The Hikvision EU portal has a newer version IPCH_EX_G3_EN_STD_5.5.153_200730 which may well change or fix some of the observations below. 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.

Together with high-end Hikvision memory card, memory card encryption and health detection are supported Then I’ve dropped the exposure to 1/500 and 1/1000 so the 4MP and 8MP ColorVu cameras can be compared. This is an initial review of the interesting Hikvision DS-2CD2347G2-L(U) 4MP IP turret camera, linked to the marketing terms ColorVu 2.0 and Accusense 2.0The camera isn’t correctly reporting Smart Events to the NVR or management system. While VCA data is being passed over correctly, intrusion detection and line crossing detection are labelled as motion detection. This doesn’t seem to depend on the active codec. Tested via DS-7604NI-K1/4P with 3.4.103 firmware. You had mentioned the low illuminance setting. I remember seeing this when I first powered the camera up but now can’t find it... Other than exposure time what else changes in the image? It’s not a totally even comparison as the DS-2CD2087G2-LU camera has a 6mm lens, the others have a 4mm lens.

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 There are a number of scale expansions to otherwise existing and familiar configuration settings that should help users to fine tune the camera for their use case.

This stopped me testing if it still had a fixed IR filter. I have 3 ColorVu‘s covering the front of my property and a relatively well lit scene via street lights but the local authority do turn them off between fixed hrs, so that is when I enable the cameras own LEDs to turn on. I also have a porch light which is on from dawn to dusk.

At the time of writing, the Hikvision EU and UK firmware portals don’t seem to have caught up with this model. The firmware has some rough edges, so there should be some updates out soon.

Smart Event Line crossing detection, intrusion detection, object removal detection, unattended baggage detection, Face Detection The ‘low illumination’ scene makes interesting changes to the image, but the default exposure of 1/6 could also mislead if not noticed. This was OK via the web GUI, and OK after using the upc (don’t try this at home) command at the bootloader. It may depend on the specific method used to ‘reset to Inactive’. In the parallel post for this type of camera, spammenotinoz asked me to post a BI stats clip ( Hikvision ColorVu + 4K (DS-2CD2087G2-L)). I note you don’t use BI but if you look at that, although I now realise there are no column headings, it shows (for my fps of 10), the key frame (i-frame) rate from the camera is wrong (10.02/0.1) (10 seconds). It’s set at 20 in the camera and so should be 0.5/s. I recall 50 is the default. We can conclude, therefore, that as well as CBR/VBR, several parameter settings in the ‘Video/Audio’ tab are ignored. 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 WBeing unfamiliar with Hikvision, there are quite a few settings that I don’t know what they mean and I may ask for an explanation in due course if that’s OK... The low-light performance is very similar to the familiar DS-2CD2347G1-L(U) ColorVu camera. It uses the same type 62 sensor. Comparison shots (plenty of these in other threads) -
