DG 204 MRG Handle Digital Door Lock with Built-In Camera and Intercom — Maximum Security Meets Visual Verification in Indore

Some entrances demand more than just a strong lock — they demand complete visibility too. The DG 204 MRG Handle Digital Door Lock delivers both at once. It combines a built-in HD video camera, a real-time 2-way intercom, and the strongest physical locking mechanism in the DG 204 range — the 3-bolt MRG system. Because of this combination, you not only secure your door against forced entry at three separate points, you also get to see and speak to every visitor before you ever decide to let them in. As a result, the DG 204 MRG is the most secure and visually intelligent lock available for homes and businesses in Indore today.

📹 Built-In HD Video Camera — See Every Visitor Clearly

First and foremost, what defines the DG 204 MRG is its integrated HD video camera. Because the camera is built directly into the lock handle, you do not need a separate video door phone unit to see who is at your door. Instead, the moment someone approaches, you can:

• View a live HD video feed of your entrance directly through the mobile app
• See visitors clearly before deciding whether to open the door, speak to them, or ignore the call
• Capture visual evidence of deliveries, visitors, and any unexpected activity at your entrance
• Check your doorstep remotely at any time, even when nobody has rung or knocked

Therefore, you gain complete visual awareness of your entrance — not just a record of who entered, but a clear picture of who was actually there.

🎙️ Real-Time 2-Way Intercom — Speak to Visitors From Anywhere

Furthermore, the DG 204 MRG includes a real-time 2-way intercom, so you can talk to whoever is at your door without opening it — and without even being home. Because the intercom works through the mobile app, you can:

• Speak directly to a visitor through your smartphone, from anywhere with an internet connection
• Ask a delivery driver to leave a package safely without unlocking the door at all
• Verify a visitor’s identity by speaking with them before granting access
• Reassure family members by talking them through entry instructions remotely if needed

As a result, the DG 204 MRG gives you the same peace of mind as a traditional video door phone, but built directly into the strongest lock in the DG range — with no separate intercom unit required.

🔒 3-Bolt MRG Locking System — Maximum Physical Security at Three Points

In addition to its camera and intercom, the DG 204 MRG is built on a 3-bolt MRG locking mechanism — delivering the strongest physical security available in the DG 204 range. While a standard single-bolt lock secures the door at just one point, the MRG system engages three separate bolts simultaneously the moment the door locks. Because of this triple-point engagement, you get:

• Significantly stronger resistance against forced entry, kick-in attacks, and prying attempts
• Better load distribution across the full height of the door frame under pressure
• Reduced door flex — three locking points hold the door firmly in position at all times
• A tighter, more secure fit between the door leaf and the frame at every contact point
• Greater overall protection for main entrances, front doors, and high-priority access points

Therefore, the DG 204 MRG does not just let you see who is at your door — it backs that visibility with one of the strongest physical locking systems anywhere in the DG range.

🆚 DG 204 MGM vs DG 204 MRG — Understanding the Difference

Both the MGM and MRG variants of the DG 204 share an identical camera, intercom, and smart feature set. However, they differ in their internal bolt mechanism and hardware design:

📱 Wi-Fi App Control — Manage Your Door and Camera from Anywhere

Moreover, the DG 204 MRG connects over Wi-Fi, giving you complete remote control of both the lock and the camera through a single mobile app. Because of this, you can:

• Unlock your door remotely after viewing and speaking to a visitor through the app
• Lock your door remotely — secure your home or office even when you are far away
• View live camera footage and use the intercom from anywhere in the world
• Grant and revoke access instantly — add or remove users from your phone without touching the lock
• Check your door status in real time — see whether your door is locked or unlocked at any moment

Furthermore, because the app combines video, intercom, and access control in one interface, managing your entrance becomes simple and intuitive — everything you need sits in one place.

🔑 OTP Access — Safe Temporary Entry, Backed by Visual Verification

In addition, the DG 204 MRG supports OTP (One Time Password) access, and because of the built-in camera, you can now see exactly who is using that code before they enter. With OTP access, you can:

• Generate a single-use entry code for a guest, delivery driver, or service technician
• Watch them arrive on camera and confirm their identity before the code is even used
• Set an expiry time so the code becomes invalid automatically after use or after a set period
• Send the OTP remotely via the app — no need to be physically present at the door at all

As a result, you get not just convenient temporary access, but visual confirmation of exactly who used it — adding an extra layer of confidence to every single entry.

📋 Activity Logs with Visual Context

Furthermore, the DG 204 MRG keeps a detailed activity log of every door event — and because of the built-in camera, many of these events can be paired with visual context. Because of this, you can:

• Review who entered your home or office and exactly when they did so
• Cross-reference access logs with camera footage for complete clarity on any event
• Identify unusual access patterns — such as unexpected entries at odd hours
• Maintain a complete, visually-backed security record for accountability and peace of mind

Therefore, the DG 204 MRG gives you not just a record of access, but a clearer picture of exactly what happened at your door.

🔓 Five Ways to Unlock — App, Finger, Card, PIN and Key

Moreover, the DG 204 MRG gives you five independent unlocking methods, so every household member or team member can use whichever method suits them best:

• 📱 Mobile App — unlock remotely after viewing the visitor on camera, from anywhere in the world
• 👆 Fingerprint — press your finger and the door unlocks instantly, with excellent personal security
• 💳 Card — tap your access card to unlock, ideal for offices and shared spaces
• 🔢 PIN Code — enter your personal code on the keypad, a dependable everyday backup
• 🗝️ Mechanical Key — a traditional key backup for when batteries need replacing

Because all five methods work independently, every user gets the access option that suits them, while you retain full visual oversight of every entry through the built-in camera.

👥 Up to 100 Unique Users — Ideal for Homes and Small Businesses

Furthermore, the DG 204 MRG stores access credentials for up to 100 unique users, making it suitable for homes, offices, rental properties, and small businesses alike. Because you can also view anyone approaching the door via camera, you get an extra layer of confirmation alongside standard user management — particularly useful for verifying staff, family members, or visitors at busy entrances.

📏 Fits Door Thickness from 35mm to 90mm

In addition, the DG 204 MRG fits a wide range of standard door thicknesses — from 35mm to 90mm — making it compatible with most residential and commercial doors. Moreover, AlifTech Secure’s trained installation team handles the complete fitting, camera alignment, Wi-Fi configuration, and app setup — so your video and intercom features work perfectly from day one.

📡 Optional VDP and Home Automation Compatibility

Furthermore, because the DG 204 MRG already includes a built-in camera and intercom, it can reduce or even replace the need for a separate VDP system in many setups. However, it still supports optional VDP integration and home automation compatibility for those who want to connect additional cameras, intercoms, or smart devices as part of a larger security ecosystem.
