How to install Dahua Thermal Hybrid Bullet Camera TPC-BF2120-T

The Chinese manufacturer Dahua offers this dual lens, fixed bullet camera as a comprehensive answer to both indoor and outdoor surveillance needs. The strength of this device is the combination of visible and thermal technology that makes it a suitable solution to monitor dark, small areas. The thermal lens of the device works in complete darkness while the visible lens functions to register details.

The first thing to consider is the location for installing the camera. Ensure that there is enough space to fit the camera and that the wall and bracket is strong enough to hold the weight of the device. The company recommends the wall to have a safety factor of 8 times.

Prepare the cables

There are three kinds of cables to prepare. Power cable, signal cable, and video cable. When selecting the power cable for extension, there are certain recommendations that can be followed. Please see the table below to get an idea of the maximum transmission distance for wires of specific diameters, with DC12V transmitting at 15W.

Diameter of the wire in millimeters Maximum distance in feet and meters
2.000 40.71 (12.41)
1.250 99.39 (30.29)
1.000 63.61 (19.39)
0.800 40.71 (12.41)

 

When selecting the signal cable for purposes such as audio, RS485, alarm output, and input, etc., a width of 0.56 mm (24AWG) or more is ideal. For video, a full cable with copper conductor, 75-ohm impedance and 95 percent knitted copper shield is suggested. Please see the table below for more information.

  1. The first step is to fix the device on the location where you have decided to place it. In the accessories bag, you will find the installation map. Paste it on the surface where you intend to mount the camera. This could be a wall or the ceiling. Drill holes in the designated places on the map.

Find the expansion bolts in the accessories bag and insert them into the holes that you just drilled. Next, get the self-tapping screws from the accessories bag. Align the mounting holes on the device bracket chassis with the expansion bolts that have already been inserter well. Finally, with the self-tapping screws, fix the device on to the surface where you want it mounted.

  1. With the requirements in consideration, connect the external cable.
  2. Consider the angle at which you want the camera to remain. Adjust this accordingly by first loosening the adjusting screws with an inner hex screwdriver and tightening them back once you get it to the right angle.

  3. If your device is placed outdoors, use a waterproof connector for the network port. To do this, first, place the rubber ring into the network port with the smaller hole facing outward. Then insert the fixing rubber ring into the main part of the waterproof connector.

Bring the network cable without the crystal head through the waterproof connector, fix the rubber ring and the waterproof fastening cover. Connect the crystal connect to the network cable. After this, insert the waterproof connector to the network port and rotate it clockwise to lock it firmly. Similarly, bring the waterproof fastening cover over the waterproof connector and twist it clockwise, to lock them together.

Configuring the network

All Dahua cameras come with the same default IP address, which is 192.168.1.108. To ensure smooth operation of the camera, plan the IP segment after considering your local network settings. On wired cameras, IP address can be modified easily either by using the “Quick Configuration Tool” or by using a web browser.

Using the Quick Configuration Tool

 Open the Quick Configuration Tool by double-clicking the file configtool.exe. Click the IP symbol to open the interface that lets you change the IP address and then click on “Search Setting”. This will open up a window where you can set the device’s IP segment and enter the username and password. The default username and password are “admin” for both. Click OK and the software will identify devices within this given IP segment.

From the devices that are identified, select the one of which you want to change the IP address. Then click the button that says “Batch Modify IP” to open another window. Here, set the mode as “static” and enter the planned start IP, subnet mask and gateway. However, remember that if there is a DHCP server in the network, the mode should be set to DHCP. The device will get an IP address automatically in this case. Click OK to finish the work.

Using web browser

Open Internet Explorer and input the camera’s IP address in the address bar. In the login interface that opens, enter the default username and password, which are both “admin”. This will open the main web interface wherein you can change the IP settings. Note that the interface would ask you to change the default password on entry, which is a good practice for cybersecurity.

Enabling Fusion function

One of the most attractive features of this camera is its ability to combine both thermal and visual channel and present it as an overlay. To enable this function, go to Select>Camera. In the settings window that opens up, change the mode to “Fusion”. Click OK to complete the process.
