Pelco IWP234-1ERS vs Pelco IWP236-1ERS: Specification Comparison
Both the Pelco IWP234-1ERS and IWP236-1ERS belong to the Sarix Pro 3 Wedge series — 2MP indoor fixed-lens cameras sharing an identical sensor platform, PoE Class 3 power, and wedge/corner form factor. The two models are direct cross-shop candidates that share nearly every listed specification. The sole differentiator surfaced in the provided specs is focal length: the IWP234-1ERS carries a 4mm lens while the IWP236-1ERS carries a 6mm lens, making field-of-view coverage angle the primary selection criterion for an installer.

How do the imaging specs compare?
Both cameras share a 1/2.8" CMOS sensor delivering 1920×1080 (2MP) at 30 fps. Aperture is F1.4 on both models. Both include Wide Dynamic Range (WDR) and day/night capability, with IR illumination noted at 850nm in the specs. Compression is identical: H.265, H.264, and MJPEG are listed for both. No minimum illumination figure is provided in the supplied specs for either model.
The one imaging-tier difference is focal length. The IWP234-1ERS is specced at 4mm, producing a wider field of view suited to shorter-range coverage of a hallway intersection or compact room corner. The IWP236-1ERS is specced at 6mm, producing a narrower field of view with greater reach down a longer corridor. No pixel density or angular field-of-view figures are provided in the supplied specs for either unit.
What about installation and environment?
Installation characteristics are identical across both models per the supplied specs. Both are rated IP52 for indoor ingress protection and IK09 for vandal resistance. Operating temperature is listed as -10°C to +60°C for both. Housing color is white on both. The wedge/corner mount type is shared, and both are classified for indoor environments only.
Power delivery is PoE Class 3 (802.3af) on both models. No dimensional or weight data is included in the provided specs for either camera, so rack-space or junction-box compatibility cannot be differentiated from these specs alone.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile S and Profile T compliant and carry a general ONVIF compatibility flag, making them interoperable with any ONVIF-conformant VMS. HTTPS encryption is listed as present on both. Audio input is noted for both models. On-board microSD storage is supported by both, enabling edge recording or buffering without additional NVR dependency.
No edge analytics, AI inference, or platform-specific VMS certifications beyond ONVIF are listed in the supplied specs for either model. Both reference the Pelco Discovery VX Toolbox for camera discovery. No differences in integration capability can be drawn from the provided data.
Which should you choose: the IWP234-1ERS or the IWP236-1ERS?
Our take: The IWP236-1ERS is the stronger choice when the deployment corridor is long and the installer needs reach at the cost of coverage width, while the IWP234-1ERS is the stronger choice when wide-angle coverage of a compact corner or intersection is the priority. The sole spec delta in the provided data is focal length: 4mm on the IWP234-1ERS versus 6mm on the IWP236-1ERS — a narrower angle and greater effective reach on the 236 versus a broader sweep on the 234. Every other listed specification — 2MP 1/2.8" CMOS sensor, F1.4 aperture, IK09, IP52, -10°C to +60°C operating range, PoE Class 3, ONVIF S/T, microSD, audio input, H.265/H.264/MJPEG, 5-year warranty — is identical. Platform fit is a non-factor between these two. Select by deployment geometry: 4mm for wide corner coverage, 6mm for longer-corridor reach.

Frequently Asked Questions
Which should you choose: the IWP234-1ERS or the IWP236-1ERS?
The IWP236-1ERS is the stronger choice when the deployment corridor is long and the installer needs reach at the cost of coverage width, while the IWP234-1ERS is the stronger choice when wide-angle coverage of a compact corner or intersection is the priority. The sole spec delta in the provided data is focal length: 4mm on the IWP234-1ERS versus 6mm on the IWP236-1ERS — a narrower angle and greater effective reach on the 236 versus a broader sweep on the 234. Every other listed specification — 2MP 1/2.8" CMOS sensor, F1.4 aperture, IK09, IP52, -10°C to +60°C operating range, PoE Class 3, ONVIF S/T, microSD, audio input, H.265/H.264/MJPEG, 5-year warranty — is identical. Platform fit is a non-factor between these two. Select by deployment geometry: 4mm for wide corner coverage, 6mm for longer-corridor reach.
Is the IWP234-1ERS or IWP236-1ERS better for a long hallway?
Based on the provided specs, the IWP236-1ERS with its 6mm fixed lens is better suited to a long hallway, where its narrower field of view provides greater reach down the corridor. The IWP234-1ERS carries a 4mm lens, which delivers a wider angle more appropriate for shorter-range corner or intersection coverage.
Do the IWP234-1ERS and IWP236-1ERS work with the same VMS?
Yes, per the provided specs both models are ONVIF Profile S and Profile T compliant and both reference compatibility with the Pelco Discovery VX Toolbox. No model-specific VMS certifications or restrictions appear in the supplied specs, so VMS platform compatibility is not a differentiating factor between the two.
Can either camera record locally without an NVR?
Yes. Both the IWP234-1ERS and IWP236-1ERS include microSD storage support per the provided specs, enabling local edge recording on both models. No microSD capacity limit or specific card class requirement is stated in the supplied specs for either unit.
