Now is an era with videos and truth. In law enforcement occasions, the on-site recorder worn by law enforcement personnel can restore the process of the matter and provide first-hand evidence for law enforcement. The advantages of recording sites have quickly expanded from law enforcement personnel to many other fields, such as security, window industry, etc. The growth of audio and video recorder market is showing an explosive trend. Today we will bring you iQiyi brand DSJ-KI audio Video recorder experience.
Small and balanced
Previously, we have brought you the experience of a special police recorder product. Considering the possible violent situations of law enforcement, the overall protection of police recorders is better, but this also brings a problem, that is, the product size is too large and heavy. The iQiyi DSJ-K1 is obviously more widespread, so the product is much smaller, but it is still solid enough.
Full-body waterproof and compact iQiyi K1 recorder
Although it is small, iQiyi K1 has relatively good protection, making it full-body waterproof. In addition to buttons, you can also see the expansion card slot and USB at the bottom The interfaces are all waterproof covers and the details are in place. So what is its ability?
inner strength
The performance of the recorder product, the reinforcement of the waterproof shell is only external, and the strength of the inner core is the real skill. The performance of iQiyi K1 has been further improved because it is a new product.
iQiyi K1 uses Omnivision's sensor
The core of the audio and video recorder is the image sensor. The Omnivision CMOS sensor used by iQiyi K1 can take 3600 pixels of still photos or record images in 2560×1440@30P format, which is comparable to the camera capabilities on our mainstream mobile phones.
H.265 encoding has better picture quality and smaller space required
iQiyi K1 comes with a 32G memory card standard, which supports up to 256GB, but the encoder of this product is still for users who do not expand the memory card. Provides H.265 encoding capability. It can be said that K1 is a leading product in the industry with H.265 encoding capabilities, and it can be said to be a pioneer in video recorder products.
Different algorithms have different size settings for the block , and the compressed picture quality and space occupancy are different. H.265 is more efficient
H.265 is the latest compression algorithm in the video field. Videos on computers can be understood as one frame, and the contents of two frames apart generally differ not much. In the H.264 algorithm, the block size of the picture is not flexible enough, but the H.265 compression algorithm supports blocks of different sizes to improve compression efficiency. Generally speaking, videos of the H.265 algorithm have the same resolution and drawing. It takes up about half of the space of H.264. Of course, this is not without cost. H.265 encoding requires stronger computing power, but this is no longer a problem for the encoding processor used by K1. It can still have a very long battery life when compressing H.265.
In the sense of encoding, iQiyi K1 has a lot of space, but the efficiency of storage space utilization is twice that of H.264 coded products. This is where this product is competitive and can be worry-free. Use higher definition image quality to record without worrying about storage.
iQiyi K1 Let’s introduce it to you from several aspects.
Front lens, LED, microphone and status light
First front. The camera is 140 degrees, and 8 LEDs are installed next to it, which can see 6 infrared and 2 visible lights. The two small holes on both sides of the camera are pickup microphones, and the top is a status indicator, one indicates the status of the machine and the other is charging. instruct.
The use of the left key is clear at a glance
The right side is equipped with PTTh key, professional
The key operation on the back of the phone will understand that
The bottom USB interface and TF card slot are equipped with waterproof covers
The left side of the machine is video recording, photography, There are three power buttons, the right side is intercom (PTT), lighting, and recording, the bottom is a USB and TF card slot, and it is equipped with a waterproof cover. On the back there are M menu, page turning up and down, and OK to select four keys and a small screen.
Overall, iQiyi K1 can be used by users within 3 minutes without any difficulty.
Practical experience
Our actual experience is divided into three parts: still photos, night video shooting and dark room shooting.
Taking photos under sunlight is similar to mobile phones, and the lens presents the effect of fish eye lens
static videos during the day we can see that there is not much difference between the photos taken by mobile phones, with high clarity and full and bright colors, and 36 million pixels can also be reproduced. There are quite a lot of picture details. Compared with the photos taken by our mobile phones, the photos taken by iQiyi K1 are more similar to those taken directly without optimization or smearing. This is also the requirement for recording the product: it is more realistic rather than looking better. Since the lens is 160 degrees wide-angle, it has the effect of a fisheye lens, which is a normal manifestation of an optical lens.
You can clearly shoot key information such as license plates in the basement
Videos taken in darker environments, iQiyi K1 can clearly shoot important information such as motor vehicle license plates in the video. This is enough for audio and video recorder products.
All black environment
Open infrared mode, the entire black environment can still take pictures of people
0 We have experimented with infrared shooting ability in the all black evaluation room, and we can see that under infrared rays, we can also take pictures of people in the all black environment.
Experience summary
From the functionality of the product, we can see that the iQiyi K1 product is very complete in function and is aimed at a professional user group, including a very sturdy body, PTT intercom and other functions.
iQiyi is more generous and randomly gave away two breastplate clips
The difference between this product and some police products is that many police products have larger lens angles, while iQiyi K1 is 140 degrees. It is small and does not have hardware anti-deletion, group collection and other functions. The user group is still a field that is not demanding and has no strict requirements on security, window industry and other fields.
actual shooting 1080P, H.265 encoding is about 30M space per minute, 500K per second, very high encoding efficiency
Long battery life and H.265 encoding are the core competitiveness of iQiyi K1's product. The same storage space, longer Storage time makes iQiyi K1 look even more valuable. Because it has PTT buttons, it can be connected to the walkie-talkie, forming a comprehensive video shooting network without dead angles in actual application, which is more flexible than fixed-point cameras.
