Don’t be afraid of being soaked in water and dropped. This IP68 three-proof smart intercom mobile phone is made in China.

IT168 Review Speaking of rugged mobile phones, I believe many old players will think of Sony Dafa L36h and the classic Motorola defy. However, in front of this IP68 three-proof mobile phone that the editor got today, it looks "broken". CONQUEST S8 is a military-grade three-proof smartphone that not only supports IP68 three-proof, but also has functions such as hardware intercom, Beidou + GLONASS dual-mode positioning, and an external infrared night vision camera. According to the official introduction, this mobile phone can even be customized with Category 1 and 2 intrinsically safe explosion-proof models and MA coal safety explosion-proof certification according to user needs.

It supports users to customize the outer packaging, body appearance, and body performance, which is unique among professional smartphones.

As an IP68-rated three-proof mobile phone, the outer packaging of CONQUEST S8 also adopts a waterproof design. In fact, this package can also be used as a toolbox for accessories or small items. After all, this phone has many accessories. CONQUEST S8 comes in two colors: yellow and black, which can meet the individual needs of different users.

CONQUEST S8 uses a 5.0-inch 1080P screen and is covered with high-hardness fourth-generation Corning Gorilla Glass. The front camera has 8 million pixels, ensuring the quality of outdoor video calls.

Although IP68 three-proofing has higher structural requirements for the fuselage, CONQUEST S8 still has all the functions. In addition to the 16-megapixel camera, it is also equipped with a 110db high-volume external amplifier, a high-power LED flash, and an NFC chip.

As a professional mobile phone, CONQUEST S8 has all the express buttons. The magnetic charging interface can also be used to connect external accessories such as cameras and microphones. These buttons and interfaces are all designed with three protections, so users can use them with confidence.

CONQUEST S8 also adds a fingerprint recognition function on the left side of the fuselage. It also has a three-proof design, so it is not afraid of water or dust. Careful friends will see that the entire body of CONQUEST S8 is covered with shock-absorbing material, especially the four corners, where the buffer area is thickened. The speed of fingerprint recognition is good, and the position is also in line with ergonomic requirements.

CONQUEST S8 comes with many more standard accessories than ordinary mobile phones, from charging stands to magnetic charging cables, intercom antennas, hand straps, waist clips, etc., which are suitable for different environments such as outdoor and industrial environments. of matching.

CONQUEST S8’s headphones and USB interface are covered with waterproof plugs, so a charging stand is necessary. Because frequently opening the waterproof plug will reduce the waterproofing effect. The charging stand is also convenient for users. They can charge the phone just by putting it in, eliminating the trouble of unplugging and plugging in the charging head.

As for the magnetic charging data cable that comes standard with CONQUEST S8, it provides convenience in terms of portability. After all, the charging stand is not convenient outdoors or in the wild, but the magnetic charging data cable is not only easy to carry, but can also be connected to a mobile power supply.

For better three-proof performance, the CONQUEST S8 with a built-in 6000mAh battery is larger in size than an ordinary mobile phone. Therefore, it comes standard with a waist clip and hand strap, which means CONQUEST S8 is more suitable for attaching to a belt or backpack. The standard waist clip is a quick-installation design, so the clip does not need to be removed during use.

There are buckles on the top and chin of the back of CONQUEST S8, which are used to install the hand strap. The hand strap can make the grip more stable and reduce accidental falls, or it can fix the fuselage in special locations such as tree trunks and telephone poles.

CONQUEST S8 supports full Netcom 4G dual-SIM dual standby, and the primary and secondary SIM cards (primary SIM card for Internet access) can be freely switched within the system. Although the fuselage already comes with 64GB of storage space, CONQUEST S8 additionally supports memory card expansion. As for the key pick included in the accessory, it is used to open the card slot compartment. Because the card slot compartment uses a waterproof sealing ring, the screws need to be tightened hard.

Professional function experience One of the highlights of CONQUEST S8 is that it supports a variety of extensions, such as hand microphones, night vision cameras, etc. (need to be purchased separately). What the editor got is an infrared night vision camera, which can be used after installing the APP. CONQUEST S8 will display the image in real time, and when the night vision mode is turned on, the camera automatically switches according to the ambient light. There are screw holes reserved on the magnetic interface, which can be fixed very tightly. The infrared night vision camera has a switch control and can be turned off when not in use to save power. The effect of this external infrared night vision camera is good, mainly reflected in the clarity and low-latency image transmission. This night vision function is very practical during outdoor activities, because the image is displayed in real time. In addition to monitoring and recording, it can also be used as a lighting facility when traveling at night. CONQUEST S8 supports hardware + POC intercom. You only need to connect a dedicated antenna. The phone itself already comes with an intercom APP. CONQUEST S8 can talk to ordinary walkie-talkies, using a 2-watt U-band frequency of 400-480MHz, and the theoretical intercom range reaches 2 kilometers. The editor and colleagues experienced it in an office building within a 100-meter range and found that the communication picture quality was quite clear. According to the user's environment, CONQUEST S8 can adjust the parameters of the intercom mode in detail and add specific channels. It is more intuitive to use than traditional intercoms. As mentioned before, CONQUEST S8 has built-in Beidou + GLONASS dual-mode positioning. If you don’t try it, you won’t know how awesome it is. Even when there is no network, the satellite signal can be positioned immediately from indoors to outdoors. Using the built-in APP, precise longitude, latitude and direction can also be identified. In addition to fast positioning, the positioning accuracy of CONQUEST S8 is also quite good. The editor's own mobile phone used network positioning to drift to a nearby hotel.

CONQUEST S8 also comes with air pressure, temperature, and altitude sensors, which are very important data for users who like outdoor adventures. The signal is often poor outdoors, so the fuselage comes with more functions to allow users to quickly find solutions when encountering emergencies.

Violent test IP68 is the highest level of connector waterproof rating standard. To evaluate the dustproof and waterproof performance of waterproof connectors, it mainly depends on the last two digits of IPXX. The first digit is the dustproof level, from 0 to 6, the highest level is 6; the second digit is the waterproof level, from 0 to 8, the highest level is 8. The official test data is immersion in 1.5 meters of water for 30 minutes. However, the editor did not have a 1.5-meter-deep pool, so I found a fish tank and soaked CONQUEST S8 for an hour. After an hour, I took out the CONQUEST S8. I didn’t have time to wipe off the water and turned on the camera to see if the machine was normal. In fact, the editor is not too worried, because the CONQUEST S8 looks very reliable. The machine was used normally, and the editor then looked at the interface part protected by the waterproof plug. Under the influence of water pressure, the waterproof plug on the chin showed traces of water after being soaked for an hour, but it did not enter the interface. Because the IP68 standard requires soaking for 30 minutes, the editor has exceeded 100%, so I am very satisfied with the waterproof performance of CONQUEST S8. After running in the water, the editor immediately took CONQUEST S8 to the balcony. The reason why I chose this place is because the cement floor is harder than asphalt and mud. During the test, the sound of the fuselage hitting the ground attracted many onlookers. After repeatedly throwing the CONQUEST S8 for more than ten times, you can see that there are some scratch marks on the cushioning casing, but there are no obvious signs of damage to the phone itself, such as the screen.

Entertainment/Performance

Although it is positioned as a professional rugged mobile phone, CONQUEST S8 does not neglect entertainment functions. The CONQUEST S8 in the hands of the editor is a high-end version with a built-in eight-core processor, 4GB of memory and 64GB of storage space. With ample memory and a 5-inch 1080P screen, you can watch movies during outdoor activities without any pressure.

With this performance, it is no problem to play Honor of Kings. Of course, medium and low image quality will be smoother.

Moreover, CONQUEST S8 has a built-in 6000mAh battery, which consumes about 6% of the power in 30 minutes (50% brightness). In addition, S8 supports OTG to power other mobile phones, which can be used for emergency purposes.

As for taking pictures, the CONQUEST S8 uses a 5-megapixel + 16-megapixel camera combination. The image quality is quite satisfactory and the colors are relatively bland, but the details brought by the 16-megapixel are still sufficient.

Experience comments

As a professional mobile phone, CONQUEST S8 has IP68 waterproof, dustproof and drop-proof performance, and can face complex outdoor or industrial environments with ease. The appearance of CONQUEST S8 is more portable and beautiful than ordinary rugged mobile phones. At the same time, the packaging, LOGO, nameplate, power-on screen, and system can all be customized according to user needs.

Compared with other rugged mobile phones, CONQUEST S8’s ability to expand functions is undoubtedly a highlight. For example, the addition of an infrared night vision camera greatly enhances the S8's observation capabilities at night and in narrow locations. I believe that with the continuous development of official products, more plug-in accessories will be added.

CONQUEST S8 is equipped with an eight-core processor, equipped with 4GB memory + 64GB storage, and has a built-in 6000mAh battery. Make the whole machine run smoothly, interact easily, and respond quickly. In particular, the long-lasting battery life allows users to avoid the worry of insufficient battery when working outdoors and traveling.
