ACTi A23 vs Geovision BX1500V-301U: Specification Comparison
Both the ACTi A23 and Geovision BX1500V-301U are wired IP box cameras targeting indoor/outdoor surveillance installations where a varifocal lens and PoE simplify deployment. They share the same form factor, 802.3af PoE power budget, ONVIF compliance, and Day/Night operation — making them direct cross-shop candidates for installers specifying a budget-to-mid-tier box camera. The key differentiator is resolution: the A23 delivers 3 MP versus the BX1500V-301U's 1.3 MP, which drives most of the other trade-off discussion below.

How do the imaging specs compare?
The ACTi A23 captures at 3 MP, delivering noticeably more pixel density than the Geovision BX1500V-301U's 1.3 MP sensor. That resolution gap — roughly 2.3× more pixels — translates directly into wider coverage zones or tighter digital zoom headroom before forensic detail degrades. The A23 specifies a maximum frame rate of 30 fps at 1080p; the BX1500V-301U does not list a rated frame rate in the provided specifications. Both cameras feature varifocal lenses: the A23 provides a precisely specified 2.8–12 mm range at f/1.4–2.8, while the Geovision unit lists 'Varifocal F2.8-1' without a documented long-end focal length or full aperture range, limiting direct optical comparison.
For wide dynamic range, the A23 is rated Extreme WDR, a higher performance tier than the standard WDR noted for the BX1500V-301U — relevant in lobbies, parking garage entrances, or any scene mixing bright exterior light with shadowed interiors. The Geovision unit's specified advantage is Super Low Lux sensitivity, a low-light descriptor absent from the A23's provided specifications; neither camera lists a quantified minimum illumination value in lux, so a direct numerical low-light comparison cannot be made from the supplied data. Both cameras operate in Day/Night mode.
What about installation and environment?
Both cameras draw 13 W maximum and are powered via 802.3af PoE over standard Cat5e/Cat6 cabling with an RJ-45 connector, so they fit identically into existing PoE switch budgets without requiring midspans or local power drops. Neither camera's provided specifications include an IP ingress-protection rating, IK impact rating, or operating temperature range, meaning installers must consult full datasheets before specifying either unit for outdoor or harsh-environment use.
The A23 supports ceiling, wall, and corner mounting; the BX1500V-301U is specified for wall mounting only. For retrofit corner installations or ceiling-drop brackets, the A23's broader mount compatibility is a practical advantage. Both share a box form factor suited to housing or pendant-arm deployment.
Which fits your VMS and analytics better?
Both cameras are ONVIF-compliant; the Geovision BX1500V-301U specifically lists ONVIF Profile S, confirming baseline live-stream and PTZ-control interoperability with any Profile S-certified VMS. The A23 lists ONVIF without specifying a profile level in the provided specifications. Neither camera's specifications include edge analytics capabilities (motion detection algorithms, people counting, line crossing, etc.) beyond what standard ONVIF implies.
The A23 includes a built-in microphone and supports MicroSDHC and MicroSDXC edge storage, giving it local buffering capability for network-drop resilience. The BX1500V-301U's provided specifications list neither onboard audio nor local storage, though absence from the spec sheet does not conclusively confirm those features are absent from the hardware — installers should verify with the full Geovision datasheet. The A23 also supports H.265 alongside H.264, reducing storage and bandwidth consumption by up to ~50% compared to H.264-only pipelines; the BX1500V-301U is H.264 only per the provided specifications.
Which should you choose: the A23 or the BX1500V-301U?
Our take: The A23 is the stronger choice when image detail, codec efficiency, and integration flexibility are priorities. Its 3 MP sensor delivers approximately 2.3× the pixel count of the BX1500V-301U's 1.3 MP sensor, directly supporting wider coverage or tighter forensic crop. H.265 support cuts bandwidth and storage requirements versus the Geovision's H.264-only compression. The A23 also adds a built-in microphone and MicroSDHC/MicroSDXC edge storage — neither of which appears in the BX1500V-301U's provided specs — and supports ceiling, wall, and corner mounting versus wall-only on the Geovision. The BX1500V-301U's stated advantage is Super Low Lux sensitivity; if minimum-illumination performance in near-darkness is the primary criterion and 1.3 MP resolution is acceptable, it warrants datasheet-level comparison once lux figures are available. For most commercial installs where detail, codec savings, and VMS storage integration matter, the A23 is the better-specified option at the same 13 W PoE power budget.

Is the A23 or BX1500V-301U better for low light?
Based on the provided specifications, the Geovision BX1500V-301U lists a Super Low Lux sensitivity rating, which suggests strong low-light capability. The A23 does not include a comparable low-light descriptor or a quantified minimum illumination value in the supplied specs. Neither camera provides a numeric lux figure in the data provided, so a definitive low-light ranking requires consulting each manufacturer's full datasheet.
Will both cameras work with my existing ONVIF VMS?
Yes — both cameras declare ONVIF compliance. The Geovision BX1500V-301U specifically certifies ONVIF Profile S, confirming live video streaming interoperability with any Profile S VMS. The ACTi A23 also lists ONVIF support, though the specific profile level is not stated in the provided specifications. Verify profile level with ACTi's datasheet if your VMS requires Profile S or T compliance.
Can I record locally on either camera without an NVR?
The ACTi A23 supports MicroSDHC and MicroSDXC edge storage, enabling local recording without an NVR on the network. The Geovision BX1500V-301U does not list any onboard storage option in the provided specifications. If network-independent local buffering is required, the A23 has a clear advantage based on the available data.
