is there a longer inspection cable available

Asked by Darryl September 6, 2019

Is the camera cable semi ridgid or limp

Asked by Jo May 20, 2019

Hello Jo and thank you for the question. The camera cable is semi-rigid so it can stand up and shift to whatever angle you need. Thank you!

Does the inspection camera come with a battery and charger?

Asked by joe February 6, 2019

It comes with a charger battery. It has been very useful for me.

What is the resolution of the system? The Ryobi team said the camera had 300,000 pixel resolution...

Asked by RJJ January 17, 2019

This product's camera resolution is 300K pixels.

I charge the battery and I put it back inside and nothing came on I checked the battery again on the charger

Asked by Jose December 13, 2018

I have a similar problem. After three (3) uses the device would not power up. I purchased a new battery and this did not help. I tried to contact Ryobi a number of times by phone and was greeted with, "we are experiencing unusually high call volumes." I gave up in frustration each time. I hope you have better luck getting your Tek4 repaired than I did.

How close will this focus on an object?

Asked by MichaelK October 4, 2018

I find it has good focus from an inch to about 14 inches.

Why is the screen blue when I turn on

Asked by Help1234 August 29, 2018

The camera is damaged and there is no signal going from the camera to the LCD unit.

Bought this over a year ago. The product itself works great for the price you pay. Went to charge it for the first time and the charger doesn't work so i had to buy a separate charger. Other than the charger, it works great.

the neatest item I have bought at Home Depot
I have already used it to locate a cal board that fell behind a MCC at our mill. The only thing that it needs is a video out port or a built in DVR to record it on a micro SD card .I have check inside and there is room to add it in & there is a standard Video line between the camera head and the display

Great product and very useful
I've been wanting one of these for a couple of years now. I finally received one for Christmas this year. I dropped my iPad stylus down a floor air vent a few weeks ago and it went far enough I could not see it. I ran a magnet around without any luck. After guiding the camera down it I could immediately see it. I dropped a magnet down with the camera just like you see on those surgery shows and latched onto my lost stylus. Within 5 minutes I had retrieved it thanks to this camera. The camera head was a lot smaller than I expected which should make it easy to drill holes to slide it into for wall inspections. It seems like I'm always needing to check in an area I cannot get to, so this will be great. The picture is in clear and in color, both were things I wondered about before purchasing. I couldn't find examples of either anywhere. The adjustable light is a very nice feature and really light up an area. The flexible arm is easy to bend and rigid enough to guide guide without it bending on its own. I'm not sure you can beat this product for the price.

Will update with use
The description is misleading. The camera head is not 7mm wide, which would make it .2755 inches [a little more than a quarter of an inch]. It's more like 5/8" - a little too wide to fit down a spark plug hole, which is why I selected this one over the Rigid. The Rigid unit is about 3/4". Controls are simple enough. On/off, the 180 degree view flip, a button for the 2x zoom, and a button to turn the light off and increase the amount of light. The camera itself is on the end of a flexible tube. You cannot control the direction, so you need to fish the head in and know where you're going before hand. For $100, not a bad tool, just know it is limited. I'll update the review when I've had time to actually employ the unit.

Fun tool
Thus tool is awesome the picture quality was much better than I expected

See what you can’t
This is a great tool to see what you can’t. Doing construction this tool takes a lot of guess work out of the job and prevents you from drilling into a water pipe that might be in your way. The bright lights gives you a great view of what is behind the wall.

Nice addition to my shop
Worked perfectly out of box. Comes with plug in charger for removable rechargable battery. Nice picture. I await my first 'needed' use beyond just playing with it, looking behind and under my shop tables for dropped items.
