Product SKU: DS-2780ZJ-X-316L
Product Overview
The Hikvision DS-2780ZJ-X/316L is a 316L stainless-steel explosion-proof terminal box designed for compatible CCTV and surveillance equipment used in hazardous-area installations. It provides a protected enclosure for power, network, alarm, audio, control and video connections while supporting multiple power-input options, including 110 to 240 VAC, 24 VAC, 8 to 36 VDC and PoE. The enclosure measures 272 × 272 × 96.8 mm, weighs approximately 6.4 kg and incorporates four M25 × 1.5 cable outlets. With IP68 ingress protection plus ATEX and IECEx explosion-proof certification, the DS-2780ZJ-X/316L is intended for specialised Zone 1, Zone 2, Zone 21 and Zone 22 applications where certified hazardous-area infrastructure is required.
Key Capabilities
316L Stainless-Steel Construction
The /316L version is manufactured from stainless steel 316L, providing the specified material grade for compatible surveillance projects requiring a corrosion-resistant hazardous-area enclosure.
ATEX & IECEx Certification
The enclosure is certified for explosion-proof performance and specified for Zone 1, Zone 2, Zone 21 and Zone 22 hazardous areas involving gas or combustible dust risks.
IP68 Ingress Protection
An IP68 rating provides a high level of dust and water ingress protection when the terminal box, cable entries and complete installation are assembled correctly.
Flexible Power Support
The DS-2780ZJ-X/316L supports compatible devices powered by 110 to 240 VAC, 24 VAC, 8 to 36 VDC or PoE 802.3af/at without relying on a preinstalled internal power adapter.
Comprehensive Signal Interfaces
The enclosure supports CVBS, RS-485, audio, alarm and RJ45 Ethernet connections, allowing multiple compatible surveillance connections to terminate within the protected housing.
Four Cable Outlets
Four M25 × 1.5 cable outlets provide dedicated cable-entry points, with sealing rings and M25-to-G3/4 thread adapters supplied for supported installation arrangements.
Best For
- Hazardous-Area Surveillance: Suitable for compatible CCTV installations in Zone 1, Zone 2, Zone 21 and Zone 22 environments.
- Industrial Facilities: Provides protected termination for compatible power, network, alarm, audio and control wiring.
- Multi-Power Camera Systems: Useful where supported equipment operates from AC, DC or PoE rather than a fixed 12 VDC output.
- 316L Stainless-Steel Projects: Appropriate where the project specifically requires the /316L version rather than the standard stainless-steel 304 enclosure.
Why Choose the DS-2780ZJ-X/316L
The DS-2780ZJ-X/316L is designed for specialised surveillance systems that require certified hazardous-area infrastructure rather than a conventional camera junction box. Its 316L stainless-steel enclosure, ATEX and IECEx certification, IP68 rating and broad power-input support make it suitable for compatible industrial CCTV equipment operating in demanding gas or dust hazardous zones. The absence of a preinstalled power adapter also gives system designers greater flexibility when the connected device already uses AC, DC or PoE power. Available through Security Wholesalers, the DS-2780ZJ-X/316L should always be specified as part of a complete certified installation with suitable cable glands, wiring methods and supporting structure.
Buyer Decision Tips
Buyer Tip: The DS-2780ZJ-X/316L does not include a preinstalled power adapter. If the intended device specifically requires a built-in 12 VDC 2 A supply from the terminal enclosure, compare it with the compatible DS-2781ZJ-X/316L configuration.
Buyer Tip: The installation surface must withstand eight times the weight of the terminal box. At approximately 6.4 kg before connected equipment and cabling are considered, structural support and compliant cable-entry hardware should be planned before installation.

Choosing the Right Model
- Choose this model if: The project requires an explosion-proof terminal box in stainless steel 316L without a preinstalled power adapter.
- Choose the standard DS-2780ZJ-X if: Stainless steel 304 is acceptable and the /316L material grade is not required.
- Consider the DS-2781ZJ-X/316L if: The compatible device requires a preinstalled 110–240 VAC to 12 VDC 2 A power adapter within the terminal box.
FAQs
- What is the Hikvision DS-2780ZJ-X/316L used for?
The Hikvision DS-2780ZJ-X/316L is an explosion-proof terminal box for compatible CCTV and surveillance equipment in hazardous-area installations. It provides protected cable termination, power and signal interfaces inside a 316L stainless-steel enclosure. Hikvision specifies four M25 × 1.5 cable outlets, IP68 ingress protection and ATEX and IECEx explosion-proof certification.
- What material is the DS-2780ZJ-X/316L made from?
The DS-2780ZJ-X/316L is manufactured from stainless steel 316L. Hikvision also offers the standard DS-2780ZJ-X in stainless steel 304, while the /316L version is the appropriate model where 316L stainless steel is specifically required for the project or environmental specification.
- What hazardous areas is the DS-2780ZJ-X/316L designed for?
Hikvision specifies the DS-2780ZJ-X/316L for Zone 1, Zone 2, Zone 21 and Zone 22 hazardous areas. It carries ATEX and IECEx explosion-proof certification with gas and dust protection markings and an IP68 ingress-protection rating. The complete installation still needs to meet the project’s applicable hazardous-area design and installation requirements.
- Does the DS-2780ZJ-X/316L include a power adapter?
No. The DS-2780ZJ-X/316L does not include a preinstalled power adapter. It is designed to accommodate compatible equipment using 110 to 240 VAC, 24 VAC, 8 to 36 VDC or PoE 802.3af/at power. This makes it different from the related DS-2781ZJ-X/316L, which includes a preinstalled 12 VDC power adapter.
- What interfaces are supported by the DS-2780ZJ-X/316L?
The terminal box supports 110 to 240 VAC, 24 VAC and 8 to 36 VDC power connections, CVBS, RS-485, one audio input, one audio output, two alarm inputs, two alarm outputs and an RJ45 Ethernet interface with PoE 802.3af/at support. For Security Wholesalers installations, the intended camera or device should be checked against these interfaces before deployment.
- What should be checked before installing the DS-2780ZJ-X/316L?
The installation surface must be strong enough to withstand eight times the weight of the terminal box. The enclosure itself weighs approximately 6.4 kg, so structural support should be planned carefully. Hikvision also specifies four M25 × 1.5 cable outlets and provides sealing rings and M25-to-G3/4 thread adapters for supported cable-entry arrangements.
