105mm cannon shell
50mm anti-war cannon
During World War II, the German Type 38 50mm anti-tank gun was developed in 1938. It was 4.75 meters long, 1.85 meters wide, 3.137 meters long, and weighed 813 kilograms. The number of cannon crew members was 4 - 6. This was the successor to the 37mmPak 35/36 anti-tank gun, which had been produced since 1940. It was the same as the 60 times diameter 50mm gun used by the later Type J of the No. 3 Tank in 1941. In terms of armor penetration, it could penetrate 88mm at a 250m angle and 78mm at a 500m angle. When fired at a distance of 914m, it could penetrate an armor plate with an angle of 30 degrees and a thickness of 50.8mm. As the angle increased, the armor penetration thickness would also increase greatly. This type of cannon had a very low profile. If the cannon bunker was more than 0.61m, then the cannon body would almost stick to the ground, so the entire cannon position was difficult to discover. Its technical data was as follows: The caliber of the cannon was 50mm; The cannon was 4.75 meters long, 1.85 meters wide, and 1.05 meters high. The barrel was 3.175 meters long, and the rifled barrel was 2.824 meters long. The cannon was heavy, weighing 990 kilograms in battle and 1000 kilograms in transportation. The firing range of the cannon was 60 degrees, and the firing angle was-8 to 27 degrees. The firing rate was 12 to 14 rounds per minute. The longest range was 9400 meters, and the longest aiming distance was 1000 meters. The effective range was 700 meters.

Wrath 457mm
HMs Furious was equipped with a 457mm (18-inch) main gun. These main guns weighed 827 tons with turrets, and the super-heavy ammunition used weighed 3320 pounds (1506 kilograms). The muzzle velocity was 2270 feet (692 meters) per second, and the maximum range was 28,900 yards (26,430 meters). Using a 1506 kg super-heavy armor-piercing bullet could penetrate 457 mm (18 inches) of protection within a range of 13720 meters, and using a 1633 kg ordinary shell could also cause 373 mm (14.7 inches) of armor-piercing effect within a range of 14630 meters, but the recoil was extremely high.
The Wrath was originally the Braveheart class "Large Light Cruiser" No. 3. Construction began on June 8, 1915. It was launched on August 15, 1916 and entered service in July 1917. Initially, it was designed to carry two single-barrel 18-inch (457mm) heavy cannons. With the Royal Navy's exploration of ship-borne aviation, it was modified during construction. After completion, the single-barrel 18-inch cannon at the stern was retained, and the bow cannon position was changed to a hangar that could accommodate 10 aircraft and a flight deck was laid. In 1921, the main cannon at the rear was removed and transformed into the front and rear flight decks, which were responsible for take-off and landing respectively, while the bridge and chimney were retained in the middle. During the Second World War, the ship was mainly used in auxiliary combat due to its old hull, and some modification work was carried out. It was sold and demolished in 1948.

Mm, playing in the stream
If you want to play in the stream, you can consider the following locations: Taihe Baishan Village, Baiyun District, Guangzhou. Driving to Baishan Village, it takes about 1 hour to reach in Guangzhou City. It takes about 3 - 5 minutes to walk from the parking lot at the entrance of the village to the water play spot. You can navigate to "Yihe Village"(located in Baishan Village). The stream here is clear and shallow. You can see many small fish. You can bring your own slippers, fishing nets, water guns and other small toys. There is a pavilion next to it for a rest and picnic. Surrounded by green mountains and trees, there are greenways for walks. Near the ecological design town of Conghua in Guangzhou, it was 1.5 hours 'drive from downtown Guangzhou. Near the bus station of Luo Village in Liangkou Town, you could see the tents set up after parking the car and walking along the green road. The stream here was cold and clear, and you could fish and shrimp, play with sand and stones, etc.
It was important to note that there were certain dangers in playing with water in a stream. For example, a seemingly calm stream might hide hidden dangers such as mountain torrents and mudflows. If you heard rustling or roaring in the valley but could not find the source, you could sometimes feel a slight vibration. This could be the sound of loose sand and flowing water, usually a signal that mountain torrents or mudflows were forming. If the water level is rising rapidly, the flow rate is obviously increasing, or there are more firewood, trees, and other floating objects in the water, they must move quickly. If you were unlucky enough to encounter a flash flood, you should try your best to run ashore and fight for the "golden time" to escape as fast as possible. When escaping from the disaster scene, you should choose the nearest safe route to run horizontally along the hillside. Do not run down the hillside or downstream along the valley exit. The flash flood flows fast and rises quickly. Don't easily swim away to prevent being washed away by the flash flood. Call the rescue phone as soon as possible and wait for rescue. At the same time, during the summer vacation, parents should take on the responsibility of supervision, strengthen drowning prevention education, improve their children's safety awareness, and warn their children not to play by the river, sea, or lake to prevent drowning accidents.

Surveillance camera 12mm
He only mentioned that the "surveillance camera 12mm" was rather vague and did not know the specific content of the problem. If it was a surveillance camera with a 12mm lens, from the reference, the surveillance camera with a 12mm lens could monitor a distance of 50 meters. For example, there was a 1200-line security equipment infrared night vision surveillance camera, and a high-definition array camera was a 12mm lens. The reference price was 388. Different focal lengths would affect the field of view of the camera. The 12mm lens was a telephoto lens, suitable for long-distance shooting and able to see details in the distance. However, it might not be suitable for indoor surveillance. Usually, 2.8mm or 3.6mm lenses were chosen indoors. If it was outdoor monitoring and needed to monitor a long distance, a 12mm lens could be considered. At the same time, when choosing a surveillance camera, in addition to the lens, it was necessary to consider the networking method, the resolution, the video storage method, indoor and outdoor use, the power supply method, the voice intercom, and many other factors.
