Which brand is good for Body camera?

Body camera is derived from the evolution of tachograph. There is no need to focus on brands in this industry. Unlike consumer electronics giants such as Apple, Samsung and Huawei, they are basically made in Shenzhen, China, focusing on integration. The so-called XX brand is just an OEM. Therefore, the selection of body camera source depends on the cost performance, as follows:

Qualification certificate

3c is a compulsory national security certification to ensure your basic security. CE is required for overseas

Network format

There are stand-alone versions and 4G versions. The stand-alone version is basically used without network. The number of recordings is small, the requirements for file management are relatively small, and the functions are relatively simple and affordable; The 4G version is generally equipped with a platform, which can provide track playback, electronic fence, real-time video, intercom, remote monitoring, patrol and other rich functions. Of course, the price will also be high, and the general platform software will also be charged annually

Assembly line mode

The assembly line mode of the body camera is generally fixed on the personnel on duty. Now there are crocodile clips, electromagnetic field back clips, shoulder clips and other spare parts on the market, in which the electromagnetic field back clips are more solid and generally cannot be dragged out.

Number of surveillance cameras in Shenyang

Generally, many people submit orders for shooting, double shooting and triple shooting for body camera. Among them, three Shenyang surveillance cameras are more versatile. One is used for self portrait and cooperation; One main camera of the rear dual lens is used for video recording and one sub camera is used for photo shooting. This scene is applicable to the effect that the management background can open the camera when the video monitoring system is recorded in time.

Appearance specification and model

The standard specifications and models are all super small, medium and small. The advantages of super small are portability, obvious defects, and small battery capacity. Plug in rechargeable battery can be fully considered for standby if it is used continuously for a long time

Display Size

1.5 ", 2.0", 2.4 ", no display, etc. Generally, 2.4 is the main product, which can be touched. This also depends on the application scenario

storage space

Generally, the body camera is not embedded in the operation memory, and needs to be expanded by the memory card. In case of MicroSD card expansion or SD card expansion, the capacity is 8G, 16G, 32G, 64G, 128G; It can be more customer-oriented video storage regulations. According to its own configuration, the larger the storage, the higher the price of the body camera. Generally, it is necessary to manage the purchase according to the quality of the body camera video and the record storage of the Shenyang surveillance camera. The high-definition body camera has 720p and 1080p, and the 16G card with 720p video can only record video for about 4 hours, 1080p video occupies twice as much indoor space as 720p video. It is also generally required to select the high-speed card class10 for the memory card, otherwise the video recording will be interrupted.

Video Pixels and Format Files

The pixel and frame flow rate of audio and video files is an important indicator to consider the image quality of the body camera. The body camera market is mainly divided into four categories: high-definition, high-definition, ultra clear and ultra clear. The high-definition body camera has 720p@30FPS 、 720p@60FPS 、 1080p@30FPS 、 1080p@60FPS Yes, ultra clear 1296P@30FPS 。 The format files available in H.265 are better than those available in H.264. In the case of the same image quality, H.265 occupies less indoor space. Of course, the comprehensive service platform must be able to analyze H.265 format files before they can be played. There are still some computer consumer playback software that do not allow H.265 analysis.

Capture Pixels

Generally, there are several kinds of shooting pixels: 90 degrees, 100 degrees, 120 degrees, 140 degrees, 150 degrees, 170 degrees, etc. The body cameras of the main products are equipped with 120 degree or 140 degree ultra wide angle lenses. A single ultra wide angle lens can hardly reach the 170 degree ultra wide angle lens. Even if the 170 degree page is guaranteed, it will be severely deformed, which will damage the clarity of the page.

Video picture quality

According to the picture quality, Body Camera has four kinds of picture quality: 300000 picture quality, 1.3 million picture quality, 2 million picture quality and 5 million picture quality. Some of the pictures marked as 12 million, 36 million and 48 million picture quality refer to static photography, not video picture quality values.

Current quality assurance policy

There is no doubt that this is the top priority. Try to choose network platforms. It is better to have third-party monitors. Or it is better under the binding force of the contract.

Conclusion: Shenyang surveillance camera should have greater shooting skills, which is conducive to recording the surrounding conditions in multiple directions. However, it should be noted that the angle of the ultra wide angle lens should not be exaggerated to prevent the page from being distorted.

Body camera should have very good shooting quality and professional ability to shoot at night. The high-definition is managed and decided by the main control chip of the body camera. In this case, the car owner must pay attention to the image processing plan of the main control chip of the body camera. That is, the body camera needs sufficient storage space to maintain long-term effective shooting.

The main product image processor format files are MOV, avi, H 264 format file. If the body camera cannot reach 30 frames per second, the video will crash under the 1080P shooting method. Under the 720P shooting method, at least 24 frames per second that the witness's eyes can blend into, can we see the smooth and clear video page.

According to the regulations of the Body Camera of the National CCC Certification Quality Management Center, they can be sold in the market after passing the 3C certification as far as possible. Therefore, when choosing famous brands, store buyers must be careful to purchase products manufactured by reliable manufacturers with 3C certification to ensure safety.
