Experience 4K video surveillance with the simplicity of reusing existing coaxial infrastructure. The 4K HDCVI camera adopts a powerful Dahua ISP and advanced 1/2.7" CMOS sensor, which provides superior high quality images. In addition, the camera features broadcast quality audio to provide enhanced supplementary evidence collection. Ultra-high definition and a complete set of features makes the 4K HDCVI camera an ideal choice for mid to large-size businesses and projects where both highly reliable surveillance and construction flexibility are demanded.
Features
- 4 Signals over 1 Coaxial Cable - HDCVI technology supports 4 signals to be transmitted over 1 coaxial cable simultaneously, i.e. video, audio*, data and power. Dual-way data transmission allows the HDCVI camera to interact with the HCVR, such as sending control signal or triggering alarm. Moreover, HDCVI technology supports PoC for construction flexibility.* Audio input is available for some models of HDCVI cameras.
- Long Distance Transmission - HDCVI technology guarantees real-time transmission at long distance without any loss. It supports up to 700m transmission for 4K and 4MP HD video via coaxial cable, and up to 300m via UTP cable.
*Actual results verified by real-scene testing in Dahua's test laboratory. - Simplicity - HDCVI technology inherits the born feature of simplicity from traditional analogue surveillance system, making itself a best choice for investment
protection. HDCVI system can seamlessly upgrade the traditional analogue system without replacing existing coaxial cabling. The plug and play approach enables full HD video surveillance without the hassle of configuring a network. - Broadcast-quality Audio - Audio information is used as supplementary evidence in video surveillance applications. The HDCVI camera supports audio signal transmission over coaxial cable. In addition, it adopts unique audio processing
and transmission technology that best restores source audio and eliminates noise, guaranteeing the quality and effectiveness of collected audio information. - Multiple-formats - The camera supports multiple video formats including HDCVI, CVBS, and other two common HD analogue formats in the market. This feature makes the camera compatible with not only XVRs, but also most existing HD/
SD DVRs.
*Use OSD menu to switch HDCVI to other video formats. - Wide Dynamic Range - Embedded with industry leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. True WDR (120dB) optimizes both the bright and dark areas
of a scene at the same time to provide usable video. - Advanced 3DNR 3DNR is noise reduction technology that detects and eliminates random noises by comparing two sequential frames. Dahua’s advanced 3DNR
technology allows remarkable noise reduction with little impact to sharpness, especially under limited lighting condition. Besides, the advanced 3DNR effectively decreases the band width and saves the storage space. - Protection - The camera's outstanding reliability is unsurpassed due to its rugged design. The camera is protected against water and dust with IP67 ranking,
making it suitable for indoor or outdoor environments. Supporting ±30% input voltage tolerance, this camera suits even the most unstable power supply conditions. Its 4KV lightning rating provides protection against the camera and its structure from the effects of lightning.

Easy to use without any effort
Color: Orange
Needed a small space electric opener to help with opening cans due to arthritis. Manual ones were difficult to use. This fits in the palm of your hand and is easy to attach to can. It opens regular size cans easily, although it is a bit slow. The one can it didn't work well on was Fancy Feast Cat Food cans. Seems to leave a sliver of metal on the edge, very tiny but of concern. Contacted customer service and they were excellent - quick responses and very helpful at working with me to see if it was just the fancy feast can or the opener. Seems that those two just don't work well together. They even sent me a second opener so that we could try to recreate the problem. I am keeping the original opener and returning the second one as neither will open the Fancy Feast can. They supplied a return label also. There are lots of cans in the world and this is just a minor function situation with this opener. I think it is a great product.

A very handy kitchen tool.
Color: White
This can opener is an easy, hands free tool, to use. It does open canned items efficiently, but slower than hand-turn openers, which saves a painful wrist motion from which I suffer. Unlike a traditional opener, this one cuts under the can edge which requires caution when removing the lid as exposed cut edges are very sharp. Also, the opener does not stop when it has completed its circuit. The start button has to be pressed to stop action.

Update Year Later, Love it! Really impressed
Color: Orange
Update: I've owned it a year now, still on original batteries (surprised me), it still works great. I still get a little annoyed with how slow it it, but might be time for new batteries. Once in a blue moon the circle is not completely cut, but that's on me as I control when to stop it, to reverse. No issuese removing lid, very smooth. Love it. Original review: I'm pleasantly surprised. It does a great job! Very smooth, safe cut. Who knew? That said, it is much slower than a standard electric can opener, and you have no idea where it's cutting. Now I started on the first letter on the product's label, and pay attention to when the circle is complete. Press the "on" button a second time and it goes backwards for a few seconds. Done! Use the attached magnet to pull off the lid. I'm thinking of buying a second one. Also, I very much like that it uses standard batteries, nothing weird to look for. Well done!

Opener leaves wire threads on the rim of the can when opening. Poses a danger if ingested.
Color: Orange
Purchased this item hoping it would make opening cans easier (I have osteoarthritis in my hands). First time I tried it, after it rounded the lid of a can of DelMonte green beans, nothing. I reseated it, and held it down when it started. It opened the can after circling the top two times. When I took the lid off the can, there were tiny wire "threads" stuck on the can, and more stuck on the Kitchen Mama opener. I was able to very carefully wipe the wire threads off and pour the can of beans into my pan. HOWEVER, I will not use this product again. Who wants to run the risk of ingesting wire threads?!!! I would return the product for a refund, but my husband destroyed the box opening it, so this will go into the garbage. I wouldn't sell at a garage sale or donate it, because someone else might ingest the wire threads, and then Kitchen Mama would have a lawsuit on their hands I wouldn't have given ANY stars, but you have to give at least one to write a review.
