When I said 'what exactly are they not showing' I was expecting a specific scenario that hasn't been done to death, instead the best you could come up with is 'non of them (so far) have shown me enough'.... do you have any clue what you want to see or has this just been a way for you to fill in a few minutes on a Saturday? I've watched a lot of CCTV reviews over recent years, the vast majority tend to cover a range of day/night conditions and various levels of ambient light, IR/onboard light capabilities and where appropriate, audio or AI/NPR, I can't really say i've ever struggled to form a general opinion on the capabilities and suitability after watching a few reviews, but if you can't for some reason, then you're probably going to have to buy/test yourself if your needs are that niche/indescribable.
Personally, I tend to stick to Hikvision for the properties I look after, it's reliable, scales reasonably well across multiple sites, with everything from a single camera with local storage upto a installs with 12+ cameras and NVR's running RAID1 with varying frame rates. Personally, I run Unifi at home, but with a mix of Unifi and Hikvision cameras. If we are talking a single site domestic install with a handful of cameras, i'd happily throw the money at Unifi all day long (stop laughing
@ChrisD. ) It's easy to live with, the app is family friendly, administration is simple and while it's crying out for 24/7 full colour in near zero light rather than IR/B&W (the main reason I run Hikvision ColorVu cameras), it's not been a problem from an evidence perspective when I have been asked for images or footage.
Really? 4 cameras cost £379.20, the NVR lists at £190.80, that leaves £48 for a certified 1TB drive, or 1p more than OCUK will sell you a Seagate 1TB drive for:
Nothing to stop you choosing higher spec camera(s) or a different storage option, but how long are you wanting to retain data for? If it's recording 24/7 you likely have a few months on a 4 camera set-up depending on settings, much longer if it only records when something happens in a defined zone.
