Does it have a battery backup in case of power failure?

You must supply a power source, so battery backup would be a good option to think about.

Would the battery backup just be wired inline from the power source ? And would say a 12 volt alarm battery be suitable for this ?

I don't believe so. There is no battery back up. I haven't experienced an outage with it running, however. So if it were plugged in and turned on, it might just come back on.

Yes there is a battery backup!!! You might have to put the battery's in it.

No battery that I know of, but it does retain settings in the event of a power outage.

Yes, it comes with a plug and also has a battery installed for power backup.

Yes. Word of warning...if the power goes out, you will need to reset the timer. Also, this product lasted about one year and died on me. Did not replace with another. Went to Lowes and bought one that is digital and has battery backup ($25) seems to work great, but time will tell

The battery is a backup in case of power interruption. From a practical viewpoint you need a low voltage power supply.

The one that I bought came with a battery backup. When the power goes out the battery keeps the exit light on and the two side lamps go on.

the battery is for backup only..... in case electricity goes out. You still need to wire it.

No, it does not have a battery backup since it is a surge suppressor. I have used these Tripp Lite devices for many years in my job as an electronic technician and have never known one to fail. A device with a battery backup would be an Uninterruptible Power Supply, which is another good choice to protect your equipment, but somewhat more expensive.

Yes, but it has an option for batteries. I suppose it is in case of power outage.

The unit has a compartment for two button type batteries (supplied with the unit) that back up the memory if the power goes out. So the answer is: yes.

The power supply is an option. It uses a 9 volt battery (not supplied - no surprise there). When the power supply is used, the battery functions as a back-up.

It has a battery backup in case the power goes out but not sure how long that will last for

No. The battery is very weak, the camera shuts down in a few seconds when not connected to power.

While it does not support a battery power option, you could purchase a APC battery backup for the times when energy is down.

Yes, it does. It has a battery backup (9v) to keep programmed numbers and the message stored during any power outage.
