Exacq built systems with redundant power supplies will emit an audible alarm in the event of a power failure. Here is how to silence the various models so you can enjoy peace and quiet while determining the cause of the failure.
The following photos show the location of the mute button on different models:

By default, Microsoft’s automatic Windows updates are not enabled on ExacqVision systems.
There are no known ExacqVision compatibility issues with any currently available Windows updates. However, if you decide to apply Windows updates your ExacqVision system, we suggest that you apply only the critical updates. Do not apply optional updates.
NOTE: If your Windows update settings are set to install your updates automatically, there is a risk of missing important video data during the reboot process. We suggest you choose an update method that does not automatically reboot your system such as “Check for Updates but let me choose whether to download and install them” or “Download updates but let me choose whether to install them”. If you choose to automatically install your Windows updates, make sure you setup an Automatic Maintenance window task to install during off peak hours.

If a hard drive in an Ubuntu Linux-based exacqVision system has an error in its file system, it could be marked as read only. This could cause a failure in the process of storing recorded video.
Starting with version 4.9, exacqVision detects whether a drive is read only. To determine whether a hard drive is read only in exacqVision 4.8 and earlier, try to save a temporary file to it by entering sudo touch /mnt/edvr/2/temp.file in a Terminal window (where “/mnt/edvr/2” is the name of the drive). If this command fails, the drive is read only. Alternatively, you can enter cat /proc/mounts and look for “ro” in the result.
To remount drives and change them to read-write, enter sudo mount -a.

exacqVision-Drives-Incorrectly-Marked-as-Read-Only-in-Ubuntu-Linux.pdfEL-SR and EL-ip exacqVision systems were manufactured with hard-drive caddies that contain a power switch starting in October 2011. If it appears that the hard drive in an exacqVision EL-SR or EL-ip system is not functioning even though the system is powered up, look on the front of the system and determine whether a hard drive power button is visible (see the button circled in red in the photograph below). If the green hard drive LED is not illuminated (see green circle), push the button to activate the hard drive.

On systems built by Exacq with Ubuntu version 18.04 and higher, the ability to use the operating system to configure automatic logins has been removed as a security measure.
You may, however, utilize the Exacq Kiosk User software to create kiosk user accounts and select whether or not a kiosk user account will automatically login.

Yes. Exacq has tested compatibility with the following configuration:
<br>
*Intel Q57TM Micro-ATX motherboard
*Two eDVR boards
*PCIe 1x Riser
<br>
At this time, Q57 is the only chipset that is supported for use with the PCIe 1x riser card.

Are-eDVR-boards-compatible-with-an-LGA-1156-motherboard.pdfRemote Desktop allows you to connect to your Windows-based ExacqVision server over a network connection and operate it as if you were using the system directly. This can be especially useful when you want to upgrade the server software.
Using Remote Desktop across public networks or the internet introduces many of the same security concerns associated with any internet connection. You must use a Windows operating system user account with sufficient privileges when connecting to the server. Exacq Support cannot assist in retrieving/resetting lost operating system passwords. It is also recommended that you connect to the ExacqVision server over a Virtual Private Network (VPN) for increased security.
<br>
Early versions of ExacqVision systems manufactured with the Windows 7 Embedded operating system did not have Remote Desktop. These systems were manufactured between January and February 2014.

The following procedures describe the process for replacing an eDVR board in a Windows-based exacqVision server. If you have an exacqVision server with multiple eDVR boards, complete both procedures; on a single-board system, you can skip directly to the second procedure.
NOTE: You must be logged in to Windows as an Adminsitrator to perform these procedures. If you are logged in as a User (the account used by default for normal operation of the system), select Log Off from the Start menu and click the Log Off button. When the login screen appears, log in as an Administrator. The default password for the Administrator account is “admin256.”
NOTE: It is recommended that you back up your settings before performing these procedures. To do this, run the exacqVision Client, open the Configuration tree, and select the system in which you will replace the eDVR board. Click Export Settings on the System tab, enter a name for the settings file, and click Save. If you need to restore the settings after the procedures, click Import Settings, browse to the settings file, and click Open.

TTL stands for Transistor-to-Transistor Logic, where the “logic” determines which values are high and low.
Standardized common TTL circuits operate with a 5-volt power supply. A TTL signal is defined as low when the voltage is measured between 0.0 V and 0.8 V with respect to the ground terminal, and high when measured between 2.2 V and 5 V (precise logic levels vary slightly between sub-types).
Exacq Hybrid NVR systems and the exacqVision USB I/O Module provide TTL inputs to activate input triggers and create output alarms. This allows exacqVision to interact with external devices/controls which may not provide means to be activated via software integration. The controllers in these systems follow the voltages listed above closely, as shown in the graphic below.
TTL uses a high/low indicator instead of the standard open/closed indicator of a contact closure. Many devices will accept this kind of information; if you have a device that works only with contact closures, you can find devices that convert TTL to contact closure.

Using Event Linking, exacqVision can activate external devices based on configured events, such as motion detection, analytic object detection, system health, input triggers, and more. See our User Training Videos on Event Linking and Event Monitoring, or refer to the User Manual, for information on configuration.
If you want your exacqVision Server to activate a 120VAC device during an event, it is recommended that you use the Xantech AC-1 switched AC outlet and a 120VAC power source/outlet. Event Linking must also be programmed in the exacqVision Client software.
If you want your exacqVision Server to activate a low-voltage device during an event, it is recommended that you use the Altronix RBSN-TTL relay and a 12-24VDC power supply. Event Linking must also be programmed in the exacqVision Client software.

Automation and control devices come in countless forms, from different manufacturers, models, and types of devices. But, the general purpose is to turn a circuit on or off to drive a load of some type. In electrical terms a “load” is the end output device. This could be a light bulb or a motor.
When electricity is applied to actuators or relays there is typically some sort of switching involved, whether a physical switch used by a person, a sensor, or a relay. The contacts switch between an open and closed position to either complete the circuit or break the circuit. Additionally, we tend to think of a completed circuit as being “on”, however when using relays our voltage could be applied to the normally open (NO) or the normally closed (NC) contact, which will determine the behavior of the circuit.
DRY CONTACTS require electricity to be sent to the load from some sort of external source. This is the case when using relays, including those found on Exacq Hybrid NVRs or the exacqVision USB I/O Module. Voltage is usually supplied through a “common wire”. In addition, the I/O terminals on many IP Cameras are relays as well.
WET CONTACTS provide power directly, where the current driving the load flows through the switch itself. Consider the circuit breaker panel for your home. The switch on the circuit breaker allows the current to flow through it to power the devices on that circuit.
Exacq Hybrid NVRs and the exacqVision USB I/O module provide both TTL and relay outputs. While TTLs provide electricity directly through solid-state switching, they usually provide too little current to do anything more useful than power a tiny LED, which is why the relay devices mentioned above are used to introduce external current. Whether you use AC or DC will depend on the device you are attempting to control.
Note, that in Figure 1 and Figure 2 above, both modules provide power to the load from an external source. This is required because the output terminals from Exacq do not provide enough voltage or amperage to drive most devices, only enough to signal another device of a change.
