Hikvision PTRZ Dome Cameras

[GentlePumpkin]

New ptz cams in a slightly larger dome housing: DS-2CD2746G2H - Interesting...

But then the datasheet says: Max 1000 ptz cycles. Is this the expected time to mechanical failure?


And miraculously 4, 6 and 8 MP all have the same sensor size

Also available as hybrid (ir/white light) where half of the ir leds are replaced by white light. I've got careful with Color night vision since the image in my experience is most of the time way more "washed out" then Ir illuminated images.

So night-image wise the 4MP would be most interesting. I don't trust the 0.0008 Lux at all since even among Hikvision product these ratings are completely inconsistent in my experience.
I haven't used domes outdoors to omit the reflection risk. Did that get better? With these models they advertise "moving" light shades.

Price ranges around 280 USD.

• I'm interested in your thoughts on this.
• Maybe you already had hands on these new models.
• what average use case cams would you select from Hikvision portfolio today?

Yes the 1000 cycle will lead to mechanical failure as i got the information. This is expected lifespan of either motor or rubber. Eitherway these are not meant to work as standard PTZ cameras, this options are presented only as installation time saving for image angle corrections.
The hybrid option is already well known 2nd generation of G5 platform cameras.

Dome for outdoor? I would never use Dome for outdoor and i will always go with turret or bullet.

The ones that i can suggest are:

DS-2CD2387G2-L (ColorVu 8MP 1/1.2 sensor size)
DS-2CD2347G2H-LIU (4MP Hybrid IR/White light 1/1.8 sensor size)

These are my go to cameras.

Cheers

If you don't need auto-tracking, DS-2CD2787G2H-LIPTRZS2U/SL is one of the best option of Dome Camera.

• Image Sensor: 1/1.8" Progressive Scan CMOS
• Min. IlluminationColor: 0.0028 Lux @ (F1.2, AGC ON),0 Lux with light
• Motorized Pan, Tilt, Rotate, Zoom for easy installation and monitoring
• 24/7 colorful imaging via ColorVu technology
• IR light & White light & Smart Hybrid Light modes
• Human and vehicle classification based on deep learning
• Built-in arrayed dual-microphone for real-time high quality audio security
• Active strobe light and audio alarm to warn intruders off
• Water and dust resistant (IP66) and vandal resistant (IK10)
• Audio and alarm interface available

Let me explain the reasoning for the PTRZ. The downside of using a traditional dome camera is that in order to install, you need to take the dome off. If the dome comes off then you will get dust, moisture, fingerprints, etc inside which most people fail to wipe off. Before the camera's domes are put back on, need to adjust the angle by moving the lens itself. There is just more room for error which affect reliability. With the new PTRZ, the dome is not removed during install. There is a plate that disconnects from the camera that attaches to the surface first and the networking cable is fed through. Then the wiring is connected to the camera and the camera is snap into place on the mounting plate. Use the PTZ controls to adjust the viewing angle. Can adjust left, right, up, down, zoom in, zoom out, clockwise, counterclockwise. These motors for the adjustments are made for those initial lens adjustments and not to be used as a standard PTZ even though it has the motors to do so. They were not made for that many movement cycles.

Interestingly on the design of the camera, if water was to get inside the base/harness portion... they have put weep holes so the moisture can drip out. If I was to nit-pick, the clips that hold the camera to the base seem to be made of a sort of plastic. There is a locking screw that secures it into place though. The mounting base is an aluminum allow with a silicone wrap. I would say you are able to put all the wires into the area between the mounting base and camera so there is not a need for a junction box.
