Pelco HEG37K2A000 365mm Outdoor Housing
The Pelco HEG37K2A000 is a purpose-built outdoor housing for extended camera and lens assemblies that exceed standard 320mm form factor limitations. If your deployment requires longer optical configurations—oversize lens housings, extended barrel designs, or specialty sensor packages—this 365mm frame accepts them where standard housings cannot. The extended length directly translates to fewer installation compromises: you choose your optics first, then mount them, rather than constraining your lens selection to fit a shorter housing.
Key Features
- 365mm Extended Form Factor: Accommodates longer camera and lens combinations that standard housings reject. Reduces the need for external lens tubes or field modifications that compromise weatherproofing.
- Integrated Sun Shield and Heater: Built-in thermal management prevents lens fogging and internal condensation during temperature swings. In climates with morning dew or rapid heating cycles, this eliminates a common failure mode on unheated housings.
- Dual Voltage Input (12 VDC or 24 VAC): Accepts both direct DC (for battery-backed or UPS-fed sites) and transformer-fed AC power. Flexibility matters when retrofitting into existing infrastructure that may lack standardized power distribution.
- IP66 Environmental Rating: Direct rain and dust ingress are blocked—suitable for rooftop, perimeter, and industrial mounting. IP66 stops casual spray and dust storms but is not rated for full submersion; if you need underwater or washdown-intense duty, specify IP67 or higher.
- ONVIF Compatibility: Engineered to integrate with ONVIF-compliant Pelco IP cameras and third-party surveillance devices. Simplifies multi-vendor deployments and reduces proprietary lock-in risk.
- NDAA Section 889 Compliance: Meets U.S. federal procurement requirements for government and critical infrastructure contracts. Eliminates compliance documentation overhead if your customer requires it.
- 5-Year Warranty: Extended coverage reduces lifecycle replacement costs and supports long-term capital planning for permanent outdoor installations.
Installation & Power Considerations
The HEG37K2A000 supports both 12 VDC and 24 VAC input, eliminating the need to source dual-voltage variants for mixed-infrastructure sites. For PoE-powered camera modules, confirm your camera's power draw against your switch's budget; PoE+ (802.3at) supplies up to 30W per port, sufficient for most compact modules with integrated heaters, but verify your specific optics and sensor combination before final procurement. The integrated heater requires active power during cold months—budget accordingly on sites relying on remote battery backup.
Deployment Contexts
This housing excels in perimeter security, traffic enforcement, and long-distance optical applications where specialized lens barrels (extended telecentrics, macro-focus units, or custom IR-corrected assemblies) require extra physical clearance. Industrial facilities with legacy PTZ or specialty surveillance lenses often fit this profile. Government and critical infrastructure installations benefit from the NDAA compliance and extended warranty for reduced audit and replacement friction.
For a detailed assessment of outdoor IP camera integration and housing selection strategy, consult your facility's camera selection guide. If power distribution is a constraint, review PoE planning to confirm your switch meets simultaneous camera and heater demand.
Frequently Asked Questions
Q: Is the Pelco HEG37K2A000 compatible with non-Pelco cameras?
A: Yes. The HEG37K2A000 is engineered for ONVIF-compatible devices, including third-party IP cameras from other manufacturers. Verify the camera's form factor and mounting interface before purchase.
Q: Can I use the HEG37K2A000 in fully submerged or washdown environments?
A: No. IP66 rating protects against rain and dust spray but does not cover full submersion or high-pressure washdown. For those applications, specify an IP67 or higher-rated housing.
Q: What is the warranty coverage on the HEG37K2A000?
A: The product includes a 5-year manufacturer warranty covering defects in materials and workmanship.
Q: Does the integrated heater require separate power control or thermostat?
A: The heater is integrated into the housing power circuit. Confirm with your system integrator whether your camera module or external controller supplies thermostat logic; some deployments require a separate environmental sensor and relay.
Q: What is the maximum extended length this housing can accommodate?
A: The 365mm form factor is designed for camera and lens assemblies that exceed 320mm but fall within standard industry lengths. Consult the full datasheet or your integrator if you have custom or exceptionally long barrel designs.

The Pelco HEG37K2A000 solves a real integration friction point: optical assemblies that simply do not fit into standard-length housings. I have seen too many field installations compromise on lens choice or resort to external adapters that degrade weatherproofing. The 365mm extended form factor eliminates that tradeoff, provided you are mounting fixed or motorized optics longer than 320mm.
Technical Highlights:
- 365mm Housing Length: Directly accommodates extended camera/lens combinations that standard housings cannot physically accept. Reduces field modifications and external adapter creep that introduce leak paths.
- Dual Voltage Input (12 VDC or 24 VAC): Flexibility across DC-backed UPS systems and transformer-fed infrastructure. Real value on mixed-power sites where you cannot mandate a single standard.
- Integrated Sun Shield and Heater: Prevents lens fogging and condensation-induced sensor artifacts. In cold-weather perimeter deployments, this is not optional—it is the difference between usable imagery and fog-obscured feeds during morning hours.
- IP66 Rating with NDAA Compliance: Meets federal procurement rules and withstands outdoor rain/dust duty. Not rated for full submersion, so confirm your washdown or near-water environment does not exceed IP66 limits.
Deployment Considerations:
- Verify your camera module and any integrated heater draw against your PoE+ budget (30W max on 802.3at). Heater-equipped cameras consume 5–10W during active heating cycles; stack that alongside your sensor power and you may exceed a single 802.3af port (13W max).
- The integrated heater operates continuously in cold weather. Battery-backed or remote-power sites must account for this current draw; thermostat logic (on/off via external controller) is not built-in, so you may need environmental sensing relays if your facility demands power-efficient operation.
- Standard industry lengths assume modular camera + lens pairing within ~365mm total depth. If your optics are bespoke or exceed this envelope, confirm physical fit before ordering.
Deploy the HEG37K2A000 when optical requirements drive your choice first and housing form factor must bend to match. Perimeter security with specialized long-range or macro lenses, government critical-infrastructure projects requiring NDAA compliance, and industrial sites with legacy surveillance optics are textbook fits. If your deployment uses standard compact modules in a compact form factor, a smaller housing will suffice and saves cost and weight.
