Dahua DHI-VTO4202F-P-S3 - 2MP 2-Wire IP Modular Video Intercom Door Station

Dahua VTO4202F-P-S3 - 2MP 2-Wire IP Modular Video Intercom Door Station

The Dahua DHI-VTO4202F-P-S3 is the camera module of Dahua's Pro Series modular apartment door station. It works on Dahua's digital 2-wire system, powered from a Dahua 2-wire switch up to 50m away, or over IP with PoE (802.3af/at) through its RJ-45 port.

The 2MP 1/2.9-inch camera has a 168.6 degree horizontal view, 120dB WDR and auto IR light compensation. Two-way audio uses echo suppression and digital noise reduction, and Dahua lists remote unlock and a card capacity of 3,000 when a card reader module is fitted.

The module has lock control, exit button, door status, alarm output and RS-485 connections, a 12V 600mA power output and a tamper alarm. Its silver aluminium casing is rated IP65 and IK07, works from -30 to +60 degrees C, and can be flush or surface mounted, with call button, keypad, card reader or info modules added alongside.

Also listed as VTO4202F-P-S3.

• Other modules: DHI-VTO4202F-MK keypad, DHI-VTO4202F-MR card reader (IC), DHI-VTO4202F-ML indicator, DHI-VTO4202F-MI info, DHI-VTO4202F-MN blank
• Mounting boxes: VTM79 (1 module), VTM127 (2 modules), VTM128 (3 modules)
• Front panels: VTM77 (1 module), VTM125 (2 modules), VTM126 (3 modules)
• Rain covers: VTM75 (1 module), VTM52R2 (2 modules), VTM53R3 (3 modules)
• 2-wire power: DHI-VTNS2003B-2-A 2-wire switch

Other suggested pairings:

• Dahua DHI-VTH5422HB 7-Inch Indoor Monitor: a 7-inch 2-wire and PoE IP indoor monitor for each flat
• Dahua DHI-VTH5422HW 7-Inch Indoor Monitor: a 7-inch indoor monitor from Dahua's 2-wire IP range

Pairings are suggested on general compatibility (same brand, matching connection type and specification), not as tested combinations.

What you will need

• At least one call-button module (or a keypad module) so visitors can call a flat
• A mounting box and front panel sized for the total number of modules, plus a rain cover for exposed positions
• Either a Dahua 2-wire switch (for 2-wire cabling) or a PoE network switch (802.3at if the 12 V output powers a lock)
• Dahua indoor monitors and/or the mobile app for residents, and an electric lock if you want door release
• Silicone sealant for the shell, as described in Dahua's quick start guide, to achieve the IP65 rating

Common questions

Is this a video intercom?

Yes. Dahua lists a video intercom function: the module has a camera, a built-in speaker and an audio input for two-way audio, and works with Dahua indoor monitors and the mobile app.

What is the difference between the VTO4202F-P-S3 and the VTO4202F-P?

The S3 version works on Dahua's digital 2-wire system (up to 50 m from a Dahua 2-wire switch) as well as over IP with standard PoE. Open the DHI-VTO4202F-P listing to compare its specification.

Can I use it over existing intercom wiring?

In 2-wire mode it runs from a Dahua 2-wire switch (maximum power supply distance 50 m). Please check your existing cable with us before reusing it.

Can it be used in a flat intercom system?

Yes. It is the camera module of Dahua's modular apartment door station, which Dahua shows with indoor monitors and a 2-wire switch, so it suits a flat intercom system or a video door entry system for a block of flats.

Can residents answer on their phone?

Yes. Dahua's mobile app lets users talk to visitors and unlock the door remotely.

Does it record visitors?

It supports leave-video messages when a Micro SD card (up to 256 GB) is fitted in the door station or indoor monitor.

Is it suitable for outdoor use?

Yes. Dahua lists the operating environment as outdoor: it is rated IP65 and IK07 and operates from -30°C to +60°C; fit a rain cover on exposed entrances.

Can it control an electric lock?

It has a lock control output, an exit button input and a door status input, plus a 12V 600mA power output. Check the lock's voltage and current against that output before wiring it.

Can it be powered by PoE?

Yes. As well as Dahua's 2-wire switch, it accepts PoE (802.3af/at) through its RJ-45 port. Dahua lists 4W standby and 5W working consumption.

Can visitors be seen at night?

It has auto IR light compensation and switches between colour and black and white automatically (ICR).
