Canon VB-M640V Manual

Power can be supplied to the camera in the three ways described below. Please be sure to read 

the user manual for the dedicated power supply before use.

 Note

•  Power supply should conform to all local codes.
•  The power supply should also comply with IEC/UL60950-1(SELV/LPS) standards.



 PoE (Power over Ethernet)

The camera supports PoE functions. Power can be supplied to the camera by using a LAN cable 

connected to a PoE HUB that conforms to the IEEE802.3at Type1 standard.

 Important 

•  Check with your dealer for more information about PoE HUB and Midspan technology. 

Midspan (a LAN cable power supply device) is a device that, like a PoE HUB, supplies power to the 
camera via a LAN cable.

•  Some PoE HUBs allow the limitation of currents for each port, but applying limits may interfere with 

performance. If using this type of PoE HUB, do not limit the operating current.

•  Some PoE HUBs have limits for the total current consumption for the ports, which can interfere with 

performance when multiple ports are in use. For more information, check the instruction guide for your 
PoE HUB.

•  

 

 When the camera is connected to both a PoE HUB and an external power supply 

(12 V DC or 24 V AC), power from the power supply first connected is given priority. But when both 
power supplies are connected, according to the combination, problems such as failure of the network 
connection may occur. When a problem has occurred, either shut off the PoE HUB power supply setting 
or use the AC adapter that is sold separately as the external power supply.



 External Power Supply 

 

12 V DC or 24 V AC input can be used.

Connect the power connector included in the package, as shown below.

Screwdriver

Tightening torque: 0.25 N·m (max.)

Strip

Approx. 5 – 7 mm

(0.20 – 0.28 in.)

Power connector 

(included)

12 V DC can be connected in a non-polar configuration.

 Important 

•  The power supply should be within the following voltage range.
•  24 V AC:  Voltage fluctuation within ±10% of 24 V AC (50 Hz or  

60 Hz ±0.5 Hz or less) 
Current supply capacity of at least 1.0 A per camera

•  12 V DC:  Voltage fluctuation within ±10% of 12 V DC 

Current supply capacity of at least 1.5 A per camera

•  When using a 12 V DC battery power supply, be sure to connect 

resistors of at least 0.5 – 1.0 Ω/20 W in series to the power line.

•  For an external power supply, use a double-insulated device.

Use UL cable (UL-1015 or equivalent) for 12 V DC or 24 V AC wiring. 



 AC Adapter 

 

Please use the dedicated AC adapter (sold separately).

External device I/O terminals consist of two input and output systems each. Viewer can be used 

to check external device input status and control output to an external device please refer to the

 

“Operation Guide”.



 External Device Input Terminals (IN1, IN2)

External device input terminals consist of two sets (IN1, IN2) of two terminals, with the negative

terminals connected to the camera interior GND. Connecting cables to the positive and negative 

terminals and opening or closing the circuit notifies the Viewer.

 Important

•  When connecting sensors and switches, connect terminals that are electrically isolated from the 

respective power and GND. 

•  Do not push the external device I/O terminal button with too much force. Doing so may cause the button 

to remain pushed-in.



 External Device Output Terminals (OUT1, OUT2)

External device output terminals consist of two sets (OUT1, OUT2) of two terminals. The sets 

have no polarity. Controls from the Viewer can be used to open and close the circuit between 

the terminals. Using optical couplers, the output terminals are isolated from the camera’s internal 

circuit.

On resistance: Max. 30 Ω

 Note

Adaptive wiring for external device cables
Solid wire/Stranded wire AWG: No. 26 – 20
Cable strip should be approx. 11 mm (0.43 in.).

Each audio input/output terminal has one input system and one output system.

Connecting the camera to an audio input/output device such as a microphone or a speaker with 

an amplifier allows you to send/receive audio through the Viewer.

Use the included audio interface cable to connect audio input/output 

devices to the camera.

Use the  3.5 mm ( 0.14 in.) monaural mini-jack connector to connect 

an audio output device with the audio interface cable.

The long end (has cable marker) from the bifurcation point in the 

cable corresponds to the audio output terminal. The short end 

(does not have cable marker) from the bifurcation point in the cable 

corresponds to the audio input terminal.



 Audio Input Terminal Common LINE IN/MIC IN (monaural input)

Although the camera only has a single audio input system, it supports two types of microphone 

input: LINE IN and MIC IN. Before using the audio input, please confirm the [Audio Input] in the 

Setting Page (please refer to the “Operation Guide”). LINE IN is selected by default.

Input terminal:  3.5 mm ( 0.14 in.) mini jack (monaural) 

•  Dynamic MIC IN

Input impedance: 1.5 kΩ ±5%

  * Supported microphones: Output impedance: 400 – 600 Ω

•  Condenser MIC IN
