Pelco SRXE4-6V9-EMD-1 vs Pelco SRXE4-8V29-IMD-IR1: Specification Comparison
Both the Pelco SRXE4-6V9-EMD-1 and the SRXE4-8V29-IMD-IR1 belong to the Sarix Enhanced 4 Series and share the same 4MP resolution class, motorized varifocal lens range, and dome form factor—making them direct cross-shop candidates for integrators selecting a fixed IP dome camera. The key differentiators are deployment environment (outdoor hardened versus indoor IR-equipped), cold-temperature tolerance, IR illumination capability, and ingress protection depth. This comparison addresses those deltas using only the provided specifications.

How do the imaging specs compare?
Both cameras share a 1/1.8-inch progressive scan CMOS sensor, 2560×1440 (4MP) maximum resolution, a 4.4–9.3 mm motorized varifocal lens covering 32–109° HFOV, F1.4 aperture, 130 dB SureVision WDR, and H.265/H.264/Motion JPEG compression. The SRXE4-6V9-EMD-1 specifies a minimum illumination of 0.003 lux color and 0.001 lux monochrome (B/W), indicating a mechanical or electronic day/night cut filter for low-light sensitivity. The SRXE4-8V29-IMD-IR1 specifies 0.003 lux color and 0 lux IR, reflecting its integrated IR1 illuminator (850 nm) that enables true-dark imaging when IR is active.
Frame rate is listed as 60 fps for the SRXE4-6V9-EMD-1 across both its primary spec field and its card bullets. The SRXE4-8V29-IMD-IR1 lists 60 fps in its primary spec field but 30 fps in its Frame Rate attribute field—these values are internally inconsistent in the provided data, so installers should verify the confirmed sustained frame rate against Pelco's datasheet before deployment in high-motion scenes. IR range for the IMD-IR1 is cited as approximately 70 m (850 nm) in the enriched fields; no IR illuminator is specified for the EMD-1.
What about installation and environment?
The SRXE4-6V9-EMD-1 carries IP66, IP67, IP68 (2 m for 2 hours), IPX9K, and NEMA 4X ratings, plus IK11 mechanical impact resistance—making it suitable for exposed outdoor installations subject to high-pressure washdowns, temporary submersion, and extreme weather. Its operating temperature range is −50°C to +65°C (with PoE+ or external power supplied), covering arctic and high-heat environments. The SRXE4-8V29-IMD-IR1 is rated IP66 only and carries an indoor environment rating with an operating temperature of −10°C to +65°C, limiting it to protected or conditioned indoor spaces and moderate-climate covered outdoor areas.
Both cameras support PoE (Class 3) and list PoE+ (802.3at) in their power attributes; the IMD-IR1 additionally notes 12/24 Vdc as an alternative power input in its enriched fields, which the EMD-1 does not explicitly state in the provided data. Both share the same dome form factor and the same listed mounting options (wall, ceiling, pole, pendant, corner, recessed). Dimensions are identical in the provided data for both units: 182×132 mm (DxH) in the base configuration.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profile S, Profile T, Profile G, and Profile M, ensuring broad VMS compatibility. Both carry the same Smart Analytics feature set: Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. Both include microphone support, microSD on-board storage, HTTPS encryption, and 802.1X port-based network access control. Cybersecurity posture is identical: FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X are specified for both models.
Both units hold NDAA Section 889 and TAA compliance approvals, relevant for federal and government-funded installations. Certifications listed for both include UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, and BIS. Neither model shows a meaningful integration differentiation beyond their environmental and illumination profiles—VMS choice, analytics workload, and on-board storage requirements will be equally supported by either unit.
Which should you choose: the SRXE4-6V9-EMD-1 or the SRXE4-8V29-IMD-IR1?
Our take: The SRXE4-6V9-EMD-1 is the stronger choice when the deployment site demands outdoor-hardened durability, extreme-temperature operation, or high-pressure washdown tolerance. Its IP68/IPX9K/NEMA 4X ingress rating and −50°C floor give it a decisive advantage over the IMD-IR1's IP66-only, −10°C floor profile. Conversely, the SRXE4-8V29-IMD-IR1 is the correct selection for indoor corridors or low-ambient-light interior spaces where an integrated 850 nm IR illuminator with approximately 70 m range eliminates the need for supplemental lighting infrastructure—a capability absent from the EMD-1's specifications. Both units share identical sensor resolution (4MP/2560×1440), lens range (4.4–9.3 mm motorized varifocal), WDR (130 dB), analytics suite, ONVIF profiles, and cybersecurity posture. Select the EMD-1 for harsh outdoor or washdown environments; select the IMD-IR1 for dark-interior or corridor applications where onboard IR is the primary night-vision mechanism.

Frequently Asked Questions
Which should you choose: the SRXE4-6V9-EMD-1 or the SRXE4-8V29-IMD-IR1?
The SRXE4-6V9-EMD-1 is the stronger choice when the deployment site demands outdoor-hardened durability, extreme-temperature operation, or high-pressure washdown tolerance. Its IP68/IPX9K/NEMA 4X ingress rating and −50°C floor give it a decisive advantage over the IMD-IR1's IP66-only, −10°C floor profile. Conversely, the SRXE4-8V29-IMD-IR1 is the correct selection for indoor corridors or low-ambient-light interior spaces where an integrated 850 nm IR illuminator with approximately 70 m range eliminates the need for supplemental lighting infrastructure—a capability absent from the EMD-1's specifications. Both units share identical sensor resolution (4MP/2560×1440), lens range (4.4–9.3 mm motorized varifocal), WDR (130 dB), analytics suite, ONVIF profiles, and cybersecurity posture. Select the EMD-1 for harsh outdoor or washdown environments; select the IMD-IR1 for dark-interior or corridor applications where onboard IR is the primary night-vision mechanism.
Is the SRXE4-6V9-EMD-1 or SRXE4-8V29-IMD-IR1 better for low-light performance?
They serve different low-light scenarios. The SRXE4-6V9-EMD-1 specifies a 0.001 lux monochrome minimum illumination, which means it can capture usable image in near-dark conditions with ambient light present. The SRXE4-8V29-IMD-IR1 specifies 0 lux with its integrated IR1 illuminator active at approximately 70 m range (850 nm), meaning it can image in complete darkness using its own onboard illumination. If the site has zero ambient light, the IMD-IR1's integrated IR is the functional choice; if low ambient light is present and IR infrastructure is separate, the EMD-1's 0.001 lux sensitivity is competitive.
Can the SRXE4-8V29-IMD-IR1 be used outdoors?
Based on the provided specifications, the SRXE4-8V29-IMD-IR1 carries an indoor environment rating and is rated IP66 only, with a lower cold-temperature floor of −10°C. It is not rated IP67, IP68, IPX9K, or NEMA 4X, and it lacks the −50°C cold-weather tolerance of the EMD-1. It may tolerate a covered or sheltered outdoor location in mild climates, but it is not specified for exposed outdoor or washdown environments. The SRXE4-6V9-EMD-1 is the specified outdoor-rated unit between the two.
Do both cameras support the same VMS integrations and edge analytics?
Yes. Both cameras specify identical ONVIF compliance (Profile S, T, G, and M) and the same Smart Analytics feature set including Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. Both also share the same cybersecurity certifications (FIPS 140-3 Level 3, TPM, Secure Boot, 802.1X), microSD storage support, and NDAA/TAA compliance. The choice between them should be driven by environmental and illumination requirements, not VMS or analytics compatibility.
