What is battery life? Is there an AC connection so the battery would be used only as a backup?

1 year battery life. The remaining battery lifetime is displayed. No AC connection.

I've had mine for 6 months and the unit shows 90% battery remaining. There is no AC connection but there are configurable alerts - including low battery that you can have emailed, messaged to your phone, and they have a user-friendly mobile app that displays alerts as well. I'd say that you'd be okay unless whatever you are monitoring is remote and you do not visit at least yearly. I'll qualify that by saying my unit is in a location with reliable utilities and I regularly access the location so I am alerted by the sensor several times a week - I'm sure everyone's mileage may vary.

No AC connection. Installed battery four months ago, and is still at 90% life, (sensor gives you a readout of battery life).

Approximately 1yr 6mo and that's mounted in my safe, depends on use, I do not know of any AC connection. Still one of the best monitoring devices I've used.

My unit ran on batteries for 6 months and is still running. There is no ac connection

The device is not a battery. It converts 12 volt DC to AC current. It connects to a deep cycle battery provides a limited amount of backup power.

I'm not sure. I keep it plugged in. Sorry I can't be much help regarding the battery life.

I generally get around 4.5 hours. Most of the time I use the AC power. I use a hard drive not a solid state.

Gee I bought it awhile ago now and it plugs into an outlet, but I checked the description on Amazon and it doesn't say there's a backup battery. There is a little red light though, so if it were to turn off, you'd know it is not working.

If the device has a cable with a USB tip, the AbsolutePower will provide power and charge from an A/C outlet. It's not a backup battery source, though.

Not sure what you're asking. The stock battery life is about 2 hours (less if Wifi is on). You'll get about that for HDMI playback. Be sure to get the right HDMI type cable (non-ethernet), as the camera tends to be a bit finicky about what it likes to connect to. I've found that it's often easier to use the USB connection instead, if the monitor provides that.

I apologize to you for answering too late. Its not battery operated just only AC. Best Regards.

Require a power supply: No; Batteries: My book says "to provide back up power". Others have mentioned that the batteries don't last to long

ac power without a battery backup. I think it was motion sensor and would sometimes go on in dim lighting. I wouldn't buy another, it isn't worth it. Get this one instead. Brighter light, portable as a flash light and has battery back up. Still working great. Durofix RL435 Li-Ion 4V Plug-in Power Outage LED Light, 2-Pack Good Luck

We use AA batteries in it, but only while the regular batteries are charging. As others have stated, the AA batteries are rapidly depleted, so are really only worthwhile as backup.

Battery life is pretty good. I like it because it is rechargeable. Just plug it into an outlet.

9v battery is used as backup. The product description mentions this; however, the technical details say battery operated.... That's misleading

Yes, I run it primarily on ac. It will go a day or two in "monitor" mode depending upon how much activity it is recording. When you use screen to view what was recorded, it takes more battery power, same as smart phone screen. I have found battery to be adequate for my needs

Sure, there's a 12V outlet so if you have a separate inverter you could use it to create AC power. I have no idea how long it would last for any given application or exactly what maximum load it could handle. Since it's not designed for that, the manufacturer doesn't give provide any specs. But is it a substantial battery.

Overall the battery life is good. For a heavy user like me it lasts for 2.5 to 3.5hrs. its good. the only drawback is it has a inbuilt battery. which means its not user replaceable.
