Hikvision have also helpfully started publishing 2 camera features which should be of help to forum members :

DS-2CD2087G2-L(U) ColorVu 4K Initial review of the Hikvision DS-2CD2087G2-L(U) ColorVu 4K

Many forum members are aware that surveillance cameras are installed for a purpose, not to just give a pretty overview picture that turns out to be of no use after recording an incident, so being aware of DORI distances is important. Am very happy with the images apart from the porch camera which is affected slightly by the close proximity of the porch light: It causes a slight purple haze, and darkens the image further out, even thought the light itself is not in direct view of the camera. I need to try and change the porch light to see if I can improve the situation. Lens Type & FOV 2.8 mm, horizontal FOV: 109°, vertical FOV: 55°, diagonal FOV: 138°; 4 mm, horizontal FOV: 94°, vertical FOV: 48°, diagonal FOV: 115°; 6 mm, horizontal FOV: 57°, vertical FOV: 31°, diagonal FOV: 67°OK Video quality. A huge effect on bitrate, from 200kbps to 6Mbps from the lowest to the highest setting. The Day / Night image selection doesn’t actually switch to B&W, despite the related settings still being available, unlike on the G1 ColorVu. This stopped me testing if it still had a fixed IR filter.

Startup and Operating Conditions: -30 °C to +60 °C (-22 °F to +140 °F), humidity 95% or less (non-condensing) Smart Event Line crossing detection, intrusion detection, region entrance detection, region exiting detection (support alarm triggering by specified target types (human and vehicle)) The huge Accusense blob at 50MB+ has meant that Hikvision have stripped out the ‘secondary partition self-repair and recovery’ facility as there just isn’t the needed space even in the 256MB flash memory. What’s probably of most interest is how the camera performs at night, and in particular where the boundary is between being able to squeeze down the exposure to reduce movement blur enough, and still get a usable image, ideally in colour.Smart Event Line crossing detection, intrusion detection, region entrance detection, region exiting detection

Despite the oft-quoted advice on the forum to ‘not chase the mega-pixels’, the combination of the low-light performance and 8MP resolution makes the digital zoom genuinely useful and dilutes that advice in this case. A selection of 4 standard and 2 custom scene profiles for image parameters, which can be set on up to 4 schedules. These are monthly schedules covering a whole year! Power Consumption and Current 12 VDC, 0.5 A, max. 6 W, PoE (802.3af, 36 V to 57 V), 0.2 A to 0.1 A, max. 7.5 W Basic Event Motion detection (human and vehicle targets classification), video tampering alarm, exception Disclosure : The device under review was provided by Andy Wong of @EMPIRETECANDY in exchange for a fair and unbiased review.Using h.265 / 20fps / 8192bps with image parameters at default values and no camera LEDs, I’ve squeezed down the exposure on a fairly low-light scene such that the worst-performing (IPC-T2385G-I) is just not handling the scene well. The breakpoint was about 1/250s.
