I want to monitor the times when my three garbage cans are placed in my driveway and subsequently collected. Each can has a unique six-digit number stamped on the front, along with a barcode. Is it possible to develop a custom model to recognize garbage cans and then utilize OCR, barcode...

I installed a Hikvision DS-2CD2035FWD-I camera (3MP Outdoor Day/Night Bullet 4MM) yesterday on my garage. The picture looked great. This morning I looked, and the picture was all foggy. I inspected the camera and there is now a discoloration on the lens. I tried cleaning it but it's on the...

I implemented a custom DeepStack model to alert me when the mail is delivered because my mailbox is down the street from my home. I'm using a camera mounted near the street that also detects people and vehicles (including ALPR). The post truck detection works but will fail if the event is...

About a 1/3 of my cameras are missing thumbnails on EZViz (Both on the phone app and the website). You used to be able to manually set a cover thumbnail from the website by clicking the Cover button. However, now it returns an error message: "Setting cover failed". The phone app used to...

A few months ago I was on the phone with Hikvision tech support for an IP PTZ camera. The tech used a specific combination of the PTZ buttons to access a hidden menu that provided additional settings not available on the regular web GUI. It brought up a menu similar to the menu found on...

I’ve been experimenting with a motorized 2.8-12mm turret camera. It seems like when the camera is zoomed out it has much less depth of focus than a comparable 2.8mm fixed camera. Is this typical for vari-focal lens?

I have a Hikvision 3MP 16mm EXIR bullet (DS-2CD2T32-I5) on a pole in front of my house for license plates. It was working (not great but legible for most plates). Not sure what happened but now the plates are all over exposed at night. Before: After: It still works adequately during the...

How do you calculate the bandwidth of an HD-TVI camera? I'm looking at a Hikvision DS-7216HUHI-F2/N Tribrid DVR. It's maximum incoming/outgoing bandwidth is 128 Mbps. I want to use 16 HD-TVI cameras (2MP 30FPS and/or 3MP 15FPS) and 2 3MP IP cameras.

I’m upgrading a system where I can’t change the coax wiring. The user wants 16 HD-TVI cameras and 2 interior Wi-Fi IP cameras. I’m going to use a Hikvision Tribrid DVR (DS-7216HUHI-F2/N). The Hikvision HD-TVI cameras come in 3MP 15FPS or 2MP 30 FPS. What do you guys think would give a better...

Anyone know if you can change the lens on the Hikvision 4k bullet cameras (DS-2CD4A85F-IZ). The stock 12mm is not giving me enough zoom in ability.

I have a Hikvision PTZ IP camera (DS-2DF8236IV-AEL). Is there any way to reduce the sensitivity on the Smart Tracking. I just want it to track people and cars, but it zooms in when the wind blows a leaf.

Is this a stuck IR filter? The camera is a HikVision DS-2CD2532F-I-2.8mm IP mini dome camera. It was working great for about 3 months.

I have a Hikvision DS-2CD2032-I-4MM with a lightly scratched lens. Someone tried to remove a spider web with a stick. It's not too bad during the day but at night the IR lights them up terribly. Are there any products to remove scratches that work? Can you buy a replacement lens? I remember...

I'm trying to find the firmware for an AvTech Model G4-HD4E (part # 1.1.03.51.0121). It might be an older rebranded Dahua (not sure).

From reading this forum, it seems like dome cameras are often not recommended for outdoor use. Yet, it seems like many of the higher end outdoor cameras are dome (not including box cameras). I’m in a hot sunny climate. I wanted to use a PTZ pendant and another vandal proof fixed dome on a...

What is the main purpose of camera heaters? Are they for picture quality and lens defrosting or to protect the electronics and moisture? Are they worth paying extra for and are there any downsides?

We recently had a package theft in front of our house. The thief walked right in front of the camera, but the recorded footage is useless (see pics). I’m looking for a replacement camera that would provide a very high quality image day or night. The current camera is an ADT turret...

We've been having a lot of packages stolen in our neighborhood. I’m looking for a high quality IP camera to capture cars and license plates day or night. The camera would be mounted 4 feet back from a 2 lane road on a pole (speed limit is 25mph, law requires front plates). I see that a lot of...
