Hikvision DS-K7P04 No-Touch Infrared Exit Button

The DS-K7P04 is a no-touch infrared exit button designed as an accessory for Hikvision access control systems and compatible third-party door control infrastructure. This device eliminates the need for occupants to physically contact a surface during egress—a practical advantage in environments where minimizing contact surfaces reduces cross-contamination risk, particularly in healthcare, government, and high-traffic commercial facilities.

Key Features

• Infrared sensor operation: Detects hand or motion within the active zone without requiring physical contact. Reduces wear on mechanical buttons and eliminates the hygiene concern of shared touch surfaces—meaningful in facilities processing dozens of people per hour.
• Stainless steel panel construction: Withstands corrosive environments and frequent cleaning with disinfectant wipes or spray. Matters if your facility uses harsh cleaning protocols or operates in high-humidity areas like hospitals or commercial kitchens.
• Flexible output configuration: Supports NO (normally open), NC (normally closed), and COM (common) contact options, allowing you to wire the DS-K7P04 into existing door release logic, electronic strikes, or access control panels without custom adapters. Simplifies integration with legacy systems.
• Compact form factor (90 × 35 × 37.7 mm): Fits narrow doorframes and tight architectural spaces where a standard push button won't mount. Relevant if you're retrofitting older buildings with limited wall/frame depth.
• Low power draw: Operates on 30 VDC at a maximum 1 A, reducing strain on your power supply and control panel. Most access control systems already source 12V or 24V, so a separate 30 VDC supply may be required—factor this into your wiring plan.
• Proven cycle rating: Passes 1 million actuation cycles in aging tests, supporting long-term reliability in high-traffic areas. Equivalent to roughly 3–5 years of normal use in a busy corridor.
• Wide operating temperature range: Functions reliably from -20°C to 50°C (-4°F to 122°F), so it won't fail in unheated warehouse exits, outdoor loading dock access points, or spaces without climate control.
• High humidity tolerance: Rated to 0–95% relative humidity, meaning condensation, steam, or wet environments won't degrade the sensor or contacts. Suitable for kitchens, bathrooms, or washdown areas.

Integration & Compatibility

The DS-K7P04 integrates with Hikvision access control systems and any third-party door control or access control panel that accepts dry-contact relay inputs. Verify your control panel or door release module supports the relay voltage and current before purchase. Wiring is straightforward: connect the NO/NC/COM terminals to your door strike, electric latch, or panel input as required by your system design.

Typical Applications

Deploy the DS-K7P04 at emergency exits, restrooms, secure doorways, or any egress point where contactless operation improves hygiene or convenience. Common installations include corporate offices, hospitals and clinics, government buildings, manufacturing floors, and food service facilities where frequent hand contact on exit buttons increases cross-contamination risk or maintenance burden.

Frequently Asked Questions

Q: Does the DS-K7P04 work with non-Hikvision access control panels?

A: Yes. The device outputs a dry-contact relay signal (NO/NC/COM), so it integrates with any access control system, door release module, or electromechanical latch that accepts relay inputs. Verify voltage and current compatibility with your specific panel before wiring.

Q: What power supply do I need?

A: The DS-K7P04 requires a dedicated 30 VDC supply rated for at least 1 A. Most access control panels source 12V or 24V, so you will likely need a separate 30 VDC power module unless your system already provides this voltage. Check your panel's power distribution before installation.

Q: Can I use the DS-K7P04 outdoors?

A: Yes, within its operating temperature range (-20°C to 50°C). The stainless steel construction resists weather and salt spray. However, verify installation location does not expose the sensor lens directly to rain or ice buildup, which could block infrared detection.

Q: How far away does a hand need to be to trigger the sensor?

A: Exact detection distance is not specified in the datasheet. Test the unit in your deployment environment to confirm the sensor responds at the desired distance. Typical infrared proximity sensors trigger within 10–30 cm (4–12 inches), but confirm with the device in situ.

Q: What is the warranty?

A: Warranty terms are not provided in the available documentation. Contact the distributor or Hikvision directly for warranty details and coverage terms.

Q: Is the DS-K7P04 suitable for high-traffic areas?

A: Yes. The 1 million cycle aging test rating supports sustained use in busy corridors. Contactless operation also eliminates wear from repeated button pressing, extending the device's service life compared to mechanical push buttons.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The DS-K7P04 (often searched as DS K7P04) is a straightforward accessory—not a complex device. It's a relay-triggered infrared proximity switch that outputs a dry contact, so it pairs with your existing access control panel, door release module, or electronic strike without requiring API integration or network configuration. That simplicity is its strength in retrofit or new-build scenarios where wiring complexity matters.

Technical Highlights:

• 30 VDC, 1 A maximum draw: Most access control panels distribute 12V or 24V natively, so the DS-K7P04 will require its own 30 VDC power supply. Plan dedicated wiring and a separate supply module; don't assume your panel's power bus can absorb this load.
• 1 million cycle rating: This is a real number from the datasheet, not marketing fluff. In a facility with 500+ daily egress events per door, that's roughly 5–6 years of service. Real-world performance will vary with environmental stress and cleaning chemicals used near the device.
• Stainless steel + 0–95% humidity tolerance: If your site uses bleach, quaternary ammonia, or salt-spray environments (coastal facilities, food processing), the stainless panel holds up. Verify that cleaning staff won't spray the lens directly; accumulated mineral deposits or soap film will kill infrared sensing.

Deployment Considerations:

• Sensor detection range unspecified: The datasheet does not publish the infrared range or minimum trigger distance. Before full rollout, test a sample unit at your facility. Hand height, ambient light, and lens cleanliness all affect performance. If the range is marginal (e.g., requires a hand within 5 cm), occupants may perceive slow or inconsistent response.
• Power supply planning: A 30 VDC, 1 A supply is not standard in most office or retail access control closets. Confirm you have a free circuit or an available power module before ordering multiple units. Missing this requirement will delay installation.

The DS-K7P04 is best suited for retrofit projects in healthcare, government, or food service where hygiene concerns justify the cost of contactless exit buttons, and where the facility already operates or can easily add a 30 VDC power source. In standard office or retail deployments with simple electronic strikes powered by 12V or 24V, the added wiring and supply complexity may not justify the benefit over a standard push button.
