Review: Hikvision DS-2CD2035-I

Those QD900s are getting hard to come by. Often $60 or more now IF you can get them. Plus I've learned of a security flaw in them recently and they do not offer firmware fixes. On a suggestion in an IT forum I looked at the Hikvision cams. The Hikvision DS-2CD2035-I  is a damn nice 2K 70 deg view cam I got for $80 but you do not get WiFi in this model and it is not upgradable. There is sticker on the box warning you not to try in fact which is bit of a red flag for people that are aware of IoT security issues that have been making regular news of late. Fortunately look for the US or upgradable version in the descriptions on Amazon.com for one you can get firmware update to. They seem to be running about $20 more for the same features though. If not worried about your network security, it still compared well with a Escam Qd900 that is running only about $20 less. For that $20 you get a lot more detail and probably are still more secure but you do loose wi-fi. You also get config and monitoring features you do not normally find in low cost cameras like SNMP v3.

I also like the mount better on the Hikvision. Another nice thing about the Hikvision cams is most of them are available with 2.8, 4 or 6 mm lenses so you can probably get one that matches the viewing angle you need without needing to swap out the lens.

All the pics here were grabbed from the video recorded on Blue Iris using this config

In a posted pic you will not see a lot of diff in a day time shot between the 2K Hikvision w/ 4 mm lens
and the 1080p QD900

If you zoom in though you see a huge difference between the Hikvision
and the QD900

Night vision is not bad. Note the plane in the upper right corner.

though the you are not going to get much detail at 50 feet without extra illumination on a moonless night.
Here is a quick IR sensitivity compare contrast left to right the Hikvision, the $40 (referb) Foscam FI9804 and  the $40 SV3C I had next to each other for evaluation. Note the Foscam is picking up some IR bounce back from the fence in front and below it even though the fence is not in the picture.

Inside it looks like this

It is hard to make out but this lens is glued in place making it impossible to swap out.

  5. Positive site, where did u come up with the information on this posting? I'm pleased I discovered it though, ill be checking back soon to find out what additional posts you include. Serious Security Melbourne

  6. Unfortunately these posts are mainly my attempts to get some detail missed after something happened the next time. There is a lot of bad info floating about. From people saying things like you can do face recognition of people at 100 feet with 1080p / 160 degree view cams or a tracking cam can cover the same area as multiple cams to people saying any cam under $500 is useless. Hopefully these posting of my adventures will so what it realistically possible on a budget and save others from wasting time, money and disappointment of not getting the shot they expect.
