum/PC housing and IK10 rating make it more robust for high-traffic or vandal-risk indoor environments.
Which fits your VMS and analytics better?
Both cameras support ONVIF, but with different profile coverage. The B511A is listed as compliant with ONVIF Profiles S, G, T, Q, and M (with Profile M noted as pending future firmware). The X22700-V2L supports ONVIF Profiles G, S, T, and M. The B511A supports H.264 (Baseline, Main, High profile) and MJPEG; H.265 is not listed in its spec sheet. The X22700-V2L supports H.265, H.264 (CBR/VBR/frame-rate modes), and MJPEG — H.265 reduces bandwidth and storage consumption materially at 12MP streams. The X22700-V2L also specifies an extensive protocol list including SRTP, MQTT, SFTP, SNMPv1/v2/v3, and FIPS 140-2 Level 3 security; these are not referenced in the B511A spec sheet.
Edge analytics differ in depth. The B511A provides VMD and People Counting at the edge. The X22700-V2L delivers AI Video Motion Detection, Face Detection, People Detection, Vehicle Detection, Scene Change Detection, Audio Detection, and AI Sound Classification (gunshot, yell, vehicle horn, glass break) — a substantially broader AI analytics suite built on an Ambarella CV52 SoC. On audio, the B511A includes a built-in microphone, mic-in, line-in, and line-out; the X22700-V2L provides a 3.5mm stereo audio input jack and a 3.5mm stereo audio output, plus 3 alarm inputs, 1 alarm output, and 1 AUX output — no built-in microphone is listed in the provided spec sheet. Local edge storage is supported only on the X22700-V2L (microSD/SDHC/SDXC up to 512GB); no onboard storage is listed for the B511A. The X22700-V2L also carries a stated 5-year warranty; warranty duration is not specified in the B511A's provided spec sheet.
Which should you choose: the B511A or the X22700-V2L?
Our take: The B511A is the stronger choice when a single ceiling mount must cover an entire open room with panoramic situational awareness and lightweight People Counting at the edge — its 198.5° fisheye view eliminates blind spots that a conventional dome cannot match from one install point. The X22700-V2L is the stronger choice when directional detail, AI classification depth, or low-light range are priorities: its IR reach is 70m versus the B511A's 20m, its minimum illumination is 0.03 lux versus the B511A's 0.003 lux (B511A is actually more sensitive here), its WDR edges to 132 dB versus 130 dB, and its AI analytics (face, vehicle, sound classification) go well beyond the B511A's VMD and People Counting. Add H.265 compression, FIPS 140-2 Level 3 security, IK10 impact resistance, IP67 sealing, onboard microSD storage up to 512GB, and a stated 5-year warranty — none of which are listed for the B511A — and the X22700-V2L fits enterprise VMS environments with stricter cybersecurity and resilience requirements. Budget-conscious single-room deployments with a PoE switch and a basic ONVIF VMS favor the B511A's panoramic efficiency.

Frequently Asked Questions
Which should you choose: the B511A or the X22700-V2L?
The B511A is the stronger choice when a single ceiling mount must cover an entire open room with panoramic situational awareness and lightweight People Counting at the edge — its 198.5° fisheye view eliminates blind spots that a conventional dome cannot match from one install point. The X22700-V2L is the stronger choice when directional detail, AI classification depth, or low-light range are priorities: its IR reach is 70m versus the B511A's 20m, its minimum illumination is 0.03 lux versus the B511A's 0.003 lux (B511A is actually more sensitive here), its WDR edges to 132 dB versus 130 dB, and its AI analytics (face, vehicle, sound classification) go well beyond the B511A's VMD and People Counting. Add H.265 compression, FIPS 140-2 Level 3 security, IK10 impact resistance, IP67 sealing, onboard microSD storage up to 512GB, and a stated 5-year warranty — none of which are listed for the B511A — and the X22700-V2L fits enterprise VMS environments with stricter cybersecurity and resilience requirements. Budget-conscious single-room deployments with a PoE switch and a basic ONVIF VMS favor the B511A's panoramic efficiency.
Is the B511A or X22700-V2L better for low-light performance?
The B511A lists a minimum illumination of 0.003 lux (color, F2.8) versus the X22700-V2L's 0.03 lux (B&W with IR LED) — the B511A's sensor sensitivity figure is ten times lower, indicating better performance in near-darkness before IR activates. However, the X22700-V2L's IR illumination extends to 70 meters compared to the B511A's 20 meters, so in large or long spaces where active IR throw matters more than passive sensitivity, the X22700-V2L covers significantly more ground.
Can either camera record locally without a VMS or NVR?
Only the i-PRO X22700-V2L supports local edge storage: it accepts microSD, microSDHC, and microSDXC cards up to 512GB (64GB–512GB for SDXC). Local SD recording is also listed as an alarm action. The ACTi B511A spec sheet does not list any onboard storage capability; it also supports ONVIF Profile G (which enables NVR-based edge recording) but does not appear to offer card-based local storage.
Which camera is better suited for a high-security or enterprise IT environment?
The i-PRO X22700-V2L is better suited for enterprise and high-security deployments. It specifies FIPS 140-2 Level 3 cryptographic compliance, HTTPS encryption, signed firmware, and secure boot — features that address common IT security policy requirements. Its protocol support includes SNMPv1/v2/v3, SRTP, and MQTT. The ACTi B511A lists HTTPS-capable ONVIF profiles and standard FCC/CE/UL certifications, but FIPS compliance, signed firmware, and secure boot are not referenced in its provided spec sheet.
