Bunker hill security dvr put videos1/8/2023 I would recommend avoiding the HIK completely. If you're on the fence about getting one of these 1/1.2" sensor cameras, I would wait until Dahua offers a longer lens on this model, or wait for a varifocal model. I can confidently say that Dahua comes with the Sony IMX485 and the HIK comes with an unknown clone, which explains the poor performance. A little digging led me to pictures of an actual IMX485. While doing so, I noticed that the sensors are completely different, though the same size. I decided to take the lens off the HIK and put it on the Dahua. Looking at the market for these cards, you may pay. I recommend at least a Class 4 card but ideally a Class 10 which is at least 10 MB per second. Class 4 provides at least 4 MB per second, and Class 6 is 6 MB per second. The HIK is a poor performer, but has a beautiful 6mm F:1 lens. Most of the home security cameras manufactured over the past few years have high definition capabilities of 720p or higher. The Dahua turned out to be a stellar performer, but the lens sucks. A lot of people just assumed that these cams came with the Sony Starvis IMX485. While both of these cameras claim to have a 1/1.2" sensor, neither manufacturer explicitly states that the sensor is a Sony Starvis. I also decided to try the HIK DS-2CD2087G2-LU, with the 6mm lens, which also has a 1/1.2" sensor. I recently got the Dahua IPC-HFW5849T1-ASE-LED with the 3.6mm lens, as that's the longest lens available at the moment.
