Product SKU: DS-2781ZJ-X-316L
Product Overview
The Hikvision DS-2781ZJ-X/316L is a 316L stainless-steel explosion-proof terminal box designed for compatible 12 VDC equipment used in hazardous-area surveillance installations. It combines ATEX and IECEx certified explosion-proof performance with IP68 ingress protection, four M25 × 1.5 cable outlets and a preinstalled power adapter, providing a dedicated termination point for power, network, alarm, audio and control connections. Measuring 272 × 272 × 96.8 mm and weighing approximately 6.7 kg, the enclosure is suitable for Zone 1, Zone 2, Zone 21 and Zone 22 hazardous areas. Its operating range extends from -40°C to +60°C, making it a specialised infrastructure component for demanding CCTV systems rather than a conventional camera mounting bracket.
Key Capabilities
316L Stainless-Steel Construction
The /316L variant is manufactured from stainless steel 316L, providing the specified material option for projects requiring this grade of corrosion-resistant enclosure.
ATEX & IECEx Explosion-Proof Certification
The terminal box is certified for explosion-proof performance and is specified for Zone 1, Zone 2, Zone 21 and Zone 22 hazardous-area installations.
IP68 Ingress Protection
An IP68 ingress-protection rating helps protect the terminal enclosure in demanding installations when approved cable glands, sealing methods and installation procedures are correctly followed.
Preinstalled Power Adapter
The built-in power adapter accepts 110 to 240 VAC input and provides 12 VDC 2 A output for compatible 12 VDC devices, reducing the need for a separate external conversion stage.
Comprehensive Signal Interfaces
The enclosure provides Ethernet, CVBS, RS-485, audio and alarm interfaces, allowing multiple supported connections to be terminated within the protected explosion-proof housing.
Four Cable Outlets
Four M25 × 1.5 cable outlets provide dedicated routing points for power, network and other supported connections using certified glands sealed with setting compound.
Best For
- Hazardous-Area CCTV Systems: Suitable for compatible surveillance installations located in Zone 1, Zone 2, Zone 21 or Zone 22 environments.
- Industrial Facilities: Provides protected termination for compatible camera equipment where explosion-proof electrical infrastructure is required.
- 12 VDC Equipment: Includes a preinstalled power adapter supplying 12 VDC 2 A output to supported devices.
- Multi-Interface Installations: Useful where Ethernet, RS-485, CVBS, audio and alarm connections need to be brought together inside one protected enclosure.
Why Choose the DS-2781ZJ-X/316L
The DS-2781ZJ-X/316L is designed for surveillance installations that require substantially more than a standard CCTV junction box. Its 316L stainless-steel body, ATEX and IECEx explosion-proof certification, IP68 protection and hazardous-area classification make it suitable for specialised industrial applications where certified equipment is essential. The preinstalled 110–240 VAC to 12 VDC 2 A power adapter and comprehensive signal interfaces also consolidate several system connections inside one protected enclosure. Available through Security Wholesalers, the DS-2781ZJ-X/316L should be specified as part of a fully compliant hazardous-area system, with the selected device, cable glands, wiring and installation method matched to the project’s certification requirements.
Buyer Decision Tips
Buyer Tip: This product is an explosion-proof terminal box, not a camera wall-mount bracket. It is intended to provide protected power, network, control, audio and alarm termination for compatible hazardous-area surveillance equipment.
Buyer Tip: Hikvision specifies certified cable glands sealed with setting compound for cable routing. The installation surface must also withstand eight times the terminal box weight, so both certified accessories and structural support need to be planned before installation.

Ideal Use Cases
Hazardous Industrial Areas
Provides certified explosion-proof termination for compatible surveillance equipment operating in designated gas or dust hazardous zones.
Process Facilities
Useful where compatible 12 VDC surveillance devices require protected power, network, alarm and control connections within one enclosure.
Dust Hazard Locations
Suitable for certified Zone 21 and Zone 22 applications when installed as part of a compliant hazardous-area surveillance system.
Corrosion-Resistant Systems
The 316L stainless-steel variant is suited to projects that specifically call for this material grade in addition to explosion-proof system requirements.
Choosing the Right Model
- Choose this model if: The project specifically requires the DS-2781ZJ-X terminal box in 316L stainless steel for compatible hazardous-area equipment.
- Choose the standard DS-2781ZJ-X if: Stainless steel 304 is the specified material and the /316L variant is not required.
- Choose a camera bracket instead if: The requirement is simply to mount a camera to a wall, ceiling or pole, as the DS-2781ZJ-X/316L is an electrical terminal enclosure rather than a camera mounting arm.
FAQs
- What is the Hikvision DS-2781ZJ-X/316L used for?
The Hikvision DS-2781ZJ-X/316L is an explosion-proof terminal box for compatible 12 VDC devices and hazardous-area surveillance installations. It provides four M25 × 1.5 cable outlets, IP68 ingress protection, a preinstalled power adapter and multiple electrical and communication interfaces. It is not a wall-mount camera bracket.
- Is the DS-2781ZJ-X/316L a wall mount bracket?
No. The supplied Hikvision datasheet identifies the DS-2781ZJ-X/316L as an explosion-proof terminal box. Its role is to provide protected power, signal and cable termination for compatible equipment in hazardous-area installations rather than to act as a projecting camera wall bracket.
- What material is the DS-2781ZJ-X/316L made from?
The /316L version is manufactured from stainless steel 316L. Hikvision also lists a standard DS-2781ZJ-X version made from stainless steel 304. The 316L variant is the appropriate model when that higher-grade stainless-steel material is specifically required by the project.
- What hazardous areas is the DS-2781ZJ-X/316L designed for?
The datasheet lists the terminal box for Zone 1, Zone 2, Zone 21 and Zone 22 hazardous areas. It also lists ATEX and IECEx certified explosion-proof performance with markings II 2 G Ex db IIC T6 Gb and II 2 D Ex tb IIIC T80°C Db IP68. Project certification requirements should still be checked against the complete installation.
- What power and interfaces are provided by the DS-2781ZJ-X/316L?
The terminal box has a preinstalled power adapter with 110 to 240 VAC input and 12 VDC 2 A output. The datasheet also lists CVBS, RS-485, one audio input, one audio output, two alarm inputs, two alarm outputs and an RJ45 Ethernet interface. Security Wholesalers installations should match these interfaces to the intended compatible device before deployment.
- What should be checked before installing the DS-2781ZJ-X/316L?
The installation surface must be strong enough to withstand eight times the weight of the device. Hikvision also instructs installers to use certified cable glands sealed with setting compound for cable routing and to follow the installation guide. The terminal box itself weighs approximately 6.7 kg, so structural support should be planned carefully.
