ACTi B419 vs ACTi B43: Specification Comparison
Both the ACTi B419 and ACTi B43 are 5MP outdoor bullet cameras with motorized zoom lenses and video analytics, positioned for perimeter and wide-area surveillance. The comparison covers two distinct zoom ranges—10x on the B419 versus 30x on the B43—along with differences in power delivery, audio capability, environmental ratings, and onboard storage. Buyers choosing between these two are trading off zoom reach, PoE class requirements, feature depth, and integration flexibility across VMS platforms.

How do the imaging specs compare?
Both cameras share a 5MP maximum resolution and deliver 30 fps, but they diverge significantly in lens range. The B419 uses a 4.7–47mm motorized lens providing 10x optical zoom, while the B43 extends to 4.5–135mm for 30x optical zoom—triple the reach. The B419 specifies a 1/2.9" sensor and achieves a minimum illumination of 0.003 lux in color mode (F1.6) and 0 lux with IR active; the B43 provides no equivalent minimum illumination figure in the supplied specs. The B419 also specifies its IR wavelength as 940nm (invisible) with an IR range of 60m, while the B43 lists IR as adaptive Day/Night only—no wavelength or range value is provided. The B419 notes the B43's max FPS as 30 fps at 1080p, whereas the B419 achieves 30 fps at full 5MP (2592×1944).
WDR is listed at a quantified 120 dB for the B419. The B43 lists WDR without a dB value. H.265 and H.264 compression are present on both; the B419 adds MJPEG and specifies H.264 profile variants (Baseline, Main, High). The B43 does not specify H.264 profiles or MJPEG support in the provided specs.
What about installation and environment?
Both cameras carry IP66 and IK10 ratings, confirming dust-tight, jet-water-resistant, and impact-resistant housings. The B419 adds NEMA 4X certification, providing tested resistance to corrosion and windblown dust per that standard; the B43 does not list NEMA 4X. The B419 specifies an operating temperature range of −40°C to +60°C; no operating temperature range is provided for the B43 in the supplied specs.
Power requirements differ materially. The B419 requires PoE++ (802.3bt) for full operation, with DC 12V also listed; the B43 operates on PoE 802.3af—the lowest PoE class—making it compatible with a broader range of existing switches and injectors without upgrades. Mount options are wider on the B419 (Wall, Ceiling, Pole, Rack) versus Wall and Pole on the B43. Both ship in bullet form factor. The B419 weighs 2,134g (4.7 lb); no weight is provided for the B43.
Which fits your VMS and analytics better?
The B419 specifies ONVIF conformance to Profiles S, G, T, and M, and additionally supports Visca, Pelco-D, and Pelco-P PTZ control protocols. The B43 is listed as ONVIF-compliant without specifying which profiles are supported. Both confirm ONVIF compatibility, but the B419's multi-profile and legacy PTZ protocol support broadens its compatibility with older or mixed-protocol VMS environments.
Edge analytics are more extensive on the B419: VMD, people counting, and smoke detection are specified. The B43 lists motion detection, line crossing, and intrusion alerts—different capability sets that may favor different use cases. Audio is a clear differentiator: the B419 supports two-way audio with a built-in microphone, mic-in, line-in, and line-out; the B43 provides only a built-in microphone with no line inputs or outputs listed. The B43 includes onboard MicroSDHC/MicroSDXC storage; the B419 does not list any onboard storage in the supplied specs.
Which should you choose: the B419 or the B43?
Our take: The B419 is the stronger choice when you need forensic-grade cold-weather deployment, verified VMS protocol breadth, and two-way audio in a hardened housing. Key spec deltas: the B419's WDR is quantified at 120 dB versus an unquantified WDR on the B43; the B419 operates to a specified −40°C floor while the B43 lists no temperature range; and the B419 carries NEMA 4X certification absent on the B43. Conversely, the B43's 30x optical zoom (4.5–135mm) triples the B419's 10x reach, making it the practical choice for long-range identification at fixed mounts. The B43 also runs on 802.3af—the lowest PoE class—avoiding switch or injector upgrades, and adds onboard MicroSD storage. Choose the B419 for harsh-environment, analytics-rich, audio-capable installations on PoE++ infrastructure; choose the B43 where extended zoom range, storage redundancy, and standard PoE compatibility are the primary drivers.

Frequently Asked Questions
Which should you choose: the B419 or the B43?
The B419 is the stronger choice when you need forensic-grade cold-weather deployment, verified VMS protocol breadth, and two-way audio in a hardened housing. Key spec deltas: the B419's WDR is quantified at 120 dB versus an unquantified WDR on the B43; the B419 operates to a specified −40°C floor while the B43 lists no temperature range; and the B419 carries NEMA 4X certification absent on the B43. Conversely, the B43's 30x optical zoom (4.5–135mm) triples the B419's 10x reach, making it the practical choice for long-range identification at fixed mounts. The B43 also runs on 802.3af—the lowest PoE class—avoiding switch or injector upgrades, and adds onboard MicroSD storage. Choose the B419 for harsh-environment, analytics-rich, audio-capable installations on PoE++ infrastructure; choose the B43 where extended zoom range, storage redundancy, and standard PoE compatibility are the primary drivers.
Is the B419 or B43 better for low-light performance?
Based on the provided specs, the B419 is better documented for low light: it specifies a minimum illumination of 0.003 lux in color mode and 0 lux with IR active, uses a 940nm invisible IR emitter with a 60m IR range. The B43 lists IR as adaptive Day/Night but provides no minimum illumination value, no IR wavelength, and no IR range figure in its specifications.
Which camera needs less from my existing switch infrastructure?
The B43 requires only PoE 802.3af—the most widely supported PoE class—meaning most existing managed switches and injectors will power it without upgrades. The B419 requires PoE++ (802.3bt), which delivers higher wattage but demands 802.3bt-capable switches or a dedicated injector. If your infrastructure is not already PoE++ capable, the B43 imposes no additional switch investment.
Does either camera support on-board storage for edge recording?
Yes, but only the B43 in the provided specifications: it lists MicroSDHC and MicroSDXC slot support for local recording. The B419 specifications do not mention onboard storage of any kind. If edge recording without NVR dependency is a requirement, the B43 is the only option supported by the available spec data.
